Online demo available here

Usage

If you use SystemJS to load your files, you might have to update your config:
 System.config({  
   map: {  
     'ng2-slim-loading-bar': 'node_modules/ng2-slim-loading-bar/bundles/index.umd.js'  
   }  
 }); 

1. Update the markup

  • Import the style.css into your web page
  • Add <ng2-slim-loading-bar></ng2-slim-loading-bar> tag in template of your application component.

2. Import the SlimLoadingBarModule

    Import SlimLoadingBarModule.forRoot() in the NgModule of your application. The forRoot method is a convention for modules that provide a singleton service.

 

 
 import {BrowserModule} from "@angular/platform-browser";  
 import {NgModule} from '@angular/core';  
 import {SlimLoadingBarModule} from 'ng2-slim-loading-bar';  
 @NgModule({  
   imports: [  
     BrowserModule,  
     SlimLoadingBarModule.forRoot()  
   ],  
   bootstrap: [AppComponent]  
 })  
 export class AppModule {  
 }  
If you have multiple NgModules and you use one as a shared NgModule (that you import in all of your other NgModules), don't forget that you can use it to export the SlimLoadingBarModule that you imported in order to avoid having to import it multiple times.
 @NgModule({  
   imports: [  
     BrowserModule,  
     SlimLoadingBarModule.forRoot()  
   ],  
   exports: [BrowserModule, SlimLoadingBarModule],  
 })  
 export class SharedModule {  
 } 

3. Use the SlimLoadingBarService for your application

  • Import SlimLoadingBarService from ng2-slim-loading-bar in your application code:
<pre  style="font-family:arial;font-size:12px;border:1px dashed #CCCCCC;width:99%;height:auto;overflow:auto;background:#f0f0f0;padding:0px;color:#000000;text-align:left;line-height:20px;"><code style="color:#000000;word-wrap:normal;"> import {Component} from '@angular/core';  
 import {SlimLoadingBarService} from 'ng2-slim-loading-bar';  
 @Component({  
   selector: 'app',  
   template: `  
     &lt;div&gt;Hello world&lt;/div&gt;  
     &lt;button (click)="startLoading()"&gt;Start Loading&lt;/button&gt;  
     &lt;button (click)="stopLoading()"&gt;Stop Loading&lt;/button&gt;  
     &lt;button (click)="completeLoading()"&gt;Complete Loading&lt;/button&gt;  
     &lt;ng2-slim-loading-bar&gt;&lt;/ng2-slim-loading-bar&gt;  
   `  
 })  
 export class AppComponent {  
   constructor(private slimLoadingBarService: SlimLoadingBarService) { }  
   startLoading() {  
     this.slimLoadingBarService.start(() =&gt; {  
       console.log('Loading complete');  
     });  
   }  
   stopLoading() {  
     this.slimLoadingBarService.stop();  
   }  
   completeLoading() {  
     this.slimLoadingBarService.complete();  
   }  
 }  
</code></pre>
