Call endpoints from the server

Endpoints can be used to serve many kinds of data. This recipe calls a server endpoint from a page’s component script to display a greeting, without requiring an additional fetch request.

• A project with SSR (output: ‘server’) enabled

1. Create an endpoint in a new file src/pages/api/hello.ts that returns some data:

   import type { APIRoute } from 'astro'
   
   export const GET: APIRoute = () => {
     return new Response(
       JSON.stringify({
         greeting: 'Hello',
       }),
     )
   }

2. On any Astro page, import the GET() method from the endpoint. Call it with the Astro global to provide the request context, and use the response on the page:

   ---
   import { GET } from './api/hello.ts'
   
   let response = await GET(Astro)
   const data = await response.json()
   ---
   
   <h1>{data.greeting} world!</h1>
