Hi @dreamy imp. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Astro does not provide direct access to query parameters in the URL for static sites. This is because Astro builds a static site by default and your build does not have access to search params. Only a server can see the search params, since they are passed by the user when the user makes a request, and static sites are built ahead of time without knowing what search params a user might send.
However, if you change output: 'server' in your Astro configuration, Astro will stop stripping those values and you should be able to access the query parameters.
If you are using a JavaScript framework within Astro, like Vue, you can use window.location.href function to get params.
Here is an example of how you can get the query parameters:
let url = new URL(window.location.href);
let debug = url.searchParams.get("debug");
This will give you the value of the debug parameter from the URL.
Please note that this method is dependent on running JavaScript in the client's browser, and it won't work during the build process of a static site.
For more information, you can refer to the Astro Documentation (https://docs.astro.build/en/guides/server-side-rendering/).
