# library

Create a new nest library

## Usage

```bash
nx generate library ...
```

```bash
nx 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
nx g @nrwl/nest:library ...
```

Show what will be generated without writing to disk:

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

Generate libs/myapp/mylib:

```bash
nx g lib mylib --directory=myapp
```
