vitepress-plugin-lightbox

Plugin for VitePress to add support for viewing images in lightboxes, you can check out the example site here. It is also available on NPM.

This plugin is built using the medium-zoom package.

Installation

First, install the plugin from NPM.

npm install -D vitepress-plugin-lightbox

Then import it and update your VitePress config.mts file to use the plugin as shown below.

import { defineConfig } from "vitepress";

// Import lightbox plugin
import lightbox from "vitepress-plugin-lightbox"

// https://vitepress.dev/reference/site-config
export default defineConfig({
  title: "docs",
  description: "my docs",
  cleanUrls: true,
  themeConfig: {
    ...
  },
  markdown: {
    config: (md) => {
      // Use lightbox plugin
      md.use(lightbox, {});
    },
  },
});

Now create the .vitepress/theme directory, and add the following two files.

.vitepress/theme/index.ts

import DefaultTheme from "vitepress/theme";
import Layout from "./Layout.vue";

export default {
  extends: DefaultTheme,
  Layout,
};

.vitepress/theme/Layout.vue

<script setup>
import DefaultTheme from "vitepress/theme";
import { onMounted } from "vue";
import { useRouter } from "vitepress";
import mediumZoom from "medium-zoom";

const { Layout } = DefaultTheme;
const router = useRouter();

// Setup medium zoom with the desired options
const setupMediumZoom = () => {
  mediumZoom("[data-zoomable]", {
    background: "transparent",
  });
};

// Apply medium zoom on load
onMounted(setupMediumZoom);

// Subscribe to route changes to re-apply medium zoom effect
router.onAfterRouteChanged = setupMediumZoom;
</script>

<template>
  <Layout />
</template>

<style>
.medium-zoom-overlay {
  backdrop-filter: blur(5rem);
}

.medium-zoom-overlay,
.medium-zoom-image--opened {
  z-index: 999;
