SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Astro server-side API routes and backend endpoints enable you to implement deterministic server logic, API endpoints, and SSR-backed pages within Astro projects.

Core Features & Use Cases

  • Create RESTful API routes in src/pages/api using TypeScript, exporting GET/POST/PUT/DELETE handlers.
  • Implement server-side form handling, data validation, and error handling with standard Response objects.
  • Use cases include building data APIs, webhooks, form submissions, and server-side data processing.

Quick Start

Create a new API handler under src/pages/api/hello.ts that exports a GET function returning a JSON response.

FAQPage Schema
How do I create server-side API routes in Astro?

Server-side API routes in Astro are created by adding TypeScript files under `src/pages/api/` and exporting standard HTTP method handlers like GET or POST that return Response objects.

Can I handle form submissions and data validation using Astro backend endpoints?

Astro backend endpoints handle form submissions and data validation by processing request data within POST handlers and returning standard Response objects for deterministic server logic.

Does building backend logic in Astro require server output mode?

Building backend logic in Astro requires configuring the project with `output: server` to enable server-side rendering and allow API routes to execute deterministic server logic on demand.

What's the best way to structure REST API handlers in an Astro project?

The best way to structure REST API handlers in an Astro project is using TypeScript files in `src/pages/api/`, exporting specific HTTP methods like GET, POST, PUT, and DELETE for endpoint routing.

Why does my Astro API route return a raw object instead of a valid response?

Astro API routes must return standard Response objects. Returning a raw object fails because Astro backend endpoints require a valid Response to properly format the server output.
