# fsevents [](https://nodei.co/npm/fsevents/)
|
||
|
|
|
||
|
|
Native access to OS X FSEvents in [Node.js](http://nodejs.org/)
|
||
|
|
|
||
|
|
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](https://www.npmjs.com/package/chokidar).
|
||
|
|
|
||
|
|
* [Module Site & GitHub](https://github.com/strongloop/fsevents)
|
||
|
|
* [NPM Page](https://npmjs.org/package/fsevents)
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
$ npm install fsevents
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
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
|
||
|
|
```
|
||
|
|
|
||
|
|
### Events
|
||
|
|
|
||
|
|
* *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:
|
||
|
|
|
||
|
|
```js
|
||
|
|
{
|
||
|
|
"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>
|
||
|
|
}
|
||
|
|
```
