Try out the demo!

Install

You can get it on npm.

npm install ngx-drag-scroll --save

Requirements

This project needs Angular 5+ as dependencies though.

Setup

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
    }
    `]
})
class SampleCarousel {}
