A very easy-to-use asset-loader using promises. Supports images, audio and video. Fully documented for a perfect usage in your TypeScript projects.

Installation

Install using yarn or npm:

• yarn add loaderz
• npm install loaderz --save

// Default export of Loaderz is the Loader.
import Loader from 'loaderz';

// A list of heavy images to load, it could be art-assets for your HTML5 game
const images = [

];

// Some audio elements to spice-up your HTML5 game
const audios = [
  'http://www.sample-videos.com/audio/mp3/crowd-cheering.mp3',
  'http://www.sample-videos.com/audio/mp3/wave.mp3',
];

// Instanciate the loader, you can easily implement it anywhere in your project
const loader = new Loader();

// Queue all our different resources (we can chain since queue returns the
// instance of loader)
loader
  .queue('image', images)
  .queue('audio', audios);

// Start loading the resources and have a full control of the global loading
// state using a promise and return a response with all elements loaded
loader.start()
  .then(response => console.log('All urls have been loaded, do whatever you want here:', response));

Docs

• Loader#queue(type: string, src: string | string[]): accepts 3 different types of medias (audio, image, video).

• Loader#start(): used to load all the queued resources. Returns a global promise of the resources loading.

• Loader#queuedImages: an array of URLs of images queued to load.

• Loader#queuedMedias: an array of MediaData elements queued to load.
