z-image-preloader


Creates a promise object which is resolved when
all images are loaded.

Note: The module depends on the global Promise object to be available.

Since it's a CommonJS module, you must use a build tool to use it, like
Browserify, or webpack.

Example, explanation

``js
const preloader = require("z-image-preloader");

// load single image
preloader
.load("http://some-url/some-image.png")
.then(img => {
// done loading
})
.catch(e => {
// failed to load
});

// The batchLoad method accepts an array of url strings. (Or a single url.)
// The returned promise will be resolved, when all images are loaded (or failed to load)
preloader
.batchLoad([
"http://some-url/some-image.png",
"http://some-other-url/some-other-image.jpg",
"non-existent-image"
])
.then((img1, img2, err) => {
// Do something when preloading is done.
// The arguments here will contain the loaded image objects created by document.createElement('img') and possible Error objects.
// The above call for example will return with two HTMLImageElement and an Error.
});
