Drop-in replacement for filewatcher that watches directories instead of individual files in order to use less file handles.

About

Watching files with Node.JS is still a mess. While filewatcher addresses most of these issues, one problem still remains: OS X uses one file handle for each fs.watch() call. Since the maximum number of file handles is quite low by default, you quickly run into EMFILE errors.

To use less file handles, fwatch uses dirwatcher (which in turn uses filewatcher under the hood) to watches a file's directory instead.

Usage

var fwatch = require('fwatch');

var w = fwatch();

// watch a file
w.add(file);

w.on('change', function(file, stat) {
  console.log('File modified:', file);
  if (stat.deleted) console.log('deleted!');
});

w.on('error', function(err) {
  console.log(err);
});

// stop watching a given file
w.remove(file);

// ... stop watching all watched files
w.removeAll();
