Verify current APIs against Vercel docs (use the Vercel docs MCP search + WebFetch) — do NOT rely on memory for: Neon Postgres provisioning via Vercel Marketplace, Vercel Cron config (vercel.json vs vercel.ts in Next 16), Drizzle ORM + Neon serverless driver setup, the AI SDK v6 `streamText` `onFinish` callback shape, and Basic-Auth via Next 16 middleware.\n\n## Current app (verified)\n- Next 16, React 19, `ai`@6, `@ai-sdk/react`@3, `@ai-sdk/anthropic`@3.0.70 (pinned), `zod`@4, `@upstash/ratelimit`+`@upstash/redis` (rate-limit only). No DB, no auth, no cron, no middleware.\n- `app/api/chat/route.ts`: rate-limit by IP → parse `{messages}` → `slice(-24)` → `convertToModelMessages` (async) → `streamText({ model, system(cached), tools: {suggest_page, log_unanswered, suggest_followups} })` → `toUIMessageStreamResponse()`. **No conversation id today.**\n- Tools in `lib/tools/`: `suggest_page` returns `{label,url,reason}` (intent from a 28-key enum in routes.ts); `log_unanswered` currently just `console.log`; `suggest_followups` echoes suggestions.\n- `app/embed/Chat.tsx`: `useChat` + `DefaultChatTransport({api:'/api/chat'})`; client persists messages to localStorage (`covalba-chat-v1`, 24h). No session/conversation id generated.\n- Deploy target: Vercel (the app is its own project). Has Upstash env optionally.\n\n## Goal (3 features)\n1. **Persistence** of conversations + analytics events (which page suggested, unanswered questions, token usage, model).\n2. **Monthly email report**: stats (nb conversations, messages, top suggested pages, % handled) + list of unanswered questions (to enrich knowledge.md). Sent by email (Resend).\n3. **Back office** (protected): dashboard KPIs, browse conversations (list + full thread view), unanswered-questions list (exportable).\n\n## Design constraints / preferences to honor\n- **Recommend Postgres (Neon via Vercel Marketplace) + Drizzle ORM** as the primary design (better for browsing/aggregation than Redis). Briefly note an Upstash-Redis-only fallback (no new infra) as an alternative, with its trade-offs.\n- **Conversation id**: generate client-side (crypto.randomUUID) stored in localStorage next to `covalba-chat-v1`, sent to the server. Show the cleanest way to inject it through `DefaultChatTransport` (header or body via `prepareSendMessagesRequest`) and read it in the route.\n- **Persist the turn in `streamText`'s `onFinish`** (gives final text + tool calls/results + usage) rather than wrapping the stream — confirm the exact `onFinish` payload fields in v6 (text, steps, toolCalls, toolResults, usage, finishReason, response messages). Persist: upsert conversation, append user message + assistant message, and derive events from tool calls (page suggested w/ intent+reason; unanswered w/ question; followups shown).\n- **Back office auth**: recommend simple **Basic Auth via `middleware.ts`** (env `ADMIN_USER`/`ADMIN_PASSWORD`) protecting `/admin/*` and the admin API. Show the middleware matcher + how it coexists with the public `/api/chat`, `/embed`, `/widget.js` (must NOT be protected).\n- **Monthly report**: **Vercel Cron** → protected `/api/cron/monthly-report` (validate `CRON_SECRET` / Vercel cron header). Aggregate previous calendar month, render an HTML+text email, send via **Resend** to a configurable recipient. Confirm exact cron declaration for this Next 16 app (vercel.json crons array? vercel.ts?) and the auth header Vercel sends.\n- **RGPD**: visitors may type personal data even though we never ask. Propose: a retention window (purge old rows via the same cron or a TTL), optional light PII masking (emails/phones) before storing message text, and NOT storing raw IP (hash or omit). Make these configurable.\n\n## Deliverables from you (concrete, code-forward)\n1. **DB schema** (Drizzle): tables `conversations`, `messages`, `events` (or your better design) with columns + indexes. Justify.\n2. **DB client setup** (`lib/db.ts`): Neon serverless driver + Drizzle; env detection so local dev without DB degrades gracefully (no crash — persistence becomes a no-op if `DATABASE_URL` unset, like the rate-limit fallback).\n3. **Route instrumentation**: exact diff-level changes to `app/api/chat/route.ts` (read conversation id, call `onFinish` to persist). Keep it non-blocking (don't fail the chat if DB write fails).\n4. **Client change**: conversation id generation + transport wiring in `Chat.tsx`.\n5. **Back office**: file list under `app/admin/` (dashboard, conversations list, conversation detail, unanswered) + the admin data queries. Server components reading Drizzle directly. Keep UI minimal (inline styles, no new UI dep).\n6. **Cron + email**: `app/api/cron/monthly-report/route.ts` + cron config file + a `lib/report.ts` aggregation + Resend email (re-add `resend` dep). Show the aggregation SQL/Drizzle queries.\n7. **Env vars** to add (`.env.example`): `DATABASE_URL`, `ADMIN_USER`, `ADMIN_PASSWORD`, `CRON_SECRET`, `RESEND_API_KEY`, `REPORT_FROM`, `REPORT_TO`, retention config.\n8. **Exact dependencies** + versions to install (drizzle-orm, drizzle-kit, @neondatabase/serverless, resend, …). Confirm published versions.\n9. Flag anything where the live API differs from the above.\n\nBe concrete and code-forward but concise. Do NOT write any files — return the design as your final message."},"uuid":"f5deaa47-a497-4b28-9104-ab7f7b01153e","timestamp":"2026-06-19T10:55:38.263Z","userType":"external","entrypoint":"cli","cwd":"/opt/projects/.covalba-refonte-worktrees/tom-test-chatbot/chatbot","sessionId":"df169d01-2f45-42ae-bcea-94edf9cd2c59","version":"2.1.183","gitBranch":"tom/test-chatbot","slug":"brief-chatbot-pure-swing"}

BEFORE invoking, check if the question is specific enough to research directly — if underspecified (e.g., \"what car to buy\" without budget/use-case/region), ask 2-3 clarifying questions to narrow scope. Then pass the refined question as args, weaving the answers in.\n- vercel:bootstrap\n- vercel:deploy\n- vercel:env\n- vercel:marketplace\n- vercel:status\n- vercel:ai-gateway\n- vercel:ai-sdk\n- vercel:auth\n- vercel:bootstrap\n- vercel:chat-sdk\n- vercel:deployments-cicd\n- vercel:env-vars\n- vercel:knowledge-update\n- vercel:marketplace\n- vercel:microfrontends\n- vercel:next-cache-components\n- vercel:next-forge\n- vercel:next-upgrade\n- vercel:nextjs\n- vercel:react-best-practices\n- vercel:routing-middleware\n- vercel:runtime-cache\n- vercel:shadcn\n- vercel:turbopack\n- vercel:vercel-agent\n- vercel:vercel-cli\n- vercel:vercel-firewall\n- vercel:vercel-functions\n- vercel:vercel-sandbox\n- vercel:vercel-storage\n- vercel:verification\n- vercel:workflow: Vercel Workflow DevKit (WDK) expert guidance. Use when building durable workflows, long-running tasks, API routes or agents that need pause/resume, retries, step-based execution, or crash-safe orchestration with Vercel Workflow.\n- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by running the app and observing behavior. Use when asked to verify a PR, confirm a fix works, test a change manually, check that a feature works, or validate local changes before pushing.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init\n- review\n- security-review","skillCount":134,"isInitial":true,"names":["adapt","animate","arrange","audit","bolder","bun-to-next","clarify","colorize","critique","delight","design-taste-frontend","distill","excalidraw-diagram","extract","feedbackpin","full-output-enforcement","gsap-core","gsap-frameworks","gsap-performance","gsap-plugins","gsap-react","gsap-scrolltrigger","gsap-timeline","gsap-utils","harden","high-end-visual-design","impeccable","industrial-brutalist-ui","minimalist-ui","netlify-cli","nextjs-wordpress-headless","normalize","onboard","optimize","overdrive","paf-site-magic","polish","quieter","redesign-existing-projects","refero-design","scheduled-actions","seo","seo-audit","seo-backlinks","seo-competitor-pages","seo-content","seo-dataforseo","seo-firecrawl","seo-geo","seo-google","seo-hreflang","seo-image-gen","seo-images","seo-local","seo-maps","seo-page","seo-plan","seo-programmatic","seo-schema","seo-sitemap","seo-technical","shape","stitch-design-taste","typeset","brainstorming","brutalist-skill","check-conflicts","dispatching-parallel-agents","executing-plans","feedbackpin","finishing-a-development-branch","minimalist-skill","output-skill","receiving-code-review","redesign-skill","requesting-code-review","soft-skill","stitch-skill","subagent-driven-development","systematic-debugging","taste-skill","test-driven-development","using-git-worktrees","using-superpowers","verification-before-completion","writing-plans","writing-skills","handoff","deep-research","vercel:bootstrap","vercel:deploy","vercel:env","vercel:marketplace","vercel:status","vercel:ai-gateway","vercel:ai-sdk","vercel:auth","vercel:bootstrap","vercel:chat-sdk","vercel:deployments-cicd","vercel:env-vars","vercel:knowledge-update","vercel:marketplace","vercel:microfrontends","vercel:next-cache-components","vercel:next-forge","vercel:next-upgrade","vercel:nextjs","vercel:react-best-practices","vercel:routing-middleware","vercel:runtime-cache","vercel:shadcn","vercel:turbopack","vercel:vercel-agent","vercel:vercel-cli","vercel:vercel-firewall","vercel:vercel-functions","vercel:vercel-sandbox","vercel:vercel-storage","vercel:verification","vercel:workflow","update-config","keybindings-help","verify","code-review","simplify","fewer-permission-prompts","loop","schedule","claude-api","run","init","review","security-review"]},"type":"attachment","uuid":"d20fe538-627b-48e1-bf26-e37c0f0831c2","timestamp":"2026-06-19T10:55:38.297Z","userType":"external","entrypoint":"cli","cwd":"/opt/projects/.covalba-refonte-worktrees/tom-test-chatbot/chatbot","sessionId":"df169d01-2f45-42ae-bcea-94edf9cd2c59","version":"2.1.183","gitBranch":"tom/test-chatbot","slug":"brief-chatbot-pure-swing"}

By using a specific syntax called a [cron expression](#cron-expressions), you can define the frequency and timing of each task. This helps improve efficiency and ensures that important processes are performed consistently.\n\nSome common use cases of cron jobs are:\n\n- Automating backups and archiving them\n- Sending email and Slack notifications\n- Updating Stripe subscription quantities\n\nVercel supports cron jobs for [Vercel Functions](/docs/functions). Cron jobs can be added through [`vercel.json`](/docs/project-configuration) or the [Build Output API](/docs/build-output-api/v3/configuration#crons).\n\nSee [Managing Cron Jobs](/docs/cron-jobs/manage-cron-jobs) for information on duration, error handling, deployments, concurrency control, and local execution. To learn about usage limits and pricing information, see the [Usage and Pricing](/docs/cron-jobs/usage-and-pricing) page.\n\n## Getting started with cron jobs\n\nLearn how to set up and configure cron jobs for your project using our [Quickstart](/docs/cron-jobs/quickstart) guide.\n\n## How cron jobs work\n\nTo trigger a cron job, Vercel makes an HTTP GET request to your project's production deployment URL, using the `path` provided in your project's `vercel.json` file. An example endpoint Vercel would make a request to in order to trigger a cron job might be: `https://*.vercel.app/api/cron`.\n\nVercel Functions triggered by a cron job on Vercel will always contain `vercel-cron/1.0` as the user agent. Each request also includes an `x-vercel-cron-schedule` header containing the cron expression that triggered the invocation (e.g., `0 5 * * *`). You can use this header to determine which schedule triggered your function when multiple cron jobs share the same path.\n\n## Cron expressions\n\nVercel supports the following cron expressions format:\n\n| Field        | Value Range     | Example Expression | Description                                          |\n| ------------ | --------------- | ------------------ | ---------------------------------------------------- |\n| Minute       | 0 - 59          | `5 * * * *`        | Triggers at 5 minutes past the hour                  |\n| Hour         | 0 - 23          | `* 5 * * *`        | Triggers every minute, between 05:00 AM and 05:59 AM |\n| Day of Month | 1 - 31          | `* * 5 * *`        | Triggers every minute, on day 5 of the month         |\n| Month        | 1 - 12          | `* * * 5 *`        | Triggers every minute, only in May                   |\n| Day of Week  | 0 - 6 (Sun-Sat) | `* * * * 5`        | Triggers every minute, only on Friday                |\n\n### Validate cron expressions\n\nTo validate your cron expressions, you can use the following tool to quickly verify the syntax and timing of your scheduled tasks to ensure they run as intended.\n\nYou can also use [crontab guru](https://crontab.guru/) to validate your cron expressions.\n\n### Cron expression limitations\n\n- Cron jobs on Vercel do not support alternative expressions like `MON`, `SUN`, `JAN`, or `DEC`\n- You cannot configure both day of the month and day of the week at the same time.

