FAQPage Schema
How do I create server-side API routes in Expo Router to protect secrets?

Expo API routes let you define server-side endpoints within app/api using a +api.ts suffix to protect secrets and manage data operations without exposing keys to clients. This keeps credentials secure on the server.

Can I use Expo API routes with EAS Hosting for my mobile app backend?

Yes, Expo API routes support deployment via EAS Hosting on Cloudflare Workers, enabling scalable serverless backends for mobile apps. This provides a secure layer to centralize business logic across clients.

What HTTP methods and dynamic routes does Expo Router support for server endpoints?

Expo Router supports defining handlers for various HTTP methods and dynamic routes within your API endpoints. You can validate data, handle webhooks, and proxy external services directly from these route files.

Why should I avoid direct client calls to secrets in my Expo application?

Direct client calls expose credentials to users, so Expo API routes centralize server-side operations to protect secrets. This ensures sensitive keys and environment variables remain securely on the backend.

How do I validate inputs and handle webhooks using Expo server routes?

You validate inputs and handle webhooks by implementing specific HTTP method handlers inside your +api.ts route files. This centralizes business logic and data validation on the server before processing requests.

Does Expo API routes require TypeScript for defining serverless endpoints?

TypeScript is supported for defining serverless endpoints in Expo API routes, ensuring type safety for your server-side logic and environment variables. This helps manage data operations securely within the Expo Router.
