Vue It Bigger!

A simple image / (YouTube) video lightbox component for Vue.js 2. Based on vue-image-lightbox.

Click on the screenshot above for a demo.

Features

• Unobtrusive interface that disappears after a few seconds, reappears on mouse activity
• Optional thumbnail strip with all of the gallery's media
• Can show an HTML enabled caption under each image or video
• Can play the slideshow automatically
• All of the graphics (previous, next and close buttons) can be customized via slots
• Can skip to next / previous media programatically

Improvements over vue-image-lightbox

• Allows embedding YouTube videos
• Lightbox opens and closes with a short fade
• Media's width is no longer limited (stretches to the full width / height of the window)
• When opening the lightbox the media doesn't flicker
• Moved caption bar and image counter off the media to the bottom of the screen
• Moved thumbnails to the top of the screen (as the bottom is now used by the caption bar)
• All interface elements have a background for better visibility
• Simplified CSS

Installation

You know the drill:

npm install vue-it-bigger
# or
yarn add vue-it-bigger

Usage

You can view App.vue or the demo for an usage example.

In the <script> section of your component import it:

import LightBox from 'vue-it-bigger'
import('vue-it-bigger/dist/vue-it-bigger.min.css') // when using webpack

Add it to the list of used components:

export default {
  components: {
    LightBox,
  },
}

And use it in the <template> section:

<LightBox :media="media"></LightBox>

The media prop has the following structure:

[
  { // For an image
    type: 'image', // Can be omitted for image
    thumb: 'http://example.com/thumb.jpg',
    src: 'http://example.com/image.jpg',
    caption: 'Caption to display. HTML <b>enabled</b>', // Optional
    srcset: '...' // Optional for displaying responsive images
  },
  { // For a YouTube video
    type: 'youtube',
    thumb: 'https://img.youtube.com/vi/WsptdUFthWI/hqdefault.jpg',
    id: 'WsptdUFthWI',
    caption: 'HTML <b>enabled</b> caption to display' // Optional
  },
  { // For a video that can be played in the <video> tag
    type: 'video',
    thumb: 'https://s3-us-west-1.amazonaws.com/powr/defaults/image-slider2.jpg',
    sources: [
      {
        src: 'https://www.w3schools.com/html/mov_bbb.mp4',
        type: 'video/mp4'
      }
    ],
    caption: '<h4>Monsters Inc.</h4>',
    width: 800, // Required
    height: 600, // Required
    autoplay: true // Optional: Autoplay video when the lightbox opens
  }
]

Using it with NuxtJs

Create a file named lightbox.js under the plugins directory with following contents:

import Vue from 'vue'

import LightBox from 'vue-it-bigger'
import('vue-it-bigger/dist/vue-it-bigger.min.css')

const plugin = {
  install() {
    Vue.component('LightBox', LightBox)
  },
}

Vue.use(plugin)

Add the plugin in nuxt.config.js:

plugins: [
  {
    src: '~/plugins/lightbox.js',
    ssr: false
  }
]

Use it in any of your components:

<no-ssr placeholder="Loading...">
  <!-- this component will only be rendered on client-side -->
  <LightBox
    :media="lightBoxMedia"
  ></LightBox>
</no-ssr>
