It monitors a directory for change (using notify facility provided by the OS), upon change, will execute a given command given by command line arg `-command`. If any browser connected, it will try to refresh the browser too.
flag.StringVar(&path, "watch", ".", "path to be watched")
flag.StringVar(&command, "command", "echo", "path to be watched")
This is going to be a great help towards that; props to the author.
"nodemon has three potential methods it uses to look for file changes. First, it polls using the find command to search for files modified within the last second. This method works on systems with a BSD based find (Mac, for example)."
Especially on Mac OSX why would you prefer to use an external command like find instead of using Kqueue? I wonder if find is the right tool for that. And I wonder again why only on BSD-based systems when linux also has find.
Gotta read a bit more about that.
fyi, this is how nodemon is doing file checking:
find -L /dev/null -type f -mtime -1s -print