Select your project from the Vercel dashboard\n2. Open **Settings** in the sidebar and select [**Cron Jobs**](https://vercel.com/d?to=%2F%5Bteam%5D%2F%5Bproject%5D%2Fsettings%2Fcron-jobs\\&title=Go+to+Cron+Jobs+settings)\n\n## Cron jobs maintenance\n\n- **Updating Cron Jobs**: Change the [expression](/docs/cron-jobs#cron-expressions) in `vercel.json` file or the function's configuration, and then redeploy\n- **Deleting Cron Jobs**: Remove the configuration from the `vercel.json` file or the function's configuration, and then redeploy\n- **Disabling Cron Jobs**: Click the **Disable Cron Jobs** button\n\n> **⚠️ Warning:** Disabled cron jobs will still be listed and will count towards your [cron jobs\n> limits](/docs/cron-jobs/usage-and-pricing)\n\n## Securing cron jobs\n\nIt is possible to secure your cron job invocations by adding an environment variable called `CRON_SECRET` to your Vercel project. We recommend using a random string of at least 16 characters for the value of `CRON_SECRET`. A password generator, like [1Password](https://1password.com/password-generator/), can be used to create one.\n\nThe value of the variable will be automatically sent as an `Authorization` header when Vercel invokes your cron job. Your endpoint can then compare both values, the authorization header and the environment variable, to verify the authenticity of the request.\n\n> **💡 Note:** You can use App Router [Route\n> Handlers](https://nextjs.org/docs/app/building-your-application/routing/route-handlers)\n> to secure your cron jobs, even when using the Pages Router.\n\n```ts filename=\"app/api/cron/route.ts\" framework=nextjs\nimport type { NextRequest } from 'next/server';\n\nexport function GET(request: NextRequest) {\n  const authHeader = request.headers.get('authorization');\n  const cronSecret = process.env.CRON_SECRET;\n\n  if (!cronSecret || authHeader !== `Bearer ${cronSecret}`) {\n    return new Response('Unauthorized', {\n      status: 401,\n    });\n  }\n\n  return Response.json({ success: true });\n}\n```\n\n```js filename=\"app/api/cron/route.js\" framework=nextjs\nexport function GET(request) {\n  const authHeader = request.headers.get('authorization');\n  const cronSecret = process.env.CRON_SECRET;\n\n  if (!cronSecret || authHeader !== `Bearer ${cronSecret}`) {\n    return new Response('Unauthorized', {\n      status: 401,\n    });\n  }\n\n  return Response.json({ success: true });\n}\n```\n\n```ts filename=\"app/api/cron/route.ts\" framework=nextjs-app\nimport type { NextRequest } from 'next/server';\n\nexport function GET(request: NextRequest) {\n  const authHeader = request.headers.get('authorization');\n  const cronSecret = process.env.CRON_SECRET;\n\n  if (!cronSecret || authHeader !== `Bearer ${cronSecret}`) {\n    return new Response('Unauthorized', {\n      status: 401,\n    });\n  }\n\n  return Response.json({ success: true });\n}\n```\n\n```js filename=\"app/api/cron/route.js\" framework=nextjs-app\nexport function GET(request) {\n  const authHeader = request.headers.get('authorization');\n  const cronSecret = process.env.CRON_SECRET;\n\n  if (!cronSecret || authHeader !== `Bearer ${cronSecret}`) {\n    return new Response('Unauthorized', {\n      status: 401,\n    });\n  }\n\n  return Response.json({ success: true });\n}\n```\n\n```ts filename=\"api/cron/route.ts\" framework=other\nimport type { VercelRequest, VercelResponse } from '@vercel/node';\n\nexport default function handler(\n  request: VercelRequest,\n  response: VercelResponse,\n) {\n  const authHeader = request.headers.authorization;\n  const cronSecret = process.env.CRON_SECRET;\n\n  if (!cronSecret || authHeader !== `Bearer ${cronSecret}`) {\n    return response.status(401).json({ success: false });\n  }\n\n  response.status(200).json({ success: true });\n}\n```\n\n```js filename=\"api/cron/route.js\" framework=other\nexport default function handler(request, response) {\n  const authHeader = request.headers.authorization;\n  const cronSecret = process.env.CRON_SECRET;\n\n  if (!cronSecret || authHeader !== `Bearer ${cronSecret}`) {\n    return response.status(401).json({ success: false });\n  }\n\n  response.status(200).json({ success: true });\n}\n```\n\nThe `authorization` header will have the `Bearer` prefix for the value.\n\n> For \\['nextjs-app', 'nextjs']:\n\nFor those using TypeScript versions below 5.2, it's important to adapt the code to `import NextResponse from 'next/server'` and use `NextResponse.json` for the response. This ensures compatibility with earlier TypeScript versions in Next.js applications. In TypeScript 5.2 and above, the standard `new Response` pattern should be used.\n\n## Reading the cron schedule header\n\nEvery cron job request includes the `x-vercel-cron-schedule` header, which contains the cron expression that triggered the invocation. This is useful when multiple cron jobs share the same path but run on different schedules:\n\n```json filename=\"vercel.json\"\n{\n  \"$schema\": \"https://openapi.vercel.sh/vercel.json\",\n  \"crons\": [\n    {\n      \"path\": \"/api/sync\",\n      \"schedule\": \"*/5 * * * *\"\n    },\n    {\n      \"path\": \"/api/sync\",\n      \"schedule\": \"0 0 * * *\"\n    }\n  ]\n}\n```\n\nYou can read the header in your cron route to determine which schedule triggered the request:\n\n```ts filename=\"app/api/sync/route.ts\" framework=nextjs\nimport type { NextRequest } from 'next/server';\n\nexport function GET(request: NextRequest) {\n  const schedule = request.headers.get('x-vercel-cron-schedule');\n\n  if (schedule === '0 0 * * *') {\n    // Run full daily sync\n  } else {\n    // Run incremental sync\n  }\n\n  return Response.json({ success: true });\n}\n```\n\n```js filename=\"app/api/sync/route.js\" framework=nextjs\nexport function GET(request) {\n  const schedule = request.headers.get('x-vercel-cron-schedule');\n\n  if (schedule === '0 0 * * *') {\n    // Run full daily sync\n  } else {\n    // Run incremental sync\n  }\n\n  return Response.json({ success: true });\n}\n```\n\n```ts filename=\"app/api/sync/route.ts\" framework=nextjs-app\nimport type { NextRequest } from 'next/server';\n\nexport function GET(request: NextRequest) {\n  const schedule = request.headers.get('x-vercel-cron-schedule');\n\n  if (schedule === '0 0 * * *') {\n    // Run full daily sync\n  } else {\n    // Run incremental sync\n  }\n\n  return Response.json({ success: true });\n}\n```\n\n```js filename=\"app/api/sync/route.js\" framework=nextjs-app\nexport function GET(request) {\n  const schedule = request.headers.get('x-vercel-cron-schedule');\n\n  if (schedule === '0 0 * * *') {\n    // Run full daily sync\n  } else {\n    // Run incremental sync\n  }\n\n  return Response.json({ success: true });\n}\n```\n\n```ts filename=\"api/sync.ts\" framework=other\nimport type { VercelRequest, VercelResponse } from '@vercel/node';\n\nexport default function handler(\n  request: VercelRequest,\n  response: VercelResponse,\n) {\n  const schedule = request.headers['x-vercel-cron-schedule'];\n\n  if (schedule === '0 0 * * *') {\n    // Run full daily sync\n  } else {\n    // Run incremental sync\n  }\n\n  response.status(200).json({ success: true });\n}\n```\n\n```js filename=\"api/sync.js\" framework=other\nexport default function handler(request, response) {\n  const schedule = request.headers['x-vercel-cron-schedule'];\n\n  if (schedule === '0 0 * * *') {\n    // Run full daily sync\n  } else {\n    // Run incremental sync\n  }\n\n  response.status(200).json({ success: true });\n}\n```\n\n## Cron job duration\n\nThe duration limits for Cron jobs are identical to those of [Vercel Functions](/docs/functions#limits). See the [`maxDuration`](/docs/functions/runtimes#max-duration) documentation for more information.\n\nIn most cases, these limits are sufficient. However, if you need more processing time, it's recommended to split your cron jobs into different units or distribute your workload by combining cron jobs with regular HTTP requests with your API.\n\n## Cron job error handling\n\nVercel will not retry an invocation if a cron job fails. You can check for error [logs](/docs/runtime-logs) through the **View Log** button in the **Cron Jobs** section in the sidebar.\n\n## Cron jobs with dynamic routes\n\nCron jobs can be created for [dynamic routes](https://nextjs.org/docs/routing/dynamic-routes):\n\n```json filename=\"vercel.json\"\n{\n  \"$schema\": \"https://openapi.vercel.sh/vercel.json\",\n  \"crons\": [\n    {\n      \"path\": \"/api/sync-slack-team/T0CAQ10TZ\",\n      \"schedule\": \"0 5 * * *\"\n    },\n    {\n      \"path\": \"/api/sync-slack-team/T4BOE34OP\",\n      \"schedule\": \"0 5 * * *\"\n    }\n  ]\n}\n```\n\n## Handling nonexistent paths\n\nIf you create a cron job for a path that doesn't exist, it generates a [404 error](/docs/errors/platform-error-codes#404:-not_found). However, **Vercel still executes your cron job**. You can analyze your logs to check if there are any issues.\n\n## Cron jobs and deployments\n\nCreating a new deployment will not interrupt your running cron jobs; they will continue until they finish.\n\n## Controlling cron job concurrency\n\nIf your cron job runs longer than the interval between invocations, Vercel can trigger a second instance while the first is still running. This can lead to race conditions, duplicate processing, or data corruption.\n\nTo prevent concurrent runs, use a lock mechanism like [Redis distributed locks](https://redis.io/docs/latest/develop/clients/patterns/distributed-locks/) in your cron job. A lock ensures only one instance runs at a time by checking if another instance is already active before starting.\n\nYou can also prevent overlapping runs by:\n\n- **Reducing execution time**: Optimize your job to finish before the next invocation\n- **Setting timeouts**: Use [`maxDuration`](/docs/functions/runtimes#max-duration) to force long-running jobs to stop\n- **Increasing the interval**: Run your cron job less frequently\n\n### Cron job delivery and idempotency\n\nCron job delivery is best effort. Most invocations run as scheduled, but occasional transient network errors can prevent a request from reaching your function. In those cases, your function does not execute, and no runtime log is created for that scheduled run.\n\nCron delivery can also occasionally invoke the same scheduled run more than once. Because of this, cron jobs should be resilient to both missed runs and duplicate runs.\n\nDesign your operations to be **idempotent** and reconciliation-based so each run can safely reprocess outstanding work since the last successful run. For example:\n\n- **Good**: \"Set user status to active\" (running twice has the same effect)\n- **Bad**: \"Increment user credit by 10\" (running twice doubles the credit)\n\nTo make operations resilient:\n\n- Use unique IDs to track which events you've already processed\n- Check state before making changes (e.g., \"if not already active, then activate\")\n- Store results with timestamps or version numbers\n- Query and process all work since the last successful run to catch up after a missed invocation\n\nUse both locks (to prevent concurrent runs) and idempotent reconciliation (to handle duplicate or missed runs safely) for the most reliable cron jobs.\n\n## Running cron jobs locally\n\nCron jobs are API routes. You can run them locally by making a request to their endpoint. For example, if your cron job is in `/api/cron`, you could visit the following endpoint in your browser: `http://localhost:3000/api/cron`. You should be aware that while your browser may follow redirects, [cron job invocations in production will not](#cron-jobs-and-redirects) follow redirects.\n\nThere is currently no support for `vercel dev`, `next dev`, or other framework-native local development servers.\n\n## Cron jobs and redirects\n\nCron jobs do not follow redirects. When a cron-triggered endpoint returns a 3xx redirect status code, the job completes without further requests. Redirect responses are treated as final for each invocation.\n\nThe view logs button on the cron job overview can be used to verify the response of the invocations and gain further insights.\n\n## Cron jobs logs\n\nCron jobs are logged as function invocations from the **Logs** section in your project dashboard sidebar(/dashboard). You can view the logs for a cron job from the list on the [Cron jobs settings page](/docs/cron-jobs/manage-cron-jobs#viewing-cron-jobs) of the project:\n\n1. From the list of cron jobs, select **View Logs**.\n2. This will take you to the [runtime logs](/docs/runtime-logs#request-path) view with a `requestPath` filter to your cron job such as `requestPath:/api/my-cron-job`.\n\nSee [how to view runtime logs](/docs/runtime-logs#view-runtime-logs) for more information.\n\nNote that when cron jobs respond with a redirect or a cached response, they will not be shown in the logs.\n\n## Cron jobs accuracy\n\nHobby users have two cron job restrictions. First, cron jobs can only run [once per day](/docs/cron-jobs/usage-and-pricing#hobby-scheduling-limits). Expressions that run more frequently will fail deployment. Second, Vercel may invoke these cron jobs at any point within the specified hour to help distribute load across all accounts. For example, an expression like `0 8 * * *` could trigger an invocation anytime between `08:00:00` and `08:59:59`.\n\nFor all other teams, cron jobs will be invoked within the minute specified. For instance, the expression `5 8 * * *` would trigger an invocation between `08:05:00` and `08:05:59`.\n\n## Rollbacks with cron jobs\n\nIf you [Instant Rollback](/docs/instant-rollback) to a previous deployment, active cron jobs **will not** be updated. They will continue to run as scheduled until they are manually disabled or updated.\n\n\n---\n\n[View full sitemap](/docs/sitemap)\n"}]},"uuid":"e35aa0c3-d6b3-47a1-8202-01c2ec03eefb","timestamp":"2026-06-19T10:55:57.265Z","toolUseResult":{"bytes":14142,"code":200,"codeText":"OK","result":"---\ntitle: Managing Cron Jobs\nproduct: vercel\nurl: /docs/cron-jobs/manage-cron-jobs\ncanonical_url: \"https://vercel.com/docs/cron-jobs/manage-cron-jobs\"\nlast_updated: 2026-06-02\ntype: reference\nprerequisites:\n  - /docs/cron-jobs\nrelated:\n  - /docs/cron-jobs\n  - /docs/cron-jobs/usage-and-pricing\n  - /docs/functions\n  - /docs/functions/runtimes\n  - /docs/runtime-logs\nsummary: Learn how to manage Cron Jobs effectively in Vercel.

Select your project from the Vercel dashboard\n2. Open **Settings** in the sidebar and select [**Cron Jobs**](https://vercel.com/d?to=%2F%5Bteam%5D%2F%5Bproject%5D%2Fsettings%2Fcron-jobs\\&title=Go+to+Cron+Jobs+settings)\n\n## Cron jobs maintenance\n\n- **Updating Cron Jobs**: Change the [expression](/docs/cron-jobs#cron-expressions) in `vercel.json` file or the function's configuration, and then redeploy\n- **Deleting Cron Jobs**: Remove the configuration from the `vercel.json` file or the function's configuration, and then redeploy\n- **Disabling Cron Jobs**: Click the **Disable Cron Jobs** button\n\n> **⚠️ Warning:** Disabled cron jobs will still be listed and will count towards your [cron jobs\n> limits](/docs/cron-jobs/usage-and-pricing)\n\n## Securing cron jobs\n\nIt is possible to secure your cron job invocations by adding an environment variable called `CRON_SECRET` to your Vercel project. We recommend using a random string of at least 16 characters for the value of `CRON_SECRET`. A password generator, like [1Password](https://1password.com/password-generator/), can be used to create one.\n\nThe value of the variable will be automatically sent as an `Authorization` header when Vercel invokes your cron job. Your endpoint can then compare both values, the authorization header and the environment variable, to verify the authenticity of the request.\n\n> **💡 Note:** You can use App Router [Route\n> Handlers](https://nextjs.org/docs/app/building-your-application/routing/route-handlers)\n> to secure your cron jobs, even when using the Pages Router.\n\n```ts filename=\"app/api/cron/route.ts\" framework=nextjs\nimport type { NextRequest } from 'next/server';\n\nexport function GET(request: NextRequest) {\n  const authHeader = request.headers.get('authorization');\n  const cronSecret = process.env.CRON_SECRET;\n\n  if (!cronSecret || authHeader !== `Bearer ${cronSecret}`) {\n    return new Response('Unauthorized', {\n      status: 401,\n    });\n  }\n\n  return Response.json({ success: true });\n}\n```\n\n```js filename=\"app/api/cron/route.js\" framework=nextjs\nexport function GET(request) {\n  const authHeader = request.headers.get('authorization');\n  const cronSecret = process.env.CRON_SECRET;\n\n  if (!cronSecret || authHeader !== `Bearer ${cronSecret}`) {\n    return new Response('Unauthorized', {\n      status: 401,\n    });\n  }\n\n  return Response.json({ success: true });\n}\n```\n\n```ts filename=\"app/api/cron/route.ts\" framework=nextjs-app\nimport type { NextRequest } from 'next/server';\n\nexport function GET(request: NextRequest) {\n  const authHeader = request.headers.get('authorization');\n  const cronSecret = process.env.CRON_SECRET;\n\n  if (!cronSecret || authHeader !== `Bearer ${cronSecret}`) {\n    return new Response('Unauthorized', {\n      status: 401,\n    });\n  }\n\n  return Response.json({ success: true });\n}\n```\n\n```js filename=\"app/api/cron/route.js\" framework=nextjs-app\nexport function GET(request) {\n  const authHeader = request.headers.get('authorization');\n  const cronSecret = process.env.CRON_SECRET;\n\n  if (!cronSecret || authHeader !== `Bearer ${cronSecret}`) {\n    return new Response('Unauthorized', {\n      status: 401,\n    });\n  }\n\n  return Response.json({ success: true });\n}\n```\n\n```ts filename=\"api/cron/route.ts\" framework=other\nimport type { VercelRequest, VercelResponse } from '@vercel/node';\n\nexport default function handler(\n  request: VercelRequest,\n  response: VercelResponse,\n) {\n  const authHeader = request.headers.authorization;\n  const cronSecret = process.env.CRON_SECRET;\n\n  if (!cronSecret || authHeader !== `Bearer ${cronSecret}`) {\n    return response.status(401).json({ success: false });\n  }\n\n  response.status(200).json({ success: true });\n}\n```\n\n```js filename=\"api/cron/route.js\" framework=other\nexport default function handler(request, response) {\n  const authHeader = request.headers.authorization;\n  const cronSecret = process.env.CRON_SECRET;\n\n  if (!cronSecret || authHeader !== `Bearer ${cronSecret}`) {\n    return response.status(401).json({ success: false });\n  }\n\n  response.status(200).json({ success: true });\n}\n```\n\nThe `authorization` header will have the `Bearer` prefix for the value.\n\n> For \\['nextjs-app', 'nextjs']:\n\nFor those using TypeScript versions below 5.2, it's important to adapt the code to `import NextResponse from 'next/server'` and use `NextResponse.json` for the response.

See [Migration to Proxy](#migration-to-proxy) for more details.\n\nThe `proxy.js|ts` file is used to write [Proxy](/docs/app/getting-started/proxy) and run code on the server before a request is completed. Then, based on the incoming request, you can modify the response by rewriting, redirecting, modifying the request or response headers, or responding directly.\n\nProxy executes before routes are rendered. It's particularly useful for implementing custom server-side logic like authentication, logging, or handling redirects.\n\n> **Good to know**:\n>\n> Proxy is meant to be invoked separately of your render code and in optimized cases deployed to your CDN for fast redirect/rewrite handling, you should not attempt relying on shared modules or globals.\n>\n> To pass information from Proxy to your application, use [headers](#setting-headers), [cookies](#using-cookies), [rewrites](/docs/app/api-reference/functions/next-response#rewrite), [redirects](/docs/app/api-reference/functions/next-response#redirect), or the URL.\n\nCreate a `proxy.ts` (or `.js`) file in the project root, or inside `src` if applicable, so that it is located at the same level as `pages` or `app`.\n\nIf you’ve customized [`pageExtensions`](/docs/app/api-reference/config/next-config-js/pageExtensions), for example to `.page.ts` or `.page.js`, name your file `proxy.page.ts` or `proxy.page.js` accordingly.\n\n```tsx filename=\"proxy.ts\" switcher\nimport { NextResponse } from 'next/server'\nimport type { NextRequest } from 'next/server'\n\n// This function can be marked `async` if using `await` inside\nexport function proxy(request: NextRequest) {\n  return NextResponse.redirect(new URL('/home', request.url))\n}\n\nexport const config = {\n  matcher: '/about/:path*',\n}\n```\n\n```js filename=\"proxy.js\" switcher\nimport { NextResponse } from 'next/server'\n\n// This function can be marked `async` if using `await` inside\nexport function proxy(request) {\n  return NextResponse.redirect(new URL('/home', request.url))\n}\n\nexport const config = {\n  matcher: '/about/:path*',\n}\n```\n\n## Exports\n\n### Proxy function\n\nThe file must export a single function, either as a default export or named `proxy`. Note that multiple proxy from the same file are not supported.\n\n```js filename=\"proxy.js\"\n// Example of default export\nexport default function proxy(request) {\n  // Proxy logic\n}\n```\n\n### Config object (optional)\n\nOptionally, a config object can be exported alongside the Proxy function. This object includes the [matcher](#matcher) to specify paths where the Proxy applies.\n\n### Matcher\n\nThe `matcher` option allows you to target specific paths for the Proxy to run on.\n\nWithout a `matcher`, Proxy runs on **every request**, including static files (`_next/static`), image optimizations (`_next/image`), and assets in the `public/` folder. Consider using a [negative match pattern](#negative-matching) to exclude these paths, otherwise auth logic or redirects can unintentionally block CSS, JS, or images from loading.\n\nYou can specify paths in several ways:\n\n* For a single path: Directly use a string to define the path, like `'/about'`.\n* For multiple paths: Use an array to list multiple paths, such as `matcher: ['/about', '/contact']`, which applies the Proxy to both `/about` and `/contact`.\n\n```js filename=\"proxy.js\"\nexport const config = {\n  matcher: ['/about/:path*', '/dashboard/:path*'],\n}\n```\n\nAdditionally, the `matcher` option supports complex path specifications using regular expressions. For example, you can exclude certain paths with a regular expression matcher:\n\n```js filename=\"proxy.js\"\nexport const config = {\n  matcher: [\n    // Exclude API routes, static files, image optimizations, and .png files\n    '/((?!api|_next/static|_next/image|.*\\\\.png$).*)',\n  ],\n}\n```\n\nThis enables precise control over which paths to include or exclude.\n\nThe `matcher` option accepts an array of objects with the following keys:\n\n* `source`: The path or pattern used to match the request paths. It can be a string for direct path matching or a pattern for more complex matching.\n* `locale` (optional): A boolean that, when set to `false`, ignores locale-based routing in path matching.\n* `has` (optional): Specifies conditions based on the presence of specific request elements such as headers, query parameters, or cookies.\n* `missing` (optional): Focuses on conditions where certain request elements are absent, like missing headers or cookies.\n\n```js filename=\"proxy.js\"\nexport const config = {\n  matcher: [\n    {\n      source: '/api/:path*',\n      locale: false,\n      has: [\n        { type: 'header', key: 'Authorization', value: 'Bearer Token' },\n        { type: 'query', key: 'userId', value: '123' },\n      ],\n      missing: [{ type: 'cookie', key: 'session', value: 'active' }],\n    },\n  ],\n}\n```\n\nThe `source` path patterns:\n\n1. MUST start with `/`\n2. Can include named parameters: `/about/:path` matches `/about/a` and `/about/b` but not `/about/a/c`\n3. Can have modifiers on named parameters (starting with `:`): `/about/:path*` matches `/about/a/b/c` because `*` is *zero or more*. `?` is *zero or one* and `+` *one or more*\n4. Can use regular expression enclosed in parenthesis: `/about/(.*)` is the same as `/about/:path*`\n5. Are anchored to the start of the path: `/about` matches `/about` and `/about/team` but not `/blog/about`\n\nRead more details on [path-to-regexp](https://github.com/pillarjs/path-to-regexp#path-to-regexp-1) documentation.\n\n> **Good to know**:\n>\n> * The `matcher` values need to be constants so they can be statically analyzed at build-time. Dynamic values such as variables will be ignored.\n> * For backward compatibility, Next.js always considers `/public` as `/public/index`. Therefore, a matcher of `/public/:path` will match.\n\n## Params\n\n### `request`\n\nWhen defining Proxy, the default export function accepts a single parameter, `request`. This parameter is an instance of `NextRequest`, which represents the incoming HTTP request.\n\n```tsx filename=\"proxy.ts\" switcher\nimport type { NextRequest } from 'next/server'\n\nexport function proxy(request: NextRequest) {\n  // Proxy logic goes here\n}\n```\n\n```js filename=\"proxy.js\" switcher\nexport function proxy(request) {\n  // Proxy logic goes here\n}\n```\n\nIf you prefer a shorthand, you can use the `NextProxy` type. It infers the parameter types for both `request` (`NextRequest`) and `event` (`NextFetchEvent`) automatically:\n\n```tsx filename=\"proxy.ts\"\nimport type { NextProxy } from 'next/server'\n\nexport const proxy: NextProxy = (request, event) => {\n  event.waitUntil(Promise.resolve())\n  return Response.json({ pathname: request.nextUrl.pathname })\n}\n```\n\n> **Good to know**:\n>\n> * `NextRequest` is a type that represents incoming HTTP requests in Next.js Proxy, whereas [`NextResponse`](#nextresponse) is a class used to manipulate and send back HTTP responses.\n\n## NextResponse\n\nThe `NextResponse` API allows you to:\n\n* `redirect` the incoming request to a different URL\n* `rewrite` the response by displaying a given URL\n* Set request headers for API Routes, `getServerSideProps`, and `rewrite` destinations\n* Set response cookies\n* Set response headers\n\nTo produce a response from Proxy, you can:\n\n1. `rewrite` to a route ([Page](/docs/app/api-reference/file-conventions/page) or [Route Handler](/docs/app/api-reference/file-conventions/route)) that produces a response\n2. return a `NextResponse` directly. See [Producing a Response](#producing-a-response)\n\n> **Good to know**: For redirects, you can also use `Response.redirect` instead of `NextResponse.redirect`.\n\n## Execution order\n\nProxy will be invoked for **every route in your project**. Given this, it's crucial to use [matchers](#matcher) to precisely target or exclude specific routes. The following is the execution order:\n\n1. `headers` from `next.config.js`\n2. `redirects` from `next.config.js`\n3. Proxy (`rewrites`, `redirects`, etc.)\n4. `beforeFiles` (`rewrites`) from `next.config.js`\n5. Filesystem routes (`public/`, `_next/static/`, `pages/`, `app/`, etc.)\n6. `afterFiles` (`rewrites`) from `next.config.js`\n7. Dynamic Routes (`/blog/[slug]`)\n8. `fallback` (`rewrites`) from `next.config.js`\n\n> **Good to know:** [Server Functions](/docs/app/api-reference/directives/use-server) are not separate routes in this chain. They are handled as POST requests to the route where they are used, so a Proxy matcher that excludes a path will also skip Server Function calls on that path.\n>\n> A matcher change or a refactor that moves a Server Function to a different route can silently remove Proxy coverage. Always verify authentication and authorization inside each Server Function rather than relying on Proxy alone. See the [Data Security guide](/docs/app/guides/data-security#authentication-and-authorization) for recommended patterns.\n\n## Runtime\n\nProxy defaults to using the Node.js runtime. The [`runtime`](/docs/app/api-reference/file-conventions/route-segment-config/runtime) config option is not available in Proxy files. Setting the `runtime` config option in Proxy will throw an error.\n\n## Advanced Proxy flags\n\nIn `v13.1` of Next.js two additional flags were introduced for proxy, `skipProxyUrlNormalize` (formerly `skipMiddlewareUrlNormalize`) and `skipTrailingSlashRedirect` to handle advanced use cases.