Angular Universal carousel
npm install ngu-carouselAngular Universal carousel
Note: This carousel doesn't include any css. go and customize css for buttons, items except ngucarousel and ngucarousel-inner
for ChangeLog go to CHANGELOG.md
Demo available in Stackblitz Here
Demo available Here
npm install @ngu/carousel --save
Include CarouselModule in your app module:
``javascript
import { NguCarouselModule } from '@ngu/carousel';
@NgModule({
imports: [NguCarouselModule]
})
export class AppModule {}
`
Now ngu-carousel supports touch with the help of hammerjs
npm install hammerjs --save
Import hammerjs in main.ts file
`javascript`
import 'hammerjs';
Then use in your component:
`javascript
import { Component, OnInit } from '@angular/core';
import { NguCarouselConfig } from '@ngu/carousel';
@Component({
selector: 'sample',
template:
{{j}}
[style.background]="'url(' + carouselTileItems[j] + ')'">
,
})
export class SampleComponent implements OnInit {
imgags = [
'assets/bg.jpg',
'assets/car.png',
'assets/canberra.jpg',
'assets/holi.jpg'
];
public carouselTileItems: Array
public carouselTiles = {
0: [],
1: [],
2: [],

5: []
};
public carouselTile: NguCarouselConfig = {

};
constructor() {}
ngOnInit() {
this.carouselTileItems.forEach(el => {
this.carouselTileLoad(el);
});
}
public carouselTileLoad(j) {
// console.log(this.carouselTiles[j]);
const len = this.carouselTiles[j].length;
if (len <= 30) {
for (let i = len; i < len + 15; i++) {
this.carouselTiles[j].push(
this.imgags[Math.floor(Math.random() * this.imgags.length)]
);
}
}
}
