Is there a way to add/remove/update dependencies for a specific workspace in a monorepo using pnpm?

[kitsune7]

Let's say I have workspace "a" and "b". If I want to install a new dependency like "lodash" to workspace a using npm, I could just run npm install lodash -w a, but in pnpm, I can't just swap out "npm install" for "pnpm add" and have it work the same way.

I know pnpm supports workspaces, but I'm not sure I understand how the --workspace option for pnpm add works. Judging from the description (and my attempts to work with it) however, it seems that the behavior is very different from the --workspace option in npm.

Am I missing something here, or do you have to run cd $PATH_TO_WORKSPACE before managing dependencies with pnpm? Is there a way to manage them from the root of the monorepo?

pnpm add lodash --filter a

That did it! Thanks @zkochan! I didn't realize that filtering could be used for workspaces!