\n\n`skipTrailingSlashRedirect` disables Next.js redirects for adding or removing trailing slashes. This allows custom handling inside proxy to maintain the trailing slash for some paths but not others, which can make incremental migrations easier.\n\n```js filename=\"next.config.js\"\nmodule.exports = {\n  skipTrailingSlashRedirect: true,\n}\n```\n\n```js filename=\"proxy.js\"\nconst legacyPrefixes = ['/docs', '/blog']\n\nexport default async function proxy(req) {\n  const { pathname } = req.nextUrl\n\n  if (legacyPrefixes.some((prefix) => pathname.startsWith(prefix))) {\n    return NextResponse.next()\n  }\n\n  // apply trailing slash handling\n  if (\n    !pathname.endsWith('/') &&\n    !pathname.match(/((?!\\.well-known(?:\\/.*)?)(?:[^/]+\\/)*[^/]+\\.\\w+)/)\n  ) {\n    return NextResponse.redirect(\n      new URL(`${req.nextUrl.pathname}/`, req.nextUrl)\n    )\n  }\n}\n```\n\n`skipProxyUrlNormalize` allows for disabling the URL normalization in Next.js to make handling direct visits and client-transitions the same. In some advanced cases, this option provides full control by using the original URL.\n\n```js filename=\"next.config.js\"\nmodule.exports = {\n  skipProxyUrlNormalize: true,\n}\n```\n\n```js filename=\"proxy.js\"\nexport default async function proxy(req) {\n  const { pathname } = req.nextUrl\n\n  // GET /_next/data/build-id/hello.json\n\n  console.log(pathname)\n  // with the flag this now /_next/data/build-id/hello.json\n  // without the flag this would be normalized to /hello\n}\n```\n\n## Examples\n\n### Conditional Statements\n\n```ts filename=\"proxy.ts\" switcher\nimport { NextResponse } from 'next/server'\nimport type { NextRequest } from 'next/server'\n\nexport function proxy(request: NextRequest) {\n  if (request.nextUrl.pathname.startsWith('/about')) {\n    return NextResponse.rewrite(new URL('/about-2', request.url))\n  }\n\n  if (request.nextUrl.pathname.startsWith('/dashboard')) {\n    return NextResponse.rewrite(new URL('/dashboard/user', request.url))\n  }\n}\n```\n\n```js filename=\"proxy.js\" switcher\nimport { NextResponse } from 'next/server'\n\nexport function proxy(request) {\n  if (request.nextUrl.pathname.startsWith('/about')) {\n    return NextResponse.rewrite(new URL('/about-2', request.url))\n  }\n\n  if (request.nextUrl.pathname.startsWith('/dashboard')) {\n    return NextResponse.rewrite(new URL('/dashboard/user', request.url))\n  }\n}\n```\n\n### Using Cookies\n\nCookies are regular headers. On a `Request`, they are stored in the `Cookie` header. On a `Response` they are in the `Set-Cookie` header. Next.js provides a convenient way to access and manipulate these cookies through the `cookies` extension on `NextRequest` and `NextResponse`.\n\n1. For incoming requests, `cookies` comes with the following methods: `get`, `getAll`, `set`, and `delete` cookies. You can check for the existence of a cookie with `has` or remove all cookies with `clear`.\n2. For outgoing responses, `cookies` have the following methods `get`, `getAll`, `set`, and `delete`.\n\n```ts filename=\"proxy.ts\" switcher\nimport { NextResponse } from 'next/server'\nimport type { NextRequest } from 'next/server'\n\nexport function proxy(request: NextRequest) {\n  // Assume a \"Cookie:nextjs=fast\" header to be present on the incoming request\n  // Getting cookies from the request using the `RequestCookies` API\n  let cookie = request.cookies.get('nextjs')\n  console.log(cookie) // => { name: 'nextjs', value: 'fast', Path: '/' }\n  const allCookies = request.cookies.getAll()\n  console.log(allCookies) // => [{ name: 'nextjs', value: 'fast' }]\n\n  request.cookies.has('nextjs') // => true\n  request.cookies.delete('nextjs')\n  request.cookies.has('nextjs') // => false\n\n  // Setting cookies on the response using the `ResponseCookies` API\n  const response = NextResponse.next()\n  response.cookies.set('vercel', 'fast')\n  response.cookies.set({\n    name: 'vercel',\n    value: 'fast',\n    path: '/',\n  })\n  cookie = response.cookies.get('vercel')\n  console.log(cookie) // => { name: 'vercel', value: 'fast', Path: '/' }\n  // The outgoing response will have a `Set-Cookie:vercel=fast;path=/` header.\n\n  return response\n}\n```\n\n```js filename=\"proxy.js\" switcher\nimport { NextResponse } from 'next/server'\n\nexport function proxy(request) {\n  // Assume a \"Cookie:nextjs=fast\" header to be present on the incoming request\n  // Getting cookies from the request using the `RequestCookies` API\n  let cookie = request.cookies.get('nextjs')\n  console.log(cookie) // => { name: 'nextjs', value: 'fast', Path: '/' }\n  const allCookies = request.cookies.getAll()\n  console.log(allCookies) // => [{ name: 'nextjs', value: 'fast' }]\n\n  request.cookies.has('nextjs') // => true\n  request.cookies.delete('nextjs')\n  request.cookies.has('nextjs') // => false\n\n  // Setting cookies on the response using the `ResponseCookies` API\n  const response = NextResponse.next()\n  response.cookies.set('vercel', 'fast')\n  response.cookies.set({\n    name: 'vercel',\n    value: 'fast',\n    path: '/',\n  })\n  cookie = response.cookies.get('vercel')\n  console.log(cookie) // => { name: 'vercel', value: 'fast', Path: '/' }\n  // The outgoing response will have a `Set-Cookie:vercel=fast;path=/` header.\n\n  return response\n}\n```\n\n### Setting Headers\n\nYou can set request and response headers using the `NextResponse` API (setting *request* headers is available since Next.js v13.0.0).\n\n```ts filename=\"proxy.ts\" switcher\nimport { NextResponse } from 'next/server'\nimport type { NextRequest } from 'next/server'\n\nexport function proxy(request: NextRequest) {\n  // Clone the request headers and set a new header `x-hello-from-proxy1`\n  const requestHeaders = new Headers(request.headers)\n  requestHeaders.set('x-hello-from-proxy1', 'hello')\n\n  // You can also set request headers in NextResponse.next\n  const response = NextResponse.next({\n    request: {\n      // New request headers\n      headers: requestHeaders,\n    },\n  })\n\n  // Set a new response header `x-hello-from-proxy2`\n  response.headers.set('x-hello-from-proxy2', 'hello')\n  return response\n}\n```\n\n```js filename=\"proxy.js\" switcher\nimport { NextResponse } from 'next/server'\n\nexport function proxy(request) {\n  // Clone the request headers and set a new header `x-hello-from-proxy1`\n  const requestHeaders = new Headers(request.headers)\n  requestHeaders.set('x-hello-from-proxy1', 'hello')\n\n  // You can also set request headers in NextResponse.next\n  const response = NextResponse.next({\n    request: {\n      // New request headers\n      headers: requestHeaders,\n    },\n  })\n\n  // Set a new response header `x-hello-from-proxy2`\n  response.headers.set('x-hello-from-proxy2', 'hello')\n  return response\n}\n```\n\nNote that the snippet uses:\n\n* `NextResponse.next({ request: { headers: requestHeaders } })` to make `requestHeaders` available upstream\n* **NOT** `NextResponse.next({ headers: requestHeaders })` which makes `requestHeaders` available to clients\n\nLearn more in [NextResponse headers in Proxy](/docs/app/api-reference/functions/next-response#next).\n\n> **Good to know**: Avoid setting large headers as it might cause [431 Request Header Fields Too Large](https://developer.mozilla.org/docs/Web/HTTP/Status/431) error depending on your backend web server configuration.\n\n#### RSC requests and rewrites\n\nDuring RSC requests, Next.js strips internal Flight headers from the `request` instance in Proxy. For example, headers like `rsc`, `next-router-state-tree`, and `next-router-prefetch` are not exposed through `request.headers`. This is to prevent accidentally handling an RSC request differently than the HTML request as both need to align.\n\nWhen you use `NextResponse.rewrite()`, Next.js automatically propagates the required RSC rewrite headers upstream.\n\nIf you implement custom rewrite logic with `fetch()` instead of `NextResponse.rewrite()`, you can run into missing RSC headers unless you forward them manually.\n\nFor custom `fetch` rewrite setups, you can also enable `skipProxyUrlNormalize` in `next.config.js` so your rewrite logic can receive the necessary URL shape and RSC headers from the provided request object:\n\n```js filename=\"next.config.js\"\nmodule.exports = {\n  skipProxyUrlNormalize: true,\n}\n```\n\n### CORS\n\nYou can set CORS headers in Proxy to allow cross-origin requests, including [simple](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#simple_requests) and [preflighted](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#preflighted_requests) requests.\n\n```tsx filename=\"proxy.ts\" switcher\nimport { NextResponse } from 'next/server'\nimport type { NextRequest } from 'next/server'\n\nconst allowedOrigins = ['https://acme.com', 'https://my-app.org']\n\nconst corsOptions = {\n  'Access-Control-Allow-Methods': 'GET, POST, PUT, DELETE, OPTIONS',\n  'Access-Control-Allow-Headers': 'Content-Type, Authorization',\n}\n\nexport function proxy(request: NextRequest) {\n  // Check the origin from the request\n  const origin = request.headers.get('origin') ?? ''\n  const isAllowedOrigin = allowedOrigins.includes(origin)\n\n  // Handle preflighted requests\n  const isPreflight = request.method === 'OPTIONS'\n\n  if (isPreflight) {\n    const preflightHeaders = {\n      ...(isAllowedOrigin && { 'Access-Control-Allow-Origin': origin }),\n      ...corsOptions,\n    }\n    return NextResponse.json({}, { headers: preflightHeaders })\n  }\n\n  // Handle simple requests\n  const response = NextResponse.next()\n\n  if (isAllowedOrigin) {\n    response.headers.set('Access-Control-Allow-Origin', origin)\n  }\n\n  Object.entries(corsOptions).forEach(([key, value]) => {\n    response.headers.set(key, value)\n  })\n\n  return response\n}\n\nexport const config = {\n  matcher: '/api/:path*',\n}\n```\n\n```jsx filename=\"proxy.js\" switcher\nimport { NextResponse } from 'next/server'\n\nconst allowedOrigins = ['https://acme.com', 'https://my-app.org']\n\nconst corsOptions = {\n  'Access-Control-Allow-Methods': 'GET, POST, PUT, DELETE, OPTIONS',\n  'Access-Control-Allow-Headers': 'Content-Type, Authorization',\n}\n\nexport function proxy(request) {\n  // Check the origin from the request\n  const origin = request.headers.get('origin') ?? ''\n  const isAllowedOrigin = allowedOrigins.includes(origin)\n\n  // Handle preflighted requests\n  const isPreflight = request.method === 'OPTIONS'\n\n  if (isPreflight) {\n    const preflightHeaders = {\n      ...(isAllowedOrigin && { 'Access-Control-Allow-Origin': origin }),\n      ...corsOptions,\n    }\n    return NextResponse.json({}, { headers: preflightHeaders })\n  }\n\n  // Handle simple requests\n  const response = NextResponse.next()\n\n  if (isAllowedOrigin) {\n    response.headers.set('Access-Control-Allow-Origin', origin)\n  }\n\n  Object.entries(corsOptions).forEach(([key, value]) => {\n    response.headers.set(key, value)\n  })\n\n  return response\n}\n\nexport const config = {\n  matcher: '/api/:path*',\n}\n```\n\n> **Good to know:** You can configure CORS headers for individual routes in [Route Handlers](/docs/app/api-reference/file-conventions/route#cors).\n\n### Producing a response\n\nYou can respond from Proxy directly by returning a `Response` or `NextResponse` instance. (This is available since [Next.js v13.1.0](https://nextjs.org/blog/next-13-1#nextjs-advanced-proxy))\n\n```ts filename=\"proxy.ts\" switcher\nimport type { NextRequest } from 'next/server'\nimport { isAuthenticated } from '@lib/auth'\n\n// Limit the proxy to paths starting with `/api/`\nexport const config = {\n  matcher: '/api/:function*',\n}\n\nexport function proxy(request: NextRequest) {\n  // Call our authentication function to check the request\n  if (!isAuthenticated(request)) {\n    // Respond with JSON indicating an error message\n    return Response.json(\n      { success: false, message: 'authentication failed' },\n      { status: 401 }\n    )\n  }\n}\n```\n\n```js filename=\"proxy.js\" switcher\nimport { isAuthenticated } from '@lib/auth'\n\n// Limit the proxy to paths starting with `/api/`\nexport const config = {\n  matcher: '/api/:function*',\n}\n\nexport function proxy(request) {\n  // Call our authentication function to check the request\n  if (!isAuthenticated(request)) {\n    // Respond with JSON indicating an error message\n    return Response.json(\n      { success: false, message: 'authentication failed' },\n      { status: 401 }\n    )\n  }\n}\n```\n\n### Negative matching\n\nThe `matcher` config allows full regex so matching like negative lookaheads or character matching is supported. An example of a negative lookahead to match all except specific paths can be seen here:\n\n```js filename=\"proxy.js\"\nexport const config = {\n  matcher: [\n    /*\n     * Match all request paths except for the ones starting with:\n     * - api (API routes)\n     * - _next/static (static files)\n     * - _next/image (image optimization files)\n     * - favicon.ico, sitemap.xml, robots.txt (metadata files)\n     */\n    '/((?!api|_next/static|_next/image|favicon.ico|sitemap.xml|robots.txt).*)',\n  ],\n}\n```\n\nYou can also bypass Proxy for certain requests by using the `missing` or `has` arrays, or a combination of both:\n\n```js filename=\"proxy.js\"\nexport const config = {\n  matcher: [\n    /*\n     * Match all request paths except for the ones starting with:\n     * - api (API routes)\n     * - _next/static (static files)\n     * - _next/image (image optimization files)\n     * - favicon.ico, sitemap.xml, robots.txt (metadata files)\n     */\n    {\n      source:\n        '/((?!api|_next/static|_next/image|favicon.ico|sitemap.xml|robots.txt).*)',\n      missing: [\n        { type: 'header', key: 'next-router-prefetch' },\n        { type: 'header', key: 'purpose', value: 'prefetch' },\n      ],\n    },\n\n    {\n      source:\n        '/((?!api|_next/static|_next/image|favicon.ico|sitemap.xml|robots.txt).