# library

Create an Angular library

## Usage

```bash
ng generate library ...
```

```bash
ng g lib ... # same
```

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

You can specify the collection explicitly as follows:

```bash
ng g @nrwl/angular:library ...
```

Show what will be generated without writing to disk:

```bash
ng g library ... --dry-run
```
