smokybg v0.1.1
Smokybg
This is an analog of waterpipe.js jQuery plugin, but rewritten in typescript and usable as a common npm module with types (not perfectly typed tho)
Install
npm i smokybgUsage
<canvas id="smoky-wrapper" style="width: 100%; height: 100%;">Your browser does not support HTML5 canvas.</canvas>import { Smoke } from 'smokybg';
const element = document.getElementById('smoky-wrapper');
const options = {
kek: 'lol'
};
new Smoke(element, options);Support
If anyone will use this- I will provide wider documentation for this and make a better API
