ngx-b-signalr v1.0.6

NGX-B Signal-R

Installation

1. Dependency: Before add the lib to your project, install de signalr official lib (click here or):

   ```
   npm install @microsoft/signalr@6.0.5
   ```
   
   You can install the library using:
   
   **npm:**
   ```
   npm install ngx-b-signalr
   ```

2. Add the BSignalrModule to your app.module.ts and import your environment variable:

   @NgModule({
       declarations: [
           ...
       ],
       imports: [
           ...
           BSignalrModule.forRoot(environment),
       ],
   })

3. Implement the interface SignalRConfig to environment.ts and set the url for you signalr server:

   export  const  environment: SignalRConfig | any  = {
       ...,
       signalrEndpoint:  "http://localhost:7001/hub"
   }

4. Call startup method in your app.component.ts or in application initializer:

   export  class  AppComponent {
       title  =  '...';
       
       constructor(private  signalRService : SignalRService) {
           this.signalRService.connect();
       }
   }

Getting Started

The library provides an easy interface to connect to your Signal-R server.

Create a subscription:

The subscription is a way to receive messages from a specified room.

1. Instance a new SignalRSubscription and listen for a message room:

   import { SignalRService, SignalRSubscription } from  'ngx-b-signalr';
   
   ...
   
   subscription! : SignalRSubscription<CollectorState>;
   
   constructor(private  signalRService : SignalRService) {
       this.subscription = this.signalRService.buildSubscription(`ROOM`);
       this.subscription.OnMessageReceived$.subscribe(x  => {
           console.log('Response: ', x);
       }
   }

2. Always call .destroy() on your OnDestroy() method to unsubscribe:

   ngOnDestroy():  void {
       this.subscription.destroy();
   }

Compatibility

Tip: The lib was not tested in previous versions of angular, fell free to give us a feedback ;)
