What are class decorators?

Answer»

Class Decorators are the highest-level decorators that determine the purpose of the classes. They indicate to Angular that a specific class is a component or module. And the decorator enables us to declare this effect without having to write any code within the class.

Example:

import { NgModule, Component } from '@angular/core'; 
@Component({ 
selector: 'class-component', 
template: '<div> This is a class component ! </div>', 
}) 
export class ClassComponent { 
constructor() { 
   console.log('This is a class component!'); 
 } 
} 
@NgModule({ 
imports: [], 
declarations: [], 
}) 
export class ClassModule { 
constructor() { 
   console.log('This is a class module!'); 
 } 
}

It is a component or module in which no code in the class is required to tell Angular. We only need to design it, and Angular will take care of the rest.
