Usage

<Page xmlns="http://schemas.nativescript.org/tns.xsd"
xmlns:ui="@nstudio/nativescript-shimmer">
...
<ui:Shimmer>
<GridLayout>
<ContentView height="20" width="65%" backgroundColor="#333"/>
</GridLayout>
</ui:Shimmer>

It can also be registered with various flavors, for example with Angular:

import { registerElement } from '@nativescript/angular';
import { Shimmer } from '@nstudio/nativescript-shimmer';

registerElement('Shimmer', () => Shimmer);

// can now be used in components:
<Shimmer>
<GridLayout>
<ContentView height="20" width="65%" backgroundColor="#333"/>
</GridLayout>
</Shimmer>

Properties

  • autoStart: boolean: Default to true. <Shimmer autoStart="false"> to disable starting automatically

iOS Only:

You can start shimmer on any view statically:

import { Shimmer } from '@nstudio/nativescript-shimmer';

loadedView(args) {
view = args.object;
// start shimmer
Shimmer.start(view);
// stop shimmer
Shimmer.stop(view);
}

Android will always need a Shimmer instance to start the effect however you can statically stop the shimmer effect if that instance is passed into Shimmer.stop(view /* shimmer instance */).

  • Shimmer.defaults: you can adjust any of the default effect settings in your app (often in app.ts or main.ts before bootstrap depending on your flavor) to avoid passing in the same settings each time the effect is configured:
Shimmer.defaults = {
speed: 0.9,
direction: ShimmerDirection.topToBottom,
repeat: 4,
lightColor: 'rgba(255,255,255,.8)',
darkColor: 'rgba(0,0,0,.7)',
};

// bootstrap app...
