# Sentry Next.js SDK

Opinionated wizard that scans your Next.js project and guides you through complete Sentry setup across all three runtimes: browser, Node.js server, and Edge.

## Invoke This Skill When

- User asks to "add Sentry to Next.js" or "set up Sentry" in a Next.js app
- User wants to install or configure `@sentry/nextjs`
- User wants error monitoring, tracing, session replay, logging, or profiling for Next.js
- User asks about `instrumentation.ts`, `withSentryConfig()`, or `global-error.tsx`
- User wants to capture server actions, server component errors, or edge runtime errors

> **Note:** SDK versions and APIs below reflect current Sentry docs at time of writing (`@sentry/nextjs` ≥8.28.0).
> Always verify against [docs.sentry.io/platforms/javascript/guides/nextjs/](https://docs.sentry.io/platforms/javascript/guides/nextjs/) before implementing.

---

## Phase 1: Detect

Run these commands to understand the project before making any recommendations:

```bash
# Detect Next.js version and existing Sentry
cat package.json | grep -E '"next"|"@sentry/'

# Detect router type (App Router vs Pages Router)
ls src/app app src/pages pages 2>/dev/null

# Check for existing Sentry config files
ls instrumentation.ts instrumentation-client.ts sentry.server.config.ts sentry.edge.config.ts 2>/dev/null
ls src/instrumentation.ts src/instrumentation-client.ts 2>/dev/null

# Check next.config
ls next.config.ts next.config.js next.config.mjs 2>/dev/null

# Check for existing error boundaries
find . -name "global-error.tsx" -o -name "_error.tsx" 2>/dev/null | grep -v node_modules

# Check build tool
cat package.json | grep -E '"turbopack"|"webpack"'

# Check for logging libraries
cat package.json | grep -E '"pino"|"winston"|"bunyan"'

# Check for companion backend
ls ../backend ../server ../api 2>/dev/null
cat ../go.mod ../requirements.txt ../Gemfile 2>/dev/null | head -3
```

**What to determine:**

| Question                          | Impact                                                                      |
| --------------------------------- | --------------------------------------------------------------------------- |
| Next.js version?                  | 13+ required; 15+ needed for Turbopack support                              |
| App Router or Pages Router?       | Determines error boundary files needed (`global-error.tsx` vs `_error.tsx`) |
| `@sentry/nextjs` already present? | Skip install, go to feature config                                          |
| Existing `instrumentation.ts`?    | Merge Sentry into it rather than replace                                    |
| Turbopack in use?                 | Tree-shaking in `withSentryConfig` is webpack-only                          |
| Logging library detected?         | Recommend Sentry Logs integration                                           |
| Backend directory found?          | Trigger Phase 4 cross-link suggestion                                       |

---

## Phase 2: Recommend

Present a concrete recommendation based on what you found. Don't ask open-ended questions — lead with a proposal:

**Recommended (core coverage):**

- ✅ **Error Monitoring** — always; captures server errors, client errors, server actions, and unhandled promise rejections
- ✅ **Tracing** — server-side request tracing + client-side navigation spans across all runtimes
- ✅ **Session Replay** — recommended for user-facing apps; records sessions around errors

**Optional (enhanced observability):**

- ⚡ **Logging** — structured logs via `Sentry.logger.*`; recommend when `pino`/`winston` or log search is needed
- ⚡ **Profiling** — continuous profiling; requires `Document-Policy: js-profiling` header
- ⚡ **AI Monitoring** — OpenAI, Vercel AI SDK, Anthropic; recommend when AI/LLM calls detected
- ⚡ **Crons** — detect missed/failed scheduled jobs; recommend when cron patterns detected
- ⚡ **Metrics** — custom metrics via `Sentry.metrics.*`; recommend when custom KPIs or business metrics needed

