Answer 1

This is a feature of yarn 2.x. You can read more about this in the yarn documentation at https://yarnpkg.com/features/workspaces#workspace-ranges-workspace As a snippet:

For those use cases, Yarn now supports a new resolution protocol starting from the v2: workspace:. When this protocol is used Yarn will refuse to resolve to anything else than a local workspace. This range protocol has two flavors:

• If a semver range, it will select the workspace matching the specified version.
• If a project-relative path, it will select the workspace that match this path (experimental).

Answer 2

you could check about this dependency via using this command

yarn why <dependency-name>
