Sentry React Router Framework SDK

Opinionated wizard that scans your React Router Framework project and guides you through complete Sentry setup across client and server entry points.

Invoke This Skill When

• User asks to "add Sentry to React Router Framework" or "set up Sentry in React Router v7 framework mode"
• User wants to install or configure @sentry/react-router
• User uses React Router framework entry files (entry.client.tsx, entry.server.tsx) and wants tracing/error capture
• User asks about reactRouterTracingIntegration, sentryOnError, createSentryHandleRequest, or React Router wizard setup

> Important: This SDK is currently beta. > For React Router non-framework/data/declarative mode (v5/v6/v7), use sentry-react-sdk with @sentry/react integrations instead.

Phase 1: Detect

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

bash
# Detect React Router Framework indicators and versions
cat package.json | grep -E '"react-router"|"@react-router/"|"react-router-dev"|"react-router-serve"'

# Detect Sentry package choice
cat package.json | grep -E '"@sentry/react-router"|"@sentry/react"|"@sentry/profiling-node"'

# Check entry point visibility and server instrumentation files
ls entry.client.tsx entry.server.tsx instrument.server.mjs react-router.config.ts vite.config.ts 2>/dev/null

# Check if React Router files are still hidden (framework mode helper command available)
cat package.json | grep -E '"reveal"|react-router'

# Detect runtime startup scripts and import strategy
cat package.json | grep -E '"dev"|"start"|NODE_OPTIONS|--import'

# Detect optional logging/profile-related dependencies
cat package.json | grep -E '"pino"|"winston"|"@sentry/profiling-node"'

# Detect companion backend directories
ls ../backend ../server ../api 2>/dev/null
cat ../go.mod ../requirements.txt ../Gemfile ../pom.xml 2>/dev/null | head -3

What to determine:

| Question | Impact | |----------|--------| | @sentry/react-router already installed? | Skip install and move to feature setup | | Framework entry files exposed? | Need npx react-router reveal before manual config | | Using @sentry/react instead? | This is likely non-framework routing; redirect to sentry-react-sdk | | react-router.config.ts + Vite config present? | Source map upload and build-end hook setup path | | NODE_OPTIONS --import available? | Preferred server instrumentation startup path | | @sentry/profiling-node desired/available? | Enable server profiling integration | | Backend directory found? | Trigger Phase 4 cross-link suggestion |

Phase 2: Recommend

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

Recommended (core coverage):

• ✅ Error Monitoring — always; captures client and server errors with framework hooks
• ✅ Tracing — recommended baseline in framework apps with client/server request flow
• ✅ Session Replay — recommended for user-facing applications

Optional (enhanced observability):

• ⚡ Profiling — server-side profiling with @sentry/profiling-node
• ⚡ Logs — structured Sentry.logger.* ingestion and correlation
• ⚡ User Feedback — in-app feedback widget/reporting flows

Recommendation logic:

| Feature | Recommend when... | |---------|------------------| | Error Monitoring | Always — non-negotiable baseline | | Tracing | Usually yes in framework apps; route and request timing is high-value | | Session Replay | User-facing product or difficult UX debugging | | Profiling | Server performance investigations needed; Node runtime compatibility verified | | Logs | Team wants log-search and trace correlation in Sentry | | User Feedback | Product/support teams need direct in-app issue reports |

Propose: "I recommend Error Monitoring + Tracing + Session Replay first. Want me to also enable Profiling, Logs, and User Feedback?"

Phase 3: Guide

Option 1: Wizard (Recommended)

> You need to run this yourself — the wizard is interactive and may require browser login: > > bash > npx @sentry/wizard@latest -i reactRouter > > > It installs @sentry/react-router, exposes React Router entry files, creates instrumentation files, updates root error handling, configures source map upload, and adds verification examples. > > Once it finishes, continue at Verification.

If the user skips wizard setup, continue with manual setup below.

