获取目录nodejs中的所有目录

Question

我希望这会是一件简单的事情,但我找不到任何可以做到的事情.

我只想获取给定文件夹/目录中的所有文件夹/目录.

例如:

<MyFolder>
|- SomeFolder
|- SomeOtherFolder
|- SomeFile.txt
|- SomeOtherFile.txt
|- x-directory

我希望得到一个数组:

["SomeFolder", "SomeOtherFolder", "x-directory"]

或上面的路径,如果这是如何服务...

那么上面有什么已经存在的吗？

Answer 1

这是这个答案的一个较短的同步版本,它可以列出当前目录中的所有目录(隐藏或不隐藏):

const { lstatSync, readdirSync } = require('fs')
const { join } = require('path')

const isDirectory = source => lstatSync(source).isDirectory()
const getDirectories = source =>
  readdirSync(source).map(name => join(source, name)).filter(isDirectory)

Answer 2

感谢JavaScript ES6(ES2015)语法功能,它是一个内容:

**同步版**

const { readdirSync, statSync } = require('fs')
const { join } = require('path')

const dirs = p => readdirSync(p).filter(f => statSync(join(p, f)).isDirectory())

Node.js 10+的异步版本(实验性)

const { readdir, stat } = require("fs").promises
const { join } = require("path")

const dirs = async path => {
  let dirs = []
  for (const file of await readdir(path)) {
    if ((await stat(join(path, file))).isDirectory()) {
      dirs = [...dirs, file]
    }
  }
  return dirs
}

Answer 3

使用路径列出目录.

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

Answer 4

递归解决方案

我来到这里寻找一种方法来获取所有子目录及其所有子目录等.基于接受的答案,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))];
}

Answer 5

这应该这样做:

CoffeeScript(同步)

fs = require 'fs'

getDirs = (rootDir) ->
    files = fs.readdirSync(rootDir)
    dirs = []

    for file in files
        if file[0] != '.'
            filePath = "#{rootDir}/#{file}"
            stat = fs.statSync(filePath)

            if stat.isDirectory()
                dirs.push(file)

    return dirs

CoffeeScript(异步)

fs = require 'fs'

getDirs = (rootDir, cb) ->
    fs.readdir rootDir, (err, files) ->
        dirs = []

        for file, index in files
            if file[0] != '.'
                filePath = "#{rootDir}/#{file}"
                fs.stat filePath, (err, stat) ->
                    if stat.isDirectory()
                        dirs.push(file)
                    if files.length == (index + 1)
                        cb(dirs)

JavaScript(异步)

var fs = require('fs');
var getDirs = function(rootDir, cb) { 
    fs.readdir(rootDir, function(err, files) { 
        var dirs = []; 
        for (var index = 0; index < files.length; ++index) { 
            var file = files[index]; 
            if (file[0] !== '.') { 
                var filePath = rootDir + '/' + file; 
                fs.stat(filePath, function(err, stat) {
                    if (stat.isDirectory()) { 
                        dirs.push(this.file); 
                    } 
                    if (files.length === (this.index + 1)) { 
                        return cb(dirs); 
                    } 
                }.bind({index: index, file: file})); 
            }
        }
    });
}

或者,如果您能够使用外部库,则可以使用filehound.它支持回调,承诺和同步调用.

使用承诺:

const Filehound = require('filehound');

Filehound.create()
  .path("MyFolder")
  .directory() // only search for directories
  .find()
  .then((subdirectories) => {
    console.log(subdirectories);
  });

使用回调:

const Filehound = require('filehound');

Filehound.create()
  .path("MyFolder")
  .directory()
  .find((err, subdirectories) => {
    if (err) return console.error(err);

    console.log(subdirectories);
  });

同步通话:

const Filehound = require('filehound');

const subdirectories = Filehound.create()
  .path("MyFolder")
  .directory()
  .findSync();

console.log(subdirectories);

Answer 7

对于 node.js 版本 >= v10.13.0，如果选项设置为，fs.readdirSync将返回一个fs.Dirent对象数组。withFileTypestrue

所以你可以使用，

const fs = require('fs')

const directories = source => fs.readdirSync(source, {
   withFileTypes: true
}).reduce((a, c) => {
   c.isDirectory() && a.push(c.name)
   return a
}, [])

Answer 8

使用 fs-extra，它承诺异步 fs 调用，以及新的 await 异步语法：

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("/")

Answer 9

 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));``
