server.js

const http = require('http');
const hostname = '127.0.0.1';
const port = 3000;

var server = http.createServer();
server.on('request', doRequest);
var fs = require('fs');

function doRequest(req, res) {
  var url = req.url;

  if (url.match(/html/)) { // favicon対策
    fs.readFile('.' + url, 'utf-8', doReard);
  }

  function doReard(err, data) {
    res.writeHead(200, {'Content-Type' : 'text/html'});
    res.write(data);
    res.end();
  }
}

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});
