ref
When called, requests that the Node.js event loop not exit so long as the fs.FSWatcher
is active. Calling watcher.ref()
multiple times will have no effect.
By default, all fs.FSWatcher
objects are "ref'ed", making it normally unnecessary to call watcher.ref()
unless watcher.unref()
had been called previously.
