load-on-demand

Resource lazy-loading for browser.

This small module allows you to load JavaScript and Stylesheet resources asynchronously inside the browser on demand.

Features

• Loads JavaScript and CSS files on demand, triggers your callback function when everything is loaded
• Loads scripts sequentially according to the specified order
• Loads scripts only when necessary (e.g. loads jQuery only if it's not available already)

Dependencies

Right now this module requires jQuery to work. However, this dependency can be easily removed, feel free to submit a PR on this!

Installation

Install library with Bower

bower install --save betsol-load-on-demand

Install library with NPM

npm i --save betsol-load-on-demand

Add library to your page

<script src="/bower_components/betsol-load-on-demand/dist/betsol-load-on-demand.js"></script>

You should use minified version (betsol-load-on-demand.min.js) in production.

Usage

loadOnDemand({
  stylesheets: [
    '/css/foo.css',
    '/vendor/bar/build/css/bar.css'
  ],
  scripts: {
    angular: [
      '/vendor/angular/angular.min.js'
    ],
    intlTelInput: [
      '/vendor/international-phone-number/international-phone-number.min.js'
    ],
    cfpHotkeys: [
      '/vendor/angular-hotkeys/hotkeys.min.js'
    ]
  }
}, function () {
  // Your code here!
});