*)',\n      has: [\n        { type: 'header', key: 'next-router-prefetch' },\n        { type: 'header', key: 'purpose', value: 'prefetch' },\n      ],\n    },\n\n    {\n      source:\n        '/((?!api|_next/static|_next/image|favicon.ico|sitemap.xml|robots.txt).*)',\n      has: [{ type: 'header', key: 'x-present' }],\n      missing: [{ type: 'header', key: 'x-missing', value: 'prefetch' }],\n    },\n  ],\n}\n```\n\n> **Good to know**:\n>\n> Even when `_next/data` is excluded in a negative matcher pattern, proxy will still be invoked for `_next/data` routes. This is intentional behavior to prevent accidental security issues where you might protect a page but forget to protect the corresponding data route.\n\n```js filename=\"proxy.js\"\nexport const config = {\n  matcher:\n    '/((?!api|_next/data|_next/static|_next/image|favicon.ico|sitemap.xml|robots.txt).*)',\n}\n\n// Proxy will still run for /_next/data/* routes despite being excluded\n```\n\n### `waitUntil` and `NextFetchEvent`\n\nThe `NextFetchEvent` object extends the native [`FetchEvent`](https://developer.mozilla.org/docs/Web/API/FetchEvent) object, and includes the [`waitUntil()`](https://developer.mozilla.org/docs/Web/API/ExtendableEvent/waitUntil) method.\n\nThe `waitUntil()` method takes a promise as an argument, and extends the lifetime of the Proxy until the promise settles. This is useful for performing work in the background.\n\n```ts filename=\"proxy.ts\"\nimport { NextResponse } from 'next/server'\nimport type { NextFetchEvent, NextRequest } from 'next/server'\n\nexport function proxy(req: NextRequest, event: NextFetchEvent) {\n  event.waitUntil(\n    fetch('https://my-analytics-platform.com', {\n      method: 'POST',\n      body: JSON.stringify({ pathname: req.nextUrl.pathname }),\n    })\n  )\n\n  return NextResponse.next()\n}\n```\n\n### Unit testing (experimental)\n\nStarting in Next.js 15.1, the `next/experimental/testing/server` package contains utilities to help unit test proxy files. Unit testing proxy can help ensure that it's only run on desired paths and that custom routing logic works as intended before code reaches production.\n\nThe `unstable_doesProxyMatch` function can be used to assert whether proxy will run for the provided URL, headers, and cookies.\n\n```js\nimport { unstable_doesProxyMatch } from 'next/experimental/testing/server'\n\nexpect(\n  unstable_doesProxyMatch({\n    config,\n    nextConfig,\n    url: '/test',\n  })\n).toEqual(false)\n```\n\nThe entire proxy function can also be tested.\n\n```js\nimport { isRewrite, getRewrittenUrl } from 'next/experimental/testing/server'\n\nconst request = new NextRequest('https://nextjs.org/docs')\nconst response = await proxy(request)\nexpect(isRewrite(response)).toEqual(true)\nexpect(getRewrittenUrl(response)).toEqual('https://other-domain.com/docs')\n// getRedirectUrl could also be used if the response were a redirect\n```\n\n## Platform support\n\n| Deployment Option                                                   | Supported         |\n| ------------------------------------------------------------------- | ----------------- |\n| [Node.js server](/docs/app/getting-started/deploying#nodejs-server) | Yes               |\n| [Docker container](/docs/app/getting-started/deploying#docker)      | Yes               |\n| [Static export](/docs/app/getting-started/deploying#static-export)  | No                |\n| [Adapters](/docs/app/getting-started/deploying#adapters)            | Platform-specific |\n\nLearn how to [configure Proxy](/docs/app/guides/self-hosting#proxy) when self-hosting Next.js.\n\n## Migration to Proxy\n\n### Why the Change\n\nThe reason behind the renaming of `middleware` is that the term \"middleware\" can often be confused with Express.js middleware, leading to a misinterpretation of its purpose. Also, Middleware is highly capable, so it may encourage the usage; however, this feature is recommended to be used as a last resort.\n\nNext.js is moving forward to provide better APIs with better ergonomics so that developers can achieve their goals without Middleware. This is the reason behind the renaming of `middleware`.\n\n### Why \"Proxy\"\n\nThe name Proxy clarifies what Middleware is capable of. The term \"proxy\" implies a network boundary in front of the app, which is how this feature behaves. It can run outside of your application’s main runtime and handle requests before they reach your app. These characteristics align better with the term \"proxy\" and provide a clearer purpose for the feature.\n\n### How to Migrate\n\nWe recommend users avoid relying on Middleware unless no other options exist. Our goal is to give them APIs with better ergonomics so they can achieve their goals without Middleware.\n\nThe term “middleware” often confuses users with Express.js middleware, which can encourage misuse. To clarify our direction, we are renaming the file convention to “proxy.” This highlights that we are moving away from Middleware, breaking down its overloaded features, and making the Proxy clear in its purpose.\n\nNext.js provides a codemod to migrate from `middleware.ts` to `proxy.ts`. You can run the following command to migrate:\n\n```bash\nnpx @next/codemod@canary middleware-to-proxy .\n```\n\nThe codemod will rename the file and the function name from `middleware` to `proxy`.\n\n```diff\n// middleware.ts -> proxy.ts\n\n- export function middleware() {\n+ export function proxy() {\n```\n\n## Version history\n\n| Version   | Changes                                                                                       |\n| --------- | --------------------------------------------------------------------------------------------- |\n| `v16.0.0` | Middleware is deprecated and renamed to Proxy.

See [Migration to Proxy](#migration-to-proxy) for more details.\n\nThe `proxy.js|ts` file is used to write [Proxy](/docs/app/getting-started/proxy) and run code on the server before a request is completed. Then, based on the incoming request, you can modify the response by rewriting, redirecting, modifying the request or response headers, or responding directly.\n\nProxy executes before routes are rendered. It's particularly useful for implementing custom server-side logic like authentication, logging, or handling redirects.\n\n> **Good to know**:\n>\n> Proxy is meant to be invoked separately of your render code and in optimized cases deployed to your CDN for fast redirect/rewrite handling, you should not attempt relying on shared modules or globals.\n>\n> To pass information from Proxy to your application, use [headers](#setting-headers), [cookies](#using-cookies), [rewrites](/docs/app/api-reference/functions/next-response#rewrite), [redirects](/docs/app/api-reference/functions/next-response#redirect), or the URL.\n\nCreate a `proxy.ts` (or `.js`) file in the project root, or inside `src` if applicable, so that it is located at the same level as `pages` or `app`.\n\nIf you’ve customized [`pageExtensions`](/docs/app/api-reference/config/next-config-js/pageExtensions), for example to `.page.ts` or `.page.js`, name your file `proxy.page.ts` or `proxy.page.js` accordingly.\n\n```tsx filename=\"proxy.ts\" switcher\nimport { NextResponse } from 'next/server'\nimport type { NextRequest } from 'next/server'\n\n// This function can be marked `async` if using `await` inside\nexport function proxy(request: NextRequest) {\n  return NextResponse.redirect(new URL('/home', request.url))\n}\n\nexport const config = {\n  matcher: '/about/:path*',\n}\n```\n\n```js filename=\"proxy.js\" switcher\nimport { NextResponse } from 'next/server'\n\n// This function can be marked `async` if using `await` inside\nexport function proxy(request) {\n  return NextResponse.redirect(new URL('/home', request.url))\n}\n\nexport const config = {\n  matcher: '/about/:path*',\n}\n```\n\n## Exports\n\n### Proxy function\n\nThe file must export a single function, either as a default export or named `proxy`. Note that multiple proxy from the same file are not supported.\n\n```js filename=\"proxy.js\"\n// Example of default export\nexport default function proxy(request) {\n  // Proxy logic\n}\n```\n\n### Config object (optional)\n\nOptionally, a config object can be exported alongside the Proxy function. This object includes the [matcher](#matcher) to specify paths where the Proxy applies.\n\n### Matcher\n\nThe `matcher` option allows you to target specific paths for the Proxy to run on.\n\nWithout a `matcher`, Proxy runs on **every request**, including static files (`_next/static`), image optimizations (`_next/image`), and assets in the `public/` folder. Consider using a [negative match pattern](#negative-matching) to exclude these paths, otherwise auth logic or redirects can unintentionally block CSS, JS, or images from loading.\n\nYou can specify paths in several ways:\n\n* For a single path: Directly use a string to define the path, like `'/about'`.\n* For multiple paths: Use an array to list multiple paths, such as `matcher: ['/about', '/contact']`, which applies the Proxy to both `/about` and `/contact`.\n\n```js filename=\"proxy.js\"\nexport const config = {\n  matcher: ['/about/:path*', '/dashboard/:path*'],\n}\n```\n\nAdditionally, the `matcher` option supports complex path specifications using regular expressions. For example, you can exclude certain paths with a regular expression matcher:\n\n```js filename=\"proxy.js\"\nexport const config = {\n  matcher: [\n    // Exclude API routes, static files, image optimizations, and .png files\n    '/((?!api|_next/static|_next/image|.*\\\\.png$).*)',\n  ],\n}\n```\n\nThis enables precise control over which paths to include or exclude.\n\nThe `matcher` option accepts an array of objects with the following keys:\n\n* `source`: The path or pattern used to match the request paths. It can be a string for direct path matching or a pattern for more complex matching.\n* `locale` (optional): A boolean that, when set to `false`, ignores locale-based routing in path matching.\n* `has` (optional): Specifies conditions based on the presence of specific request elements such as headers, query parameters, or cookies.\n* `missing` (optional): Focuses on conditions where certain request elements are absent, like missing headers or cookies.\n\n```js filename=\"proxy.js\"\nexport const config = {\n  matcher: [\n    {\n      source: '/api/:path*',\n      locale: false,\n      has: [\n        { type: 'header', key: 'Authorization', value: 'Bearer Token' },\n        { type: 'query', key: 'userId', value: '123' },\n      ],\n      missing: [{ type: 'cookie', key: 'session', value: 'active' }],\n    },\n  ],\n}\n```\n\nThe `source` path patterns:\n\n1. MUST start with `/`\n2. Can include named parameters: `/about/:path` matches `/about/a` and `/about/b` but not `/about/a/c`\n3. Can have modifiers on named parameters (starting with `:`): `/about/:path*` matches `/about/a/b/c` because `*` is *zero or more*. `?` is *zero or one* and `+` *one or more*\n4. Can use regular expression enclosed in parenthesis: `/about/(.*)` is the same as `/about/:path*`\n5. Are anchored to the start of the path: `/about` matches `/about` and `/about/team` but not `/blog/about`\n\nRead more details on [path-to-regexp](https://github.com/pillarjs/path-to-regexp#path-to-regexp-1) documentation.\n\n> **Good to know**:\n>\n> * The `matcher` values need to be constants so they can be statically analyzed at build-time. Dynamic values such as variables will be ignored.\n> * For backward compatibility, Next.js always considers `/public` as `/public/index`. Therefore, a matcher of `/public/:path` will match.\n\n## Params\n\n### `request`\n\nWhen defining Proxy, the default export function accepts a single parameter, `request`. This parameter is an instance of `NextRequest`, which represents the incoming HTTP request.\n\n```tsx filename=\"proxy.ts\" switcher\nimport type { NextRequest } from 'next/server'\n\nexport function proxy(request: NextRequest) {\n  // Proxy logic goes here\n}\n```\n\n```js filename=\"proxy.js\" switcher\nexport function proxy(request) {\n  // Proxy logic goes here\n}\n```\n\nIf you prefer a shorthand, you can use the `NextProxy` type. It infers the parameter types for both `request` (`NextRequest`) and `event` (`NextFetchEvent`) automatically:\n\n```tsx filename=\"proxy.ts\"\nimport type { NextProxy } from 'next/server'\n\nexport const proxy: NextProxy = (request, event) => {\n  event.waitUntil(Promise.resolve())\n  return Response.json({ pathname: request.nextUrl.pathname })\n}\n```\n\n> **Good to know**:\n>\n> * `NextRequest` is a type that represents incoming HTTP requests in Next.js Proxy, whereas [`NextResponse`](#nextresponse) is a class used to manipulate and send back HTTP responses.\n\n## NextResponse\n\nThe `NextResponse` API allows you to:\n\n* `redirect` the incoming request to a different URL\n* `rewrite` the response by displaying a given URL\n* Set request headers for API Routes, `getServerSideProps`, and `rewrite` destinations\n* Set response cookies\n* Set response headers\n\nTo produce a response from Proxy, you can:\n\n1. `rewrite` to a route ([Page](/docs/app/api-reference/file-conventions/page) or [Route Handler](/docs/app/api-reference/file-conventions/route)) that produces a response\n2. return a `NextResponse` directly. See [Producing a Response](#producing-a-response)\n\n> **Good to know**: For redirects, you can also use `Response.redirect` instead of `NextResponse.redirect`.\n\n## Execution order\n\nProxy will be invoked for **every route in your project**. Given this, it's crucial to use [matchers](#matcher) to precisely target or exclude specific routes. The following is the execution order:\n\n1. `headers` from `next.config.js`\n2. `redirects` from `next.config.js`\n3. Proxy (`rewrites`, `redirects`, etc.)