**Recommendation logic:**

| Feature          | Recommend when...                                                                |
| ---------------- | -------------------------------------------------------------------------------- |
| Error Monitoring | **Always** — non-negotiable baseline                                             |
| Tracing          | **Always for Next.js** — server route tracing + client navigation are high-value |
| Session Replay   | User-facing app, login flows, or checkout pages                                  |
| Logging          | App uses structured logging or needs log-to-trace correlation                    |
| Profiling        | Performance-critical app; client sets `Document-Policy: js-profiling`            |
| AI Monitoring    | App makes OpenAI, Vercel AI SDK, or Anthropic calls                              |
| Crons            | App has Vercel Cron jobs, scheduled API routes, or `node-cron` usage             |
| Metrics          | App needs custom counters, gauges, or histograms via `Sentry.metrics.*`          |

Propose: _"I recommend setting up Error Monitoring + Tracing + Session Replay. Want me to also add Logging or Profiling?"_

## Phase 3: Guide

### Option 1: Wizard (Recommended)

> **You need to run this yourself** — the wizard opens a browser for login and requires interactive input that the agent can't handle. Copy-paste into your terminal:
>
> ```
> npx @sentry/wizard@latest -i nextjs
> ```
>
> It handles login, org/project selection, SDK installation, config files (`instrumentation-client.ts`, `sentry.server.config.ts`, `sentry.edge.config.ts`, `instrumentation.ts`), `next.config.ts` wrapping, source map upload, and adds a `/sentry-example-page`.
>
> **Once it finishes, come back and skip to [Verification](#verification).**

If the user skips the wizard, proceed with Option 2 (Manual Setup) below.

---

### Option 2: Manual Setup

#### Install

```bash
npm install @sentry/nextjs --save
```

#### Create `instrumentation-client.ts` — Browser / Client Runtime

> Older docs used `sentry.client.config.ts` — the current pattern is `instrumentation-client.ts`.

```typescript
import * as Sentry from '@sentry/nextjs';

Sentry.init({
  dsn: process.env.NEXT_PUBLIC_SENTRY_DSN ?? '___PUBLIC_DSN___',

  sendDefaultPii: true,

  // 100% in dev, 10% in production
  tracesSampleRate: process.env.NODE_ENV === 'development' ? 1.0 : 0.1,

  // Session Replay: 10% of all sessions, 100% of sessions with errors
  replaysSessionSampleRate: 0.1,
  replaysOnErrorSampleRate: 1.0,

  enableLogs: true,

  integrations: [
    Sentry.replayIntegration(),
    // Optional: user feedback widget
    // Sentry.feedbackIntegration({ colorScheme: "system" }),
  ],
});

// Hook into App Router navigation transitions (App Router only)
export const onRouterTransitionStart = Sentry.captureRouterTransitionStart;
```

#### Create `sentry.server.config.ts` — Node.js Server Runtime

```typescript
import * as Sentry from '@sentry/nextjs';

Sentry.init({
  dsn: process.env.SENTRY_DSN ?? '___DSN___',

  sendDefaultPii: true,
  tracesSampleRate: process.env.NODE_ENV === 'development' ? 1.0 : 0.1,

  // Attach local variable values to stack frames
  includeLocalVariables: true,

  enableLogs: true,
});
```

#### Create `sentry.edge.config.ts` — Edge Runtime

```typescript
import * as Sentry from '@sentry/nextjs';

Sentry.init({
  dsn: process.env.SENTRY_DSN ?? '___DSN___',

  sendDefaultPii: true,
  tracesSampleRate: process.env.NODE_ENV === 'development' ? 1.0 : 0.1,

  enableLogs: true,
});
```

#### Create `instrumentation.ts` — Server-Side Registration Hook

> Requires `experimental.instrumentationHook: true` in `next.config` for Next.js < 14.0.4. It's stable in 14.0.4+.

```typescript
import * as Sentry from '@sentry/nextjs';

export async function register() {
  if (process.env.NEXT_RUNTIME === 'nodejs') {
    await import('./sentry.server.config');
  }

  if (process.env.NEXT_RUNTIME === 'edge') {
    await import('./sentry.edge.config');
  }
}

// Automatically captures all unhandled server-side request errors
// Requires @sentry/nextjs >= 8.28.0
export const onRequestError = Sentry.captureRequestError;
```

