Setup

First you need to install the npm module:

npm install ng9-odometer --save

Then add the Ng9OdometerModule to the imports array of your application module.

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { Ng9OdometerModule } from 'ng9-odometer'; // <-- import the module
import { AppComponent} from './app.component';

@NgModule({
    imports: [
      BrowserModule, 
      Ng9OdometerModule.forRoot() // <-- include it in your app module
    ], 
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule {
    //
}

Usage

Use the <ng9-odometer></ng9-odometer> component to create an odometer. The number is required attribute. The number represents the limit at which the odometer will travel. The config an object with the configuration properties, this is NOT required.

@Component({
   selector: 'main-element',
   template: `
        ...
        <ng9-odometer [number]="number" [config]="{ }"></ng9-odometer>
        <!-- Further content here -->
        ...
   `
})
export class MainElementComponent {
  public number: number = 1000;
}

When on manual mode ([config]="{ auto: false }"), you can update the number attribute and that will trigger an odometer update right away. The observable is an Observable which will be used as a trigger for the odometer when on manual mode.

@Component({
   selector: 'main-element',
   template: `
        ...
        <ng9-odometer [number]="number" [config]="{ auto: false }" [observable]="observable"></ng9-odometer>
        <!-- Further content here -->
        ...
   `
})
export class MainElementComponent {
  public number: number = 1000;
  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: `
        ...
        <ng9-odometer 
            [number]="1000" 
            [observable]="observable" 
            [config]="config"></ng9-odometer>
        <!-- Further content here -->

        <ng9-odometer 
            [number]="1000" 
            [observable]="observable"
            [config]="{ animation: 'count', format: 'd', theme: 'car', value: 50, auto: false }">
        </ng9-odometer>
        <!-- Further content here -->

        <ng9-odometer 
            [number]="1000"  
            [observable]="observable"
            [animation]="'count'"
            [format]="'d'"
            [theme]="'car'"
            [value]="0",
            [auto]="false">
        </ng9-odometer>
        <!-- Further content here -->
        ...
   `
})
export class MainElementComponent {
    public config = {
        animation: 'count', 
        format: 'd', 
        theme: 'car', 
        value: 50,
        auto: true,
    }

    ...
}

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