There are basically two ways of accomplishing this. In an async environment you'll notice that there are two kinds of loops: serial and parallel. A serial loop waits for one iteration to complete before it moves onto the next iteration - this guarantees that every iteration of the loop completes in order. In a parallel loop, all the iterations are started at the same time, and one may complete before another, however, it is much faster than a serial loop. So in this case, it's probably better to use a parallel loop because it doesn't matter what order the walk completes in, just as long as it completes and returns the results (unless you want them in order).

一个平行循环看起来是这样的:

var fs = require('fs');
var path = require('path');
var walk = function(dir, done) {
  var results = [];
  fs.readdir(dir, function(err, list) {
    if (err) return done(err);
    var pending = list.length;
    if (!pending) return done(null, results);
    list.forEach(function(file) {
      file = path.resolve(dir, file);
      fs.stat(file, function(err, stat) {
        if (stat && stat.isDirectory()) {
          walk(file, function(err, res) {
            results = results.concat(res);
            if (!--pending) done(null, results);
          });
        } else {
          results.push(file);
          if (!--pending) done(null, results);
        }
      });
    });
  });
};

一个串行循环看起来像这样:

var fs = require('fs');
var path = require('path');
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 = path.resolve(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();
        }
      });
    })();
  });
};

并且在你的主目录中测试它(警告:如果你的主目录中有很多东西，结果列表将会非常大):

walk(process.env.HOME, function(err, results) {
  if (err) throw err;
  console.log(results);
});

编辑:改进的示例。

使用node-dir可以生成您想要的输出

var dir = require('node-dir');

dir.files(__dirname, function(err, files) {
  if (err) throw err;
  console.log(files);
  //we have an array of files now, so now we can iterate that array
  files.forEach(function(path) {
    action(null, path);
  })
});

我最近编写了这个代码，并认为在这里分享它是有意义的。代码使用了异步库。

var fs = require('fs');
var async = require('async');

var scan = function(dir, suffix, callback) {
  fs.readdir(dir, function(err, files) {
    var returnFiles = [];
    async.each(files, function(file, next) {
      var filePath = dir + '/' + file;
      fs.stat(filePath, function(err, stat) {
        if (err) {
          return next(err);
        }
        if (stat.isDirectory()) {
          scan(filePath, suffix, function(err, results) {
            if (err) {
              return next(err);
            }
            returnFiles = returnFiles.concat(results);
            next();
          })
        }
        else if (stat.isFile()) {
          if (file.indexOf(suffix, file.length - suffix.length) !== -1) {
            returnFiles.push(filePath);
          }
          next();
        }
      });
    }, function(err) {
      callback(err, returnFiles);
    });
  });
};

你可以这样使用它:

scan('/some/dir', '.ext', function(err, files) {
  // Do something with files that ends in '.ext'.
  console.log(files);
});

我修改了老特雷弗的承诺为蓝鸟工作的基础上的答案

var fs = require('fs'),
    path = require('path'),
    Promise = require('bluebird');

var readdirAsync = Promise.promisify(fs.readdir);
var statAsync = Promise.promisify(fs.stat);
function walkFiles (directory) {
    var results = [];
    return readdirAsync(directory).map(function(file) {
        file = path.join(directory, file);
        return statAsync(file).then(function(stat) {
            if (stat.isFile()) {
                return results.push(file);
            }
            return walkFiles(file).then(function(filesInDir) {
                results = results.concat(filesInDir);
            });
        });
    }).then(function() {
        return results;
    });
}

//use
walkDir(__dirname).then(function(files) {
    console.log(files);
}).catch(function(e) {
    console.error(e); {
});

看看装载机 https://npmjs.org/package/loaddir

npm无处不在

  loaddir = require('loaddir')

  allJavascripts = []
  loaddir({
    path: __dirname + '/public/javascripts',
    callback: function(){  allJavascripts.push(this.relativePath + this.baseName); }
  })

如果还需要扩展名，可以使用fileName而不是baseName。

一个额外的好处是，它也会监视文件，并再次调用回调。有大量的配置选项使它非常灵活。

我只是在短时间内用加载器从红宝石重造了守卫宝石

如果你想使用npm包，扳手是很好的选择。

var wrench = require("wrench");

var files = wrench.readdirSyncRecursive("directory");

wrench.readdirRecursive("directory", function (error, files) {
    // live your dreams
});

编辑(2018): 作者在2015年弃用了这个包:

扳手.js已弃用，并且在相当长的一段时间内没有更新。我强烈建议使用fs-extra来执行任何额外的文件系统操作。
