Setup

First you need to install the npm module:

npm install ng2-odometer --save

Then add the Ng2OdometerModule to the imports array of your application module.

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { Ng2OdometerModule } from 'ng2-odometer'; // <-- import the module
import { AppComponent} from './app.component';

@NgModule({
    imports: [
      BrowserModule, 
      Ng2OdometerModule.forRoot() // <-- include it in your app module
    ], 
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule {
    //
}

Usage

Use the <ng2-odometer></ng2-odometer> component to create an odometer. The number and observable are required attributes. The number represents the limit at which the odometer will travel. The observable is an Observable which will be used as a trigger for the odometer.

@Component({
   selector: 'main-element',
   template: `
        ...
        <ng2-odometer [number]="1000" [observable]="observable"></ng2-odometer>
        <!-- Further content here -->
        ...
   `
})
export class MainElementComponent {
  public observable: Observable<boolean>;
  private observer: Observer<boolean>;
  
  constructor() {
    this.observable = new Observable<boolean>((observer: any) => this.observer = observer).share();

    // Trigger odometer after 2s
    setTimeout(() => this.observer.next(true), 2000);
  }
}

Configuration

The component accepts either a [config]="{ ... }" attribute with an object with all the configurable attribues or independent attributes for each configuration.

@Component({
   selector: 'main-element',
   template: `
        ...
        <ng2-odometer 
            [number]="1000" 
            [observable]="observable" 
            [config]="config"></ng2-odometer>
        <!-- Further content here -->

        <ng2-odometer 
            [number]="1000" 
            [observable]="observable"
            [config]="{ animation: 'count', format: 'd', theme: 'car', value: 50 }">
        </ng2-odometer>
        <!-- Further content here -->

        <ng2-odometer 
            [number]="1000"  
            [observable]="observable"
            [animation]="'count'"
            [format]="'d'"
            [theme]="'car'"
            [value]="0">
        </ng2-odometer>
        <!-- Further content here -->
        ...
   `
})
export class MainElementComponent {
    public config = {
        animation: 'count', 
        format: 'd', 
        theme: 'car', 
        value: 50
    }

    ...
}

If you add both, the [config] and any independent configuration, the independent config will overwrite the [config] object.

Demo