**Runtime dispatch:**

| `NEXT_RUNTIME`    | Config file loaded                                          |
| ----------------- | ----------------------------------------------------------- |
| `"nodejs"`        | `sentry.server.config.ts`                                   |
| `"edge"`          | `sentry.edge.config.ts`                                     |
| _(client bundle)_ | `instrumentation-client.ts` (Next.js handles this directly) |

#### App Router: Create `app/global-error.tsx`

This catches errors in the root layout and React render errors:

```tsx
'use client';

import * as Sentry from '@sentry/nextjs';
import NextError from 'next/error';
import { useEffect } from 'react';

export default function GlobalError({ error }: { error: Error & { digest?: string } }) {
  useEffect(() => {
    Sentry.captureException(error);
  }, [error]);

  return (
    <html>
      <body>
        <NextError statusCode={0} />
      </body>
    </html>
  );
}
```

#### Pages Router: Update `pages/_error.tsx`

```tsx
import * as Sentry from '@sentry/nextjs';
import type { NextPageContext } from 'next';
import NextErrorComponent from 'next/error';

type ErrorProps = { statusCode: number };

export default function CustomError({ statusCode }: ErrorProps) {
  return <NextErrorComponent statusCode={statusCode} />;
}

CustomError.getInitialProps = async (ctx: NextPageContext) => {
  await Sentry.captureUnderscoreErrorException(ctx);
  return NextErrorComponent.getInitialProps(ctx);
};
```

#### Wrap `next.config.ts` with `withSentryConfig()`

```typescript
import type { NextConfig } from 'next';
import { withSentryConfig } from '@sentry/nextjs';

const nextConfig: NextConfig = {
  // your existing Next.js config
};

export default withSentryConfig(nextConfig, {
  org: '___ORG_SLUG___',
  project: '___PROJECT_SLUG___',

  // Source map upload auth token (see Source Maps section below)
  authToken: process.env.SENTRY_AUTH_TOKEN,

  // Upload wider set of client source files for better stack trace resolution
  widenClientFileUpload: true,

  // Create a proxy API route to bypass ad-blockers
  tunnelRoute: '/monitoring',

  // Suppress non-CI output
  silent: !process.env.CI,
});
```

#### Exclude Tunnel Route from Middleware

If you have `middleware.ts`, exclude the tunnel path from auth or redirect logic:

```typescript
// middleware.ts
export const config = {
  matcher: [
    // Exclude monitoring route, Next.js internals, and static files
    '/((?!monitoring|_next/static|_next/image|favicon.ico).*)',
  ],
};
```

---

### Source Maps Setup

Source maps make production stack traces readable — without them, you see minified code. This is non-negotiable for production apps.

**Step 1: Generate a Sentry auth token**

Go to [sentry.io/settings/auth-tokens/](https://sentry.io/settings/auth-tokens/) and create a token with `project:releases` and `org:read` scopes.

**Step 2: Set environment variables**

```bash
# .env.sentry-build-plugin  (gitignore this file)
SENTRY_AUTH_TOKEN=sntrys_eyJ...
```

Or set in CI secrets:

```bash
SENTRY_AUTH_TOKEN=sntrys_eyJ...
SENTRY_ORG=my-org        # optional if set in next.config
SENTRY_PROJECT=my-project # optional if set in next.config
```

**Step 3: Add to `.gitignore`**

```
.env.sentry-build-plugin
```

**Step 4: Verify `authToken` is wired in `next.config.ts`**

```typescript
withSentryConfig(nextConfig, {
  org: 'my-org',
  project: 'my-project',
  authToken: process.env.SENTRY_AUTH_TOKEN, // reads from .env.sentry-build-plugin or CI env
  widenClientFileUpload: true,
});
```

Source maps are uploaded automatically on every `next build`.

