Install it with npm

npm install ngx-progressbar --save


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 ngx-progressbar:

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

Here is a working plunker.


Import NgProgressModule in the root module

import { NgProgressModule } from 'ngx-progressbar';

  imports: [
    // ...

In your template


Add NgProgressService wherever you want to use the progressbar.

import {NgProgressService} from 'ngx-progressbar';

 /**  */ 
export class SomeComponent {
  constructor(public pService: NgProgressService) {
      /** request started */
          /** request completed */

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'"
  • [minimum]: between 0.0 to 1.0.

Progress initial starting value, default 0.08

  • [maximum]: between 0.0 to 1.0.

Progress initial starting value, default 0.08

Progress animation ease, default linear.

  • [speed]: in milliseconds.

Transition speed, default 300.

  • [trickleSpeed]: in milliseconds.

Progress trickling speed, default 300.

  • [direction]: leftToRightIncreased, leftToRightReduced , rightToLeftIncreased, rightToLeftReduced.

Progressbar direction for LTR and RTL websites, default: leftToRightIncreased.

  • [positionUsing]: marginLeft, translate, translate3d.

Positioning method, default: marginLeft

  • [color]: any color format #1eb77f, brown, rgb(30, 183, 127).

Set the progressbar color, default: #29d

  • [showSpinner]: boolean

Display the spinner, default: true.

  • [thick]: boolean

A thicker size of the progressbar, default: false.

  • [toggle]: boolean

Toggle the progressbar (alternate to start/done), . default false.

Automagic loading bar

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 'ngx-progressbar';

 providers: [
   // ...
   { provide: BrowserXhr, useClass: NgProgressCustomBrowserXhr } ,
 imports: [
   // ...

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


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!
