In this tutorial, we’ll add Ionic Slider in Ionic 5 Angular application and implement sliding effects like Cube, Fade, Flip and Coverflow as animation transitions during the carousel navigation.
The ionic framework provides an Image or content slider which is very popular due to flexible and awesome configuration ability. The ion-sliders UI component is used to implement slider carousel in the application which uses Swiper.js library to create this Slider.
Swiper.js is a popular and widely used carousel library that supports a number of transition effects. The slide effect is used by default other than that it supports Cube, Flip, Fade and Coverflow.
As IonSliders use Swiper.js library, so we are going to implement these effects in an Ionic application. These effects can be easily added to a slider using JS configurations.
Her we will discuss how to create a new Ionic application using the latest version 5 and implement Swiper slider effects.
You can also check our previous tutorial on implementing multiple Swiper sliders on a single page in an Ionic application.
Let’s get started!
#1 Update Ionic CLI
We are going to build an Ionic application in using the latest version of the @ionic/cli package which is 6.6.0. You can update by running below npm command in the terminal
$ npm install -g @ionic/cli
#2 Create a new Ionic 5 application.
After updating the Ionic CLI, execute below ionic command to create a new Ionic application using Angular framework by adding the --type=angular option with a blank template.
$ ionic start ionic-swiper-slider-tutorial blank --type=angularmove to the application folder
$ cd ionic-swiper-slider-tutorial#3 Adding Ionic Slides in Home Page
The ionic framework provides the ion-slides UI component which acts as a wrapper for each slide created by adding ion-slide component. The ion-slides component is basically using the Swiper carousel library, which is very popular and provides a number of configuration options. Ofcourceyou can apply those configurations in Ionic application as well.
In our blank template-based application, open the home.page.html, then add Slides using <ion-slides>Â component
<ion-slides [options]="slideOptsOne" #slideWithNav (ionSlideDidChange)="SlideDidChange(sliderOne,slideWithNav)">
<ion-slide *ngFor="let s of sliderOne.slidesItems">
<img src="../../assets/images/{{s.id}}.jpg">
</ion-slide>
</ion-slides><ion-slides>: Wrapper directive for slider
<ion-slide>: Having each slide, here we have dynamic slides iterating over an object of items.
[options]: Is taking configuration for this slider.
(ionSlideDidChange): Event listener called when a slide is changed.
We’ll add a slider in the Home Page with navigation custom arrows. Now replace below HTML code in the home.page.html file as shown below:
<!-- home.page.html -->
<ion-header [translucent]="true">
<ion-toolbar color="warning">
<ion-title>
Ion-Sliders with Custom Navigation
</ion-title>
</ion-toolbar>
</ion-header>
<ion-content [fullscreen]="true" class="ion-padding">
<h5>Ionic Ion Slider with Navigation Arrows</h5>
<ion-grid>
<ion-row>
<ion-col size="1">
<span class="slider-nav arrow-prev" (click)="slidePrev(sliderOne,slideWithNav)">
<div class="prev-icon-custom custon-nav" [class.disabled]="sliderOne.isBeginningSlide"></div>
</span>
</ion-col>
<ion-col size="10">
<ion-slides pager="false" [options]="slideOptions" #slideWithNav
(ionSlideDidChange)="SlideDidChange(sliderOne,slideWithNav)">
<ion-slide *ngFor="let s of sliderOne.slidesItems">
<img src="https://i.picsum.photos/id/{{s.id}}/400/600.jpg">
</ion-slide>
</ion-slides>
</ion-col>
<ion-col size="1">
<span class="slider-nav arrow-next" (click)="slideNext(sliderOne,slideWithNav)">
<div class="next-icon-custom custon-nav" [class.disabled]="sliderOne.isEndSlide"></div>
</span>
</ion-col>
</ion-row>
</ion-grid>
</ion-content>Here we used Ionic Grid to separate slider and navigation arrows and align them properly in the page.
In the home page component class, we will add @ViewChild decorator to get slider instance and use IonSliders methods to navigate slider using arrows.
Just replace below code in the home.page.ts file for a simple Slider with slide effect which is selected by default.
// home.page.ts
import { Component, ViewChild } from '@angular/core';
import { IonSlides } from '@ionic/angular';
@Component({
selector: 'app-home',
templateUrl: 'home.page.html',
styleUrls: ['home.page.scss'],
})
export class HomePage {
@ViewChild('slideWithNav', { static: false }) slideWithNav: IonSlides;
sliderOne: any;
slideOptions = {
initialSlide: 0,
slidesPerView: 1,
autoplay: true
};
constructor(
) {
//Item object for Nature
this.sliderOne =
{
isBeginningSlide: true,
isEndSlide: false,
slidesItems: [
{
id: 995
},
{
id: 925
},
{
id: 940
},
{
id: 943
},
{
id: 944
}
]
};
}
//Move to Next slide
slideNext(object, slideView) {
slideView.slideNext(500).then(() => {
this.checkIfNavDisabled(object, slideView);
});
}
//Move to previous slide
slidePrev(object, slideView) {
slideView.slidePrev(500).then(() => {
this.checkIfNavDisabled(object, slideView);
});;
}
//Method called when slide is changed by drag or navigation
SlideDidChange(object, slideView) {
this.checkIfNavDisabled(object, slideView);
}
//Call methods to check if slide is first or last to enable disbale navigation
checkIfNavDisabled(object, slideView) {
this.checkisBeginning(object, slideView);
this.checkisEnd(object, slideView);
}
checkisBeginning(object, slideView) {
slideView.isBeginning().then((istrue) => {
object.isBeginningSlide = istrue;
});
}
checkisEnd(object, slideView) {
slideView.isEnd().then((istrue) => {
object.isEndSlide = istrue;
});
}
}
Now if you run your app by hitting $ ionic serve --open , you will see a simple slider with the default slide effect. In the next section, we’ll add new effects.
# Coverflow Slide Effect

Conclusion: In the above tutorial, we discussed how to add Ion-Sliders Swiper Image and Content carousel in the Ionic application and how to add different awesome sliding effects in the slider using JS configuration only. In the SwiperJs library which is used under the hood in ion-sliders component support number of configurations, we can easily modify the slider according to any needs. Just check out Swiper documentation here.
