## Use example

`ngx-chess-board` exports following components:
* `NgxChessBoardModule`
* `NgxChessBoardService`
* `NgxChessBoardView`

To start, you have to import the `NgxChessBoardModule`:
```typescript
import { NgxChessBoardModule } from "ngx-chess-board";

...
@NgModule({
 ...
 imports: [
 ...
 NgxChessBoardModule
 ...
 ],
 ...
})
export class AppModule { }
```
Next, add following tag in your component's view to render the chess board:
```html
<ngx-chess-board></ngx-chess-board>
```

Then you can inject NgxChessBoardService into your component:

```typescript
import {NgxChessBoardService} from 'ngx-chess-board';

...

constructor(private ngxChessBoardService: NgxChessBoardService) { }
```

You can add reference to `NgxChessBoardView` to interact with specified chess board:
HTML file:
```html
<ngx-chess-board #board></ngx-chess-board>
```
.ts file:
```typescript
import {NgxChessBoardView} from 'ngx-chess-board';

...

@ViewChild('board', {static: false}) board: NgxChessBoardView;

...

reset() {
        this.board.reset();
    }

...
```
