Readme
#Node-watch A fs.watch wrapper to watch files or directories(recursively by default).
npm install node-watch
var watch = require('node-watch');
watch('somedir_or_somefile', function(filename) {
console.log(filename, ' changed.');
});
Some editors will generate temporary files which will cause the callback function to be triggered multiple times.
when watching a single file the callback function will only be triggered one time and then is seem to be unwatched.
Missing an option to watch a directory recursively.
This module currently does not differentiate event like rename
or delete
. Once there is a change, the callback function will be triggered.
recursive
:Watch it recursively or not (defaults to true).
followSymLinks
: Follow symbolic links or not (defaults to false).
maxSymLevel
: The max number of following symbolic links, in order to prevent circular links (defaults to 1).
watch('somedir', { recursive: false, followSymLinks: true }, function(filename) {
console.log(filename, ' changed.');
});
###FAQ
watch(['file1', 'file2'], function(file) {
//
});
Write your own filter function as a higher-order function. For example:
var filter = function(pattern, fn) {
return function(filename) {
if (pattern.test(filename)) {
fn(filename);
}
}
}
// only watch for js files
watch('mydir', filter(/\.js$/, function(filename) {
//
}));
