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 smokybg

Usage

<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
