Bun Workspaces: support for `pnpm-workspace.yaml`

[karlhorky]

What is the problem this feature would solve?

Bun Workspaces currently incompatible with installing and running package-scoped commands using the pnpm pnpm-workspace.yaml configuration file

This is a subset of the feature requests at:

• Monorepo support #533
• bun install in pnpm/yarn workspaces #2517

What is the feature you are proposing to solve the problem?

Parsing of the pnpm pnpm-workspace.yaml configuration file for workspaces for Bun Workspaces

What alternatives have you considered?

pnpm could support workspaces in package.json.

However, according to discussion and pnpm team feedback in the PR and issue below, it appears that this will probably not happen:

• feat: support workspaces field in package.json pnpm/pnpm#6881 (comment)
• Support workspaces from package.json pnpm/pnpm#2255

It still doesn't support it yet. I use mise and bun for building, and now the project is using pnpm workspace, which is painful.

Why should it?
It is pnpm thing.

@dylan-conway will work on this soon. But first, we have to write a YAML parser.

We added support for automatic pnpm-lock.yaml and pnpm-workspace.yaml migration to bun.lock and package.json in #22262. It will be included in the next release of bun later tonight (v1.2.23). You can also try it now with a canary build of bun:
