I spent some time digging around in https://github.com/spf13/hugo/tree/master/livereload today to see if it would trigger anything for me, but so I’m a bit out of my depth with go
(tbh, I don’t even understand how the main app invokes the code in this area).
I do see where the port is coming from, in the compressed JS file it does this.port = ...
, but I don’t see a reference to that number anywhere else in the repo.
