About ----- Synchronizes content of a directory with webclients using socket.io. How it works ------------ 1) Clients connects to server, which sends current filelist. 2) Server watches a directory for changes. 3) On changes (file is added or removed), send notification to clients. Flaws/Todo ---------- Initial plan was to use inotify for watching directory, but turned out to be a hassle to learn; so did a polling fs.readdir(). This should be switched back to the inital plan.
