Migrating From ion-slides to Swiper.js

ion-slides を探していますか？

ion-slides は v6.0.0 で非推奨となり、v7.0.0 で削除されました。直接 Swiper.js ライブラリを使用することをお勧めします。移行手順は以下の通りです。

We recommend Swiper.js if you need a modern touch slider component. This guide will go over how to get Swiper for Vue set up in your Ionic Framework application. It will also go over any migration information you may need to move from ion-slides to the official Swiper Vue integration.

note

Swiper's Vue component is set to be removed in a future release of Swiper, with Swiper Element as the replacement. However, this guide shows how to migrate to the Vue component because it provides the most stable experience at the time of writing.

Using Swiper's Vue component is not required to use Swiper.js with Ionic Framework.

Getting Started

First, update to the latest version of Ionic:

npm install @ionic/vue@latest @ionic/vue-router@latest

We recommend upgrading to Vue CLI 5 for better compatibility with Swiper:

vue upgrade --next

Once that is done, install the Swiper dependency in your project:

npm install swiper@latest

Swiping with Style

Next, we need to import the base Swiper styles. We are also going to import the styles that Ionic provides which will let us customize the Swiper styles using the same CSS Variables that we used with ion-slides.

We recommend importing the styles in the component in which Swiper is being used. This ensures that the styles are only loaded when needed:

<script setup lang="ts">
import 'swiper/css';
import '@ionic/vue/css/ionic-swiper.css';
</script>

note

Importing @ionic/vue/css/ionic-swiper.css is not required to use Swiper.js with Ionic. This files is used for backward-compatibility with the ion-slides component and can be safely omitted if you prefer not to use the CSS Variables provided in the stylesheet.

Updating Selectors

Previously, we were able to target ion-slides and ion-slide to apply any custom styling. The contents of those style blocks remain the same, but we need to update the selectors. Below is a list of selector changes when going from ion-slides to Swiper Vue:

ion-slides Selector	Swiper Selector
`ion-slides`	`.swiper`
`ion-slide`	`.swiper-slide`

Pre-processors (optional)

For developers using SCSS or Less styles, Swiper also provides imports for those files.

For Less styles, replace css with less in the Swiper import path:

import 'swiper/less';
import '@ionic/vue/css/ionic-swiper.css';

For SCSS styles replace css with scss in the Swiper import path:

import 'swiper/scss';
import '@ionic/vue/css/ionic-swiper.css';

Using Components

Swiper exports two components: Swiper and SwiperSlide. The Swiper component is the equivalent of IonSlides, and SwiperSlide is the equivalent of IonSlide.

These components are imported from swiper/vue and provided to your Vue component:

<template>
  <ion-page>
    <ion-content>
      <swiper>
        <swiper-slide>Slide 1</swiper-slide>
        <swiper-slide>Slide 2</swiper-slide>
        <swiper-slide>Slide 3</swiper-slide>
      </swiper>
    </ion-content>
  </ion-page>
</template>

<script setup lang="ts">
import { Swiper, SwiperSlide } from 'swiper/vue';
import { IonContent, IonPage } from '@ionic/vue';

import 'swiper/css';
import '@ionic/vue/css/ionic-swiper.css';
</script>

Using Modules

By default, Swiper for Vue does not import any additional modules. To use modules such as Navigation or Pagination, you need to import them first.

ion-slides automatically included the Pagination, Scrollbar, Autoplay, Keyboard, and Zoom modules. This part of the guide will show you how to install these modules.

To begin, we need to import the modules and their corresponding CSS files from the swiper package:

<template>
  <ion-page>
    <ion-content>
      <swiper>
        <swiper-slide>Slide 1</swiper-slide>
        <swiper-slide>Slide 2</swiper-slide>
        <swiper-slide>Slide 3</swiper-slide>
      </swiper>
    </ion-content>
  </ion-page>
</template>
<script setup lang="ts">
import { Autoplay, Keyboard, Pagination, Scrollbar, Zoom } from 'swiper/modules';
import { Swiper, SwiperSlide } from 'swiper/vue';
import { IonContent, IonPage } from '@ionic/vue';

import 'swiper/css';
import 'swiper/css/autoplay';
import 'swiper/css/keyboard';
import 'swiper/css/pagination';
import 'swiper/css/scrollbar';
import 'swiper/css/zoom';
import '@ionic/vue/css/ionic-swiper.css';
</script>

From here, we need to provide these modules to Swiper by using the modules property on the swiper component:

<template>
  <ion-page>
    <ion-content>
      <swiper :modules="modules">
        <swiper-slide>Slide 1</swiper-slide>
        <swiper-slide>Slide 2</swiper-slide>
        <swiper-slide>Slide 3</swiper-slide>
      </swiper>
    </ion-content>
  </ion-page>
</template>
<script>
import { Autoplay, Keyboard, Pagination, Scrollbar, Zoom } from 'swiper/modules';
import { Swiper, SwiperSlide } from 'swiper/vue';
import { IonContent, IonPage } from '@ionic/vue';

import 'swiper/css';
import 'swiper/css/autoplay';
import 'swiper/css/keyboard';
import 'swiper/css/pagination';
import 'swiper/css/scrollbar';
import 'swiper/css/zoom';
import '@ionic/vue/css/ionic-swiper.css';

const modules = [Autoplay, Keyboard, Pagination, Scrollbar, Zoom];
</script>

Finally, we can turn these features on by using the appropriate properties:

