FAQPage Schema
How do I test custom native modules in React Native with Expo?▼

To test custom native modules in React Native with Expo, you need an Expo development client. It bridges the gap between Expo Go and native code testing by allowing you to run a local development build with live reload on devices and simulators.

How do I build and distribute an Expo dev client for TestFlight?▼

You can build and distribute an Expo dev client for TestFlight by configuring EAS, flagging the build as a development client, and following the documented EAS submission flow to distribute the app for beta testing.

When do I need a development client instead of Expo Go?▼

You need a development client instead of Expo Go when your React Native project includes custom native modules, widgets, or dev extensions. Expo Go cannot run custom native code, so a local development client is required for testing these changes.

Can I use EAS to run local development builds for testing native code changes?▼

Yes, you can use EAS to generate a development client for local testing. This allows you to run the build on your device or simulator with live reload to quickly iterate on native code changes.

What is the best way to iterate on React Native widgets using Expo?▼

The best way to iterate on React Native widgets using Expo is creating a development client via EAS. This enables local testing with live reload, allowing you to see native code updates instantly without rebuilding the entire app.
