Getting started

See demo for further details.

1. Download and install the module via npm to your Nativescript project:

cd your_tns_project_path/
npm install nativescript-ng2-carousel --save

2. Add the CarouselDirective class to the declarations NgMoudle metadata:

@NgModule({
    declarations: [AppComponent, CarouselDirective],
    bootstrap: [AppComponent],
    imports: [NativeScriptModule],
    schemas: [NO_ERRORS_SCHEMA]
})

3. To use the CarouselDirective, create a template that applies the directive as an attribute to a paragraph GridLayout element:

<GridLayout [carousel]="images" carouselLabelOverlay="true" carouselSpeed="2000">
    
</GridLayout>

Add images from URL to your component:

@Component({
    selector: "my-app",
    templateUrl: "app.component.html"
})
export class AppComponent {

    protected images: Array = [];

    constructor() {
        this.images = [
            { title: 'Image 1', url: 'https://unsplash.it/400/300/?image=867' },
            { title: 'Image 2', url: 'https://unsplash.it/400/300/?image=870' },
            { title: 'Image 3', url: 'https://unsplash.it/400/300/?image=876' },
        ];
    }
}

You can also add images from your assets folder or resources folder using file attribute instead of url attribute:

@Component({
    selector: "my-app",
    templateUrl: "app.component.html"
})
export class AppComponent {

    protected images: Array = [];

    constructor() {
        this.images = [
            { title: 'Image 1', url: 'https://unsplash.it/400/300/?image=867' },
            { title: 'Image 2', file: '~/assets/sea-sunset.jpg' },
            { title: 'Image 2', file: 'res://mountain' }, // Resource without extension
            { title: 'Image 3', url: 'https://unsplash.it/400/300/?image=876' },
        ];
    }
}

4. CSS styling:

/** Slider image */
.slider-image {

}

/** Slider title format */
.slider-title {
    color: #fff;
    font-weight: bold;
    background-color: rgba(125, 125, 125);
    padding: 8;
    text-align: center;
    vertical-align: bottom;
}

.arrow {
    color: #ffffff;
    font-size: 32;
