yarn workspaces focus

This command will run an install as if the specified workspaces (and all other workspaces they depend on) were the only ones in the project. If no workspaces are explicitly listed, the active one will be assumed.

Note that this command is only very moderately useful when using zero-installs, since the cache will contain all the packages anyway - meaning that the only difference between a full install and a focused install would just be a few extra lines in the .pnp.cjs file, at the cost of introducing an extra complexity.

If the -A,--all flag is set, the entire project will be installed. Combine with --production to replicate the old yarn install --production.

Options

--all	Install all workspaces in the project
