I'm unable to access the query parameters of an astro file.

Given the url http://localhost:3000/example?hello=meow:

How can I access {hello: "meow"} from within the example.astro file?

• Does this answer your question? How to get the querystring parameters with Astro – BadPiggie Commented Aug 17, 2022 at 4:53
• @BadPiggie nope this is specifically using the query params on the client / front-end js. – ThomasReggi Commented Aug 17, 2022 at 14:50
• What do you mean by server side. The pages in Astro are rendered up-front and are entirely static – BadPiggie Commented Aug 17, 2022 at 15:38
• @BadPiggie there's a output: "server" mode where it does ssr instead. – ThomasReggi Commented Aug 17, 2022 at 17:55

If you're writing an API route, then you'd use a .ts or .js file [source].
In that, you can write a get method like this:

export async function get({request}) {
  // process the URL into a more usable format
  const url = new URL(request.url)
  const params = new URLSearchParams(url.search)

  // set up a response object
  const data = {
    hello: params.get('hello'),
  };

  // this will yield { hello: 'meow' } on your Astro server console
  console.log(data)
  
  // return the response
  return new Response(JSON.stringify(data), {
    status: 200
  }); }

From an .astro file you can access the url through const { url } = Astro.request; for SSR, I think. For static pages, you can do it through const url = Astro.url; [source].
