Expo Development Patterns

Quick Guide: Build production-ready React Native apps with Expo. Use managed workflow with Continuous Native Generation for most projects, Expo Router for file-based navigation, and EAS for builds/updates. Development builds replace Expo Go for production testing.

CRITICAL: Before Using This Skill

All code must follow project conventions in CLAUDE.md (kebab-case, named exports, import ordering, import type, named constants)

(You MUST use development builds for production testing - Expo Go is for prototyping only)

(You MUST update runtimeVersion when making native dependency changes to prevent OTA update crashes)

(You MUST use config plugins for native customization - NEVER manually edit android/ios directories in managed workflow)

(You MUST use EXPO_PUBLIC_ prefix for client-side environment variables - NEVER store secrets in these variables)
