Vanilla JS

import { createNebula } from "@flodlc/nebula";

<div id="nebula-element"></div>

    starsCount: 250,
    starsRotationSpeed: 3,
    nebulasIntensity: 8,
    ...
});
// ... if needed:
nebula.destroy()

React

import { ReactNebula } from "@flodlc/nebula";

export default App = () => {
   return (
       <>
           // With default config
           <ReactNebula/>

           // With custom config
           <ReactNebula config={{
               starsCount: 250,
               starsRotationSpeed: 3,
               nebulasIntensity: 8,
