这是一种使用promisify和两个帮助函数(to和toAll)来解决承诺的方法。

它以异步方式执行所有操作。

const fs = require('fs');
const { promisify } = require('util');
const to = require('./to');
const toAll = require('./toAll');

const readDirAsync = promisify(fs.readdir);
const rmDirAsync = promisify(fs.rmdir);
const unlinkAsync = promisify(fs.unlink);

/**
    * @author Aécio Levy
    * @function removeDirWithFiles
    * @usage: remove dir with files
    * @param {String} path
    */
const removeDirWithFiles = async path => {
    try {
        const file = readDirAsync(path);
        const [error, files] = await to(file);
        if (error) {
            throw new Error(error)
        }
        const arrayUnlink = files.map((fileName) => {
            return unlinkAsync(`${path}/${fileName}`);
        });
        const [errorUnlink, filesUnlink] = await toAll(arrayUnlink);
        if (errorUnlink) {
            throw new Error(errorUnlink);
        }
        const deleteDir = rmDirAsync(path);
        const [errorDelete, result] = await to(deleteDir);
        if (errorDelete) {
            throw new Error(errorDelete);
        }
    } catch (err) {
        console.log(err)
    }
}; 

有一个模块叫做rimraf (https://npmjs.org/package/rimraf)。它提供了与rm -Rf相同的功能

异步用法:

var rimraf = require("rimraf");
rimraf("/some/directory", function () { console.log("done"); });

同步用法:

rimraf.sync("/some/directory");

//不使用任何第三方lib

const fs = require('fs');
var FOLDER_PATH = "./dirname";
var files = fs.readdirSync(FOLDER_PATH);
files.forEach(element => {
    fs.unlinkSync(FOLDER_PATH + "/" + element);
});
fs.rmdirSync(FOLDER_PATH);

const removeDirWithFiles = async path => {
    try {
        const file = readDirAsync(path);
        const [error, files] = await to(file);
        if (error) {
            throw new Error(error)
        }
        const arrayUnlink = files.map((fileName) => {
            return unlinkAsync(`${path}/${fileName}`);
        });
        const [errorUnlink, filesUnlink] = await toAll(arrayUnlink);
        if (errorUnlink) {
            throw new Error(errorUnlink);

        const [errorDelete, result] = await to(deleteDir);
        if (errorDelete) {
            throw new Error(errorDelete);
        }
    } catch (err) {
        console.log(err)
    }
}; 

事实上的包是rimraf，但这里是我的小异步版本:

const fs = require('fs')
const path = require('path')
const Q = require('q')

function rmdir (dir) {
  return Q.nfcall(fs.access, dir, fs.constants.W_OK)
    .then(() => {
      return Q.nfcall(fs.readdir, dir)
        .then(files => files.reduce((pre, f) => pre.then(() => {
          var sub = path.join(dir, f)
          return Q.nfcall(fs.lstat, sub).then(stat => {
            if (stat.isDirectory()) return rmdir(sub)
            return Q.nfcall(fs.unlink, sub)
          })
        }), Q()))
    })
    .then(() => Q.nfcall(fs.rmdir, dir))
}

return new Promise((resolve, reject) => {
  const fs = require("fs");
  // directory path
  const dir = "your/dir";

  // delete directory recursively <------
  fs.rmdir(dir, { recursive: true }, (err) => {
    if (err) {
      reject(err);
    }
    resolve(`${dir} is deleted!`);
  });
});
