Edge support?

[imownbey]

I think right now this wont support edge based on how it is loading the WASM (and due to dependence on FS although maybe the browser version can be used?). I wondered if somehow using https://vercel.com/docs/concepts/functions/edge-functions/wasm this could be shipped to an edge function, though.

I think I tried it and it works, but I may be wrong. It doesn't use fs if it's not available.

Oh great okay will try!

let me know how it goes

mmm it did not work (at least on vercel) but I dont remember why. Will update this thread when I retry it.

It doesn't seem to be working for me due to the (node) https module:

- error ./node_modules/.pnpm/@code-hike+lighter@0.6.6/node_modules/@code-hike/lighter/dist/browser.esm.mjs:16:24
Module not found: Can't resolve 'https'

[pomber]

Strange, it should only import 'https' if 'fetch' isn't available. Conditional imports are a lie.

In cloudflare workers (and I presume Vercel as well, as they use the cloudflare runtime under the hood) you need to setup a binding to a WASM binary and then reference it.

See https://developers.cloudflare.com/workers/platform/web-assembly/javascript/

So without some bundler magic to replace the WASM import in the lighter code, I don't think it'll work right now.

v0.8.0 should fix this. At least for Vercel's edge.

I had problems with old versions of Next.js (they were ignoring the worker conditional export in lighter's package json), so try updating next.js first if you have problems.
