What problem does it solve? Shipping a mobile app to production involves juggling build profiles, store credentials, version numbers, and store listing metadata across Apple and Google. This Skill guides the entire EAS build-and-submit pipeline so Expo apps reach the App Store, Play Store, and TestFlight without manual console work. ## Core Features & Use Cases - Production Builds & Submission: Run eas build and eas submit with production profiles for iOS and Android, including one-command TestFlight releases via npx testflight. - Store Configuration: Configure eas.json build and submit profiles, Apple App Store Connect API keys, Google Play service accounts, release tracks, and staged rollouts. - Version & Metadata Management: Manage remote app versions and build numbers with autoIncrement, and maintain App Store metadata, keywords, and ASO via store.config.json with eas metadata:push. - Use Case: You are ready to ship your Expo app. Use this Skill to configure eas.json, build production binaries for both platforms, submit to TestFlight for beta testing, then promote to the App Store and Play Store with localized metadata. ## Quick Start Ask the assistant to build your Expo app for production and submit it to TestFlight and the Google Play internal track using EAS.
