SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Expo apps often require server-side API routes to handle secrets, data validation, and proxying requests. This Skill provides a structured approach to building, testing, and deploying API routes within the Expo Router ecosystem on EAS Hosting, enabling secure server operations without exposing credentials to the client.

Core Features & Use Cases

  • API Route structure: Organize server endpoints under app/api with +api.ts conventions for deterministic routing.
  • Security & Validation: Manage server-side secrets, validate input, and handle errors with robust patterns.
  • Deployment & hosting: End-to-end guidance for local testing and deploying API routes to EAS Hosting (Cloudflare Workers) with environment variables and CORS considerations.
  • Dynamic Routing & Proxies: Support dynamic routes, middleware-like patterns, and proxy external services when needed.

Quick Start

Start by creating a new API route under app/api/hello+api.ts and implement a simple GET handler.

FAQPage Schema
How do I create server-side API routes in Expo Router?▼

Server-side secrets in Expo API routes are managed through environment variables configured during local testing and EAS Hosting deployment, ensuring credentials remain on the server and are never exposed to the client bundle.

Can I deploy Expo Router API routes to Cloudflare Workers?▼

Dynamic routing in Expo API routes is supported through structured file conventions under app/api, enabling middleware-like patterns and proxying external services when needed for complex request handling.

How do I validate input and manage errors in Expo API routes?▼

Input validation and error handling in Expo API routes use robust server-side patterns within the +api.ts files, ensuring requests are securely processed before executing server logic or returning responses.

Do I need TypeScript to build Expo Router API routes?▼

TypeScript typing is supported and utilized for Expo Router API routes to enforce type safety, satisfying production requirements for secure server operations and deterministic routing structure.

What are the limitations of hosting Expo API routes on EAS?▼

When hosting Expo API routes on EAS, limitations center on environment variable configurations and CORS considerations, requiring careful setup to maintain secure server operations and external service proxying.
