SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Expo apps often need server-side endpoints to handle secrets, validate requests, proxy external services, and protect API keys from client exposure. This guide shows how to structure and implement API routes in the app/api directory using +api.ts files, with proper HTTP methods, request handling, and error management.

Core Features & Use Cases

  • Server-side endpoints: Implement +api.ts handlers for GET, POST, PUT, DELETE to protect secrets and perform validations.
  • Request validation & security: Validate inputs, implement simple auth checks, and handle errors gracefully on the server.
  • Deployment readiness: Prepare routes for deployment to EAS Hosting and Cloudflare Workers, including environment config and runtime constraints.

Quick Start

Create a sample API route under app/api with a +api.ts file and run the local Expo server to verify routing.

How do I build secure server-side API routes in Expo?▼

You can build secure server-side API routes in Expo by creating +api.ts files under the app/api directory to handle HTTP methods, validate requests, and protect API keys from client-side exposure.

Can I use Expo Router for dynamic API routes and request validation?▼

Yes, Expo Router supports dynamic API routes and request validation by defining GET, POST, PUT, and DELETE handlers inside +api.ts files, enabling secure server-side data processing and input validation.

Does EAS Hosting support deploying Expo API routes to Cloudflare Workers?▼

Yes, EAS Hosting supports deploying Expo API routes to Cloudflare Workers, allowing you to execute server-side endpoints with proper environment variable configuration and runtime constraints for web and mobile apps.

How do I manage secrets and environment variables in Expo API routes?▼

You manage secrets and environment variables in Expo API routes by configuring them for EAS Hosting and Cloudflare Workers, ensuring sensitive API keys remain server-side only within your +api.ts endpoint handlers.

What are the limitations of using Expo API routes for server-side logic?▼

Limitations of Expo API routes include specific runtime constraints when deploying to Cloudflare Workers via EAS Hosting, requiring careful management of environment variables, CORS, and error handling within the server-side execution environment.
