SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides guidelines for creating server-side API routes within an Expo Router application, enabling secure handling of server-side secrets, database operations, and external API integrations.

Core Features & Use Cases

  • Secure Server-Side Logic: Implement logic that requires server-side secrets (API keys, database credentials) or sensitive operations.
  • API Proxies & Webhooks: Create endpoints to proxy requests to third-party services or receive webhook callbacks.
  • Use Case: You need to build a backend endpoint for your Expo app that securely calls the OpenAI API to generate text based on user prompts, without exposing your OpenAI API key to the client.

Quick Start

Use the expo-api-routes skill to create a GET endpoint at /api/hello that returns a JSON message.

FAQPage Schema
How do I build serverless API routes with Expo Router?▼

To build serverless API routes with Expo Router, you create endpoints that handle HTTP methods, parse requests, and manage environment variables for secure server-side logic. This approach enables database operations and external API integrations within your application.

How can I secure API keys in my Expo app using server-side routes?▼

To secure API keys in your Expo app, use API routes to move sensitive logic server-side. This prevents exposing secrets like OpenAI credentials to the client, allowing you to safely proxy requests to third-party services or handle webhook callbacks.

Can I deploy Expo Router API routes to EAS Hosting?▼

Yes, you can deploy Expo Router API routes to EAS Hosting. The deployment targets the Cloudflare Workers runtime, which requires addressing specific serverless environment limitations and using compatible Web APIs and database solutions for full functionality.

What are the limitations of building API routes in a serverless environment?▼

The limitations of building API routes in a serverless environment include runtime constraints on platforms like Cloudflare Workers. You must implement CORS, manage error handling, and select alternative Web APIs and database solutions designed for serverless compatibility.

Do I need a separate backend framework to handle webhooks in Expo?▼

You do not need a separate backend framework to handle webhooks in Expo. You can create dedicated API routes within Expo Router to receive webhook callbacks and proxy requests directly to third-party services on your serverless hosting platform.
