If you wish to skip the modular build and NOT use npm you can use the vanilla build like so:

CDN

<script src="https://unpkg.com/@wayfu/simple-wapi@latest/dist/index.min.js"></script>

How to use it:

/** Initiate WAPI and store it into a variable */
/** Local Variable */
let WwJS = WAPI.init(window);

/** or Global variable */
window.WwJS = WAPI.init(window);

You need 1 parameter for initiating WAPI. The parameter should be a window instance of the page. You can use this script to inject the WhatsApp Web on the browser too.
