expo-api-routes

Create Expo Router API routes by adding +api.ts files under the app/api directory to expose server-side logic. You define explicit HTTP methods like GET and POST within these files to handle incoming requests.

Yes, Expo Router API routes run server-side, allowing you to securely handle environment variables and protect API secrets from client code. This prevents exposing sensitive keys in your mobile application bundle.

Expo Router supports dynamic API routes and explicit HTTP methods including GET, POST, PUT, and DELETE. You can structure these endpoints within the app/api directory to handle various server-side operations.

Deploy Expo Router API routes using EAS Hosting or edge runtimes to expose server-side logic securely. The deployment workflow covers everything from local testing with expo serve to cloud hosting.

Configure CORS and error handling directly within your Expo API route files to manage cross-origin requests and catch server-side validation errors. This ensures robust request handling and secure responses.

No, you do not need EAS Hosting to test locally; you can test Expo API routes using expo serve. EAS Hosting is utilized later in the deployment workflow for cloud hosting and production environments.
