Introduction:
WebSocket is a powerful communication protocol that enables real-time, full-duplex communication between a client and a server over a single, long-lived connection. In this article, we'll explore how to build a simple chat application using WebSocket in Python.

 

1. Setting up the Server:

 

import asyncio
import websockets

async def chat_server(websocket, path):
    async for message in websocket:
        # Broadcast the received message to all connected clients
        await asyncio.gather(*[ws.send(message) for ws in connected])
        
async def main():
    server = await websockets.serve(chat_server, "localhost", 8765)
    await server.wait_closed()

connected = set()
asyncio.run(main())

 

2. Setting up the Client:

 

import asyncio
import websockets

async def chat_client():
    async with websockets.connect("ws://localhost:8765") as websocket:
        while True:
            message = input("Enter message: ")
            await websocket.send(message)

asyncio.run(chat_client())

 

3. Running the Application:

• Start the server by running the server code.
• Run the client code in multiple terminals to simulate multiple users.
• Users can now send messages, and the server will broadcast them to all connected clients.

 

Conclusion: 

In this article, we've demonstrated how to implement a simple chat application using WebSocket in Python. WebSocket's real-time capabilities make it ideal for building interactive applications such as chat platforms, multiplayer games, and collaborative tools.
