Support for Yarn PnP

[bmulholland]

Describe the bug

When using Yarn PnP (and possibly with pnpm without some forms of hoisting?), there's no node_modules directory. In this case, the icons from an iconify pack aren't imported. With the vite example from the examples dir, with default yarn settings, I get "Internal server error: Icon mdi/alarm-off not found"

This may be an issue with a dependency (iconify?). It may also be expected behaviour -- in which case, maybe there's a less "magic" way to configure the imported icons. If so, could just document that.

I'm happy to dig into this myself, if I can get some pointers of where to look. Right now I'm not even sure if this is the right project to report this too -- a lot of magic is going on!

Reproduction

Repro'd with example from examples dir. Just take files, add yarn berry with default settings, and try yarn dev

I don't have interests in supporting PnP, nor taking the complexity. Maybe we could expose an array where you can tell explicitly what collections are available?

[bmulholland]

Yeah I was thinking of something like that. It feels like there's likely just a bit of explicit configuration that could side-step the whole problem. That would be both acceptable (to the end-user dev) and way easier to maintain (for you). I'd be happy to poke at doing something like this -- sounds like you already have an idea of what/where? Could you point me in the right direction of where that array would go?

[bmulholland]

Just to drop in my initial thought: use the customCollections code to provide an explicit mapping. I don't know if that could work?

[antfu]

Sure, feel free to send a PR and we could discuss with the implementation

[bmulholland]

I guess I buried my question. I don't know where to start with the PR :). Could you kindly point me to where the magic resolution of collections happens? Any place I could start? Context that could help me? Even a file name or a sentence or two of context?

Like I say, I don't even know if the right code is in this repository. I don't have time to wrap my head around the multiple repos involved, but can certainly start something if I know the right place to look...
