我想写一个 node .js脚本，监视文件目录中的更改，然后打印更改的文件.如何修改此脚本，使其监视目录(而不是单个文件)，并在目录中的文件发生更改时打印它们的名称？
var fs = require('fs'),
sys = require('sys');
var file = '/home/anderson/Desktop/fractal.png'; //this watches a file, but I want to watch a directory instead
fs.watchFile(file, function(curr, prev) {
alert("File was modified."); //is there some way to print the names of the files in the directory as they are modified?
});
试试Chokidar:
var chokidar = require('chokidar');
var watcher = chokidar.watch('file or dir', {ignored: /^\./, persistent: true});
watcher
.on('add', function(path) {console.log('File', path, 'has been added');})
.on('change', function(path) {console.log('File', path, 'has been changed');})
.on('unlink', function(path) {console.log('File', path, 'has been removed');})
.on('error', function(error) {console.error('Error happened', error);})
Chokidar解决了一些只使用fs查看文件的跨平台问题.
