var getDirectories = (rootdir , cb) => {
    fs.readdir(rootdir, (err, files) => {
        if(err) throw err ;
        var dirs = files.map(filename => path.join(rootdir,filename)).filter( pathname => fs.statSync(pathname).isDirectory());
        return cb(dirs);
    })

 }
 getDirectories( myDirectories => console.log(myDirectories));``

函数式编程

const fs = require('fs')
const path = require('path')
const R = require('ramda')

const getDirectories = pathName => {
    const isDirectory = pathName => fs.lstatSync(pathName).isDirectory()
    const mapDirectories = pathName => R.map(name => path.join(pathName, name), fs.readdirSync(pathName))
    const filterDirectories = listPaths => R.filter(isDirectory, listPaths)

    return {
        paths:R.pipe(mapDirectories)(pathName),
        pathsFiltered: R.pipe(mapDirectories, filterDirectories)(pathName)
    }
}

使用路径列出目录。

function getDirectories(path) {
  return fs.readdirSync(path).filter(function (file) {
    return fs.statSync(path+'/'+file).isDirectory();
  });
}

这个答案的CoffeeScript版本，有适当的错误处理:

fs = require "fs"
{join} = require "path"
async = require "async"

get_subdirs = (root, callback)->
    fs.readdir root, (err, files)->
        return callback err if err
        subdirs = []
        async.each files,
            (file, callback)->
                fs.stat join(root, file), (err, stats)->
                    return callback err if err
                    subdirs.push file if stats.isDirectory()
                    callback null
            (err)->
                return callback err if err
                callback null, subdirs

取决于async

或者，使用一个模块! (所有东西都有模块。[引文需要])

以防其他人从网络搜索到这里，并且已经在他们的依赖列表中有Grunt，这个问题的答案变得微不足道。以下是我的解决方案:

/**
 * Return all the subfolders of this path
 * @param {String} parentFolderPath - valid folder path
 * @param {String} glob ['/*'] - optional glob so you can do recursive if you want
 * @returns {String[]} subfolder paths
 */
getSubfolders = (parentFolderPath, glob = '/*') => {
    return grunt.file.expand({filter: 'isDirectory'}, parentFolderPath + glob);
}

使用fs, path模块可以获取文件夹。这使用承诺。如果你想要填充，你可以将isDirectory()更改为isFile() Nodejs——fs——fs. stats。最后，你可以得到文件'name file'extname等Nodejs——Path

var fs = require("fs"),
path = require("path");
//your <MyFolder> path
var p = "MyFolder"
fs.readdir(p, function (err, files) {
    if (err) {
        throw err;
    }
    //this can get all folder and file under  <MyFolder>
    files.map(function (file) {
        //return file or folder path, such as **MyFolder/SomeFile.txt**
        return path.join(p, file);
    }).filter(function (file) {
        //use sync judge method. The file will add next files array if the file is directory, or not. 
        return fs.statSync(file).isDirectory();
    }).forEach(function (files) {
        //The files is array, so each. files is the folder name. can handle the folder.
        console.log("%s", files);
    });
});
