使用Node操作文件夹的常用API

const fs = require("fs");
fs.mkdir("./code",(err,file)=>{
  if(err){
    console.log("文件夹创建失败");
  }else{
    console.log(file);
  }
})

const fs = require("fs");
fs.mkdirSync("./aaa");

const fs = require("fs");
fs.readdir("./code",(err,fileList)=>{
    if(err){
        console.log("文件夹读取失败");
    }else{
        console.log(fileList);
    }
})

const fs = require("fs");
fs.readdir("./code",{withFileTypes:true},(err,fileList)=>{
    if(err){
        console.log("文件夹读取失败");
    }else{
        console.log(fileList);
    }
})

const fs = require("fs");
fs.rename("./aaa","./why",(err,flag)=>{
    if(err){
        console.log("文件重命名失败");
    }else{
        console.log("文件重命名成功");
    }
})

const fs = require("fs");

function readDictionary(dir){
    fs.readdir(dir,{withFileTypes:true},(err,fileList)=>{
        fileList.forEach(item=>{
            if(item.isDirectory()){
                readDictionary(`${dir}/${item.name}`)
            }else{
                console.log(item.name);
            }
        })
    })
}
readDictionary('./code')
