angular2-virtual-scroll

Virtual Scroll displays a virtual, "infinite" list. Supports multi-column.

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.

• Supports multi-column
• Angular 2 compatible module
• Easy to use apis
• OpenSource and available in GitHub

Important Note

Items must have fixed height and width for this module to work perfectly. However if your list happen to have items with variable width and height, set childWidth and childHeight to the smallest possible values manually to make this work.

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

npm install angular2-virtual-scroll --save

Step 2: Import virtual scroll module into your app module

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

....

@NgModule({
    ...
    imports: [
        ....
        VirtualScrollModule
    ],
    ....
})
export class AppModule { }

Step 3: Wrap virtual-scroll tag around list items;

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

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

</virtual-scroll>
