ADDAPPTABLES ng-signal-r is a library for angular, this library is an adapter for @addapptables/ng-web-socket
Getting Started
To get started, let's install the package through npm:
Choose the version corresponding to your Angular version:
Angular | @addapptables/ng-signal-r ----------- | ------------------- 8 | 2.x 7 | 1.x
npm i @addapptables/ng-signal-r @addapptables/ng-web-socket @aspnet/signalr --S
How to use
Create a websocket service
// gateway with params
@WebSocketGateway<IHttpConnectionOptions>({
url: 'http://localhost:22721/signalr-hub',
autoConnect: true,
options: {
transport: HttpTransportType.WebSockets,
skipNegotiation: true,
logger: LogLevel.Information
}
})
export class WebSocketService {
// web socket connection
@WebSocketServer()
server: HubConnection;
// subscribe event
@Subscribe('news')
connectedUsers(data: any) {
console.log(data);
this.server.emit('my other event', { my: 'data' });
}
// emit events
sendMessage() {
this.server.emit('my other event', { my: 'data' });
}
}
import adapter and WebSocketService into the module
import { NgWebSocketModule } from '@addapptables/ng-web-socket';
import { SignalRAdapter } from '@addapptables/ng-signal-r';
@NgModule({
imports: [
...,
NgWebSocketModule.forRoot(SignalRAdapter, [WebSocketService, /* other services socket here*/]),
/*
Or
NgWebSocketModule.forRoot(SignalRAdapter, [])
Adapter is required
*/
]
})
export class AppModule { }
for child modules
import { NgWebSocketModule } from '@addapptables/ng-web-socket';
@NgModule({
imports: [
...,
NgWebSocketModule.forFeature([WebSocketService, /* other services socket here*/])
]
})
export class AppModule { }
If you require a service to obtain the url, you can do the following
// gateway with params
@WebSocketGateway<IHttpConnectionOptions>({
autoConnect: false,
options: {
transport: HttpTransportType.WebSockets,
skipNegotiation: true,
logger: LogLevel.Information
}
})
export class WebSocketService implements ISocketWithOptions<IHttpConnectionOptions> {
// web socket connection
@WebSocketServer()
server: HubConnection;
constructor(
@Inject(API_BASE_URL) private _baseUrl: string,
private _managerSocketAdapter: ManagerSocketAdapter
) { }
//build options for websocket
withOptions(): WebSocketOptions<IHttpConnectionOptions> {
const token = '123';
const url = this._baseUrl + '?token=' + token;
return {
url
};
}
connect() {
this._managerSocketAdapter.connect(this);
}
// subscribe event
@Subscribe('news')
connectedUsers(data: any) {
console.log(data);
this.server.emit('my other event', { my: 'data' });
}
// emit events
sendMessage() {
this.server.emit('my other event', { my: 'data' });
}
}
Inject websocket into the component
@Component({
...
})
export class YourComponent implements OnInit {
constructor(
public _webSocketService: WebSocketService
) {
}
ngOnInit() {
this._webSocketService.connect();
}
}
