This time I will bring you a detailed explanation of the steps for nodejs to render a page through response writeback. What are the precautions for nodejs to render a page through response writeback. Here is a practical case, let's take a look.

We generally operate page rendering through the api provided by the node framework. How to use the original write-back method to achieve the same function?

The following is asynchronously reading a file through the node provided All content api readFile operates, the code is as follows:

html

 <!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <link rel="stylesheet" type="text/css" href="./static/style.css" rel="external nofollow" />
  <title>Document</title>
</head>
<body>
  <p>这是一个p </p>
  <p>这是一个p </p>
  <p>这是一个p </p>
  <p>这是一个p </p>
  <p>这是一个p </p>
  <p>这是一个p </p>
  <p>这是一个p </p>
  <p>这是一个p </p>
  <p>这是一个p </p>
  <p>这是一个p </p>
  <p>这是一个p </p>
  <script type="text/javascript" src="./static/test.js"></script>
 </body>
</html>

/static folder contains test.js and style.css files

 p:nth-child(1){
  font-size: 50px;
  color: red;
}
p:nth-child(3){
  font-size: 80px;
  color: blue;
}
p:nth-child(6){
  font-size: 100px;
  color: blueviolet;
}

app.js

 // 搭建服务
var http = require('http');
var fs = require('fs');
var server = http.createServer();
server.on('listening',()=> {
  console.log('server starts at localhost 8080');
})
server.listen('8080','localhost');
//监听服务
server.on('request',(req,res)=>{
  if(req.url == '/') {//渲染html文件
    fs.readFile('./html/node.html',(err,info)=>{
       res.write(info);
       res.end();
    })
  } else if(req.url.startsWith('/static')) {//统一渲染html需要的static静态文件到页面
    fs.readFile(dirname + req.url,(err,info) =>{
      res.write(info);
      res.end();
    })
  }
})
