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())

我从你的问题中假设你不需要目录名，只需要文件。

目录结构示例

animals
├── all.jpg
├── mammals
│   └── cat.jpg
│   └── dog.jpg
└── insects
    └── bee.jpg

步行功能

根据这一要点，Justin Maier将获得积分

如果只需要一个文件路径数组，请使用return_object:false：

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

async function walk(dir) {
    let files = await fs.readdir(dir);
    files = await Promise.all(files.map(async file => {
        const filePath = path.join(dir, file);
        const stats = await fs.stat(filePath);
        if (stats.isDirectory()) return walk(filePath);
        else if(stats.isFile()) return filePath;
    }));

    return files.reduce((all, folderContents) => all.concat(folderContents), []);
}

用法

async function main() {
   console.log(await walk('animals'))
}

输出

[
  "/animals/all.jpg",
  "/animals/mammals/cat.jpg",
  "/animals/mammals/dog.jpg",
  "/animals/insects/bee.jpg"
];

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()
    }

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'))

这是一个TypeScript，可选递归，可选错误日志和异步解决方案。可以为要查找的文件名指定正则表达式。

我使用了fs extra，因为这是对fs的一个简单的超集改进。

import * as FsExtra from 'fs-extra'

/**
 * Finds files in the folder that match filePattern, optionally passing back errors .
 * If folderDepth isn't specified, only the first level is searched. Otherwise anything up
 * to Infinity is supported.
 *
 * @static
 * @param {string} folder The folder to start in.
 * @param {string} [filePattern='.*'] A regular expression of the files you want to find.
 * @param {(Error[] | undefined)} [errors=undefined]
 * @param {number} [folderDepth=0]
 * @returns {Promise<string[]>}
 * @memberof FileHelper
 */
public static async findFiles(
    folder: string,
    filePattern: string = '.*',
    errors: Error[] | undefined = undefined,
    folderDepth: number = 0
): Promise<string[]> {
    const results: string[] = []

    // Get all files from the folder
    let items = await FsExtra.readdir(folder).catch(error => {
        if (errors) {
            errors.push(error) // Save errors if we wish (e.g. folder perms issues)
        }

        return results
    })

    // Go through to the required depth and no further
    folderDepth = folderDepth - 1

    // Loop through the results, possibly recurse
    for (const item of items) {
        try {
            const fullPath = Path.join(folder, item)

            if (
                FsExtra.statSync(fullPath).isDirectory() &&
                folderDepth > -1)
            ) {
                // Its a folder, recursively get the child folders' files
                results.push(
                    ...(await FileHelper.findFiles(fullPath, filePattern, errors, folderDepth))
                )
            } else {
                // Filter by the file name pattern, if there is one
                if (filePattern === '.*' || item.search(new RegExp(filePattern, 'i')) > -1) {
                    results.push(fullPath)
                }
            }
        } catch (error) {
            if (errors) {
                errors.push(error) // Save errors if we wish
            }
        }
    }

    return results
}

从Node v10.10.0开始，可以将fs.readdir和fs.readderSync的新withFileTypes选项与dirent.isDirectory（）函数结合使用，以过滤目录中的文件名。看起来像这样：

fs.readdirSync('./dirpath', {withFileTypes: true})
.filter(item => !item.isDirectory())
.map(item => item.name)

返回的数组的格式为：

['file1.txt', 'file2.txt', 'file3.txt']
