The content of this article is about the code implementation of file directory operations in the file system in Node.js. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

File/directory operations

(1) Determine whether the file/directory exists

fs.exists( )

## fs.access()

fs.exitesSync()

(2) Delete files/directories

                                                                                                                                           (3) Rename files/directories

##       fs.rename()

        fs.renameSync()

(4) View file/directory status

fs.stat()

fs.statSync()

                fs.stats class, details:

http://nodejs.cn/api/fs.html#fs_class_fs_stats

Example:Directory fs/fs-2.js:

// 导入模块
  const fs = require('fs');
  // 判断文件/目录 是否存在 access()
  fs.access('../fs/fs-1.js', function (err) {
     if (err) {
        console.log("文件或目录不存在!");
     } else {
        console.log("文件或目录存在!");
     }
  });
  // 重命名同上方法  删除
  // 查看文件或者目录的状态
  fs.stat('../fs/fs-1.js',function (err,stat) {
    console.log(stat.ctime);//创建时间2018-07-27T06:39:57.719Z
    console.log(stat.mtime);//修改时间2018-07-27T06:39:57.683Z
    console.log(stat.atime);//访问时间2018-07-27T06:39:57.682Z
    console.log(stat.isFile());//是否是文件 输出true
    console.log(stat.isDirectory());//是否是目录输出false
  })
