Nx comes with dedicated documentation for each framework:

@nrwl/nest:library

Create a new NestJS library.

Usage

nx generate library ...
nx g lib ... # same

By default, Nx will search for library in the default collection provisioned in workspace.json.

You can specify the collection explicitly as follows:

nx g @nrwl/nest:library ...

Show what will be generated without writing to disk:

nx g library ... --dry-run

Generate libs/myapp/mylib:

nx g lib mylib --directory=myapp
