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");

我通常使用：FS Extra。

const fileNameArray = Fse.readdir('/some/path');

结果：

[
  "b7c8a93c-45b3-4de8-b9b5-a0bf28fb986e.jpg",
  "daeb1c5b-809f-4434-8fd9-410140789933.jpg"
]

采用@湖南罗斯托米扬的一般方法，使其更加简洁，并添加了excludeDirs论点。使用includeDirs进行扩展很简单，只需遵循相同的模式：

import * as fs from 'fs';
import * as path from 'path';

function fileList(dir, excludeDirs?) {
    return fs.readdirSync(dir).reduce(function (list, file) {
        const name = path.join(dir, file);
        if (fs.statSync(name).isDirectory()) {
            if (excludeDirs && excludeDirs.length) {
                excludeDirs = excludeDirs.map(d => path.normalize(d));
                const idx = name.indexOf(path.sep);
                const directory = name.slice(0, idx === -1 ? name.length : idx);
                if (excludeDirs.indexOf(directory) !== -1)
                    return list;
            }
            return list.concat(fileList(name, excludeDirs));
        }
        return list.concat([name]);
    }, []);
}

示例用法：

console.log(fileList('.', ['node_modules', 'typings', 'bower_components']));

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）。

获取排序的文件名。您可以基于特定扩展名（如“.txt”、“.jpg”等）过滤结果。

import * as fs from 'fs';
import * as Path from 'path';

function getFilenames(path, extension) {
    return fs
        .readdirSync(path)
        .filter(
            item =>
                fs.statSync(Path.join(path, item)).isFile() &&
                (extension === undefined || Path.extname(item) === extension)
        )
        .sort();
}

如果上面的许多选项看起来太复杂，或者不是您想要的，这里是另一种使用node-dir的方法https://github.com/fshost/node-dir

npm install node-dir

下面是一个somple函数，用于列出在子目录中搜索的所有.xml文件

import * as nDir from 'node-dir' ;

listXMLs(rootFolderPath) {
    let xmlFiles ;

    nDir.files(rootFolderPath, function(err, items) {
        xmlFiles = items.filter(i => {
            return path.extname(i) === '.xml' ;
        }) ;
        console.log(xmlFiles) ;       
    });
}