<template>
  <ion-page>
    <ion-content>
      <swiper :modules="modules" :autoplay="true" :keyboard="true" :pagination="true" :scrollbar="true" :zoom="true">
        <swiper-slide>Slide 1</swiper-slide>
        <swiper-slide>Slide 2</swiper-slide>
        <swiper-slide>Slide 3</swiper-slide>
      </swiper>
    </ion-content>
  </ion-page>
</template>
<script>
import { Autoplay, Keyboard, Pagination, Scrollbar, Zoom } from 'swiper/modules';
import { Swiper, SwiperSlide } from 'swiper/vue';
import { IonContent, IonPage } from '@ionic/vue';

import 'swiper/css';
import 'swiper/css/autoplay';
import 'swiper/css/keyboard';
import 'swiper/css/pagination';
import 'swiper/css/scrollbar';
import 'swiper/css/zoom';
import '@ionic/vue/css/ionic-swiper.css';

const modules = [Autoplay, Keyboard, Pagination, Scrollbar, Zoom];
</script>

The IonicSlides Module

With ion-slides, Ionic automatically customized dozens of Swiper properties. This resulted in an experience that felt smooth when swiping on mobile devices. We recommend using the IonicSlides module to ensure that these properties are also set when using Swiper directly. However, using this module is not required to use Swiper.js in Ionic.

It is recommended to review the properties set by IonicSlides and determine which ones you would like to customize.

We can install the IonicSlides module by importing it from @ionic/vue and passing it in as the last item in the modules array:

<template>
  <ion-page>
    <ion-content>
      <swiper :modules="modules" :autoplay="true" :keyboard="true" :pagination="true" :scrollbar="true" :zoom="true">
        <swiper-slide>Slide 1</swiper-slide>
        <swiper-slide>Slide 2</swiper-slide>
        <swiper-slide>Slide 3</swiper-slide>
      </swiper>
    </ion-content>
  </ion-page>
</template>
<script setup lang="ts">
import { Autoplay, Keyboard, Pagination, Scrollbar, Zoom } from 'swiper/modules';
import { Swiper, SwiperSlide } from 'swiper/vue';
import { IonContent, IonPage, IonicSlides } from '@ionic/vue';

import 'swiper/css';
import 'swiper/css/autoplay';
import 'swiper/css/keyboard';
import 'swiper/css/pagination';
import 'swiper/css/scrollbar';
import 'swiper/css/zoom';
import '@ionic/vue/css/ionic-swiper.css';

const modules = [Autoplay, Keyboard, Pagination, Scrollbar, Zoom, IonicSlides];
</script>

note

The IonicSlides module must be the last module in the array. This will let it automatically customize the settings of modules such as Pagination, Scrollbar, Zoom, and more.

Properties

Swiper options are provided as props directly on the <swiper> component rather than via the options object in ion-slides.

Let's say in an app with ion-slides we had the slidesPerView and loop options set:

<template>
  <ion-slides :options="{ slidesPerView: 3, loop: true }">
    <ion-slide>Slide 1</ion-slide>
    <ion-slide>Slide 2</ion-slide>
    <ion-slide>Slide 3</ion-slide>
  </ion-slides>
</template>

To migrate, we would move these options out of the options object and onto the <swiper> component directly as properties:

<template>
  <swiper :slides-per-view="3" :loop="true">
    <swiper-slide>Slide 1</swiper-slide>
    <swiper-slide>Slide 2</swiper-slide>
    <swiper-slide>Slide 3</swiper-slide>
  </swiper>
</template>

Below is a full list of property changes when going from ion-slides to Swiper Vue:

Name	Notes
options	Set each option as a property directly on the `<swiper>` component.
mode	For different styles based upon the mode, you can target the slides with `.ios .swiper` or `.md .swiper` in your CSS.
pager	Use the `pagination` property instead. Requires installation of the Pagination module.
scrollbar	You can continue to use the `scrollbar` property, just be sure to install the Scrollbar module first.

note

Events

Since the Swiper component is not provided by Ionic Framework, event names will not have an ionSlide prefix to them.

