Question

我无法从此处获取序列示例，但我无法提供链接（？）：

NodeJS: How would one watch a large amount of files/folders on the server side for updates?

var fs = require('fs');
var walk = function(dir, done) {
  var results = [];
  fs.readdir(dir, function(err, list) {
    if (err) return done(err);
    var i = 0;
    (function next() {
      var file = list[i++];
      if (!file) return done(null, results);
      file = dir + '/' + file;
      fs.stat(file, function(err, stat) {
        if (stat && stat.isDirectory()) {
          walk(file, function(err, res) {
            results = results.concat(res);
            next();
          });
        } else {
          results.push(file);
          next();
        }
      });
    })();
  });
};

我试过这个来调用函数，但我不确定它需要什么参数。有人可以建议吗？

//walk(process.env.HOME, function(err, results) {
walk("C:\", function(err, results) {
  if (err) throw err;
  console.log(results);
});

我得到的错误是

module.js:437
  var compiledWrapper = runInThisContext(wrapper, filename, true);
                        ^
SyntaxError: Unexpected token ILLEGAL

逃离\。使用"C:\\"而非"C:\"。

node.js fs.readdir递归目录搜索[2]
