What are the class decorators in Angular?

A class decorator is a decorator that appears immediately before a class definition, which declares the class to be of the given type, and provides metadata suitable to the type

The following list of decorators comes under class decorators,

1. @Component()
2. @Directive()
3. @Pipe()
4. @Injectable()
5. @NgModule()

Practical Code Example

// Class Decorators in Angular:
@Component({ selector: 'app-root', template: '' }) export class AppComp {}
@Directive({ selector: '[appBold]' }) export class BoldDir {}
@Pipe({ name: 'truncate' }) export class TruncPipe {}
@Injectable({ providedIn: 'root' }) export class ApiService {}
