CountUp.js Angular ^2 Module

This is an Angular directive wrapper around the core functionality of CountUp which is maintained in the CountUp.js repo. MIT License.

CountUp.js demo

Or see this angular version work by cloning this project and running ng serve.

Usage

Install the package in your project:

yarn add countup.js-angular2 or npm i countup.js-angular2

In app.module.ts, import the module:

import { CountUpModule } from 'countup.js-angular2';

@NgModule({
  imports: [
    ...
    CountUpModule
  ],
  ...
})

Use it in your markup. Since it's a directive, it can be added to any element:

<h1 [countUp]="345" (complete)="doSomethingOnComplete()">0</h1>

Defer animation

Bind the endVal to some property. Leave it undefined and the animation won't start until endVal has a value.

<h1 [countUp]="myEndVal" [options]="myOpts">0</h1>

Inputs:

• countUp: number to count to
• options: CountUpOptions - fine-grain control over CountUp
• reanimateOnClick: pass false to disable (defaults to true)

Outputs:

• complete: emits when the animation completes
