Dang it – didn't quite get everything updated. But a @chriscoyier post referenced Turbowatch and Live.js as a simple file watcher/browser reloader combo.
I want something simpler than Turbowatch though, and more modern than Live.js.
Live.js also didn't work with Laravel Valet. 😢
BUT… I got it all working! It's 55 lines of shell script and 10k of modernised JS (uncompressed). I will build it into my small static site template and write up soon!!
