How to list every public workspace with Yarn 2+?

I'm trying to recreate lerna's list functionality with Yarn 2, I need to get a list of every public package's name in the workspace. yarn workspaces list can list all the packages on the workplace, but it returns every package, private included.

Also I need the result in a parseable format, e.g. JSON, or just a plain output with some line breaks.

Solution

  • Turn out its quite tricky, but doable:

    yarn constraints query "workspace(Cwd), \+ workspace_field(Cwd, 'private', true), workspace_ident(Cwd, Ident)" --json

    This will give you an NDJSON stream like this:

    {"Cwd":"packages/yarnpkg-sdks","Ident":"@yarnpkg/sdks"}
{"Cwd":"packages/yarnpkg-shell","Ident":"@yarnpkg/shell"}
