FORK of Vue It Bigger!

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

This version is also using vue-pinch-zoom

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>

• onLastIndex: Emit when the current image is the last one of the list.
• onFirstIndex: Emit when the current image is the first one of the list.
• onStartIndex: Emit when the current image is at the startAt index (specified in the properties).
• onLoad: Emit when there are lengthToLoadMore images left in the array (specified in the properties). For example, if lengthToLoadMore = 2 and there are 7 images in your array, when you reach index 4 (which means there are 2 images left which are not discovered yet), this event will be emitted. After that, if the image array are updated and there are totally 15 images, the event will be emitted at index 12.
