What problem does it solve? Shipping a React Native app to the App Store, Google Play, and web involves juggling credentials, build profiles, store metadata, and CI/CD pipelines. This Skill consolidates the entire Expo Application Services (EAS) deployment workflow into one reference so you can build, submit, and automate releases without hunting through documentation. ## Core Features & Use Cases - Store Submission: Build and submit production binaries to the iOS App Store, TestFlight, and Google Play tracks (internal, alpha, beta, production) with single EAS CLI commands. - App Store Metadata & ASO: Manage titles, keywords, descriptions, age ratings, and localized listings via store.config.json and eas metadata:push. - CI/CD Automation: Use EAS Workflows to trigger builds on push, deploy web previews for pull requests, and automate full release pipelines on version tags. - Use Case: You have finished your Expo app and need to ship it. Run npx testflight to get a beta build to testers, then use the release workflow to build and submit to both stores automatically when you push a v* tag. ## Quick Start Install the EAS CLI, run eas init to generate eas.json, then build and submit a production iOS build with eas build -p ios --profile production --submit.
