Expo

Expo

Expo is a framework and platform for universal React Native applications. It provides a set of tools and services that make React Native development faster and easier.

Why Expo?

Expo removes much of the complexity from React Native development by providing:

  • Pre-configured build tools
  • Over-the-air updates
  • Easy access to native APIs
  • Simplified deployment process

Key Features

Expo Go

The Expo Go app allows you to preview your app on a physical device without building native code.

EAS Build

Expo Application Services (EAS) provides cloud-based build services for iOS and Android.

Expo Router

File-based routing for React Native apps, similar to Next.js.

Best Practices

  • Use Expo SDK modules instead of third-party native modules when possible
  • Implement proper error boundaries
  • Test on both iOS and Android regularly
  • Use EAS Update for quick fixes and feature flags
