Yarn 3 incompatibility

Thank you for the awesome extension! I loved using it with takeover mode, but it seems completely broken as of moving off to Yarn 3 without the node_modules folder.

First of all, it doesn’t seem to work with Yarn 3 relative path workspaces. If I have my dependency like

"gun": "workspace:packages/gun",

I can’t refer to it like

import Gun from 'gun';

And get to refer to it like

import Gun from '@/../../gun';

instead.

Even though without Volar, Yarn 3 workspaces are perfectly handled.

If I disable Take Over Mode, Vue TS checks fail completely:

Then, VSCode shows two tooltips rather than one:

If Volar has any issues that VSCode has not, these messages differ:

The upper one finds the module, the lower one (Volar) does not.

Last, but not least – Volar doesn’t import packages from .yarn:

Is Yarn 3 support not intended? I really wish it was working. Hope it’s not much of a headache to fix this. Thank you in advance!

however, in a monorepo, the same resolution errors occur. here’s a reproduction monorepo: https://github.com/adalinesimonian/volar-workspaces-pnp-test

@adalinesimonian The error I get in that repo is

Cannot find module 'vue'. Did you mean to set the 'moduleResolution' option to 'node', or to add aliases to the 'paths' option?ts(2792)

If I then set the moduleResolution to node it works.

Sorry i’m not familiar with this part, I assume that we just need setting the yarn 3 version tsdk to typescript.tsdk? I will add documentation for it. (If I’m right)

@johnsoncodehk typescript.tsdk is set by Yarn so Volar just needs to be told to use the workspace version. https://yarnpkg.com/getting-started/editor-sdks/#vscode If the workspace is trusted and typescript.tsdk is set Volar could probably pick the workspace version automatically.

which presumably doesn’t recognise ts sdk provided by yarn

@Lexpeartha it recognizes it.

here’s a reproduction repository: https://github.com/adalinesimonian/volar-pnp-test

i’ve tested this in a workspace and without and it happens either which way.
