//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 fs = require("fs");
fs.rmdir("./test", { recursive: true }, (err) => {
  if (err) {
    console.error(err);
  }
});

提供递归:true选项。并且它将递归地删除给定路径下的所有文件和目录。(假设test是根目录)

另一种替代方法是使用fs-promise模块，该模块提供fs-extra模块的承诺版本

你可以这样写:

const { remove, mkdirp, writeFile, readFile } = require('fs-promise')
const { join, dirname } = require('path')

async function createAndRemove() {
  const content = 'Hello World!'
  const root = join(__dirname, 'foo')
  const file = join(root, 'bar', 'baz', 'hello.txt')

  await mkdirp(dirname(file))
  await writeFile(file, content)
  console.log(await readFile(file, 'utf-8'))
  await remove(join(__dirname, 'foo'))
}

createAndRemove().catch(console.error)

注意:async/await需要最新的nodejs版本(7.6+)

❄️您可以使用graph-fs

directory.delete()

如果你更喜欢async/await，你可以使用fs/promises API。

const fs = require('fs/promises');

const removeDir = async (dirPath) => {
  await fs.rm(dirPath, {recursive: true});
}

如果您知道文件夹中单个文件的路径，并希望删除包含该文件的文件夹。

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

const removeDir = async (filePath) => {
  const { dir } = path.parse(filePath);
  await fs.rm(dir, { recursive: true });
}

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);
      }
    };
