# NP Basics

# Directory structure

NP is a traditional multi-entry application, where each file in the public directory is an entry. The original version does not use namespaces and is basically function-oriented programming.

The big function module can be divided into two pieces: Web side and Tracker side (the following files are located in the include directory).

  • Web side: main entry bittorrent.php, function file functions.php
  • Tracker side: main entry bittorrent_announce.php, functions file functions_announce.php
  • Common parts of both: common functions files globalfunctions.php, core.php

To add a new function, just: create a new entry file -> introduce the main entry -> start the specific business logic.
