Server & Endpoints — Chapter Quiz

Question 1

1

To enable server rendering for a specific page in an otherwise static site, you…

AChange output to "server"BAdd export const prerender = false to that pageCMove it outside src/pages/DWrap it in <ServerOnly>

Hybrid mode (the default in Astro 4+) lets you pick per page. prerender = false opts a single page into server rendering.

Question 2

2

What's an Astro adapter for?

AConnecting to databasesBTargeting a specific runtime (Node, Vercel, Netlify, Cloudflare) for server modeCAdapting old class components to function componentsDAuth middleware

Adapters bundle the build correctly for the chosen runtime. Without one, server mode has nothing to deploy to.

Question 3

3

A .ts file in src/pages/ is treated as an endpoint, not a page.

TTrueFFalse

Export named HTTP methods (GET, POST, etc.) returning Response. The URL maps from the file path.

Question 4

4

To return JSON from an endpoint, the shortest is…

Areturn data;Breturn new Response(JSON.stringify(data))Creturn Response.json(data)DAstro.json(data)

Response.json(value, init?) is the standard helper. Sets content-type: application/json automatically.

Question 5

5

Where do you put code that runs before every request (auth, logging)?

Asrc/middleware.ts exporting onRequestBastro.config.mjs onBeforeRequestCA _middleware.astro file in every page folderDAn adapter setting

defineMiddleware((ctx, next) => ...) runs around every page and endpoint. Use it for auth, logging, and adding values to Astro.locals.

Question 6

6

To read a cookie value:

AAstro.cookies.get("name")?.valueBdocument.cookieCAstro.props.cookies.nameDlocalStorage.getItem("name")

Astro.cookies is the server-side cookie API. document.cookie is client-side only.

Question 7

7

A secret env var in astro:env schema is automatically prevented from being shipped to the client.

TTrueFFalse

envField.string({ context: "server", access: "secret" }) makes the value server-only. Importing it from astro:env/client is a build error.

Question 8

8

To redirect from a server page, return Astro._________("/new").

Astro.redirect(url, status?) returns a Response with a Location header. The default status is 302.
