FORK of Vue It Bigger!

npm Build Status codecov Depfu

A simple image / video lightbox component for Vue.js. Forked from vue-it-bigger.

This version is also using vue-pinch-zoom

Vue It Bigger Screenshot

Click on the screenshot above for a demo.

Why I bother to fork it?:

  • Parameter show-light-box is now reactive, whitch is easier to toggle LightBox from parent
  • Parameter start-at is reactive as well
  • Pinch to zoom added, which is useful for mobile view
  • Lazy-load added. Currently with default image only

Features

  • NEW: pinch to zoom
  • NEW: lazy-loader
  • 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

  • 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-vladfork
yarn add vue-it-bigger-vladfork

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-vladfork";
import("vue-it-bigger-vladfork/dist/vue-it-bigger-vladfork.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"
  :show-light-box="showLightBox"
  :start-at="lbStartAt"
  @toggleLightBox="toggleLightBox"
></LightBox>

The media prop has the following structure

[
  {
    // For an 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 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"
      }
    ],
    type: "video",
    caption: "<h4>Monsters Inc.</h4>",
    width: 800, // Required
    height: 600, // Required
    autoplay: true // Optional: Autoplay video when the lightbox opens
  }
];

data variables:

  data () {
    return {
      media: [
        ...
      ]
      showLightBox: false,
      lbStartAt: 0,
      ...
    }
  },

add toggle method to methods:

    toggleLightBox(v) {
      this.showLightBox = v || false
    },

to show the LightBox use a method something like:

  openGallery(index) {
    this.lbStartAt = index || 0
    this.showLightBox = true
  }

Where index is the Index of image you want to pop up

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-vladfork";
import("vue-it-bigger-vladfork/dist/vue-it-bigger-vladfork.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>
