How does NodeJs write newline data to local files?

Regarding how nodejs writes newlines of data one by one, you can use \r\n, but the operating system is different, and there will be conflicts. To avoid this problem, I found a surefire way, which is to use the os module that comes with node ( os .EOL ):

1. Import module


//引入模块
const fs = require('fs')
const os = require('os')

Two, the core part

//创建一个数组
const list = [
  1,2,3,4,5,6,7,8,9,10
]


//将数组中每个数据写入并换行
for(let i = 0; i<list.length;i++){
  let item = list[i] + os.EOL   //使用os.EOL工具换行
  
  //使用appendFile()将数据累计写入
  fs.appendFile('./text.js',item,function(err){
    if(err){
      console.log('写入失败！')
    } else {
      console.log('success')
    }
  })
}

3. Final result

The above is the valuable information in this article, I hope it will be helpful to you!