\n4. `beforeFiles` (`rewrites`) from `next.config.js`\n5. Filesystem routes (`public/`, `_next/static/`, `pages/`, `app/`, etc.)\n6. `afterFiles` (`rewrites`) from `next.config.js`\n7. Dynamic Routes (`/blog/[slug]`)\n8. `fallback` (`rewrites`) from `next.config.js`\n\n> **Good to know:** [Server Functions](/docs/app/api-reference/directives/use-server) are not separate routes in this chain. They are handled as POST requests to the route where they are used, so a Proxy matcher that excludes a path will also skip Server Function calls on that path.\n>\n> A matcher change or a refactor that moves a Server Function to a different route can silently remove Proxy coverage. Always verify authentication and authorization inside each Server Function rather than relying on Proxy alone. See the [Data Security guide](/docs/app/guides/data-security#authentication-and-authorization) for recommended patterns.\n\n## Runtime\n\nProxy defaults to using the Node.js runtime. The [`runtime`](/docs/app/api-reference/file-conventions/route-segment-config/runtime) config option is not available in Proxy files. Setting the `runtime` config option in Proxy will throw an error.\n\n## Advanced Proxy flags\n\nIn `v13.1` of Next.js two additional flags were introduced for proxy, `skipProxyUrlNormalize` (formerly `skipMiddlewareUrlNormalize`) and `skipTrailingSlashRedirect` to handle advanced use cases.\n\n`skipTrailingSlashRedirect` disables Next.js redirects for adding or removing trailing slashes. This allows custom handling inside proxy to maintain the trailing slash for some paths but not others, which can make incremental migrations easier.\n\n```js filename=\"next.config.js\"\nmodule.exports = {\n  skipTrailingSlashRedirect: true,\n}\n```\n\n```js filename=\"proxy.js\"\nconst legacyPrefixes = ['/docs', '/blog']\n\nexport default async function proxy(req) {\n  const { pathname } = req.nextUrl\n\n  if (legacyPrefixes.some((prefix) => pathname.startsWith(prefix))) {\n    return NextResponse.next()\n  }\n\n  // apply trailing slash handling\n  if (\n    !pathname.endsWith('/') &&\n    !pathname.match(/((?!\\.well-known(?:\\/.*)?)(?:[^/]+\\/)*[^/]+\\.\\w+)/)\n  ) {\n    return NextResponse.redirect(\n      new URL(`${req.nextUrl.pathname}/`, req.nextUrl)\n    )\n  }\n}\n```\n\n`skipProxyUrlNormalize` allows for disabling the URL normalization in Next.js to make handling direct visits and client-transitions the same. In some advanced cases, this option provides full control by using the original URL.\n\n```js filename=\"next.config.js\"\nmodule.exports = {\n  skipProxyUrlNormalize: true,\n}\n```\n\n```js filename=\"proxy.js\"\nexport default async function proxy(req) {\n  const { pathname } = req.nextUrl\n\n  // GET /_next/data/build-id/hello.json\n\n  console.log(pathname)\n  // with the flag this now /_next/data/build-id/hello.json\n  // without the flag this would be normalized to /hello\n}\n```\n\n## Examples\n\n### Conditional Statements\n\n```ts filename=\"proxy.ts\" switcher\nimport { NextResponse } from 'next/server'\nimport type { NextRequest } from 'next/server'\n\nexport function proxy(request: NextRequest) {\n  if (request.nextUrl.pathname.startsWith('/about')) {\n    return NextResponse.rewrite(new URL('/about-2', request.url))\n  }\n\n  if (request.nextUrl.pathname.startsWith('/dashboard')) {\n    return NextResponse.rewrite(new URL('/dashboard/user', request.url))\n  }\n}\n```\n\n```js filename=\"proxy.js\" switcher\nimport { NextResponse } from 'next/server'\n\nexport function proxy(request) {\n  if (request.nextUrl.pathname.startsWith('/about')) {\n    return NextResponse.rewrite(new URL('/about-2', request.url))\n  }\n\n  if (request.nextUrl.pathname.startsWith('/dashboard')) {\n    return NextResponse.rewrite(new URL('/dashboard/user', request.url))\n  }\n}\n```\n\n### Using Cookies\n\nCookies are regular headers. On a `Request`, they are stored in the `Cookie` header. On a `Response` they are in the `Set-Cookie` header. Next.js provides a convenient way to access and manipulate these cookies through the `cookies` extension on `NextRequest` and `NextResponse`.\n\n1. For incoming requests, `cookies` comes with the following methods: `get`, `getAll`, `set`, and `delete` cookies. You can check for the existence of a cookie with `has` or remove all cookies with `clear`.\n2. For outgoing responses, `cookies` have the following methods `get`, `getAll`, `set`, and `delete`.\n\n```ts filename=\"proxy.ts\" switcher\nimport { NextResponse } from 'next/server'\nimport type { NextRequest } from 'next/server'\n\nexport function proxy(request: NextRequest) {\n  // Assume a \"Cookie:nextjs=fast\" header to be present on the incoming request\n  // Getting cookies from the request using the `RequestCookies` API\n  let cookie = request.cookies.get('nextjs')\n  console.log(cookie) // => { name: 'nextjs', value: 'fast', Path: '/' }\n  const allCookies = request.cookies.getAll()\n  console.log(allCookies) // => [{ name: 'nextjs', value: 'fast' }]\n\n  request.cookies.has('nextjs') // => true\n  request.cookies.delete('nextjs')\n  request.cookies.has('nextjs') // => false\n\n  // Setting cookies on the response using the `ResponseCookies` API\n  const response = NextResponse.next()\n  response.cookies.set('vercel', 'fast')\n  response.cookies.set({\n    name: 'vercel',\n    value: 'fast',\n    path: '/',\n  })\n  cookie = response.cookies.get('vercel')\n  console.log(cookie) // => { name: 'vercel', value: 'fast', Path: '/' }\n  // The outgoing response will have a `Set-Cookie:vercel=fast;path=/` header.\n\n  return response\n}\n```\n\n```js filename=\"proxy.js\" switcher\nimport { NextResponse } from 'next/server'\n\nexport function proxy(request) {\n  // Assume a \"Cookie:nextjs=fast\" header to be present on the incoming request\n  // Getting cookies from the request using the `RequestCookies` API\n  let cookie = request.cookies.get('nextjs')\n  console.log(cookie) // => { name: 'nextjs', value: 'fast', Path: '/' }\n  const allCookies = request.cookies.getAll()\n  console.log(allCookies) // => [{ name: 'nextjs', value: 'fast' }]\n\n  request.cookies.has('nextjs') // => true\n  request.cookies.delete('nextjs')\n  request.cookies.has('nextjs') // => false\n\n  // Setting cookies on the response using the `ResponseCookies` API\n  const response = NextResponse.next()\n  response.cookies.set('vercel', 'fast')\n  response.cookies.set({\n    name: 'vercel',\n    value: 'fast',\n    path: '/',\n  })\n  cookie = response.cookies.get('vercel')\n  console.log(cookie) // => { name: 'vercel', value: 'fast', Path: '/' }\n  // The outgoing response will have a `Set-Cookie:vercel=fast;path=/` header.\n\n  return response\n}\n```\n\n### Setting Headers\n\nYou can set request and response headers using the `NextResponse` API (setting *request* headers is available since Next.js v13.0.0).\n\n```ts filename=\"proxy.ts\" switcher\nimport { NextResponse } from 'next/server'\nimport type { NextRequest } from 'next/server'\n\nexport function proxy(request: NextRequest) {\n  // Clone the request headers and set a new header `x-hello-from-proxy1`\n  const requestHeaders = new Headers(request.headers)\n  requestHeaders.set('x-hello-from-proxy1', 'hello')\n\n  // You can also set request headers in NextResponse.next\n  const response = NextResponse.next({\n    request: {\n      // New request headers\n      headers: requestHeaders,\n    },\n  })\n\n  // Set a new response header `x-hello-from-proxy2`\n  response.headers.set('x-hello-from-proxy2', 'hello')\n  return response\n}\n```\n\n```js filename=\"proxy.js\" switcher\nimport { NextResponse } from 'next/server'\n\nexport function proxy(request) {\n  // Clone the request headers and set a new header `x-hello-from-proxy1`\n  const requestHeaders = new Headers(request.headers)\n  requestHeaders.set('x-hello-from-proxy1', 'hello')\n\n  // You can also set request headers in NextResponse.next\n  const response = NextResponse.next({\n    request: {\n      // New request headers\n      headers: requestHeaders,\n    },\n  })\n\n  // Set a new response header `x-hello-from-proxy2`\n  response.headers.set('x-hello-from-proxy2', 'hello')\n  return response\n}\n```\n\nNote that the snippet uses:\n\n* `NextResponse.next({ request: { headers: requestHeaders } })` to make `requestHeaders` available upstream\n* **NOT** `NextResponse.next({ headers: requestHeaders })` which makes `requestHeaders` available to clients\n\nLearn more in [NextResponse headers in Proxy](/docs/app/api-reference/functions/next-response#next).\n\n> **Good to know**: Avoid setting large headers as it might cause [431 Request Header Fields Too Large](https://developer.mozilla.org/docs/Web/HTTP/Status/431) error depending on your backend web server configuration.\n\n#### RSC requests and rewrites\n\nDuring RSC requests, Next.js strips internal Flight headers from the `request` instance in Proxy. For example, headers like `rsc`, `next-router-state-tree`, and `next-router-prefetch` are not exposed through `request.headers`. This is to prevent accidentally handling an RSC request differently than the HTML request as both need to align.\n\nWhen you use `NextResponse.rewrite()`, Next.js automatically propagates the required RSC rewrite headers upstream.\n\nIf you implement custom rewrite logic with `fetch()` instead of `NextResponse.rewrite()`, you can run into missing RSC headers unless you forward them manually.\n\nFor custom `fetch` rewrite setups, you can also enable `skipProxyUrlNormalize` in `next.config.js` so your rewrite logic can receive the necessary URL shape and RSC headers from the provided request object:\n\n```js filename=\"next.config.js\"\nmodule.exports = {\n  skipProxyUrlNormalize: true,\n}\n```\n\n### CORS\n\nYou can set CORS headers in Proxy to allow cross-origin requests, including [simple](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#simple_requests) and [preflighted](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#preflighted_requests) requests.\n\n```tsx filename=\"proxy.ts\" switcher\nimport { NextResponse } from 'next/server'\nimport type { NextRequest } from 'next/server'\n\nconst allowedOrigins = ['https://acme.com', 'https://my-app.org']\n\nconst corsOptions = {\n  'Access-Control-Allow-Methods': 'GET, POST, PUT, DELETE, OPTIONS',\n  'Access-Control-Allow-Headers': 'Content-Type, Authorization',\n}\n\nexport function proxy(request: NextRequest) {\n  // Check the origin from the request\n  const origin = request.headers.get('origin') ?? ''\n  const isAllowedOrigin = allowedOrigins.includes(origin)\n\n  // Handle preflighted requests\n  const isPreflight = request.method === 'OPTIONS'\n\n  if (isPreflight) {\n    const preflightHeaders = {\n      ...(isAllowedOrigin && { 'Access-Control-Allow-Origin': origin }),\n      ...corsOptions,\n    }\n    return NextResponse.json({}, { headers: preflightHeaders })\n  }\n\n  // Handle simple requests\n  const response = NextResponse.next()\n\n  if (isAllowedOrigin) {\n    response.headers.set('Access-Control-Allow-Origin', origin)\n  }\n\n  Object.entries(corsOptions).forEach(([key, value]) => {\n    response.headers.set(key, value)\n  })\n\n  return response\n}\n\nexport const config = {\n  matcher: '/api/:path*',\n}\n```\n\n```jsx filename=\"proxy.js\" switcher\nimport { NextResponse } from 'next/server'\n\nconst allowedOrigins = ['https://acme.com', 'https://my-app.org']\n\nconst corsOptions = {\n  'Access-Control-Allow-Methods': 'GET, POST, PUT, DELETE, OPTIONS',\n  'Access-Control-Allow-Headers': 'Content-Type, Authorization',\n}\n\nexport function proxy(request) {\n  // Check the origin from the request\n  const origin = request.headers.get('origin') ?? ''\n  const isAllowedOrigin = allowedOrigins.includes(origin)\n\n  // Handle preflighted requests\n  const isPreflight = request.method === 'OPTIONS'\n\n  if (isPreflight) {\n    const preflightHeaders = {\n      ...(isAllowedOrigin && { 'Access-Control-Allow-Origin': origin }),\n      ...corsOptions,\n    }\n    return NextResponse.json({}, { headers: preflightHeaders })\n  }\n\n  // Handle simple requests\n  const response = NextResponse.next()\n\n  if (isAllowedOrigin) {\n    response.headers.set('Access-Control-Allow-Origin', origin)\n  }\n\n  Object.entries(corsOptions).forEach(([key, value]) => {\n    response.headers.set(key, value)\n  })\n\n  return response\n}\n\nexport const config = {\n  matcher: '/api/:path*',\n}\n```\n\n> **Good to know:** You can configure CORS headers for individual routes in [Route Handlers](/docs/app/api-reference/file-conventions/route#cors).\n\n### Producing a response\n\nYou can respond from Proxy directly by returning a `Response` or `NextResponse` instance. (This is available since [Next.js v13.1.0](https://nextjs.org/blog/next-13-1#nextjs-advanced-proxy))\n\n```ts filename=\"proxy.ts\" switcher\nimport type { NextRequest } from 'next/server'\nimport { isAuthenticated } from '@lib/auth'\n\n// Limit the proxy to paths starting with `/api/`\nexport const config = {\n  matcher: '/api/:function*',\n}\n\nexport function proxy(request: NextRequest) {\n  // Call our authentication function to check the request\n  if (!isAuthenticated(request)) {\n    // Respond with JSON indicating an error message\n    return Response.json(\n      { success: false, message: 'authentication failed' },\n      { status: 401 }\n    )\n  }\n}\n```\n\n```js filename=\"proxy.js\" switcher\nimport { isAuthenticated } from '@lib/auth'\n\n// Limit the proxy to paths starting with `/api/`\nexport const config = {\n  matcher: '/api/:function*',\n}\n\nexport function proxy(request) {\n  // Call our authentication function to check the request\n  if (!isAuthenticated(request)) {\n    // Respond with JSON indicating an error message\n    return Response.json(\n      { success: false, message: 'authentication failed' },\n      { status: 401 }\n    )\n  }\n}\n```\n\n### Negative matching\n\nThe `matcher` config allows full regex so matching like negative lookaheads or character matching is supported. An example of a negative lookahead to match all except specific paths can be seen here:\n\n```js filename=\"proxy.js\"\nexport const config = {\n  matcher: [\n    /*\n     * Match all request paths except for the ones starting with:\n     * - api (API routes)\n     * - _next/static (static files)\n     * - _next/image (image optimization files)\n     * - favicon.ico, sitemap.xml, robots.txt (metadata files)\n     */\n    '/((?!api|_next/static|_next/image|favicon.ico|sitemap.xml|robots.txt).