Compatibility issue with PNPM package manager in 2.10.0

[drochgenius]

We are using pnpm package manager in our monorepo, in which we have many Visual Studio Code extensions.

Up until version 2.10.0, we were able to build the plugins with the --yarn option, but from version 2.10.0 it complains the yarn.lock is not available due to this change: d68e2f7.

Without the --yarn option, the plugins do not build in the monorepo context.

Could you please explain why this change was made, and advise how we could adapt our codebase?

Thanks

@drochgenius PNPM support is pending: #421, we never implemented it.

Looking at d68e2f7, the only conclusion I can draw is that using --yarn in a workspace without yarn.lock was simply a way not to do any dependency analysis whatsoever. While this (kind of) worked for you, it wasn't intended behavior. d68e2f7 is still a correct change. Very likely you've been shipping your extension with dev dependencies.

In your workspace, where do node_modules live? Do you have a repo I can look at?

Thanks @joaomoreno for your response.

In out monorepo, the node_modules is at the root, that is 2 levels above the vscode plugin.

/node_modules/
/plugins/my-vs-code-plugin/

We switched from yarn to pnpm about 6 months ago, and it's been a very positive change for us, so I'm really looking forward tovsce supporting pnpm.

In the meantime, we have fixed the version to vsce@2.9.3 and continue using the --yarn option.

Just curious... when you run vsce ls do any node modules appear in that list?

[drochgenius]

I must to apply the --yarn flag, or else vsce ls outputs a bunch of missing package errors.
Now when I do run this command: pnpm exec vsce ls --yarn, I don't see any node modules in the list.
I just see a list of files that are local to my VS Code extension.

This is with vsce@2.9.3

[joaomoreno]

So your extension doesn't really depend on any node modules to work, correct? If so, you should not be using --yarn at all... you should be using --no-dependencies: this will skip dependency analysis altogether. Can you try?

[drochgenius]

Thanks @joaomoreno ,

Yes it works perfectly if I use the --no-dependencies flag instead of --yarn with vsce@2.10.0.
Indeed, I don't have external dependencies because I first bundle the extension using webpack, so when I reach the packaging step with vsce all my external dependencies are already resolved in the bundle.

I now understand I was not using vsce correctly for my setup.
Thanks very much for your help, I think this issue can now be closed.

Just to clarify because I spent way too much time on this matter 😅:

Both vsce package and publish have a bundle step (not entirely sure by what it's powered or how it decides things), if, like IMHO you should, you handle bundling deps as part of your build process append --no-dependencies.

AFAIK @drochgenius your workflow was actually right, since I'm pretty sure you are handling deps bundling as part of your monorepo
