Can I rewrite the response URL in +page.server.ts without using redirect? Using history.replaceState() outside onMount() doesn't work

[205g0]

I could do this in the client onMount() and history.replaceState() or in +page.server.ts with redirect(). I find both options ok-ish but not optimal.

So, is there a way to rewrite the request URL when responding without using aforementioned methods?

In this context another question: Only a history.replaceState(null, '', '?someParam=0') in onMount() will add the param to the url after load. If I do this outside latter, it doesn't work or the param just shows up a millisecond and vanishes again.

I need this to work without onMount() but I guess it's not possible or do I miss something?

It's not possible to access history outside the browser context. Therefore, it's only possible in an onMount or if browser block.

What's your reason for not wanting to use redirect to append the search param to the URL?

The redirect adds another roundtrip but yeah, it would be the proper solution, also locating respective code to the right side. I want basically to rewrite searchParams, so it's not a full change of scenes.

You could also use goto("?someParam=0", { replace: true }) which is the svelte equivalent for history.replaceState.
