递归解决方案

我来这里是为了寻找一种方法来获取所有子目录，以及它们的所有子目录，等等。在这个公认的答案的基础上，我写道:

const fs = require('fs');
const path = require('path');

function flatten(lists) {
  return lists.reduce((a, b) => a.concat(b), []);
}

function getDirectories(srcpath) {
  return fs.readdirSync(srcpath)
    .map(file => path.join(srcpath, file))
    .filter(path => fs.statSync(path).isDirectory());
}

function getDirectoriesRecursive(srcpath) {
  return [srcpath, ...flatten(getDirectories(srcpath).map(getDirectoriesRecursive))];
}

对于getDirectories的异步版本，你需要async模块:

var fs = require('fs');
var path = require('path');
var async = require('async'); // https://github.com/caolan/async

// Original function
function getDirsSync(srcpath) {
  return fs.readdirSync(srcpath).filter(function(file) {
    return fs.statSync(path.join(srcpath, file)).isDirectory();
  });
}

function getDirs(srcpath, cb) {
  fs.readdir(srcpath, function (err, files) {
    if(err) { 
      console.error(err);
      return cb([]);
    }
    var iterator = function (file, cb)  {
      fs.stat(path.join(srcpath, file), function (err, stats) {
        if(err) { 
          console.error(err);
          return cb(false);
        }
        cb(stats.isDirectory());
      })
    }
    async.filter(files, iterator, cb);
  });
}

另一种递归方法

感谢Mayur了解我的withFileTypes。我写了下面的代码来递归地获取特定文件夹的文件。可以很容易地修改它以只获取目录。

const getFiles = (dir, base = '') => readdirSync(dir, {withFileTypes: true}).reduce((files, file) => {
    const filePath = path.join(dir, file.name)
    const relativePath = path.join(base, file.name)
    if(file.isDirectory()) {
        return files.concat(getFiles(filePath, relativePath))
    } else if(file.isFile()) {
        file.__fullPath = filePath
        file.__relateivePath = relativePath
        return files.concat(file)
    }
}, [])

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);
    });
});

你可以使用graph-fs

const {Node} = require("graph-fs");
const directory = new Node("/path/to/directory");

const subDirectories = directory.children.filter(child => child.is.directory);

使用fs-extra，承诺async fs调用，以及新的await async语法:

const fs = require("fs-extra");

async function getDirectories(path){
    let filesAndDirectories = await fs.readdir(path);

    let directories = [];
    await Promise.all(
        filesAndDirectories.map(name =>{
            return fs.stat(path + name)
            .then(stat =>{
                if(stat.isDirectory()) directories.push(name)
            })
        })
    );
    return directories;
}

let directories = await getDirectories("/")
