Installation

Installing component via NPM

npm install ng-chat

Import the NgChatModule on your AppModule (EG: app.module.ts):

  ],

})
export class AppModule { }

Add the component directive in your AppComponent template:

  templateUrl: './app.component.html',

})
export class AppComponent {
  title = 'app';
  userId = 999;
 
  public adapter: ChatAdapter = new MyAdapter();
}
