Thanks! This is looking good. Unfortunately, I'm seeing a bunch of errors :/

Not entirely sure where this is coming from

[timotius02]

Yeah it's looking like its a more complicated migration than I thought, specifically importing from node_modules. I'll be asking around the Vite discussion boards if anyone has any idea on this, but this is probably out of the scope of my current understanding.

I figured this wouldn't be an easy task. We also need to think how and if this can affect the library mode (solid-repl).
I'll put this PR in draft for the moment while you (or anyone else) investigate the matter if you don't mind :)

I would guess the issue is that vite can't statically analyze createWorker and so throws an error? Does that match what you've discovered? Also, this will not affect library mode because it only changes the /playground folder (but we should make sure it works in both dev and prod)
