Directory watcher and Total Size reported

watcher.js

var chokidar = require('chokidar');
var dir = '.';
var du = require('du');
var watcher = chokidar.watch(dir, {ignored: /[\/\\]\./});

function getSize()
{
  du(dir, function (err, size) {
  console.log('The current size of ' + dir + ' is:', size, 'bytes');
});
}



watcher
  .on('change', function(path) {
    console.log('File', path, 'has been changed');
    getSize();
   })
  .on('unlink', function(path) {
    console.log('File', path, 'has been removed');
    getSize();
 })
 .on('add', function(path) {
   //console.log('File', path, 'has been added');
   // Deliberately leaving this commented out to avoid wall of initial spam!!
})
  .on('unlinkDir', function(path) {
    console.log('Directory', path, 'has been removed');
    getSize();
  });

watcher.on('all', function(event, path) {
  console.log(event, path);
});

Is also valid for a catch all, the gist above gives more fine grained control and can minimise noise.
