Simple wrapper around fs.watch that falls back to fs.watchFile when it runs
out of file handles.
This module is used by node-dev and instant.
var filewatcher = require('filewatcher')
// the default options
var opts = {
interval: 1000, // if we need to poll, do it every 1000ms
persistent: true // don't end the process while files are watched
}
var watcher = filewatcher(opts)
// watch a file
watcher.add(file)
watcher.on('change', function(file, mtime) {
console.log('File modified: %s', file)
if (mtime == -1) console.log('deleted')
})
watcher.on('fallback', function(limit) {
console.log('Ran out of file handles after watching %s files.', limit)
console.log('Falling back to polling which uses more CPU.')
console.log('Run ulimit -n 10000 to increase the limit for open files.')
})
watcher.remove(file)
watcher.removeAll()Copyright (c) 2013 Felix Gnass
