* Run `npm i` to install dependencies
* Create an account & get a Developers API key from [Coinranking](https://developers.coinranking.com/)
* Add API key to `services\authService`
* Enables temporary CORS issue workaround via `https://cors-anywhere.herokuapp.com/corsdemo`
* Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.

## :computer: Code Examples
* extract from `app.component.ts` to create chart2 data
```typescript
this.chart2 = new Chart('canvas2', {
type: 'bar',
data: {
labels: this.coinName,
datasets: [
{
data: this.coinPrice,
borderColor: '#0d47a1',

backgroundColor: 'rgba(93, 175, 89, 0.1)',
borderWidth: 1,
},
],
},
});
```
## :cool: Features
