hound

hound - directory tree watcher for node.js

Cross platform directory tree watcher that works, even on Windows

The philosophy of hound is:

• Be reliable, work on every platform
• Be fast
• Be simple

hound is designed to be very reliable, fast, and simple. There are no runtime dependencies outside of the standard node.js libraries. There is a development dependency on Jasmine, which is required to run the tests.

Installation

Install using npm:

npm install hound

Because hound has no runtime dependencies, it is also possible to download the library manually and require it directly.

Usage

hound = require('hound')
 
// Create a directory tree watcher.
watcher = hound.watch('/tmp')
 
// Create a file watcher.
watcher = hound.watch('/tmp/file.txt')
 
// Add callbacks for file and directory events.  The change event only applies
// to files.
watcher.on('create', function(file, stats) {
  console.log(file + ' was created')
})
watcher.on('change', function(file, stats) {
  console.log(file + ' was changed')
})
watcher.on('delete', function(file) {
  console.log(file + ' was deleted')
})
 
// Unwatch specific files or directories.
watcher.unwatch('/tmp/another_file')
 
// Unwatch all watched files and directories.
watcher.clear()

Testing

To run the tests, use npm test. The tests work on actual directory trees that are generated in the tmp directory.
