night.js

At the beginning install the library in your project via npm or Yarn:

$ npm install night.js
$ yarn add night.js

Connect using script tag in HTML:

<script src="/directory/to/library/folder/night.js"></script>

Or CommonJS/ES6 import:

const Night = require('night.js'); // CommonJS
import Night from 'night.js'; // ES6

Next use library with:

• Vanilla JavaScript e.g:

const night = new Night({
  // options...
});

• Switch between light and dark mode:

night.toggle();

• Switch mode automatically (based on time, location and sun position):

night.auto();

• Reset localStorage data:

night.reset();
