This article mainly introduces the detailed explanation of nodejs rendering page resources through response writeback. Now I share it with you and give it as a reference.

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(&#39;http&#39;);
var fs = require(&#39;fs&#39;);
var server = http.createServer();
server.on(&#39;listening&#39;,()=> {
  console.log(&#39;server starts at localhost 8080&#39;);
})
server.listen(&#39;8080&#39;,&#39;localhost&#39;);

//监听服务
server.on(&#39;request&#39;,(req,res)=>{
  if(req.url == &#39;/&#39;) {//渲染html文件
    fs.readFile(&#39;./html/node.html&#39;,(err,info)=>{
       res.write(info);
       res.end();
    })
  } else if(req.url.startsWith(&#39;/static&#39;)) {//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();
    })
  }
})

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
