下面是@SharpCoder的答案的异步版本

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

function deleteFile(dir, file) {
    return new Promise(function (resolve, reject) {
        var filePath = path.join(dir, file);
        fs.lstat(filePath, function (err, stats) {
            if (err) {
                return reject(err);
            }
            if (stats.isDirectory()) {
                resolve(deleteDirectory(filePath));
            } else {
                fs.unlink(filePath, function (err) {
                    if (err) {
                        return reject(err);
                    }
                    resolve();
                });
            }
        });
    });
};

function deleteDirectory(dir) {
    return new Promise(function (resolve, reject) {
        fs.access(dir, function (err) {
            if (err) {
                return reject(err);
            }
            fs.readdir(dir, function (err, files) {
                if (err) {
                    return reject(err);
                }
                Promise.all(files.map(function (file) {
                    return deleteFile(dir, file);
                })).then(function () {
                    fs.rmdir(dir, function (err) {
                        if (err) {
                            return reject(err);
                        }
                        resolve();
                    });
                }).catch(reject);
            });
        });
    });
};

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))
}

我通常不复活旧线程，但这里有很多关于搅动和没有rimraf的答案，这些对我来说似乎都太复杂了。

首先，在现代Node (>= v8.0.0)中，你可以只使用节点核心模块来简化过程，完全异步，并在5行函数中并行化文件的解链接，并且仍然保持可读性:

const fs = require('fs');
const path = require('path');
const { promisify } = require('util');
const readdir = promisify(fs.readdir);
const rmdir = promisify(fs.rmdir);
const unlink = promisify(fs.unlink);

exports.rmdirs = async function rmdirs(dir) {
  let entries = await readdir(dir, { withFileTypes: true });
  await Promise.all(entries.map(entry => {
    let fullPath = path.join(dir, entry.name);
    return entry.isDirectory() ? rmdirs(fullPath) : unlink(fullPath);
  }));
  await rmdir(dir);
};

另一方面，路径遍历攻击的保护不适合此函数，因为

It is out of scope based on the Single Responsibility Principle. Should be handled by the caller not this function. This is akin to the command-line rm -rf in that it takes an argument and will allow the user to rm -rf / if asked to. It would be the responsibility of a script to guard not the rm program itself. This function would be unable to determine such an attack since it does not have a frame of reference. Again that is the responsibility of the caller who would have the context of intent which would provide it a reference to compare the path traversal. Sym-links are not a concern as .isDirectory() is false for sym-links and are unlinked not recursed into.

最后但并非最不重要的是，有一种罕见的竞争条件，即在运行递归时，如果在正确的时间在脚本之外取消链接或删除其中一个条目，则递归可能会出错。由于这种情况在大多数环境中并不典型，因此可能会被忽略。然而，如果需要(对于一些边缘情况)，这个问题可以通过下面这个稍微复杂一点的例子来缓解:

exports.rmdirs = async function rmdirs(dir) {
  let entries = await readdir(dir, { withFileTypes: true });
  let results = await Promise.all(entries.map(entry => {
    let fullPath = path.join(dir, entry.name);
    let task = entry.isDirectory() ? rmdirs(fullPath) : unlink(fullPath);
    return task.catch(error => ({ error }));
  }));
  results.forEach(result => {
    // Ignore missing files/directories; bail on other errors
    if (result && result.error.code !== 'ENOENT') throw result.error;
  });
  await rmdir(dir);
};

编辑:使isDirectory()成为一个函数。最后删除实际目录。修复丢失的递归。

在Node.js的最新版本(12.10.0或更高版本)中，rmdir样式函数fs.rmdir()、fs.rmdirSync()和fs.promises.rmdir()有一个新的实验性选项递归，允许删除非空目录，例如:

fs.rmdir(path, { recursive: true });

GitHub上的相关PR: https://github.com/nodejs/node/pull/29168

const fs = require("fs")
const path = require("path")

let _dirloc = '<path_do_the_directory>'

if (fs.existsSync(_dirloc)) {
  fs.readdir(path, (err, files) => {
    if (!err) {
      for (let file of files) {
        // Delete each file
        fs.unlinkSync(path.join(_dirloc, file))
      }
    }
  })
  // After the 'done' of each file delete,
  // Delete the directory itself.
  if (fs.unlinkSync(_dirloc)) {
    console.log('Directory has been deleted!')
  }
}

❄️您可以使用graph-fs

directory.delete()
