pnpm-workspace-graph

Visualize project relationships in your PNPM workspace

Quick start

Install the tool:

# Install the tool globally so that you can invoke it in any folder:
$ pnpm install --global pnpm-workspace-graph

Invoke the tool:

If your monorepo is using a regular PNPM workspace:

# This is the folder where you cloned your repo:
$ cd my-pnpm-monorepo

# Launch the app in your web browser
$ pnpm-workspace-graph

pnpm-workspace-graph is started at http://127.0.0.1:8188
Use Ctrl+C to close it

If your monorepo is using a Rush workspace for PNPM:

# This is the folder where you cloned your repo:
$ cd my-rush-monorepo

# Rush's pnpm-workspace.yaml is located in the "common/temp" folder.
# Run "rush install" to ensure it has been generated and is up to date.
#
# IMPORTANT: Your rush.json config file must specify useWorkspaces=true
$ rush install

# Launch the app in your web browser, specifying to use "common/temp"
$ pnpm-workspace-graph --cwd common/temp

pnpm-workspace-graph is started at http://127.0.0.1:8188
Use Ctrl+C to close it

When the app page appears in your web browser appears, click the Filter button:

Using the Settings Panel to select a subset of projects

A typical monorepo will have too many projects to be meaningfully visualized. The app allows you to use PNPM's --filter syntax to select a subset of projects that you are interested in visualizing. In separate input boxes, enter the names of the projects to be included in the view. They must be workspace projects referenced by pnpm-workspace.yaml. Specify the full name as it appears in the package.json "name" field.

To include all workspace projects that are dependencies of my-package, specify: ...my-package

To indicate all workspace projects that depend on my-package, specify: my-package...

Refer to the PNPM documentation for more information about the --filter syntax.
After you have selected a subset of projects, click the [X] to close the Settings Panel. Using the mouse, you can move the nodes to make a nice arrangement. Use the mouse wheel to zoom in or out.
