Custom Builds

As of kontra 6.0.0, custom builds can be achieved by using a module bundler such as Rollup or webpack. Kontra supports ES modules, allowing you to use tree-shaking to only bundle the code you need.

// game.js
import { Sprite, GameLoop } from 'kontra';

let sprite = Sprite({
x: 100,
y: 100,
dx: 2,
width: 20,
height: 40,
color: 'red'
});

let loop = GameLoop({
update() {
 sprite.update();
},
render() {
 sprite.render();
}
});

loop.start();

$ rollup game.js --format iife --file game.bundle.js
