How to use it

You should wait for the document ready event and call the init method to detect breakpoint changes. We expose one global variable available everywhere: bsBreakpoints

In browser with UMD version:

document.addEventListener('DOMContentLoaded', function () {
  const detector = new bsBreakpoints.BreakpointDetector();
})

Use it with npm

import { BreakpointDetector } from 'bs-breakpoints';

For UMD examples check out this file.

This library is ES and UMD ready so you can use it everywhere.
