// read in the api documentation about reading files.
// read some file to the output
//
// there are many options actually.
// files coud be read with a callback. - quite efficient and simple i will use this way.
// files coud be read Sync as a return value from the function - blocking the program, this way the program wont be able serve others while waithing for the file to be read from disk.
// a stream could be created and piped to the response stream - most cpu and memory efficient.
