同步删除文件夹

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

    const deleteFolderRecursive = function (directoryPath) {
    if (fs.existsSync(directoryPath)) {
        fs.readdirSync(directoryPath).forEach((file, index) => {
          const curPath = path.join(directoryPath, file);
          if (fs.lstatSync(curPath).isDirectory()) {
           // recurse
            deleteFolderRecursive(curPath);
          } else {
            // delete file
            fs.unlinkSync(curPath);
          }
        });
        fs.rmdirSync(directoryPath);
      }
    };

我希望有一种方法可以做到这一点，而不需要为如此微小和常见的东西添加额外的模块，但这是我能想到的最好的方法。

更新: 现在应该在Windows上工作(测试Windows 10)，也应该在Linux/Unix/BSD/Mac系统上工作。

const
    execSync = require("child_process").execSync,
    fs = require("fs"),
    os = require("os");

let removeDirCmd, theDir;

removeDirCmd = os.platform() === 'win32' ? "rmdir /s /q " : "rm -rf ";

theDir = __dirname + "/../web-ui/css/";

// WARNING: Do not specify a single file as the windows rmdir command will error.
if (fs.existsSync(theDir)) {
    console.log(' removing the ' + theDir + ' directory.');
    execSync(removeDirCmd + '"' + theDir + '"', function (err) {
        console.log(err);
    });
}

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!`);
  });
});

2020年更新

从12.10.0版本开始，为选项添加了recursiveOption。

注意，递归删除是实验性的。

所以你会做同步:

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

或者async:

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

//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);
