Future web pattern
Alien.js is a design pattern and project structure for building SPA websites with ES modules and GSAP.
The idea is to keep it simple and build websites more like a framework, which is why Rollup is used instead for bundling.
In its design, everything is an ES module, all user interfaces and components follow the same class structure, making it easy to copy-paste from examples and between projects.
Note this design pattern intentionally does not use underscores or private fields, in favour of cleaner code.
import gsap from 'gsap';
export class Logo {
constructor() {
this.element;
this.image;
this.initHTML();
this.addListeners();
this.onResize();
}
addListeners() {
window.addEventListener('resize', this.onResize);
window.addEventListener('orientationchange', this.onResize);
this.element.addEventListener('mouseenter', this.onHover);
this.element.addEventListener('mouseleave', this.onHover);
this.element.addEventListener('click', this.onClick);
}
removeListeners() {
window.removeEventListener('resize', this.onResize);
window.removeEventListener('orientationchange', this.onResize);
this.element.removeEventListener('mouseenter', this.onHover);
this.element.removeEventListener('mouseleave', this.onHover);
this.element.removeEventListener('click', this.onClick);
}

this.element = document.createElement('div');
this.element.classList.add('logo');

this.image = document.createElement('img');
this.image.src = 'assets/images/alienkitty.svg';