Option 2: Manual Setup

Install packages

bash
npm install @sentry/react-router --save

If profiling is needed:

bash
npm install @sentry/profiling-node --save

Expose framework entry files

bash
npx react-router reveal

Configure client in entry.client.tsx

tsx
import * as Sentry from "@sentry/react-router";
import { startTransition, StrictMode } from "react";
import { hydrateRoot } from "react-dom/client";
import { HydratedRouter } from "react-router/dom";

Sentry.init({
  dsn: "___PUBLIC_DSN___",
  sendDefaultPii: true,
  integrations: [
    Sentry.reactRouterTracingIntegration(),
    Sentry.replayIntegration(),
    Sentry.feedbackIntegration({ colorScheme: "system" }),
  ],
  enableLogs: true,
  tracesSampleRate: 1.0,
  tracePropagationTargets: [/^\//, /^https:\/\/yourserver\.io\/api/],
  replaysSessionSampleRate: 0.1,
  replaysOnErrorSampleRate: 1.0,
});

startTransition(() => {
  hydrateRoot(
    document,
    <StrictMode>
      <HydratedRouter onError={Sentry.sentryOnError} />
    </StrictMode>,
  );
});

Configure server in instrument.server.mjs

javascript
import * as Sentry from "@sentry/react-router";
import { nodeProfilingIntegration } from "@sentry/profiling-node";

Sentry.init({
  dsn: "___PUBLIC_DSN___",
  sendDefaultPii: true,
  enableLogs: true,
  integrations: [nodeProfilingIntegration()],
  tracesSampleRate: 1.0,
  profileSessionSampleRate: 1.0,
});

Wrap server handlers in entry.server.tsx

tsx
import * as Sentry from "@sentry/react-router";
import { createReadableStreamFromReadable } from "@react-router/node";
import { renderToPipeableStream } from "react-dom/server";
import { ServerRouter } from "react-router";

const handleRequest = Sentry.createSentryHandleRequest({
  ServerRouter,
  renderToPipeableStream,
  createReadableStreamFromReadable,
});

export default handleRequest;

export const handleError = Sentry.createSentryHandleError({
  logErrors: false,
});

For custom server logic, use wrapSentryHandleRequest, getMetaTagTransformer, and manual Sentry.captureException in your custom handleError.

Load server instrumentation on startup

Prefer NODE_OPTIONS --import:

json
{
  "scripts": {
    "dev": "NODE_OPTIONS='--import ./instrument.server.mjs' react-router dev",
    "start": "NODE_OPTIONS='--import ./instrument.server.mjs' react-router-serve ./build/server/index.js"
  }
}

Fallback for platforms where runtime flags are restricted:

tsx
import "./instrument.server.mjs";

This direct-import method can result in incomplete auto-instrumentation compared to --import.

Configure source maps

vite.config.ts:

typescript
import { reactRouter } from "@react-router/dev/vite";
import {
  sentryReactRouter,
  type SentryReactRouterBuildOptions,
} from "@sentry/react-router";
import { defineConfig } from "vite";

const sentryConfig: SentryReactRouterBuildOptions = {
  org: "___ORG_SLUG___",
  project: "___PROJECT_SLUG___",
  authToken: process.env.SENTRY_AUTH_TOKEN,
};

export default defineConfig((config) => {
  return {
    plugins: [reactRouter(), sentryReactRouter(sentryConfig, config)],
  };
});

react-router.config.ts:

typescript
import type { Config } from "@react-router/dev/config";
import { sentryOnBuildEnd } from "@sentry/react-router";

export default {
  ssr: true,
  buildEnd: async ({ viteConfig, reactRouterConfig, buildManifest }) => {
    await sentryOnBuildEnd({ viteConfig, reactRouterConfig, buildManifest });
  },
} satisfies Config;

