Why doesn't the cutter appear?

Question

Node.js

In general, I test templates. And for this I wrote a server on IO.js. I struggled with MIME types for a long time, but when I saw that everything was correct, I realized that it was not about them.
The most surprising thing is that if I open not through a local server, then everything is ok.
The code

var http = require('http'),
    fs = require('fs'),
    typer = require('./typer.js');

http.createServer(function (request, response) {
  console.log(request.url);
  if(request.url == '/'){
    request.url = 'chablone1.html';
  } else {
    request.url = '.' + request.url;
  }
  var options = {
    'Content-Type': typer.type(request.url)
  }
  response.writeHead(200, options);
  function data(chunk){
    response.write(chunk.toString());
  }
  function end(){
    response.end();
  }
  var file = fs.createReadStream(request.url);
  file.on('data', data);
  file.on('end', end);
}).listen(80);
