While building my web app in Angularjs and Go, I was spending a lot of time re-starting and refreshing the server and the browser. So I went on a hunt for programs out there which could help me automate this process. After much head banging and tinkering, I have a fairly ok setup now.
Http-Watcher: Reloads the html/css/js files.
GoWatch: Rebuilds and runs .go files.
Match that with Sublime Text 2( Go Sublime plugin) and you have a killer setup. Well, unless there is a secret tool I don't about yet.
