angular2-virtual-scroll

Virtual Scroll displays a virtual, "infinite" list.

About

This module does not render every record in the list at once; instead a small subset of records just enough to fill the viewport are rendered and reused as the user scrolls. Thus displaying an infinitely growing list of items in a viewport of size just about a couple rows in an efficient way is made possible.

• Angular 2 compatible module
• Easy to use apis
• OpenSource and available in GitHub

Note: Items must have a fixed height and width for this module to work perfectly.

Usage

<virtual-scroll [items]="items" (update)="viewPortItems = $event">

    <list-item *ngFor="let item of viewPortItems" [item]="item">
    </list-item>

</virtual-scroll>

Get Started

Step 1: Install angular2-virtual-scroll

Step 2: Import virtual scroll module into your app module

....
import { VirtualScrollModule } from 'angular2-virtual-scroll';

@NgModule({
    ...
    imports: [
        ....
