Sentry React Native SDK

Opinionated wizard that scans your React Native or Expo project and guides you through complete Sentry setup — error monitoring, tracing, profiling, session replay, logging, and more.

Invoke This Skill When

• User asks to "add Sentry to React Native" or "set up Sentry" in an RN or Expo app
• User wants error monitoring, tracing, profiling, session replay, or logging in React Native
• User mentions @sentry/react-native, mobile error tracking, or Sentry for Expo
• User wants to monitor native crashes, ANRs, or app hangs on iOS/Android

Note: SDK versions and APIs below reflect current Sentry docs at time of writing (@sentry/react-native ≥6.0.0, minimum recommended ≥8.0.0). Always verify against docs.sentry.io/platforms/react-native/ before implementing.

Phase 1: Detect

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

# Detect project type and existing Sentry
cat package.json | grep -E '"(react-native|expo|@expo|@sentry/react-native|sentry-expo)"'

# Distinguish Expo managed vs bare vs vanilla RN
ls app.json app.config.js app.config.ts 2>/dev/null
cat app.json 2>/dev/null | python3 -c "import sys,json; d=json.load(sys.stdin); print('Expo managed' if 'expo' in d else 'Bare/Vanilla')" 2>/dev/null

# Check Expo SDK version (important: Expo SDK 50+ required for @sentry/react-native)
cat package.json | grep '"expo"'

# Detect navigation library
grep -E '"(@react-navigation/native|react-native-navigation)"' package.json

# Detect state management (Redux → breadcrumb integration available)
grep -E '"(redux|@reduxjs/toolkit|zustand|mobx)"' package.json

# Check for existing Sentry initialization
grep -r "Sentry.init" src/ app/ App.tsx App.js _layout.tsx 2>/dev/null | head -5

# Detect Hermes (affects source map handling)
cat android/app/build.gradle 2>/dev/null | grep -i hermes
cat ios/Podfile 2>/dev/null | grep -i hermes

# Detect Expo Router
ls app/_layout.tsx app/_layout.js 2>/dev/null

# Detect backend for cross-link
ls backend/ server/ api/ 2>/dev/null
find . -maxdepth 3 \( -name "go.mod" -o -name "requirements.txt" -o -name "Gemfile" -o -name "package.json" \) 2>/dev/null | grep -v node_modules | head -10
