SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provide secure server-side endpoints for Expo Router and EAS Hosting to keep API keys and other secrets off the client, perform protected database operations, proxy third-party APIs, validate input, receive webhooks, and offload heavy computation from mobile devices.

Core Features & Use Cases

  • Server-side secrets — Safely use environment variables for API keys and credentials without exposing them to the client.
  • HTTP method handlers & dynamic routes — Implement GET, POST, PUT, DELETE and parameterized routes for RESTful endpoints.
  • Proxying & webhooks — Hide third-party API keys when calling external services and receive webhook callbacks securely.
  • Runtime-aware deployment — Guidance for deploying to EAS Hosting on Cloudflare Workers with considerations for limited Node APIs, timeouts, and available Web APIs.
  • Developer workflows — Local testing, CORS configuration for web clients, error handling patterns, and recommended database options for edge environments.

Quick Start

Start the development server and call the /api/hello endpoint to verify API route behavior and environment variable handling.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I hide API keys in Expo Router using server-side API routes?▼

To hide API keys in Expo Router, use server-side API routes to securely access environment variables. This keeps credentials off the mobile client while enabling protected database operations and third-party API proxying.

Can I use Expo API routes with EAS Hosting on Cloudflare Workers?▼

Yes, you can deploy Expo API routes to EAS Hosting on Cloudflare Workers. The implementation provides runtime-aware guidance for handling limited Node APIs, execution timeouts, and available Web APIs within the edge environment.

How do I handle CORS and HTTP methods in Expo API routes?▼

Handle CORS and HTTP methods in Expo API routes by configuring standard GET, POST, PUT, and DELETE handlers with built-in CORS support. This enables RESTful endpoints and dynamic parameterized routes for web clients.

How do I receive webhooks and proxy third-party APIs in an Expo backend?▼

Receive webhooks and proxy third-party APIs in an Expo backend by configuring server-side routes to intercept external callbacks and forward requests. This securely hides third-party API keys during server-side validation and proxying.

What are the limitations of using Cloudflare Workers runtime for Expo API routes?▼

Limitations of using Cloudflare Workers for Expo API routes include restricted Node APIs, execution timeouts, and dependency on available Web APIs. The implementation provides runtime-aware guidance to navigate these edge environment constraints.
