GitHub Actions Build Artifacts

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 gh or REST API.

Quick Reference

  1. Add composite actions from gha-ios-composite-action.md and gha-android-composite-action.md.
  2. Wire them into .github/workflows/mobile-build.yml from gha-workflow-and-downloads.md.
  3. Upload with actions/upload-artifact@v4 and capture artifact-id output.
  4. Download with gh run download or GET /repos/{owner}/{repo}/actions/artifacts/{artifact_id}/{archive_format}.

References

File Description
gha-ios-composite-action.md Composite action.yml for iOS simulator .app.tar.gz builds and artifact upload
gha-android-composite-action.md Composite action.yml for Android emulator .apk builds and artifact upload
gha-workflow-and-downloads.md End-to-end workflow wiring plus gh and REST download commands

Problem -> Skill Mapping

Problem Start With
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
