非递归版本

您并没有说要递归地执行，所以我假设您只需要目录的直接子级。

示例代码：

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

fs.readdirSync('your-directory-path')
  .filter((file) => fs.lstatSync(path.join(folder, file)).isFile());

试试这个，它对我有用

import fs from "fs/promises";

const path = "path/to/folder";

export const readDir = async function readDir(path) {

    const files = await fs.readdir(path);

    // array of file names
    console.log(files);
}

与ES7一起使用Promise

与mz/fs的异步使用

mz模块提供了核心节点库的预期版本。使用它们很简单。首先安装库。。。

npm install mz

然后

const fs = require('mz/fs');
fs.readdir('./myDir').then(listing => console.log(listing))
  .catch(err => console.error(err));

或者，您可以在ES7中的异步函数中编写它们：

async function myReaddir () {
  try {
    const file = await fs.readdir('./myDir/');
  }
  catch (err) { console.error( err ) }
};

更新递归列表

一些用户已经指定希望看到递归列表（尽管不在问题中）。。。使用fs promise。它是mz的一个薄包装。

npm install fs-promise;

然后

const fs = require('fs-promise');
fs.walk('./myDir').then(
    listing => listing.forEach(file => console.log(file.path))
).catch(err => console.error(err));

开箱即用

如果您想要一个具有开箱即用的目录结构的对象，我强烈建议您检查目录树。

假设你有这样的结构：

photos
│   june
│   └── windsurf.jpg
└── january
    ├── ski.png
    └── snowboard.jpg

const dirTree = require("directory-tree");
const tree = dirTree("/path/to/photos");

将返回：

{
  path: "photos",
  name: "photos",
  size: 600,
  type: "directory",
  children: [
    {
      path: "photos/june",
      name: "june",
      size: 400,
      type: "directory",
      children: [
        {
          path: "photos/june/windsurf.jpg",
          name: "windsurf.jpg",
          size: 400,
          type: "file",
          extension: ".jpg"
        }
      ]
    },
    {
      path: "photos/january",
      name: "january",
      size: 200,
      type: "directory",
      children: [
        {
          path: "photos/january/ski.png",
          name: "ski.png",
          size: 100,
          type: "file",
          extension: ".png"
        },
        {
          path: "photos/january/snowboard.jpg",
          name: "snowboard.jpg",
          size: 100,
          type: "file",
          extension: ".jpg"
        }
      ]
    }
  ]
}

自定义对象

否则，如果要使用自定义设置创建目录树对象，请查看以下代码段。在这个代码沙盒上可以看到一个活生生的例子。

// my-script.js
const fs = require("fs");
const path = require("path");

const isDirectory = filePath => fs.statSync(filePath).isDirectory();
const isFile = filePath => fs.statSync(filePath).isFile();

const getDirectoryDetails = filePath => {
  const dirs = fs.readdirSync(filePath);
  return {
    dirs: dirs.filter(name => isDirectory(path.join(filePath, name))),
    files: dirs.filter(name => isFile(path.join(filePath, name)))
  };
};

const getFilesRecursively = (parentPath, currentFolder) => {
  const currentFolderPath = path.join(parentPath, currentFolder);
  let currentDirectoryDetails = getDirectoryDetails(currentFolderPath);

  const final = {
    current_dir: currentFolder,
    dirs: currentDirectoryDetails.dirs.map(dir =>
      getFilesRecursively(currentFolderPath, dir)
    ),
    files: currentDirectoryDetails.files
  };

  return final;
};

const getAllFiles = relativePath => {
  const fullPath = path.join(__dirname, relativePath);
  const parentDirectoryPath = path.dirname(fullPath);
  const leafDirectory = path.basename(fullPath);

  const allFiles = getFilesRecursively(parentDirectoryPath, leafDirectory);
  return allFiles;
};

module.exports = { getAllFiles };

然后，您可以简单地执行以下操作：

// another-file.js 

const { getAllFiles } = require("path/to/my-script");

const allFiles = getAllFiles("/path/to/my-directory");

提醒一下：如果您计划对目录中的每个文件执行操作，请尝试vinylfs（流式构建系统gulp使用）。

它只有2行代码：

fs=require('fs')
fs.readdir("./img/", (err,filename)=>console.log(filename))
