pnpm-workspace

pnpm-workspace.yaml is the file defining all packages in a monorepo.

Note

pnpm refers to the root of the repository as the 'workspace'.

Hence why this is called pnpm-workspace.

npm refers to packages inside a monorepo as a 'workspace'.

For example (yoinked from the docs):

packages:
  # specify a package in a direct subdir of the root
  - 'my-app'
  # all packages in direct subdirs of packages/
  - 'packages/*'
  # all packages in subdirs of components/
  - 'components/**'
  # exclude packages that are inside test directories
  - '!**/test/**'
