如果有人：

只想列出项目本地子文件夹中的文件名（不包括目录）

✅ 无其他依赖项✅ 1功能✅ 规格化路径（Unix与Windows）

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

/**
 * @param {string} relativeName "resources/foo/goo"
 * @return {string[]}
 */
const listFileNames = (relativeName) => {
  try {
    const folderPath = path.join(process.cwd(), ...relativeName.split("/"));
    return fs
      .readdirSync(folderPath, { withFileTypes: true })
      .filter((dirent) => dirent.isFile())
      .map((dirent) => dirent.name.split(".")[0]);
  } catch (err) {
    // ...
  }
};

listFileNames("resources/countries") #=> ["usa", "japan", "gb"]

我的单行代码：

const fs = require("fs")
const path = 'somePath/'

const filesArray = fs.readdirSync(path).filter(file => fs.lstatSync(path+file).isFile())

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");

您可以使用fs.readdir或fs.readderSync方法。fs包含在Node.js核心中，因此不需要安装任何东西。

fs.加法器

const testFolder = './tests/';
const fs = require('fs');

fs.readdir(testFolder, (err, files) => {
  files.forEach(file => {
    console.log(file);
  });
});

fs.readder同步

const testFolder = './tests/';
const fs = require('fs');

fs.readdirSync(testFolder).forEach(file => {
  console.log(file);
});

这两种方法的区别在于，第一种方法是异步的，因此您必须提供一个回调函数，该函数将在读取过程结束时执行。

第二个是同步的，它将返回文件名数组，但它将停止代码的任何进一步执行，直到读取过程结束。

但是，上面的答案不会对目录执行递归搜索。以下是我对递归搜索所做的操作（使用node walk:npm install walk）

var walk    = require('walk');
var files   = [];

// Walker options
var walker  = walk.walk('./test', { followLinks: false });

walker.on('file', function(root, stat, next) {
    // Add this file to the list of files
    files.push(root + '/' + stat.name);
    next();
});

walker.on('end', function() {
    console.log(files);
});

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());
