yarn workspaces focus


To use this command, first install the workspace-tools plugin: yarn plugin import workspace-tools

Install a single workspace and its dependencies.


$> yarn workspaces focus [--json] [--production] ...


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.js file, at the cost of introducing an extra complexity.

If the --production flag is set, only regular dependencies will be installed, and dev dependencies will be omitted.

If the --json flag is set the output will follow a JSON-stream output also known as NDJSON (
