  In today’s hyper-connected world, users expect real-time interactions—whether it's chatting with support, receiving stock updates, or tracking delivery in motion. Traditional HTTP was never built for this level of immediacy. Enter WebSockets —the game-changer for real-time, two-way communication between clients and servers. What are WebSockets? WebSockets are a protocol that enables persistent, full-duplex communication between the client and the server over a single TCP connection. Unlike HTTP, which is request-response based, WebSockets allow data to flow freely both ways without repeatedly opening new connections. How WebSockets Work Handshake : It starts with an HTTP request to initiate the WebSocket connection. Upgrade : If the server accepts, the protocol switches from HTTP to WebSocket. Persistent Connection : Once established, both the client and server can send data at any time. WebSockets vs. HTTP Polling Use Cases of WebSockets...

  In recent years, Python has continued to dominate the world of web development due to its simplicity, readability, and vibrant ecosystem. While frameworks like Django and Flask have long held the spotlight, a newer contender—FastAPI—is taking the developer community by storm. Built for high-performance APIs with modern Python features, FastAPI is redefining how backend development is done. But what makes it so special? And why is it widely considered the future of Python web development ? Let’s dive in. What is FastAPI? FastAPI is a modern, high-performance web framework for building APIs with Python 3.7+ based on standard Python type hints. Created by Sebastián Ramírez , it leverages Starlette for the web layer and Pydantic for data validation. From its intuitive syntax to blazing-fast response times, FastAPI is designed for speed, developer happiness, and production-ready scalability. Key Features of FastAPI 1.
