@nrwl/js:library

Create a TypeScript Library.

Examples

Generate a library named mylib and put it under a directory named myapp (libs/myapp/mylib)

npx nx g lib mylib --directory=myapp

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/js:library ...

Show what will be generated without writing to disk:

nx g library ... --dry-run
