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){
    })
})

如果有人还在搜索这个，我会这样做：

从“fs”导入fs；从“path”导入路径；const getAllFiles=目录=>fs.readdirSync（dir）.reduce（（files，file）=>{常量名称=路径.连接（目录，文件）；const isDirectory=fs.statSync（名称）.isDirectory（）；return isDirectory？[…file，…getAllFiles（名称）]：[…files，名称]；}, []);

它的工作对我很好

它只有2行代码：

fs=require('fs')
fs.readdir("./img/", (err,filename)=>console.log(filename))

图像：

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']

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();
}

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'

/**

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)
                }
            }

                errors.push(error) // Save errors if we wish
            }
        }
    }

    return results
