# ngu-carousel
Angular Universal carousel
`Note: This carousel doesn't include any css. go and customize css for buttons, items except ngucarousel and ngucarousel-inner`
## Demo
Demo available [Here](https://ngu-carousel.netlify.app/)
## Installation
| Angular Version | ngu-carousel Version |
| --------------- | ----------------------------------- |
| Angular >= 15 | `npm i --save @ngu/carousel@latest` |
| Angular >= 14 | `npm i --save @ngu/carousel@6.0.0` |
| Angular >= 13 | `npm i --save @ngu/carousel@5.0.0` |
| Angular >= 12 | `npm i --save @ngu/carousel@4.0.0` |
| Angular >= 10 | `npm i --save @ngu/carousel@3.0.2` |
| Angular = 9 | `npm i --save @ngu/carousel@2.1.0` |
| Angular < 9 | `npm i --save @ngu/carousel@1.5.5` |
## Installation
`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
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: `
<ngu-carousel #myCarousel [inputs]="carouselTile" [dataSource]="carouselTileItems">
<ngu-tile *nguCarouselDef="let item; let i = index">
<ngu-carousel #myCarousel [inputs]="carouselTile" (carouselLoad)="carouselTileLoad(i)" [dataSource]="carouselTiles[i]">
<ngu-tile *nguCarouselDef="let item; let j = index">
<div class="tile" [style.background]="'url(' + item + ')'" style="min-height: 200px">
<h1>{{j}}</h1>
</div>
</ngu-tile>
<button NguCarouselPrev class="leftRs" [style.opacity]="myCarousel.isFirst ? 0.5:1"><</button>
<button NguCarouselNext class="rightRs" [style.opacity]="myCarousel.isLast ? 0.5:1">></button>
<ul class="myPoint" NguCarouselPoint>
<li *ngFor="let j of myCarousel.pointNumbers; let j = index" [class.active]="j==myCarousel.activePoint" (click)="myCarousel.moveTo(j)"
[style.background]="'url(' + carouselTileItems[j] + ')'"></li>
</ul>
</ngu-carousel>
</ngu-tile>
<button NguCarouselPrev class="leftRs" [style.opacity]="myCarousel.isFirst ? 0.5:1"><</button>
<button NguCarouselNext class="rightRs" [style.opacity]="myCarousel.isLast ? 0.5:1">></button>
<ul class="myPoint" NguCarouselPoint>
<li *ngFor="let i of myCarousel.pointNumbers; let i = index" [class.active]="i==myCarousel.activePoint" (click)="myCarousel.moveTo(i)"
[style.background]="'url(' + carouselTileItems[i] + ')'"></li>
</ul>
</ngu-carousel>
`,
})
export class SampleComponent implements OnInit {

'assets/car.png',
'assets/canberra.jpg',

];
public carouselTileItems: Array<any> = [0, 1, 2, 3, 4, 5];
public carouselTiles = {

const len = this.carouselTiles[j].length;
if (len <= 30) {
for (let i = len; i < len + 15; i++) {
this.carouselTiles[j].push(

);
}

| Command | Type | Required | Description |
| ------------------------- | ------------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------- |
| `grid` | Object | Yes | **xs** - mobile, **sm** - tablet, **md** - desktop, **lg** - large desktops, **xl** - extra large desktops, **all** - fixed width (When you use **all** make others 0 and vise versa) |
| `gridBreakpoints` | Object | optional | Determines the browser width in pixels that the grid displays the intended number of tiles.<br/><br/> default: `{sm: 768, md: 992, lg: 1200, xl: 1200}` |
| `slide` | number | optional | It is used to slide the number items on click |

| `interval` | milli seconds | optional | It is used to make carousel auto slide with given value. interval defines the interval between slides |
| `load` | number | optional | is used to load the items similar to pagination. the carousel will tigger the carouslLoad function to load another set of items. it will help you to improve the performance of the app.**`(carouselLoad)="myfunc($event)"`** |
| `point.visible` | boolean | optional | It is used to indicate no. of slides and also shows the current active slide. |
| `point.hideOnSingleSlide` | boolean | optional | It is used to hide the point indicator when slide is less than one. |

### Custom css for Point
```html
<ul class="ngucarouselPoint">
<li *ngFor="let i of pointNumbers; let i = index" [class.active]="i==pointers"></li>
</ul>
```
This is HTML I'm using in the carousel. Add your own css according to this elements in `pointStyles`. check below guide for more details.
```html
<ngu-carousel [inputs]="carouselBanner" (onMove)="onmoveFn($event)" (carouselLoad)="loadItemsFn()">
</ngu-carousel>
```
- `inputs` is an `Input` and It accepts `NguCarouselConfig`.
- `onMove` is an `Output` which triggered on every slide before start and it will emit `$event` as `NguCarouselStore` object.
- `carouselLoad` is an `Output` which triggered when slide reaches the end on items based on inputs `load`.