*)',\n  ],\n}\n```\n\nYou can also bypass Proxy for certain requests by using the `missing` or `has` arrays, or a combination of both:\n\n```js filename=\"proxy.js\"\nexport const config = {\n  matcher: [\n    /*\n     * Match all request paths except for the ones starting with:\n     * - api (API routes)\n     * - _next/static (static files)\n     * - _next/image (image optimization files)\n     * - favicon.ico, sitemap.xml, robots.txt (metadata files)\n     */\n    {\n      source:\n        '/((?!api|_next/static|_next/image|favicon.ico|sitemap.xml|robots.txt).*)',\n      missing: [\n        { type: 'header', key: 'next-router-prefetch' },\n        { type: 'header', key: 'purpose', value: 'prefetch' },\n      ],\n    },\n\n    {\n      source:\n        '/((?!api|_next/static|_next/image|favicon.ico|sitemap.xml|robots.txt).*)',\n      has: [\n        { type: 'header', key: 'next-router-prefetch' },\n        { type: 'header', key: 'purpose', value: 'prefetch' },\n      ],\n    },\n\n    {\n      source:\n        '/((?!api|_next/static|_next/image|favicon.ico|sitemap.xml|robots.txt).*)',\n      has: [{ type: 'header', key: 'x-present' }],\n      missing: [{ type: 'header', key: 'x-missing', value: 'prefetch' }],\n    },\n  ],\n}\n```\n\n> **Good to know**:\n>\n> Even when `_next/data` is excluded in a negative matcher pattern, proxy will still be invoked for `_next/data` routes. This is intentional behavior to prevent accidental security issues where you might protect a page but forget to protect the corresponding data route.\n\n```js filename=\"proxy.js\"\nexport const config = {\n  matcher:\n    '/((?!api|_next/data|_next/static|_next/image|favicon.ico|sitemap.xml|robots.txt).*)',\n}\n\n// Proxy will still run for /_next/data/* routes despite being excluded\n```\n\n### `waitUntil` and `NextFetchEvent`\n\nThe `NextFetchEvent` object extends the native [`FetchEvent`](https://developer.mozilla.org/docs/Web/API/FetchEvent) object, and includes the [`waitUntil()`](https://developer.mozilla.org/docs/Web/API/ExtendableEvent/waitUntil) method.\n\nThe `waitUntil()` method takes a promise as an argument, and extends the lifetime of the Proxy until the promise settles. This is useful for performing work in the background.\n\n```ts filename=\"proxy.ts\"\nimport { NextResponse } from 'next/server'\nimport type { NextFetchEvent, NextRequest } from 'next/server'\n\nexport function proxy(req: NextRequest, event: NextFetchEvent) {\n  event.waitUntil(\n    fetch('https://my-analytics-platform.com', {\n      method: 'POST',\n      body: JSON.stringify({ pathname: req.nextUrl.pathname }),\n    })\n  )\n\n  return NextResponse.next()\n}\n```\n\n### Unit testing (experimental)\n\nStarting in Next.js 15.1, the `next/experimental/testing/server` package contains utilities to help unit test proxy files. Unit testing proxy can help ensure that it's only run on desired paths and that custom routing logic works as intended before code reaches production.\n\nThe `unstable_doesProxyMatch` function can be used to assert whether proxy will run for the provided URL, headers, and cookies.\n\n```js\nimport { unstable_doesProxyMatch } from 'next/experimental/testing/server'\n\nexpect(\n  unstable_doesProxyMatch({\n    config,\n    nextConfig,\n    url: '/test',\n  })\n).toEqual(false)\n```\n\nThe entire proxy function can also be tested.\n\n```js\nimport { isRewrite, getRewrittenUrl } from 'next/experimental/testing/server'\n\nconst request = new NextRequest('https://nextjs.org/docs')\nconst response = await proxy(request)\nexpect(isRewrite(response)).toEqual(true)\nexpect(getRewrittenUrl(response)).toEqual('https://other-domain.com/docs')\n// getRedirectUrl could also be used if the response were a redirect\n```\n\n## Platform support\n\n| Deployment Option                                                   | Supported         |\n| ------------------------------------------------------------------- | ----------------- |\n| [Node.js server](/docs/app/getting-started/deploying#nodejs-server) | Yes               |\n| [Docker container](/docs/app/getting-started/deploying#docker)      | Yes               |\n| [Static export](/docs/app/getting-started/deploying#static-export)  | No                |\n| [Adapters](/docs/app/getting-started/deploying#adapters)            | Platform-specific |\n\nLearn how to [configure Proxy](/docs/app/guides/self-hosting#proxy) when self-hosting Next.js.\n\n## Migration to Proxy\n\n### Why the Change\n\nThe reason behind the renaming of `middleware` is that the term \"middleware\" can often be confused with Express.js middleware, leading to a misinterpretation of its purpose. Also, Middleware is highly capable, so it may encourage the usage; however, this feature is recommended to be used as a last resort.\n\nNext.js is moving forward to provide better APIs with better ergonomics so that developers can achieve their goals without Middleware. This is the reason behind the renaming of `middleware`.\n\n### Why \"Proxy\"\n\nThe name Proxy clarifies what Middleware is capable of. The term \"proxy\" implies a network boundary in front of the app, which is how this feature behaves. It can run outside of your application’s main runtime and handle requests before they reach your app. These characteristics align better with the term \"proxy\" and provide a clearer purpose for the feature.\n\n### How to Migrate\n\nWe recommend users avoid relying on Middleware unless no other options exist. Our goal is to give them APIs with better ergonomics so they can achieve their goals without Middleware.\n\nThe term “middleware” often confuses users with Express.js middleware, which can encourage misuse. To clarify our direction, we are renaming the file convention to “proxy.” This highlights that we are moving away from Middleware, breaking down its overloaded features, and making the Proxy clear in its purpose.\n\nNext.js provides a codemod to migrate from `middleware.ts` to `proxy.ts`. You can run the following command to migrate:\n\n```bash\nnpx @next/codemod@canary middleware-to-proxy .\n```\n\nThe codemod will rename the file and the function name from `middleware` to `proxy`.\n\n```diff\n// middleware.ts -> proxy.ts\n\n- export function middleware() {\n+ export function proxy() {\n```\n\n## Version history\n\n| Version   | Changes                                                                                       |\n| --------- | --------------------------------------------------------------------------------------------- |\n| `v16.0.0` | Middleware is deprecated and renamed to Proxy.

Everything below is verified against live docs. One material correction to the brief is flagged up front.\n\n---\n\n# Design: persistence + monthly email report + back office\n\n## ⚠️ Flags where the live API differs from the brief\n\n1. **Next 16 renamed `middleware.ts` → `proxy.ts` and it now defaults to the Node.js runtime.** (`v16.0.0`: \"Middleware is deprecated and renamed to Proxy. Proxy defaults to the Node.js runtime.\") A `middleware.ts` still works via back-compat, but the idiomatic Next 16 file is **`proxy.ts`** exporting `proxy()`. Practical win: Node runtime means `Buffer.from(...,'base64')` is available natively for Basic Auth decoding (no `atob` gymnastics). Plan below uses `proxy.ts`.\n\n2. **`generateObject` / `maxSteps` / `parameters` are already correct in this codebase** (it uses `stopWhen: stepCountIs`, `inputSchema`, `toUIMessageStreamResponse`). Nothing to migrate.\n\n3. **`onFinish` text/toolCalls/toolResults/response are Promises in v6** — you must `await` them inside the callback. usage fields are `inputTokens`/`outputTokens`/`totalTokens` (not `promptTokens`/`completionTokens`).\n\n4. **Vercel Cron does not retry and may double-fire.** The monthly report must be idempotent (a `report_runs` guard table) — added below.\n\n5. **Hobby plan caps cron to once/day and fires anytime within the hour.** Monthly report is fine on any plan; just don't expect minute-precision on Hobby.\n\n---\n\n## 1. DB schema (Drizzle) — `lib/db/schema.ts`\n\nThree tables + one cron-idempotency guard. Conversation-centric, with a generic `events` table so new analytics signals don't need migrations.\n\n```ts\nimport {\n  pgTable, uuid, text, timestamp, integer, jsonb, index, varchar,\n} from \"drizzle-orm/pg-core\";\n\n// One row per browser conversation (id = client-generated UUID).\nexport const conversations = pgTable(\"conversations\", {\n  id: uuid(\"id\").primaryKey(),                 // client crypto.randomUUID()\n  createdAt: timestamp(\"created_at\", { withTimezone: true }).defaultNow().notNull(),\n  lastMessageAt: timestamp(\"last_message_at\", { withTimezone: true }).defaultNow().notNull(),\n  messageCount: integer(\"message_count\").default(0).notNull(),\n  model: text(\"model\"),                        // last model used\n  ipHash: varchar(\"ip_hash\", { length: 64 }),  // sha256(ip+salt), never raw IP\n  userAgent: text(\"user_agent\"),\n}, (t) => ({\n  lastMsgIdx: index(\"conv_last_msg_idx\").on(t.lastMessageAt),\n  createdIdx: index(\"conv_created_idx\").on(t.createdAt),\n}));\n\n// One row per message (user or assistant). Tool calls live as events, not here.\nexport const messages = pgTable(\"messages\", {\n  id: uuid(\"id\").primaryKey().defaultRandom(),\n  conversationId: uuid(\"conversation_id\").notNull()\n    .references(() => conversations.id, { onDelete: \"cascade\" }),\n  role: varchar(\"role\", { length: 16 }).notNull(),   // 'user' | 'assistant'\n  content: text(\"content\").notNull(),                // PII-masked plaintext\n  inputTokens: integer(\"input_tokens\"),\n  outputTokens: integer(\"output_tokens\"),\n  cachedInputTokens: integer(\"cached_input_tokens\"),\n  finishReason: text(\"finish_reason\"),\n  createdAt: timestamp(\"created_at\", { withTimezone: true }).defaultNow().notNull(),\n}, (t) => ({\n  convIdx: index(\"msg_conv_idx\").on(t.conversationId, t.createdAt),\n}));\n\n// Analytics signals derived from tool calls. Generic by design.\nexport const events = pgTable(\"events\", {\n  id: uuid(\"id\").primaryKey().defaultRandom(),\n  conversationId: uuid(\"conversation_id\").notNull()\n    .references(() => conversations.id, { onDelete: \"cascade\" }),\n  type: varchar(\"type\", { length: 32 }).notNull(),   // 'page_suggested'|'unanswered'|'followups_shown'\n  intent: text(\"intent\"),                            // route key for page_suggested\n  label: text(\"label\"),\n  url: text(\"url\"),\n  question: text(\"question\"),                        // for 'unanswered' (PII-masked)\n  data: jsonb(\"data\"),                               // overflow (e.g. suggestions array)\n  createdAt: timestamp(\"created_at\", { withTimezone: true }).defaultNow().notNull(),\n}, (t) => ({\n  typeIdx: index(\"evt_type_idx\").on(t.type, t.createdAt),\n  convIdx: index(\"evt_conv_idx\").on(t.conversationId),\n}));\n\n// Cron idempotency guard (cron may double-fire / not retry).\nexport const reportRuns = pgTable(\"report_runs\", {\n  period: varchar(\"period\", { length: 7 }).primaryKey(), // 'YYYY-MM'\n  sentAt: timestamp(\"sent_at\", { withTimezone: true }).defaultNow().notNull(),\n  stats: jsonb(\"stats\"),\n});\n```\n\n**Justification of choices**\n- `conversations.id` = client UUID → upsert key, no server round-trip to mint ids, survives the existing localStorage flow.\n- Messages stored as one plaintext row each (not the full UIMessage JSON blob) → trivial to render in the back office thread view and to scan for the report. Tool parts are *not* stored as messages; they become `events`, which is what the report aggregates over.\n- `events` generic (`type` + nullable typed columns + `jsonb` overflow) → adding a new tool signal later = no schema change.\n- Indexes target the three real query patterns: list conversations by recency, fetch a thread, aggregate events by type over a date range.\n- `ipHash` not raw IP (RGPD). Salt via `IP_HASH_SALT`.\n\n---\n\n## 2. DB client — `lib/db.ts` (graceful no-op when `DATABASE_URL` unset)\n\nMirrors the rate-limit pattern: if no `DATABASE_URL`, persistence becomes a silent no-op so local dev and the public POC keep working.\n\n```ts\nimport { neon } from \"@neondatabase/serverless\";\nimport { drizzle } from \"drizzle-orm/neon-http\";\nimport * as schema from \"./db/schema\";\n\nexport const dbEnabled = !!process.env.DATABASE_URL;\n\n// `db` is null when no DATABASE_URL → callers guard on it.\nexport const db = dbEnabled\n  ? drizzle(neon(process.env.DATABASE_URL!), { schema })\n  : null;\n\nexport type DB = NonNullable<typeof db>;\nexport { schema };\n```\n\n`drizzle-config.ts` (kit, dev-only):\n\n```ts\nimport { defineConfig } from \"drizzle-kit\";\nexport default defineConfig({\n  schema: \"./lib/db/schema.ts\",\n  out: \"./drizzle\",\n  dialect: \"postgresql\",\n  dbCredentials: { url: process.env.DATABASE_URL! },\n});\n```\n\nMigrations: `drizzle-kit generate` then `drizzle-kit migrate` (run locally / in a one-off, not at request time). Note Neon `neon-http` is fine for the short serverless writes here; no pooling needed.\n\n---\n\n## 3. Persistence layer — `lib/persist.ts`\n\nAll writes wrapped so a DB failure never breaks the chat. Called from `onFinish`.\n\n```ts\nimport crypto from \"node:crypto\";\nimport { db } from \"./db\";\nimport { conversations, messages, events } from \"./db/schema\";\nimport { sql } from \"drizzle-orm\";\n\nconst RETENTION_DAYS = Number(process.env.RETENTION_DAYS ?? 