SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill solves the pain point of needing a custom Expo development client for projects that use custom native code, third-party native modules, or custom Apple targets, which cannot run on the standard Expo Go app.

Core Features & Use Cases

  • Local Dev Client Compilation: Build custom Expo development clients directly from your project's native code for local testing and debugging.
  • TestFlight Distribution: Package and distribute the compiled dev client to testers via Apple TestFlight for broader pre-release testing.
  • Use Case: If your Expo app integrates a custom native iOS SDK or uses a third-party native module unsupported by Expo Go, this Skill lets you generate a compatible dev client and share it with your team without manually configuring a full native build pipeline.

Quick Start

Ask your AI agent to use the expo-dev-client skill to build a custom development client for your Expo project with custom native iOS modules and distribute it to your test team via TestFlight.

FAQPage Schema
How do I build an Expo app with custom native modules that Expo Go cannot run?

Build a custom Expo dev client to compile projects with third-party native modules or custom native code. This generates a compatible development client for local testing without manually configuring a native build pipeline.

What is the best way to distribute an Expo development client to testers via TestFlight?

Distribute an Expo dev client via TestFlight by packaging the compiled custom client and sharing it for pre-release testing. This allows broader testing outside the standard Expo Go environment without manual native pipeline configuration.

When do I need a custom Expo dev client instead of Expo Go?

You need a custom Expo dev client when your project integrates custom native code, third-party native modules, or custom Apple targets. These features are incompatible with the standard Expo Go app and require a compiled client for testing.

Can I test an unsupported native iOS SDK in Expo without manually configuring native builds?

Yes, you can generate a compatible Expo dev client to test unsupported native iOS SDKs. This skill handles the compilation of local development clients without requiring manual native build pipeline configuration.

Does the Expo dev client support custom Apple targets for local debugging?

Yes, the custom Expo dev client supports projects with custom Apple targets. You can compile the client directly from your project's native code for local testing and debugging of native functionality.

Why does my third-party React Native module fail to run in Expo Go?

Third-party React Native modules fail in Expo Go because the standard app lacks the required custom native code. Building a custom Expo dev client resolves this by compiling the native dependencies into a dedicated development build.
