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:

# 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:

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

npm install @sentry/react-router --save

If profiling is needed:

npm install @sentry/profiling-node --save

Expose framework entry files

npx react-router reveal

Configure client in entry.client.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 = />
    ,
  );
});

Configure server in instrument.server.mjs

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

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:

{
  "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:

import "./instrument.server.mjs";

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

Configure source maps

vite.config.ts:

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:

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;

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

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

Manual tracing test

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

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:

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
