doesn't work with yarn pnp and esm-only modules with `import` condition

[danieltroger]

Environment

Node 21.5.0, yarn 4.0.2, macOS 14.2.1 (23C71)

Reproduction

1. git clone git@github.com:danieltroger/vinxi-repro.git
2. cd vinxi-repro
3. yarn
4. yarn build

Describe the bug

Using yarn pnp (please see https://yarnpkg.com/features/pnp) modules have to be resolved very differently, since node_modules is a concept of the past there - instead, we have de-duplicated, compressed .zip files containing our dependencies.

It seems like mlly is a re-implementation of node-js' module resolution algorithm that has never heard about yarn berry. And because yarn berry doesn't patch mlly, it just explodes when being ran with yarn berry.

Additional context

I really need yarn berrys workspace, package deduplication, patching and linking features and I updated a project to the new solid-start to which mlly is a peerDependency. I'd suggest you to just re-export the working import.meta.resolve when detecting yarn berry since this project seems redundant to me today.

Investigating such issues with higher-order metaframeworks is time-consuming. I appreciate it if you could make a minimal reproduction (with mlly utils only). closing in the meantime.

[danieltroger]

Minimal reproduction:

1. unzip mlly.zip
2. yarn
3. yarn start

Output should look like this:

[danieltroger]

Sorry I included some paths from where I reproduced the issue as part of solid-start in above, but the same error can be observed without them with just

resolvePath("vinxi/lib/invariant", {
  conditions: ["production", "node", "import", "default"]
});

[pi0]

Thanks for the reproduction.

I think same as unjs/jiti#204 (comment) for jiti, for mlly we can leverage import.meta.resolve (that yarn pnp provides) if available but only have to make sure result is not promise (older implementations do this) and if is promise, discard it for sync methods.

Faster solution for module authors is using type: "module" + "default" condition.

[bmulholland]

Hey @pi0! Hope you're well :). I'm invested in making this work, so we can use yarn pnp with unplugin-icons (see also unplugin/unplugin-icons#358).

I've made an early draft of a fix at #270. The code isn't well organized or anything; I'm looking for feedback on approach, where to put the safe resolve call, etc, before I adjust it more. Could you take a look?

I've tested the fix on both my own code and the minimal repro above; it fixes both. However, note that I tested only using a yarn patch -- I can do that once we've got the structure down, as final QA before merge.

[gnujoow]

I'm experiencing the exact same issue with TanStack Start + Yarn PnP. Here's my setup and error:

Environment:

• Node 22.13.1
• Yarn 4.9.2 (PnP mode)
• TanStack Start 1.122.1
• macOS 23.1.0

Error:

Error: ENOTDIR: not a directory, open '/...../.yarn/unplugged/nitropack-virtual-388efa10d3/node_modules/nitropack/dist/core/index.mjs/package.json'

Would love to see mlly add proper Yarn PnP support or at least detect Yarn PnP and fall back to a compatible resolution strategy.
