Lightweight drag to scroll carousel for Angular
Scroll on drag!
Try out the demo!
You can get it on npm.
npm install ngx-drag-scroll --saveThis project needs Angular 5+ as dependencies though.
You'll need to add DragScrollModule to your application module.
import { DragScrollModule } from 'ngx-drag-scroll';
...
@NgModule({
declarations: [
AppComponent
],
imports: [
DragScrollModule,
...
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule {
}Add the drag-scroll attribute to a scrollable element:
@Component({
selector: 'sample',
template:`
<drag-scroll style="width: 100px; height: 10px">
Big text goes here...
</drag-scroll>
`,
styles: [`
drag-scroll {
height: 50px
width: 100px
}
`]
})
class SampleBigText {}That's it! Now you can scroll it by dragging.
If you want to group items into a carousel, you will need to add drag-scroll-item to the carsousel items.
@Component({
selector: 'sample',
template:`
<drag-scroll>
<img drag-scroll-item src="some-url" />
<img drag-scroll-item src="some-url" />
<img drag-scroll-item src="some-url" />
</drag-scroll>
`,
styles: [`
drag-scroll {
height: 50px
width: 100px
}
img {
height: 50px
width: 50px
}
`]
})

@Component({
selector: 'sample',
template:`
<drag-scroll #nav>
<img drag-scroll-item src="some-url" />
<img drag-scroll-item src="some-url" />
<img drag-scroll-item src="some-url" />
</drag-scroll>
<button (click)="moveLeft()">Left</button>
<button (click)="moveRight()">Right</button>
<button (click)="moveTo(2)">Last</button>
`
})
class Sample {
@ViewChild('nav', {read: DragScrollComponent}) ds: DragScrollComponent;
moveLeft() {
this.ds.moveLeft();
}
moveRight() {
this.ds.moveRight();
}
moveTo(index) {
this.ds.moveTo(index);
}
ngAfterViewInit() {
// Starting ngx-drag-scroll from specified index(3)
setTimeout(() => {
this.ds.moveTo(3);
}, 0);
}
}Clone the repository, and run npm install, npm run build ngx-drag-scroll, npm start. The demo app will starts on port :4200. I usually do my development on the demo app.
