避免手动重新加载页面？

Question

在登录控制台了解文件更改之前一切正常。是否可以在不手动重新加载页面的情况下将文本文件的内容更新到浏览器中？

var http = require('http');
var url = require('url');
var fs = require('fs');
http.createServer(function (req, res) {
    var q = url.parse(req.url, true);
    if(q.pathname == "/") {
    return res.end("Please request any file");      
    }
  if ( q.pathname == "/target.txt") {
    var filename = "C:\\Users\\Hp\\Documents\\Development" + q.pathname;    
  }
  else if(q.pathname == "/target1.txt") {
    var filename = "C:\\Users\\Hp\\Documents\\Development\\Node Programs\\file system module" + q.pathname;
  }
  else {
    return res.end("No such file found!");
  }
    fs.readFile(filename, function(err,data) {
    if(err) {
    return res.end("404 Not Found");
    } 
    res.writeHead(200,{'Content-Type': 'text/html'});
    res.write(data);
    res.write("Now watching "+ filename);
    console.log("Now watching file");
  });

  fs.watch(filename, () => {
    fs.readFile(filename, function(err,data) {
    res.writeHead(200,{'Content-Type': 'text/html'});
    res.write(data);
    res.write("Now watching "+ filename);    
    console.log("File changed");
    res.write(q.pathname+": File changed!");
    res.end();
  });
  });
  }).listen(8080);
