What problem does it solve? Deploying an Expo web app and its server-side API routes requires managing exports, environment secrets, custom domains, and edge-runtime constraints, which is error-prone without a clear workflow. ## Core Features & Use Cases - Web and API Deployment: Export the web bundle with npx expo export -p web and ship it with eas deploy for production or PR preview URLs. - API Route Authoring: Create +api.ts handlers in the app directory supporting GET, POST, PUT, DELETE, dynamic routes, query parameters, headers, and CORS. - Edge Runtime Guidance: Work within Cloudflare Workers limitations using Web APIs and cloud databases like Turso, D1, or Supabase. - Use Case: You built an Expo Router app with a /api/users endpoint that proxies a third-party API using a secret key. Use this Skill to author the route, set the secret with eas env:create, and deploy both the site and API to production. ## Quick Start Use the eas-hosting skill to deploy my Expo web app and its API routes to EAS Hosting production.
