"""Use inotify to watch a directory and execute a command on file change.

Watch for any file change below current directory (using inotify via pyinotify)
and execute the given command on file change.

Just using inotify-tools `while inotifywait -r -e close_write .; do something; done`
has many issues which are fixed by this tools:
 * If your editor creates a backup before writing the file, it'll trigger multiple times.
 * If your directory structure is deep, it'll have to reinitialize inotify after each change.

The final result: require() any module on npm in your browser console with browserify

This article is written to explain how the above gif works in the chrome (and other) browser consoles. A quick disclaimer: this whole thing is a huge hack, it shouldn't be used for anything seriously, and there are probably much better ways of accomplishing the same.

Update: There are much better ways of accomplishing the same, and the script has been updated to use a much simpler method pulling directly from browserify-cdn. See this thread for details: https://github.com/mathisonian/requirify/issues/5

The EventSource API

The EventSource interface is used to receive server-sent events. It connects to a server over HTTP and receives events in text/event-stream format without closing the connection.

https://developer.mozilla.org/en-US/docs/Web/API/EventSource

Last-Event-ID

Setting an ID lets the browser keep track of the last event fired so that if, the connection to the server is dropped, a special HTTP header (Last-Event-ID) is set with the new request.
