Overview
Reusable GitHub Actions patterns to build React Native apps for iOS simulators and Android emulators in the cloud, then publish artifacts retrievable via gh CLI or GitHub API.
When to Apply
Use this skill when:
- Creating CI workflows that build React Native simulator/emulator artifacts.
- Uploading iOS simulator and Android emulator installables from PRs or manual dispatch runs.
- Replacing local-only mobile builds with downloadable CI artifacts.
- Needing stable artifact IDs/names for scripted retrieval with
ghor REST API.
Quick Reference
- Add composite actions from gha-ios-composite-action.md and gha-android-composite-action.md.
- Wire them into
.github/workflows/mobile-build.ymlfrom gha-workflow-and-downloads.md. - Upload with
actions/upload-artifact@v4and captureartifact-idoutput. - Download with
gh run downloadorGET /repos/{owner}/{repo}/actions/artifacts/{artifact_id}/{archive_format}.

Need CI iOS simulator .app.tar.gz artifact | gha-ios-composite-action.md |
Need CI Android emulator .apk artifact | gha-android-composite-action.md |
| Need one workflow to trigger both platform jobs | gha-workflow-and-downloads.md |
| Need scripted artifact download | gha-workflow-and-downloads.md |

> upgrading-react-native
Upgrades React Native apps to newer versions by applying rn-diff-purge template diffs, updating package.json dependencies, migrating native iOS and Android configuration, resolving CocoaPods and Gradle changes, and handling breaking API updates. Use when upgrading React Native, bumping RN version, updating from RN 0.x to 0.y, or migrating Expo SDK alongside a React Native upgrade.
> react-native-brownfield-migration
Provides an incremental adoption strategy to migrate native iOS or Android apps to React Native or Expo using @callstack/react-native-brownfield for initial setup. Use when planning migration steps, packaging XCFramework/AAR artifacts, and integrating them into host apps.
> react-native-best-practices
Provides React Native performance optimization guidelines for FPS, TTI, bundle size, memory leaks, re-renders, and animations. Applies to tasks involving Hermes optimization, JS thread blocking, bridge overhead, FlashList, native modules, or debugging jank and frame drops.
