Table of Contents

## Installation

Install it with npm

npm install ng2-progressbar --save

SystemJS

If you are using SystemJS, you should also adjust your configuration to point to the UMD bundle.

In your systemjs config file, map needs to tell the System loader where to look for ng2-progressbar:

map: {
  'ng2-progressbar': 'node_modules/ng2-progressbar/bundles/ng2-progressbar.umd.js',
}

Here is a working plunker.

## Usage

Add NgProgressModule to NgModule imports array.

import { NgProgressModule } from 'ng2-progressbar';
 
@NgModule({
imports: [
    NgProgressModule
  ]
})

In your template

<ng-progress></ng-progress>

Add NgProgressService wherever you want to use the progressbar.

import {NgProgressService} from "ng2-progressbar";
 
@Component({
 /**  */ 
})
constructor(private pService: NgProgressService) {
  }
  
  ngOnInit(){
      /** request started */
      this.pService.start();
      this.http.get(url).subscribe(res){
          /** request completed */
          this.pService.done();
      }
  }

NgProgressService options (functions):

  • NgProgressService.start() Shows the progress bar

  • NgProgressService.set(n) Sets a percentage n (where n is between 0-1)

  • NgProgressService.inc(n) Increments by n (where n is between 0-1)

  • NgProgressService.done() Completes the progress

NgProgressComponent options (inputs):

<ng-progress [positionUsing]="'marginLeft'" [minimum]="0.15" [maximum]="1"
             [speed]="'200'" [showSpinner]="'false'" [direction]="'rightToLeftIncreased'"
             [color]="'red'" [trickleSpeed]="250" [thick]="false" [ease]="'linear'"
></ng-progress>

Automagic loading bar (BETA)

If you only need a progressbar for multiple (XHR) requests, there is a simple plug and play provider. It does the trick.

import { NgProgressCustomBrowserXhr } from 'ng2-progressbar';
 
@NgModule({
  
  providers: [
    { provide: BrowserXhr, useClass: NgProgressCustomBrowserXhr } ,
  ],
})
<ng-progress></ng-progress>

The progress will start and complete automatically with your HTTP requests. no need to use NgProgressService to call start()/done() manually.

## Issues

If you identify any errors in the library, or have an idea for an improvement, please open an issue. I am excited to see what the community thinks of this project, and I would love your input!
