What problem does it solve? Deploying an Expo web app and its server-side API routes requires configuring hosting, environment secrets, custom domains, and understanding edge runtime constraints. This Skill guides the full workflow of exporting the web bundle, deploying to EAS Hosting, and authoring Expo Router API routes that run on Cloudflare Workers. ## Core Features & Use Cases - Web and API Deployment: Export the web bundle with npx expo export -p web and deploy production or PR preview URLs with eas deploy. - API Route Authoring: Create +api.ts handlers with HTTP methods, dynamic routes, request parsing, CORS, and error handling. - Runtime Guidance: Work within Cloudflare Workers limitations using Web APIs, edge-compatible databases like Turso or D1, and EAS environment secrets. - Use Case: You built an Expo app with a web frontend and need a /api/ai endpoint that calls OpenAI with a secret key. Use this Skill to author the route, store the key 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.
