`unstable_dev` with Cloudflare Pages

is there any way to use unstable_dev with Cloudflare Pages yet? when testing a svelte-kit build, i tried

    siteServer = await unstable_dev(path.join(SITE_DIR, ".svelte-kit", "cloudflare", "_worker.js"), {
        experimental: { enablePagesAssetsServiceBinding: {
            directory: path.join(SITE_DIR, ".svelte-kit", "cloudflare"),
        } },

    siteServer = await unstable_dev(path.join(SITE_DIR, ".svelte-kit", "cloudflare", "_worker.js"), {
        experimental: { enablePagesAssetsServiceBinding: {
            directory: path.join(SITE_DIR, ".svelte-kit", "cloudflare"),
        } },

the worker runs, but somehow it can't find the assets

pnpm wrangler pages dev is broken as hell too, why pnpm wrangler pages dev .svelte-kit/cloudflare can find the functions but when inside .svelte-kit or cloudflare, running it again with pnpm wrangler pages dev cloudflare or . can't find the functions (No functions. Shimming...)

If you’re using sveltekit, I’d recommend using its built-in dev environment (pnpm dev)

umm, i'm running those generated functions, so i'm not sure what you meant here Then there would be no platform property, no? i would like to access Cloudflare's bindings inside my load functions, or server-side in general. pnpm dev would not work because nothing is running workerd, so I wanted to build the project and test it with wrangler, just like the docs suggests:

platform.env is only available in the production build. Use wrangler to test it locally.

platform.env is only available in the production build. Use wrangler to test it locally.

basically, two things broke: 1. unstable_dev to preview a built-with-sveltekit output doesn't work 2. wrangler pages dev to preview a built-with-sveltekit output doesn't work i'm not actively working on this anymore, but that is my experience with local Cloudflare Pages

I use the miniflare api to set the bindings in the hooks file

Then miniflare v2 it is. I'm figuring out how to use miniflare v3 here, unfortunately

ajgeiss0702•11mo ago

~~i havent migrated yet, but from what i've seen the api changes are minimal? and it v3 now uses workerd BTS~~ after looking into it further, it looks like miniflare v3 removed getBindings so it's no longer possible to do that. So im stuck on miniflare v2 until either getBindings is added back, or another solution is found

I guess this might be the issue to pay attention to https://github.com/cloudflare/miniflare/issues/585
