Native access to OS X FSEvents in Node.js
The FSEvents API in OS X allows applications to register for notifications of changes to a given directory tree. It is a very fast and lightweight alternative to kqueue.
This is a low-level library. For a cross-compatible file watching module that uses fsevents, check out Chokidar.
$ npm install fsevents
var fsevents = require('fsevents');
var watcher = fsevents(__dirname);
watcher.on('fsevent', function(path, flags, id) { }); // RAW Event as emitted by OS-X
watcher.on('change', function(path, info) { }); // Common Event for all changes
watcher.start() // To start observation
watcher.stop() // To end observation- fsevent - RAW Event as emitted by OS-X
- change - Common Event for all changes
- created - A File-System-Item has been created
- deleted - A File-System-Item has been deleted
- modified - A File-System-Item has been modified
- moved-out - A File-System-Item has been moved away from this location
- moved-in - A File-System-Item has been moved into this location
All events except fsevent take an info object as the second parameter of the callback. The structure of this object is:
{
"event": "<event-type>",
"id": <eventi-id>,
"path": "<path-that-this-is-about>",
"type": "<file|directory|symlink>",
"changes": {
"inode": true, // Has the iNode Meta-Information changed
"finder": false, // Has the Finder Meta-Data changed
"access": false, // Have the access permissions changed
"xattrs": false // Have the xAttributes changed
},
"flags": <raw-flags>