### For Each Agreed Feature

Load the corresponding reference file and follow its steps:

| Feature          | Reference file                   | Load when...                                                                                       |
| ---------------- | -------------------------------- | -------------------------------------------------------------------------------------------------- |
| Error Monitoring | `references/error-monitoring.md` | Always (baseline) — App Router error boundaries, Pages Router `_error.tsx`, server action wrapping |
| Tracing          | `references/tracing.md`          | Server-side request tracing, client navigation, distributed tracing, `tracePropagationTargets`     |
| Session Replay   | `references/session-replay.md`   | User-facing app; privacy masking, canvas recording, network capture                                |
| Logging          | `references/logging.md`          | Structured logs, `Sentry.logger.*`, log-to-trace correlation                                       |
| Profiling        | `references/profiling.md`        | Continuous profiling, `Document-Policy` header, `nodeProfilingIntegration`                         |
| AI Monitoring    | `references/ai-monitoring.md`    | App uses OpenAI, Vercel AI SDK, or Anthropic                                                       |
| Crons            | `references/crons.md`            | Vercel Cron, scheduled API routes, `node-cron`                                                     |
| Metrics          | `references/metrics.md`          | Custom counters, gauges, distributions via `Sentry.metrics.*`                                      |

For each feature: read the reference file, follow its steps exactly, and verify before moving on.

---

## Verification

After wizard or manual setup, verify Sentry is working:

```typescript
// Add temporarily to a server action or API route, then remove
import * as Sentry from '@sentry/nextjs';

throw new Error('Sentry test error — delete me');
// or
Sentry.captureException(new Error('Sentry test error — delete me'));
```

Then check your [Sentry Issues dashboard](https://sentry.io/issues/) — the error should appear within ~30 seconds.

**Verification checklist:**

| Check                  | How                                           |
| ---------------------- | --------------------------------------------- |
| Client errors captured | Throw in a client component, verify in Sentry |
| Server errors captured | Throw in a server action or API route         |
| Edge errors captured   | Throw in middleware or edge route handler     |
| Source maps working    | Check stack trace shows readable file names   |
| Session Replay working | Check Replays tab in Sentry dashboard         |

## Phase 4: Cross-Link

After completing Next.js setup, check for companion services:

```bash
# Check for backend services in adjacent directories
ls ../backend ../server ../api ../services 2>/dev/null

# Check for backend language indicators
cat ../go.mod 2>/dev/null | head -3
cat ../requirements.txt ../pyproject.toml 2>/dev/null | head -3
cat ../Gemfile 2>/dev/null | head -3
cat ../pom.xml ../build.gradle 2>/dev/null | head -3
```

If a backend is found, suggest the matching SDK skill:

| Backend detected                              | Suggest skill                                                                                                                           |
| --------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------- |

Connecting frontend and backend with the same DSN or linked projects enables **distributed tracing** — stack traces that span your browser, Next.js server, and backend API in a single trace view.

## Troubleshooting

| Issue                                        | Cause                                             | Solution                                                                                             |
| -------------------------------------------- | ------------------------------------------------- | ---------------------------------------------------------------------------------------------------- |
| Events not appearing                         | DSN misconfigured or `debug: false` hiding errors | Set `debug: true` temporarily; check browser network tab for requests to `sentry.io`                 |
| Stack traces show minified code              | Source maps not uploading                         | Check `SENTRY_AUTH_TOKEN` is set; run `next build` and look for "Source Maps" in build output        |
| `onRequestError` not firing                  | SDK version < 8.28.0                              | Upgrade: `npm install @sentry/nextjs@latest`                                                         |
| Edge runtime errors missing                  | `sentry.edge.config.ts` not loaded                | Verify `instrumentation.ts` imports it when `NEXT_RUNTIME === "edge"`                                |
| Tunnel route returns 404                     | `tunnelRoute` set but Next.js route missing       | The plugin creates it automatically; check you ran `next build` after adding `tunnelRoute`           |
| `withSentryConfig` tree-shaking breaks build | Turbopack in use                                  | Tree-shaking options only work with webpack; remove `webpack.treeshake` options when using Turbopack |
| `global-error.tsx` not catching errors       | Missing `"use client"` directive                  | Add `"use client"` as the very first line of `global-error.tsx`                                      |
| Session Replay not recording                 | `replayIntegration()` missing from client init    | Add `Sentry.replayIntegration()` to `integrations` in `instrumentation-client.ts`                    |
