Here I have used the express framework to make easier.

The html form "index.html"

<html>
  <head><title>Login</title></head>
  <body>
    <form action="myaction">
      <input type="text" name="mytext"/>
      <input type="password" name="mypass"/>
      <input type="submit" value="submit"/>
    </form>
  </body>
</html>

and on the server side on "app.js"

var express = require('express');
var fs = require('fs')
var app = express.createServer();

app.get("/", function(req, res) {
  fs.readFile("index.html", function (err, data) {
    if (err) {
      res.contentType("html");
      res.send("File not found");
      }
    else{ 
      res.contentType("html");
      res.send(data);
    }
  });      
});

app.get("/myaction", function(req, res) {
  if(req.param("mytext") === "admin" && req.param("mypass") === "admin"){
    res.contentType("html");
    res.send("You are authenticated");
  }
  else{
    res.contentType("html");
    res.send("Invalid Username or password");
  }
});

app.listen(8000);
console.log("Server running on localhost:8000");
