Node.js功能模块

简介如下：

fs.promises => 异步操作文件

fs.stat => 判断是文件还是文件夹

fs.unlink => 删除文件

fs.readdir => 读取文件夹内容

详情请查询Nodejs官网：/api/fs.html

代码如下：

/*** @caption 删除本地文件夹/文件* @param {String} directoryPath 例： d://x/x/x.json 或者 d://x/x/x* *@param {Function} callback 例：回调*/export let _deleteDir = (directoryPath, callback) => {const fs = require('fs').promises;async function rmdirAsync (directoryPath) {try {let stat = await fs.stat(directoryPath)if (stat.isFile()) {await fs.unlink(directoryPath)} else {let dirs = await fs.readdir(directoryPath)// 递归删除文件夹内容(文件/文件夹)dirs = dirs.map(dir => rmdirAsync(path.join(directoryPath, dir)))await Promise.all(dirs)await fs.rmdir(directoryPath)}} catch (e) {alert(e);console.error(e);}}require('fs').existsSync(directoryPath) && rmdirAsync(directoryPath).then(() => {// 确保文件/文件夹均已删除 => 回调callback && callback();})}
