Simple Chat Application

This repository contains the source code for a simple chat application implemented in both Python and C++. It includes a WebSocket server written in each language and a single web-based client that can connect to either server.

Prerequisites

For Python Server

• Python 3.x
• websockets library

For C++ Server

• C++11 compiler (e.g., g++)
• Boost Libraries
• WebSocket++ library
• nlohmann/json library

Installation

Python Server

1. Install Python 3.x (if not installed): Python Installation Guide
2. Install Dependencies:

   pip install websockets

C++ Server

1. Install C++ Build Tools: Ensure g++ and CMake are installed.
2. Install Boost Libraries:

   sudo apt-get install libboost-all-dev

3. Install WebSocket++:

   git clone https://github.com/zaphoyd/websocketpp.git

4. Install nlohmann/json:

   sudo apt-get install nlohmann-json3-dev

Building and Running the Servers

Python Server

To run the Python server, navigate to the python directory and execute the following command:

python server.py

This will start the WebSocket server on localhost:8765.

C++ Server

To build and run the C++ server, navigate to the cpp directory and execute the following commands:

1. Compile the Server:

   g++ -std=c++11 chat_server.cpp -o chat_server -I ./websocketpp -I ./include -lboost_system -lpthread

2. Run the Server:

   ./chat_server

This will compile and start the WebSocket server on localhost:8765.

Using the Client

Open the client/index.html file in any modern web browser to connect to the running WebSocket server. Ensure that either the Python or C++ server is running before opening the client.

1. Enter a username in the provided input field.
2. Type a message and click Send to broadcast it to all connected clients.
3. Received messages from other clients will be displayed in real time.

Notes

• The C++ server requires proper setup of WebSocket++ and Boost, including ensuring that paths in the compilation command are correct.
• Both servers listen on the same port (8765), so ensure that only one server is running at a time when using the client.
