NGX Angular Loading

Credits

This project was seeded by https://github.com/darthwade/angular-loading because the author was not responding to pull requests so decided to take what they had started and update and run with it. Along the way we put some of our own opinions on it and added some tests, enough changes that it stopped being a viable PR for the original without serious breaking changes.

Migrating from angularjs dwloading

Markup:

From AngularJS

<div dwLoading="updating" [dwLoadingOptions]="spinnerConfig">

To Angular 2+

<div ngxLoading="updating" [loadingOptions]="spinnerConfig">

Installation

npm install ngx-angular-loading

Step 1. Import the 'NGXLoadingModule' module

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { NGXLoadingModule } from 'ngx-angular-loading';
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    NGXLoadingModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Step 2. Include NGXLoadingService in your component

Use the service to start and finish the different loading screens You may use $loading for legacy or rename your references to ngxLoadingService

import { Component } from '@angular/core';
import { NGXLoadingService } from 'ngx-angular-loading';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'ngx-angular-loading demo';

  isLoading = false;

  public spinnerConfig: any;

  constructor(private $loading: NGXLoadingService) {
    this.spinnerConfig = {
      text: 'Loading...',
      spinnerOptions: {
          color: '#0078D2'
      }
    };
  }

  public onButtonClick() {
    this.isLoading
      ? this.$loading.finish('updating')
      : this.$loading.start('updating');

    this.isLoading = !this.isLoading;
  }
}
