yarn plugin import https://raw.githubusercontent.com/andreialecu/yarn-plugin-workspace-lockfile/main/packages/plugin/bundles/%40yarnpkg/plugin-workspace-lockfile.js
yarn install
Creates a separate lockfile named yarn.lock-workspace in each workspace in a yarn 2+ project, containing only dependencies pertaining to that specific workspace.
This can be useful if you need to partition a big monorepo into smaller repos which you can share with individual developers, without giving them access to the entire code base.
You can set-up git submodules in the root monorepo, so that each workspace directory is an individual git repository.
Developers can then clone the repository they need to work on, and either rename yarn.lock-workspace to yarn.lock before installing, or they can create a .yarnrc.yml file that contains lockfileFilename: yarn.lock-workspace.