Configuration Reference

Key Sentry.init() options

| Option | Type | Default | Notes | |--------|------|---------|-------| | dsn | string | — | Required; SDK disabled when empty | | sendDefaultPii | boolean | false | Includes headers/IP-derived user context | | integrations | Integration[] | SDK defaults | Add tracing/replay/feedback/profiling integrations | | enableLogs | boolean | false | Enables Sentry.logger.* ingestion | | tracesSampleRate | number | — | Usually 1.0 in testing, lower in production | | tracePropagationTargets | (string|RegExp)[] | SDK defaults | URLs that receive tracing headers | | replaysSessionSampleRate | number | — | Fraction of all sessions recorded | | replaysOnErrorSampleRate | number | — | Fraction of error sessions recorded | | profileSessionSampleRate | number | — | Fraction of transactions profiled (server profiling) | | tunnel | string | — | Optional ad-blocker bypass endpoint | | debug | boolean | false | Verbose SDK diagnostics |

Framework-specific APIs

| API | Purpose | |-----|---------| | reactRouterTracingIntegration() | Client-side tracing integration for framework mode | | sentryOnError | Hooks into React Router HydratedRouter error reporting | | createSentryHandleRequest(...) | Server request wrapper for framework entry server | | createSentryHandleError(...) | Server error handler wrapper | | wrapServerLoader(...) / wrapServerAction(...) | Manual wrapping for server loaders/actions | | sentryReactRouter(...) | Vite plugin for source maps/build integration | | sentryOnBuildEnd(...) | React Router build-end hook for source map processing |

Verification

Wizard-generated path

If wizard examples were generated, open /sentry-example-page and trigger test actions.

Manual error test

tsx
export async function loader() {
  throw new Error("My first Sentry error!");
}

Manual tracing test

tsx
import * as Sentry from "@sentry/react-router";

export async function loader() {
  return Sentry.startSpan(
    { op: "test", name: "My First Test Transaction" },
    () => {
      throw new Error("My first Sentry error!");
    },
  );
}

Logs test

javascript
Sentry.logger.info("User example action completed");
Sentry.logger.warn("Slow operation detected", { operation: "data_fetch", duration: 3500 });
Sentry.logger.error("Validation failed", { field: "email", reason: "Invalid email" });

Confirm in Sentry:

• Issues: errors appear
• Traces: transaction/span data appears
• Profiles: profiles appear when profiling enabled
• Replays: replay entries appear when enabled
• Logs: log events appear when enableLogs: true
• User Feedback: submissions appear when feedback enabled

Phase 4: Cross-Link

After completing React Router Framework setup:

1. Check whether the app is actually non-framework routing (v5/v6/v7 data/declarative with @sentry/react).
2. If yes, redirect to sentry-react-sdk for non-framework routing integrations.

Then check companion backend coverage:

bash
ls ../backend ../server ../api ../go ../python 2>/dev/null
cat ../go.mod ../requirements.txt ../pyproject.toml ../Gemfile ../pom.xml 2>/dev/null | head -5

| Backend detected | Suggest skill | |------------------|--------------| | Go | sentry-go-sdk | | Python | sentry-python-sdk | | Ruby | sentry-ruby-sdk | | Node backend services | sentry-node-sdk | | Java services | Use @sentry/java docs |

Troubleshooting

| Issue | Solution | |-------|----------| | entry.client.tsx / entry.server.tsx missing | Run npx react-router reveal first | | Client errors missing | Ensure HydratedRouter includes onError={Sentry.sentryOnError} | | Server errors missing | Use createSentryHandleRequest and createSentryHandleError wrappers | | Custom server handlers bypass Sentry | Use wrapSentryHandleRequest and manual captureException in custom handleError | | Source maps not uploaded | Verify sentryReactRouter plugin config and sentryOnBuildEnd hook | | SENTRY_AUTH_TOKEN undefined in Vite config | Load env vars in config or use .env.sentry-build-plugin | | Incomplete server auto-instrumentation | Prefer NODE_OPTIONS='--import ./instrument.server.mjs' startup | | Profiling data missing | Confirm @sentry/profiling-node installed and nodeProfilingIntegration enabled | | Running unsupported Node auto-instrumentation version | Use instrumentation API/manual wrappers as documented | | Non-framework app configured with @sentry/react-router | Switch to sentry-react-sdk + @sentry/react for v5/v6/v7 non-framework routes |
