Developing Expo Apps on Limrun

Use this skill for Expo / React Native-specific setup and dev-client iteration, on iOS simulators and Android emulators. Use limrun-ios-simulator and limrun-android-emulator for command details, device interaction, screenshots, recordings, and cleanup, and the build skills (limrun-xcode, limrun-gradle) for build flag details and non-Expo workflows.

All builds and device operations must run on Limrun. Do not use local Xcode, local simulators, a local Android SDK, or local emulators; local adb is used only to talk to the remote emulator through the CLI's tunnel.

Expo Readiness

Before changing Expo dependencies or app config, check the app's Expo SDK version and use the matching Expo versioned docs.

Verify this is an Expo app:

npx expo config --type introspect --json
