gulp-img2js

A Gulp plugin for embedding images to javascript sources

What does it do

will be converted to a js file:

function createImages() {
    "use strict";
    var result = {};
    result.addUser = new Image();
    result.addUser.src = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAT...==';
    result.agenda = new Image();
    result.agenda.src = 'data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAdAB0M...==';
    result.eyeFoo = new Image();
    result.eyeFoo.src = 'data:image/gif;base64,R0lGODlhQ77+MdADrKQh0xkksgQ...=';
    result.folder1 = new Image();
    result.folder1.src = 'data:image/png;base64,iVsm+MCPj7SXEAAAAASUVORK5C...=';
    return result;
}

and can be used for example as:

window.onload = function() {
	let canvas = document.getElementById('viewport');
	let ctx = canvas.getContext('2d');
	let images  = createImages();

	ctx.drawImage(images.addUser, 0, 0);
	ctx.drawImage(images.agenda, 100, 0);
	ctx.drawImage(images.eyeFoo, 0, 80);
	ctx.drawImage(images.folder1, 100, 80);
