Question

I am writing HTTP server on top of Node.js, without using HTTP module.

Retrieving a GET message: GET /www/index.html HTTP/1.1 should send a response with the file located at /www/index.html, same with images and other files.

Could anyone guide me to a javascript way to fetch the files from disk and add them to my HTTP response ?

My server should be able to support the following content types :

1. JavaScript: application/javascript
2. HTML: text/html
3. CSS: text/css
4. JPEG: image/jpeg
5. GIF: image/gif

I think the fs module is what you are looking for.

It provides various function to open and read from files. A simple example :

fs.readFile('/etc/passwd', function (err, data) {
  if (err) throw err;
  console.log(data);
});
