watchdirectory
Similar to node fs.watchFile but watches a directory recursively and lets you unwatch as well
Install
npm install watchdirectory
Purpose
This module provides the ability to recursively watch a directory for changes. Unlike similar modules, this one can unwatch as well.
watchdirectory.watchDirectory(root, [options,] callback)
The first argument is the directory root you want to watch.
The options object is passed to fs.watchFile but can also be used to provide additional watchDirectory specific options:
'initial'
- Defaults to true. If true then we notify the callback of files during initial directory walk.'recursive'
- Defaults to true. Controls the depth of our directory walk.'include'
- Can be a function or RegExp or string. If it's a string then that will be considered an extension to check. Your callback will only be notified about files that match.'exclude'
- Can be a function or RegExp or string. If it's a string then that will be considered an extension to check. Your callback will not be notified about files that match.
var unwatch = watchdirectory.watchDirectory('src', {filter:'.js'}, function (filename, curr, prev, change) { if (change == 'initial') { // filename found during initial pass } else if (change == 'created') { // filename is a new file } else if (change == 'deleted') { // filename was removed } else if (change == 'modified') { // filename was changed } }); // later on to unwatch, just call the previously returned function unwatch();
