# affected:libs

    **Deprecated:** Use `nx print-affected --type=lib ...` instead. This command will be removed in v15.

    Print libraries affected by changes

## Usage

```terminal
nx affected:libs
```

Install `nx` globally to invoke the command directly using `nx`, or use `npx nx`, `yarn nx`, or `pnpm nx`.

### Examples

Print the names of all the libs affected by changing the index.ts file:

```terminal
 nx affected:libs --files=libs/mylib/src/index.ts
```

Print the names of all the libs affected by the changes between main and HEAD (e.g., PR):

```terminal
 nx affected:libs --base=main --head=HEAD
```

Print the names of all the libs affected by the last commit on main:

```terminal
 nx affected:libs --base=main~1 --head=main
```
