Different Builds

Since Vue 3.x uses ES2015 (docs faq), there is no need to build ES5 bundle, and ES5 build is removed from version 1.6.0.

Module	Filename
UMD(for browsers)	vue-easy-lightbox.umd.min.js
CommonJS	vue-easy-lightbox.common.min.js (pkg.main)
ES Module(for bundlers)	vue-easy-lightbox.esm.min.js (pkg.module)

External CSS Build

Added in: v1.2.3

By default, CSS is included in dist/*.min.js. In some special cases you may want to import CSS individually to avoid some problems (CSP Violation). You can import builds without CSS and individual .css file from dist/external-css/.

import VueEasyLightbox from 'vue-easy-lightbox/external-css'
// or
import VueEasyLightbox from 'vue-easy-lightbox/dist/external-css/vue-easy-lightbox.esm.min.js'

// you need to import css
import 'vue-easy-lightbox/external-css/vue-easy-lightbox.css'
// or
import 'vue-easy-lightbox/dist/external-css/vue-easy-lightbox.css'

TypeScript Checking error:

If your project is TypeScript project and you get this error message:

Could not find the declaration file for module 'vue-easy-lightbox/dist/external-css/vue-easy-lightbox.esm.min.js'

Here are two ways to solve it.

Way 1: add d.ts in your project:

declare module 'vue-easy-lightbox/dist/external-css/vue-easy-lightbox.esm.min.js' {
  import VueEasyLightbox from 'vue-easy-lightbox'
  export * from 'vue-easy-lightbox'
  export default VueEasyLightbox
}

Way 2: alias

If you're using webpack: webpack alias docs

// wepback.config.js
module.exports = {
  //...
  resolve: {
    alias: {
      'vue-easy-lightbox$': 'vue-easy-lightbox/dist/external-css/vue-easy-lightbox.esm.min.js',
    },
  },
};

// in your component
import VueEasyLightbox from 'vue-easy-lightbox' // work

Or vitejs: vitejs alias

// vite.config.js
import { defineConfig } from 'vite'

export default defineConfig({
  resolve: {
    alias: {
      'vue-easy-lightbox$': 'vue-easy-lightbox/dist/external-css/vue-easy-lightbox.esm.min.js'
    }
  }
})
