This is a simple plain vanilla JS file hot-reload checker, It simulates browser hot-reload through a combination of polling and server-sde file checker. EXTREMELY SIMPLE SCript to deploy and use.
Just add one line of code to the bottom of any web page that you want to re-load on a file change.
<script type="text/javascript" src="hotreload.js"></script>
This temporary placeholder is changed by a cron script to simulate a user editing the file
-- Used to simulate a user workign on the file.