Let's say in an app with ion-slides we used the ionSlideDidChange event:

<template>
  <ion-slides @ionSlideDidChange="onSlideChange">
    <ion-slide>Slide 1</ion-slide>
    <ion-slide>Slide 2</ion-slide>
    <ion-slide>Slide 3</ion-slide>
  </ion-slides>
</template>

To migrate, we would change the name of the event to slideChange:

<template>
  <swiper @slideChange="onSlideChange">
    <swiper-slide>Slide 1</swiper-slide>
    <swiper-slide>Slide 2</swiper-slide>
    <swiper-slide>Slide 3</swiper-slide>
  </swiper>
</template>

Below is a full list of event name changes when going from ion-slides to Swiper Vue:

ion-slides Event	Swiper Event
`ionSlideWillChange`	`slideChangeTransitionStart`
`ionSlideDidChange`	`slideChangeTransitionEnd`
`ionSlideDoubleTap`	`doubleTap`
`ionSlideDrag`	`sliderMove`
`ionSlideNextStart`	`slideNextTransitionStart`
`ionSlideNextEnd`	`slideNextTransitionEnd`
`ionSlidePrevStart`	`slidePrevTransitionStart`
`ionSlidePrevEnd`	`slidePrevTransitionEnd`
`ionSlideReachStart`	`reachBeginning`
`ionSlideReachEnd`	`reachEnd`
`ionSlideTap`	`tap`
`ionSlideTouchStart`	`touchStart`
`ionSlideTouchEnd`	`touchEnd`
`ionSlideTransitionStart`	`transitionStart`
`ionSlideTransitionEnd`	`transitionEnd`
`ionSlidesDidLoad`	`init`

Methods

Most methods have been removed in favor of accessing the <swiper> props directly. Additionally, you no longer need to access $el first when calling methods.

Accessing these properties can be tricky as you want to access the properties on the Swiper instance itself, not your Vue component. To do this, we recommend getting a reference to the Swiper instance via the @swiper event handler:

<template>
  <swiper @swiper="setSwiperInstance"> ... </swiper>
</template>

<script setup lang="ts">
import { ref } from 'vue';

const slides = ref();
const setSwiperInstance = (swiper: any) => {
  slides.value = swiper;
};
</script>

From here, if you wanted to access a property on the Swiper instance you would access slides.value. For example, if you wanted to check the isBeginning property, you could do: slides.value.isBeginning. Make sure slides.value is defined first though!

Below is a full list of method changes when going from ion-slides to Swiper Vue:

ion-slides Method	Notes
`getActiveIndex()`	Use the `activeIndex` property instead.
`getPreviousIndex()`	Use the `previousIndex` property instead.
`getSwiper()`	Get a reference to the Swiper instance using `@swiper`. See example above.
`isBeginning()`	Use the `isBeginning` property instead.
`isEnd()`	Use the `isEnd` property instead.
`length()`	Use the `slides` property instead. (i.e swiperRef.slides.length)
`lockSwipeToNext()`	Use the `allowSlideNext` property instead.
`lockSwipeToPrev()`	Use the `allowSlidePrev` property instead.
`lockSwipes()`	Use the `allowSlideNext`, `allowSlidePrev`, and `allowTouchMove` properties instead.
`startAutoplay()`	Use the `autoplay` property instead.
`stopAutoplay()`	Use the `autoplay` property instead.

Effects

If you are using effects such as Cube or Fade, you can install them just like we did with the other modules. In this example, we will use the fade effect. To start, we will import EffectFade from swiper and provide it in the modules array:

<template>
  <ion-page>
    <ion-content>
      <swiper :modules="modules">
        <swiper-slide>Slide 1</swiper-slide>
        <swiper-slide>Slide 2</swiper-slide>
        <swiper-slide>Slide 3</swiper-slide>
      </swiper>
    </ion-content>
  </ion-page>
</template>
<script>
import { EffectFade } from 'swiper/modules';
import { Swiper, SwiperSlide } from 'swiper/vue';
import { IonContent, IonPage, IonicSlides } from '@ionic/vue';

import 'swiper/css';
import '@ionic/vue/css/ionic-swiper.css';

const modules = [EffectFade, IonicSlides];
</script>

Next, we need to import the stylesheet associated with the effect:

<template>
  <ion-page>
    <ion-content>
      <swiper :modules="modules">
        <swiper-slide>Slide 1</swiper-slide>
        <swiper-slide>Slide 2</swiper-slide>
        <swiper-slide>Slide 3</swiper-slide>
      </swiper>
    </ion-content>
  </ion-page>
</template>
<script>
import { EffectFade } from 'swiper/modules';
import { Swiper, SwiperSlide } from 'swiper/vue';
import { IonContent, IonPage, IonicSlides } from '@ionic/vue';

import 'swiper/css';
import 'swiper/css/effect-fade';
import '@ionic/vue/css/ionic-swiper.css';

const modules = [EffectFade, IonicSlides];
</script>

After that, we can activate it by setting the effect property on swiper to "fade":

<template>
  <ion-page>
    <ion-content>
      <swiper :modules="modules" effect="fade">
        <swiper-slide>Slide 1</swiper-slide>
        <swiper-slide>Slide 2</swiper-slide>
        <swiper-slide>Slide 3</swiper-slide>
      </swiper>
    </ion-content>
  </ion-page>
</template>
<script>
import { EffectFade } from 'swiper/modules';
import { Swiper, SwiperSlide } from 'swiper/vue';
import { IonContent, IonPage, IonicSlides } from '@ionic/vue';

import 'swiper/css';
import 'swiper/css/effect-fade';
import '@ionic/vue/css/ionic-swiper.css';

const modules = [EffectFade, IonicSlides];
</script>
