Usage

1. Import QueueService interface to implement it with your custom queue service, e.g.:

import { Injectable } from '@angular/core';

@Injectable()
export class QueueService {

  constructor(private progressService: NgProgressService) { }

  /**
   * Handler for queue started event
   */
  public queueStarted(): void {
    this.progressService.start();
    
  }

  /**
   * Handler for queue finsihed event
   */
  public queueFinished(): void {
    this.progressService.done();
  }
}

2. Provide QUEUE_SERVICE, QueueModule alongside with HttpClientModule, e.g.:

import { NgModule } from '@angular/core';
import { HttpClientModule } from '@angular/common/http';
import { QueueModule, QUEUE_SERVICE } from 'ngx-request-queue';

import { QueueService } from './queue.service';

@NgModule({
    imports: [ 
      HttpClientModule,
      QueueModule
     ],
    providers: [
      { provide: QUEUE_SERVICE, useClass: QueueService },
    ]
})
export class AppModule { }
