[fontless] Support SvelteKit

[vnphanquang]

🆒 Your use case

Thanks for the good work here! I'm a heavy Svelte/SvelteKit user, and as of 0.0.2, fontless isn't working with SvelteKit from my test here: https://github.com/vnphanquang/sveltekit-fontless-reproduction.

🆕 The solution you'd like

Would be awesome to have this working in Sveltekit, if it's even possible without any additional adapter/config. Please see the reproduction repo above for more information.

🔍 Alternatives you've considered

Right now, I'm falling back to traditional methods of loading fonts (link, font-face, manual self-hosting, etc.), i.e not using fontless

ℹ️ Additional info

Would love to dive in the vite plugin code to see if i can help but just want to report here first in case someone already has better insight. Maybe this is related to Vite environment?

I'm not familiar with fontless, but here's an example repo that uses fontaine with sveltekit: https://github.com/rodneylab/sveltekit-fontaine

this is strange as we have a sveltekit repo in our test suite. I'll have to investigate your reproduction.

update: we have a svelte app

Thanks, it's been a while. I'll check back in to see if the reproduction is still valid.

I started using fontless@0.2.1 in my SvelteKit app without issue. Thanks for this great library!

If anything, there isn't any automatic preloading, but I can comment in #650 with details.

Thanks @theetrain. I can verify that the setup now works well 🎉, as of:

{
  "@sveltejs/kit": "^2.61.1",
  "@sveltejs/vite-plugin-svelte": "^7.1.2",
  "fontless": "^0.2.1",
  "svelte": "^5.55.9",
  "vite": "^8.0.14"
}

We should close the issue?

Update: opened sveltejs/cli#1105 to allow quick setup of fontless in a Svelte/SvelteKit project.
