6. 모듈을 통한 간단한 웹 서버 만들기

var http = require('http');
var fs = require('fs');
var app = http.createServer(function(request,response){
    var url = request.url;
    if(request.url == '/'){
      url = '/index.html';
    }
    else if(request.url == '/favicon.ico'){
      return response.writeHead(404);
    } else {
      response.writeHead(404);
      response.end('Not found');
    }
    response.writeHead(200);
    // console.log(__dirname + url);
    response.end(fs.readFileSync(__dirname + url));
    // response.end('helloworld!!' + url);
 
});
app.listen(3000);

<h1>hello world!</h1>
