获取所有分区中的文件

const fs=require('fs');

function getFiles (dir, files_){
    files_ = files_ || [];
    var files = fs.readdirSync(dir);
    for (var i in files){
        var name = dir + '/' + files[i];
        if (fs.statSync(name).isDirectory()){
            getFiles(name, files_);
        } else {
            files_.push(name);
        }
    }
    return files_;
}

console.log(getFiles('path/to/dir'))

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。

我最近为此开发了一个工具，它可以做到这一点。。。它异步获取目录并返回项目列表。您可以获取目录、文件或两者，首先是文件夹。如果不想获取整个文件夹，也可以对数据进行分页。

这是一个异步递归版本。

    function ( path, callback){
     // the callback gets ( err, files) where files is an array of file names
     if( typeof callback !== 'function' ) return
     var
      result = []
      , files = [ path.replace( /\/\s*$/, '' ) ]
     function traverseFiles (){
      if( files.length ) {
       var name = files.shift()
       fs.stat(name, function( err, stats){
        if( err ){
         if( err.errno == 34 ) traverseFiles()
    // in case there's broken symbolic links or a bad path
    // skip file instead of sending error
         else callback(err)
        }
        else if ( stats.isDirectory() ) fs.readdir( name, function( err, files2 ){
         if( err ) callback(err)
         else {
          files = files2
           .map( function( file ){ return name + '/' + file } )
           .concat( files )
          traverseFiles()
         }
        })
        else{
         result.push(name)
         traverseFiles()
        }
       })
      }
      else callback( null, result )
     }
     traverseFiles()
    }

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']));
