I am pretty new to Node.js and I went through a tutorial and set up my own server who responses to some requests with basic html.

```
var body = '<html>'+
            '<head>'+
            '<meta http-equiv="Content-Type" content="text/html; '+
            'charset=UTF-8">'+

            '</head>'+
            '<body>'+
            '<form action="/upload" method="post">'+
            '<textarea name="text" rows="20" cols="60"></textarea>'+
            '<input type="submit" value="Submit text">'+
            '</form>'+
            '</body>'+
            '</html>';

response.writeHead(200, {"Content-Type": "text/html"}); 
response.write(body); 

```

I have from a former project (basic html and JS) a javascript function which basically draws a table (calendar).

But how would I use it in Node.js? I dont really understand how I should build up the website?
