List The Installed Version Of A Specific Package

pnpm is a Node-ecosystem package manager with first-class support for monorepos. In a monorepo with many apps and packages that each have their own package.json file, it can be tricky to know what version of a package is installed for a specific app or package.

The pnpm list command can help with that. First navigate to a specific app or package whose dependencies you want to know about. Then run a command like the following, replacing @trpc/next with your package of interest.

$ pnpm list '@trpc/next'
Legend: production dependency, optional only, dev only

epic-react /Users/jbranchaud/code/clients/egghead/products/apps/epic-react

dependencies:
@trpc/next 10.7.0

It tells you the exact version of that dependency that is isntalled for the current app/package.

This command can also be used with regex. Let's say you want to know about all next-related dependencies. You could do the following:

$ pnpm list '*next*'
