v-agile

This is a customized version of vue-agile with smaller bundle size and better performance.

Demo & examples

Installation

npm install v-agile

or

yarn add v-agile

Styles

The component is delivered without styles for the appearance of the navigation elements (like dots color and shape, arrows position, etc.). I think most people use their own styles and default styles are completely redundant. If you want, feel free to use styles from CodePen demos.

Importing

Global

// main.js
import { createApp } from 'vue'
import App from './App.vue'
import VAgile from 'v-agile'

createApp(App)
  .use(VAgile)

In component

// YourComponent.vue
import { Agile } from 'v-agile'

export default {
  components: {
    agile: Agile
  }
}

Via <script>

<script src="https://unpkg.com/v-agile"></script>
<link rel="stylesheet" href="https://unpkg.com/v-agile/lib/v-agile.css">

Usage

<template>
  <agile>
    <div class="slide">
      <h3>slide 1</h3>
    </div>

    ...

    <div class="slide">
      <h3>slide n</h3>
    </div>
  </agile>
</template>

Every first-level child of <agile> is a new slide. You also can group them inside <template v-slot:default>...</template> tags.

Methods

| Name | Description | | --- | --- | | getCurrentBreakpoint() | Returns current breakpoint (can returns 0 in mobile first for the smallest breakpoint and null for desktop first for the largest) | | getCurrentSettings() | Returns settings object for current breakpoint – useful for debugging | | getCurrentSlide() | Returns index of current slide | | getInitialSettings() | Returns full settings object with all options – useful for debugging | | goTo() | Navigates to a slide by index | | goToNext() | Navigates to next slide | | goToPrev() | Navigate to previous slide | | reload() | Reload carousel & slides settings, classes and inline styles |

Example

<agile ref="carousel">...</agile>

<button @click="$refs.carousel.goToNext()">My custom button</button>

Events

| Name | Value | Description | | --- | --- | --- | | after-change | { currentSlide } | Fires after slide change | | before-change | { currentSlide, nextSlide } | Fires before slide change | | breakpoint | { breakpoint } | Fires after breakpoint change |

Example

<agile @after-change="showCurrentSlide($event)">...</agile>

showCurrentSlide(event)
{
  console.log(event)
  // Shows for example: { currentSlide: 1 }
}

Responsive

To customize responsiveness, I recommend defining your desired breakpoints and passing settings object with your modification options inside options.

Example

<agile :options="myOptions">...</agile>

data()
{
  return {
    myOptions: {
      navButtons: false,
      responsive: [
        {
          breakpoint: 600,
          settings: {
            dots: false
          }
        },

        {
          breakpoint: 900,
          settings: {
            navButtons: true,
            dots: true,
            infinite: false
          }
        }
      ]
    }
  }
}

How does it work? Mobile first mode is used by default. It means, that navButtons: false option will be used on screens from 0 to 600 px width (+ all default carousel options). On screens from 600 to 900 px dots: false will be added to options from breakpoint before. And on screens over 900 px width navButtons and dots options will be overwritten and infinite: false will be added.

Custom arrows / nav buttons

From version 1.0 the component use slots for custom navigation buttons. It means you can put inside whatever you want – any HTML with text, image, icon etc.

Example

<agile>
... <!-- slides -->

<template slot="prevButton">prev</template>
<template slot="nextButton">next</template>
</agile>

Caption

To display a static caption or such like within the gallery, you can use the caption slot.

Example

<agile @after-change="e => currentSlide = e.currentSlide">
  ... <!-- slides -->

  <template slot="caption">{{ captions[currentSlide] }}</template>
</agile>

<script>
  export default {
    data () {
      return {
        currentSlide: 0,
        captions: [
          'This is slide 1',
          'This is the second slide',
          'This is a third and final slide',
        ]
      }
    }
  }
</script>

asNavFor

This option is useful for example for creating a photo gallery with two related slider – one big with only one slide in view and second for navigation with thumbnails.

Example

<agile ref="main" :fade="true">...</agile>

<agile ref="thumbnails" :as-nav-for="[$refs.main]" :slides-to-show="4" autoplay>...</agile>

Important! If you want to use the autoplay mode use it only in one of the related carousels.

v-if & v-show

If you have slides being dynamically loaded, use v-if to show the carousel after the slides are ready. Using v-if is also recommended in other situations if you want to hide/show the slideshow.

It is also possible to use v-show, but you have to use the reload() method.

Example

<button @click="isActive = !isActive">Toggle carousel</button>

<agile v-if="isActive">...</agile>

Nuxt.js && SSR Support

The component uses browser specific attributes (like window and document). However, you can try to render the first view on server side.

Example

// plugins/v-agile.js

import Vue from 'vue'
import VAgile from 'v-agile'

Vue.use(VAgile)

// nuxt.config.js

export default {
  plugins: ['~/plugins/v-agile'],

  build: {
    transpile: ['v-agile']
  }
}

To use component without SSR use the client-only component:

<client-only placeholder="Loading...">
  <agile>...</agile>
</client-only>

Important! Component rendered on server side has additional CSS class: agile--ssr, so you can use it to add some additional styles or manipulations. For example, I have limited options for setting the first appearance of the slides. By default, the server renders the view and styles, where only the first slide is visible.

.agile--ssr .agile__slides > * {
  overflow: hidden;
  width: 0
}

.agile--ssr .agile__slides > *:first-child {
  width: 100%
}

At this stage slides don't have agile__slide class yet, so I use > * instead of this.

If you would like to connect this with params slidesToShow or initialSlide you have to add some custom styles with nth-child param.

Example for :slidesToShow="2"

.agile--ssr
  .agile__slides
    > *:nth-child(1),
    > *:nth-child(2)
      width: 50%

Example for :initialSlide="1"

(Slides index starts at 0)

.agile--ssr
  .agile__slides
    > *:nth-child(1)
      width: 0

    > *:nth-child(2)
      width: 100%
