I’m not sure if I completely understand this text:

Verifies that installed modules comply with the requirements specified in package.json.

By default checks engine ranges, peer dependency ranges and installed versions and, in mono-repos using workspaces, by default checks all workspaces as well as the workspace root.

It may make sense to state requirements separately. Is this correct?

• What are the requirements? The version range specified in package.json > engines > node (details)

• Where are the requirements checked?

  • "peerDependencies"
  • "dependencies"
  • "devDependencies"
  • Monorepos via workspaces: all workspaces and workspace root

Questions:

• What exactly does “complying with the requirements” mean?
• Do the modules really have to be installed or could you also check package-lock.json?
