ProNet

<<<<<<< HEAD
ProNet is a minimal yet professional client-server application built in modern C++ using Winsock and CMake. It enables structured peer-to-peer message exchange using JSON (via json.hpp) without relying on third-party libraries like Boost. It's designed to showcase clean architecture, real-time communication, and professional code organization in a native Windows environment.

Professional Networking App (Client-Server Model)

A lightweight C++ client-server networking application built using the Winsock API on Windows. This project demonstrates the networking fundamentals, socket programming, and clean software design principles. The app simulates a basic professional networking platform where users can connect and exchange messages.

Purpose

This project is designed to showcase:

  • Understanding of TCP socket communication using Winsock.
  • Clean separation of concerns between client and server logic.
  • Well-structured code with modern C++ practices.
  • Readable, documented code with proper error handling.

It can be extended to support multiple clients, user registration, or even integrate a database in the future.

Features

TCP connection between a client and server
Modular code with .cpp and .h separation
Basic message exchange functionality
Winsock initialization and teardown
Easily extensible architecture

Technologies Used

  • C++17
  • Winsock2 API
  • CMake
  • Ninja or MinGW Make
  • Windows (MINGW64 / MSYS2)
