// Require http module

// Require fs module
var fs = require('node:fs');

// Require minimist module (make sure you install this one via npm).
var mini = require('minimist');

// Use minimist to process one argument `--port=` on the command line after `node server.js`.
var arg = mini(process.argv.slice(2));

// Define a const `port` using the argument from the command line.

// Use the fs module to create an arrow function using `fs.readFile`.
// Use the documentation for the Node.js `fs` module. 
// The function must read a file located at `./public/index.html` and do some stuff with it.
// The stuff that should be inside this function is all below.
// If there is an error, put it on the console error and return. 
// Do not be nice about exiting.
fs.readFile('./public/index.html','utf8', (error, info) => {

// The function should have three responses: 
// 1. status code 200, 
res.statusCode=200;
// 2. set a header with content type `text/html`, and   
res.setHeader('Content-Type', 'text/html');
// 3. end with the data that you are reading in from ./public/index.html.  
res.end(info);
});
  
// Start the `server` const listening on the port defined by argument in your `port` const. 
// Put the exact message `Server listening on port ${port}` on the console log. 
server.listen(port);
console.log(`Server listening on port ${port}`); 
});  
// That's it! You're all done!
