Expo + React Native skill for Claude Code — scaffolds screens, wires navigation, and respects the Expo way instead of reinventing it.

An Expo-flavored skill for Claude Code. Teaches Claude to build mobile apps the Expo way: expo-router for navigation, proper EAS config, Expo SDK modules over random npm packages. Avoids the common trap of LLMs suggesting outdated RN-CLI patterns.

使用场景

实战用法： skills

Spin up a new Expo app with tabs and auth in one session

👤 Devs starting a new mobile app who want the boring parts done ⏱ ~45 min beginner

何时使用： Day zero of a new project — you want tabs, stack, and a sign-in flow without reading three blog posts.

步骤
  1. Create the app
    Use the Expo skill. Start a new app 'TaskFlow' with expo-router, TypeScript, and the tabs template. Include a login screen with email/password.✓ 已复制
    → npx create-expo-app run, then file structure with app/(tabs)/ and app/(auth)/
  2. Add state
    Wire up Zustand for the auth store and persist to SecureStore.✓ 已复制
    → stores/auth.ts with zustand + persist middleware using expo-secure-store
  3. Test on device
    Start the dev server and give me the QR code to scan.✓ 已复制
    → npx expo start output

结果： A running app on your phone with tabs, auth, and persistence in under an hour.

注意事项
  • Claude suggests react-native-cli patterns — Explicitly say 'Expo SDK, expo-router only' in prompts
搭配使用： filesystem

Configure EAS Build for iOS and Android

👤 Teams ready to ship TestFlight / Play internal ⏱ ~30 min intermediate

何时使用： First time submitting to TestFlight/Play.

步骤
  1. Generate eas.json
    Use the Expo skill. Generate eas.json with preview (internal) and production profiles, correct bundle identifier patterns, and env var injection.✓ 已复制
    → Valid eas.json with both profiles
  2. Wire secrets
    Add my Sentry DSN and API base URL as EAS secrets for preview and production separately.✓ 已复制
    → eas secret:create commands listed
  3. Trigger the build
    Now trigger a preview build for iOS.✓ 已复制
    → eas build --profile preview --platform ios command

结果： EAS builds running, secrets managed.

注意事项
  • Committing app.json with secrets inline — Secrets go in EAS env, not app.json; let Claude use expo-constants to read them

Integrate a native module using Expo config plugins

👤 Devs adding functionality that requires native code (camera, biometrics, push) ⏱ ~20 min intermediate

何时使用： You need functionality beyond JS, but don't want to eject.

步骤
  1. Identify the right package
    Use the Expo skill. I need biometric auth. What's the right Expo SDK module and how do I configure it?✓ 已复制
    → expo-local-authentication named with config plugin entries
  2. Wire config plugin
    Add the config plugin entries and required iOS usage strings.✓ 已复制
    → app.json diff with plugins array and NSFaceIDUsageDescription

结果： Native module integrated via managed workflow.

注意事项
  • Adding raw native code and breaking managed workflow — Prefer Expo SDK modules and config plugins; eject only if truly needed

组合

与其他 MCP 搭配，撬动十倍杠杆

skills-skill-7 + filesystem

Bulk-apply Expo idioms across an existing RN project

Migrate my RN-CLI app to Expo managed workflow; point at the source tree.✓ 已复制
skills-skill-7 + git

Commit each step separately so EAS setup changes are auditable

Commit the EAS config changes as a distinct commit before adding secrets.✓ 已复制

Expo is free; EAS Build has a free tier with paid scaling
提示
Use EAS local builds during dev; cloud builds only for preview/prod.

安全

权限、密钥、影响范围

凭据存储： No direct creds; EAS secrets are managed by Expo
数据出站： None from skill itself

故障排查

常见错误与修复

Metro can't find module after install

Run npx expo install rather than npm install so SDK-compatible versions are picked

验证： npx expo-doctor
Build fails with 'unrecognized bundle identifier'

Bundle ID mismatch between app.json and Apple Developer portal; align them

Native module not found at runtime

Config plugin didn't run; rebuild with eas build or npx expo prebuild --clean
