方法删除非空目录

rmdir(path,{recursive:true,force:true}
rm(path,{recursive:true,force:true}

将工作

代码片段:

const fsp = require("fs/promises");

deleteDirRecursively("./b");
removeRecursively("./BCD/b+");

async function deleteDirRecursively(dirPath) {
  try {
    // fsPromises.rmdir() on a file (not a directory) results in the promise being rejected
    // with an ENOENT error on Windows and an ENOTDIR error on POSIX.
    // To get a behavior similar to the rm -rf Unix command,
    // use fsPromises.rm() with options { recursive: true, force: true }.
    //will not thorw error if dir is empty
    //will thow error if dir is not present
    await fsp.rmdir(dirPath, { recursive: true, force: true });
    console.log(dirPath, "deleted successfully");
  } catch (err) {
    console.log(err);
  }

async function removeRecursively(path) {
  try {
    //has ability to remove both file and dir
    //can delete dir recursively and forcefully
    //will delete an empty dir.
    //will remove all the contents of a dir.
    // the only difference between rmdir and rm is that rmdir can only delete dir's
    await fsp.rm(path, { recursive: true, force: true });
    console.log(path, "deleted successfully");
  } catch (err) {
    console.log(err);
  }
}

从Node.js 14.14.0开始，推荐使用fs.rmSync:

fs.rmSync(dir, { recursive: true, force: true });

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)
    }
}; 

截至节点v14(2020年10月)，fs模块有fs。rm和rs.rmSync支持递归非空目录解链接:

https://nodejs.org/docs/latest-v14.x/api/fs.html#fs_fs_rm_path_options_callback

所以你现在可以这样做:

const fs = require('fs');
fs.rm('/path/to/delete', { recursive: true }, () => console.log('done'));

or:

const fs = require('fs');
fs.rmSync('/path/to/delete', { recursive: true });
console.log('done');

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!')
  }
}

大多数在Node.js中使用fs的人都希望函数能够接近“Unix方式”来处理文件。我使用fs-extra来带来所有很酷的东西:

fs-extra包含了普通Node.js中不包含的方法 fs包。如mkdir -p、cp -r、rm -rf等。

更好的是，fs-extra是本地fs的替代品。fs中的所有方法都是未修改的，并附加到它。 这意味着你可以用fs-extra替换fs:

// this can be replaced
const fs = require('fs')

// by this
const fs = require('fs-extra')

然后你可以这样删除一个文件夹:

fs.removeSync('/tmp/myFolder'); 
//or
fs.remove('/tmp/myFolder', callback);
