$page.query not available in production mode

[benmccann]

Describe the bug

It appears that, at least for adapter-static, $page.query is not available in production mode

Originally reported by @Abarnob in svelte-society/sveltesociety.dev#108

Reproduction

git clone [email protected]:svelte-society/sveltesociety.dev.git
cd sveltesociety.dev
git checkout staging
npm install
npm run build
cd build
python -m http.server 3000

If you navigate to http://localhost:3000/help/submitting?type=tool then the query parameter is ignored and the dropdown in not correctly populated. It works in dev mode

Is this the essentially the same as #1825/#2262, which were working-as-designed?

[benmccann]

Ah, yes, you're right. It's really not obvious 😄 #2363 would solve this so that users can't make that mistake

Here is a potential workaround client-side only :

// import { page } from '$app/stores';
import { browser } from '$app/env';

export let param /* = $page.query.get('param') */;

$: {
	if (browser) {
		const urlParams = new URLSearchParams(window.location.search);
		param = urlParams.get('param');
	}
}

@benmccann Can we close this in favor of #2361? It doesn't sound to me like there's anything else going on here.
