I've got component selector name set to kebab-case. When I run a lint, I get a bunch of errors in my components saying that... The selector of the component "AdminComponent" should be named kebab-case.

But when I go to the component definition, this is what it is:

@Component({
    selector: 'admin',
    templateUrl: 'admin.component.html',
    styleUrls: ['admin.component.css'],
    providers: []
})

The selector is only one word, and doesn't require a kebab-case selector... how can I fix this?

Answer 1

Don't know how to prevent this warning, but regarding to the official Angular Styleguide you should use your own prefix for a selector name:

https://angular.io/styleguide#02-07

Do use a custom prefix for a component selector. For example, the prefix toh represents from Tour of Heroes and the prefix admin represents an admin feature area.

Why? Prevents element name collisions with components in other apps and with native HTML elements.
