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"]

这将起作用，并将结果存储在test.txt文件中，该文件将位于同一目录中

  fs.readdirSync(__dirname).forEach(file => {
    fs.appendFileSync("test.txt", file+"\n", function(err){
    })
})

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()
    }

function getFilesRecursiveSync(dir, fileList, optionalFilterFunction) {
    if (!fileList) {
        grunt.log.error("Variable 'fileList' is undefined or NULL.");
        return;
    }
    var files = fs.readdirSync(dir);
    for (var i in files) {
        if (!files.hasOwnProperty(i)) continue;
        var name = dir + '/' + files[i];
        if (fs.statSync(name).isDirectory()) {
            getFilesRecursiveSync(name, fileList, optionalFilterFunction);
        } else {
            if (optionalFilterFunction && optionalFilterFunction(name) !== true)
                continue;
            fileList.push(name);
        }
    }
}

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']));
