Generating @nx/angular:library with the name parameter fails with an error - The selector is invalid.

[Fafnur]

Current Behavior

You will get an error if you try to generate an Angular library with a name that includes a slash.

Try run:

yarn nx g @nx/angular:library libs/auth/common --name=auth/common

The issue lies with the selector name.

Error: The selector "lib-auth/common" is invalid.

Expected Behavior

It is expected that a library should be created when a slash is included in its name.

The Nx command should handle slashes by replacing them with dashes in selectors.

yarn create nx-workspace nx-20-angular-lib-generation

2. Try generate aan Angular library with a name that includes a slash: 'auth/common'
