npm (v7.18.+) install, --workspaces flag needed?

If I have a project with workspaces and use npm install on the root folder, do I need the --workspaces flag to install all workspaces, or is it used automatically?

It looks to me like npm install already does this automatically.

Yes you're right, npm install will install workspaces by default.