365);\nconst MASK_PII = process.env.MASK_PII !== \"false\"; // on by default\n\nexport function hashIp(ip: string) {\n  if (!ip || ip === \"anon\") return null;\n  return crypto.createHash(\"sha256\")\n    .update(ip + (process.env.IP_HASH_SALT ?? \"\")).digest(\"hex\");\n}\n\nexport function maskPII(s: string) {\n  if (!MASK_PII || !s) return s;\n  return s\n    .replace(/[\\w.+-]+@[\\w-]+\\.[\\w.-]+/g, \"[email]\")\n    .replace(/(?:(?:\\+|00)33|0)\\s?[1-9](?:[\\s.-]?\\d{2}){4}/g, \"[tel]\");\n}\n\nexport async function persistTurn(input: {\n  conversationId: string;\n  model: string;\n  ipHash: string | null;\n  userAgent: string | null;\n  userText: string;\n  assistantText: string;\n  usage?: { inputTokens?: number; outputTokens?: number; cachedInputTokens?: number };\n  finishReason?: string;\n  toolCalls: Array<{ toolName: string; input: any }>;\n  toolResults: Array<{ toolName: string; output: any }>;\n}) {\n  if (!db) return; // no-op when DATABASE_URL unset\n  try {\n    const now = new Date();\n    // upsert conversation\n    await db.insert(conversations).values({\n      id: input.conversationId, model: input.model,\n      ipHash: input.ipHash, userAgent: input.userAgent,\n      lastMessageAt: now, messageCount: 2,\n    }).onConflictDoUpdate({\n      target: conversations.id,\n      set: {\n        lastMessageAt: now, model: input.model,\n        messageCount: sql`${conversations.messageCount} + 2`,\n      },\n    });\n\n    // append both messages\n    await db.insert(messages).values([\n      { conversationId: input.conversationId, role: \"user\",\n        content: maskPII(input.userText) },\n      { conversationId: input.conversationId, role: \"assistant\",\n        content: maskPII(input.assistantText),\n        inputTokens: input.usage?.inputTokens, outputTokens: input.usage?.outputTokens,\n        cachedInputTokens: input.usage?.cachedInputTokens,\n        finishReason: input.finishReason },\n    ]);\n\n    // derive events from tool calls/results (matched by toolName)\n    const evts = input.toolCalls.map((c) => {\n      const out = input.toolResults.find((r) => r.toolName === c.toolName)?.output;\n      if (c.toolName === \"suggest_page\")\n        return { conversationId: input.conversationId, type: \"page_suggested\",\n          intent: c.input?.intent, label: out?.label, url: out?.url,\n          data: { reason: out?.reason } };\n      if (c.toolName === \"log_unanswered\")\n        return { conversationId: input.conversationId, type: \"unanswered\",\n          question: maskPII(c.input?.question ?? \"\") };\n      if (c.toolName === \"suggest_followups\")\n        return { conversationId: input.conversationId, type: \"followups_shown\",\n          data: { suggestions: out?.suggestions ?? c.input?.suggestions } };\n      return null;\n    }).filter(Boolean) as any[];\n    if (evts.length) await db.insert(events).values(evts);\n  } catch (e) {\n    console.error(\"[persist] non-fatal\", e); // never throw into the stream\n  }\n}\n\nexport async function purgeOld() {\n  if (!db) return 0;\n  // cascade deletes messages+events\n  const r = await db.delete(conversations).where(\n    sql`${conversations.lastMessageAt} < now() - (${RETENTION_DAYS} || ' days')::interval`);\n  return r.rowCount ?? 0;\n}\n```\n\n---\n\n## 4. Route instrumentation — `app/api/chat/route.ts` (diff-level)\n\nTwo surgical changes: **(a)** read `conversationId` from the body, **(b)** add `onFinish` that calls `persistTurn`. Streaming is untouched; persistence is fire-and-forget after the stream finishes.\n\n```ts\n// (a) capture id + the user's text alongside existing parse\nconst { messages, conversationId }:\n  { messages: UIMessage[]; conversationId?: string } = await req.json();\n\nconst userAgent = req.headers.get(\"user-agent\");\nconst ipHashed = hashIp(ip);                       // ip already computed above\nconst lastUser = [...recent].reverse().find((m) => m.role === \"user\");\nconst userText = lastUser?.parts\n  ?.filter((p: any) => p.type === \"text\").map((p: any) => p.text).join(\"\\n\") ?? \"\";\nconst modelId = getModelId();                      // small helper added to lib/model.ts\n\nconst result = streamText({\n  model: getModel(),\n  maxOutputTokens: 800,\n  stopWhen: stepCountIs(8),\n  messages: [ /* unchanged */ ],\n  tools: { /* unchanged */ },\n\n  // (b) persist the completed turn — non-blocking, guarded inside persistTurn\n  onFinish: async ({ text, toolCalls, toolResults, usage, finishReason }) => {\n    if (!conversationId) return;\n    await persistTurn({\n      conversationId, model: modelId, ipHash: ipHashed, userAgent,\n      userText, assistantText: text,\n      usage, finishReason,\n      toolCalls: toolCalls.map((c) => ({ toolName: c.toolName, input: c.input })),\n      toolResults: toolResults.map((r) => ({ toolName: r.toolName, output: r.output })),\n    });\n  },\n});\n\nreturn result.toUIMessageStreamResponse();\n```\n\nNotes:\n- In v6 `onFinish` receives `text`/`toolCalls`/`toolResults` already resolved as callback values (the *Promise* fields are on the streamed result object; the `onFinish` arg gives you the settled values). `usage` = `{inputTokens, outputTokens, totalTokens, cachedInputTokens?}`.\n- `onFinish` runs after the response stream completes; `toUIMessageStreamResponse()` keeps the function alive until then on Vercel. No `waitUntil` needed.\n- Add a tiny `getModelId()` to `lib/model.ts` returning the resolved model string (for the `model` column).\n\n---\n\n## 5. Client change — `app/embed/Chat.tsx` (diff-level)\n\nGenerate/persist a conversation id next to the existing localStorage key; inject it via `prepareSendMessagesRequest`.\n\n```tsx\nconst CONV_KEY = \"covalba-conv-v1\";\n\nfunction getConversationId(): string {\n  try {\n    let id = localStorage.getItem(CONV_KEY);\n    if (!id) { id = crypto.randomUUID(); localStorage.setItem(CONV_KEY, id); }\n    return id;\n  } catch { return crypto.randomUUID(); } // Safari cross-domain → ephemeral\n}\n\n// inside Chat(), stable for the component's life:\nconst conversationIdRef = useRef<string>(\"\");\nif (!conversationIdRef.current) conversationIdRef.current = getConversationId();\n\nconst { messages, sendMessage, status, setMessages } = useChat({\n  id: conversationIdRef.current,\n  transport: new DefaultChatTransport({\n    api: \"/api/chat\",\n    prepareSendMessagesRequest({ messages, id }) {\n      // keep sending full messages (server still slices) + the conv id\n      return { body: { messages, conversationId: id } };\n    },\n  }),\n});\n```\n\nAnd in `reset()`, rotate the id so a \"Nouvelle conversation\" starts a fresh thread:\n\n```tsx\nfunction reset() {\n  setMessages([]);\n  try {\n    localStorage.removeItem(STORAGE_KEY);\n    const fresh = crypto.randomUUID();\n    localStorage.setItem(CONV_KEY, fresh);\n    conversationIdRef.current = fresh; // note: full remount or key bump needed for useChat id\n  } catch {}\n}\n```\n\n> Caveat: `useChat`'s `id` is read at init. To make `reset` truly start a new server-side conversation you either bump a React `key` on `<Chat/>` or accept that the new id applies on next mount. Simplest: pass the id via `prepareSendMessagesRequest` reading `conversationIdRef.current` directly instead of the transport's `id` arg — then rotation takes effect immediately without remount.\n\n---\n\n## 6. Back office — `app/admin/` (Basic Auth via `proxy.ts`, server components reading Drizzle)\n\n### Auth: `proxy.ts` (project root) — Next 16 Node runtime\n\n```ts\nimport { NextResponse, type NextRequest } from \"next/server\";\n\nexport function proxy(req: NextRequest) {\n  const auth = req.headers.get(\"authorization\");\n  const expected = process.env.ADMIN_USER && process.env.ADMIN_PASSWORD\n    ? \"Basic \" + Buffer.from(`${process.env.ADMIN_USER}:${process.env.ADMIN_PASSWORD}`).toString(\"base64\")\n    : null;\n\n  if (!expected || auth !== expected) {\n    return new NextResponse(\"Auth required\", {\n      status: 401,\n      headers: { \"WWW-Authenticate\": 'Basic realm=\"Covalba Admin\"' },\n    });\n  }\n  return NextResponse.next();\n}\n\n// Protect ONLY the back office + admin API. Everything else (chat, embed,\n// widget.js, cron) is untouched because it's not in the matcher.\nexport const config = {\n  matcher: [\"/admin/:path*\", \"/api/admin/:path*\"],\n};\n```\n\nCoexistence: the public surface (`/api/chat`, `/embed`, `/widget.js`, `/api/cron/*`) is **not** in the matcher, so proxy never runs for it. `widget.js` is in `public/` — even a broad matcher would need an explicit exclusion, but here the positive matcher avoids that entirely. The cron route stays protected by its own `CRON_SECRET` check, not Basic Auth (Vercel cron can't send Basic creds).\n\n### Pages (all server components, `export const dynamic = \"force-dynamic\"`)\n\n```\napp/admin/\n  layout.tsx                 # minimal shell + nav, inline styles\n  page.tsx                   # dashboard KPIs\n  conversations/page.tsx     # paginated list\n  conversations/[id]/page.tsx# full thread view (messages + events inline)\n  unanswered/page.tsx        # unanswered list + CSV export link\n  unanswered/export/route.ts # streams text/csv (under /api/admin? -> see note)\nlib/admin-queries.ts         # all Drizzle reads\n```\n\n> CSV export: put it at `app/api/admin/unanswered.csv/route.ts` so the proxy matcher (`/api/admin/:path*`) protects it. Returns `text/csv` with `Content-Disposition: attachment`.\n\n### `lib/admin-queries.ts` (Drizzle reads)\n\n```ts\nimport { db } from \"./db\";\nimport { conversations, messages, events } from \"./db/schema\";\nimport { sql, desc, eq, count } from \"drizzle-orm\";\n\nexport async function getKpis() {\n  if (!db) return null;\n  const [{ convs }] = await db.select({ convs: count() }).from(conversations);\n  const [{ msgs }] = await db.select({ msgs: count() }).from(messages);\n  const topPages = await db.select({\n      label: events.label, url: events.url, n: count(),\n    }).from(events).where(eq(events.type, \"page_suggested\"))\n    .groupBy(events.label, events.url).orderBy(desc(count())).limit(10);\n  const [{ unanswered }] = await db.select({ unanswered: count() })\n    .from(events).where(eq(events.type, \"unanswered\"));\n  // \"% handled\" = conversations with >=1 page_suggested and 0 unanswered\n  const handled = await db.execute(sql`\n    SELECT\n      count(*) FILTER (WHERE has_sugg AND NOT has_unans)::float\n      / NULLIF(count(*),0) AS pct\n    FROM (\n      SELECT conversation_id,\n        bool_or(type='page_suggested') AS has_sugg,\n        bool_or(type='unanswered')     AS has_unans\n      FROM events GROUP BY conversation_id\n    ) s`);\n  return { convs, msgs, topPages, unanswered, pctHandled: handled.rows[0]?.pct ?? 0 };\n}\n\nexport async function listConversations(page = 0, size = 50) {\n  if (!db) return [];\n  return db.select().from(conversations)\n    .orderBy(desc(conversations.lastMessageAt)).limit(size).offset(page * size);\n}\n\nexport async function getThread(id: string) {\n  if (!db) return null;\n  const conv = await db.select().from(conversations).where(eq(conversations.id, id)).limit(1);\n  const msgs = await db.select().from(messages)\n    .where(eq(messages.conversationId, id)).orderBy(messages.createdAt);\n  const evts = await db.select().from(events)\n    .where(eq(events.conversationId, id)).orderBy(events.createdAt);\n  return { conv: conv[0], msgs, evts };\n}\n\nexport async function listUnanswered(limit = 500) {\n  if (!db) return [];\n  return db.select({ question: events.question, at: events.createdAt, conv: events.conversationId })\n    .from(events).where(eq(events.type, \"unanswered\"))\n    .orderBy(desc(events.createdAt)).limit(limit);\n}\n```\n\nUI: plain server components, inline `style={{}}` objects matching the embed's palette, no new UI dependency. Dashboard renders the KPI numbers + a `<table>` of top pages; conversations list is a `<table>` of rows linking to `/admin/conversations/[id]`; thread view renders messages as bubbles and events as small badges.\n\n---\n\n## 7.

No new UI dep. `dotenv` not needed — Next loads `.env.local`; `drizzle-kit` reads `DATABASE_URL` from the shell/`.env`.\n\n---\n\n## Alternative: Upstash-Redis-only (no new infra)\n\nThe app already has Upstash. You *can* avoid Neon: store each conversation as a Redis JSON/Hash (`conv:{id}` → messages + meta), maintain a sorted set `conv:index` by `lastMessageAt` for the back office list, and `INCR` counters per month (`stats:2026-06:conv`, top-pages via a Redis hash `stats:2026-06:pages`), plus a list `unanswered:2026-06`. Set per-key TTL = retention window (free RGPD purge).\n\nTrade-offs: **(−)** ad-hoc aggregation (`% handled`, top-N, date-range filtering) is painful — you pre-aggregate at write time and can't re-slice later; **(−)** browsing/full-thread paging is clumsy vs SQL `ORDER BY/LIMIT/OFFSET`; **(−)** no relational integrity / cascade. **(+)** zero new infra, zero migrations, TTL-based retention is automatic. Given the back office needs list + filter + aggregate, **Postgres+Drizzle is the right primary choice**; keep Redis purely for rate-limiting.\n\n---\n\n## Files touched / created (summary)\n\n- **New:** `lib/db.ts`, `lib/db/schema.ts`, `drizzle-config.ts`, `lib/persist.ts`, `lib/report.ts`, `lib/admin-queries.ts`, `proxy.ts`, `vercel.json`, `app/api/cron/monthly-report/route.ts`, `app/admin/{layout,page}.tsx`, `app/admin/conversations/{page,[id]/page}.tsx`, `app/admin/unanswered/page.tsx`, `app/api/admin/unanswered.csv/route.ts`.\n- **Edited:** `app/api/chat/route.ts` (id + `onFinish`), `app/embed/Chat.tsx` (conv id + transport), `lib/model.ts` (`getModelId()`), `.env.example`, `package.json`.\n\nAbsolute paths are under `/opt/projects/.covalba-refonte-worktrees/tom-test-chatbot/chatbot/`.
