Whether you're building a chat app, live dashboard, or stock ticker, how you deliver data matters — a lot. Three popular strategies dominate the landscape: Polling Server-Sent Events (SSE) WebSockets But how do you decide which one to use? Let’s explore each, compare them, and see where they fit best! 1. Polling What is Polling? Polling is the simplest method: the client sends HTTP requests at regular intervals asking, "Any updates?" Pros: Simple to implement Works everywhere (great browser support) No persistent connection needed Cons: High server load (lots of redundant requests) Latency between updates Inefficient for truly real-time apps Use When: Data updates are infrequent Real-time experience ...

As APIs continue to be the backbone of modern web and mobile applications, developers are often faced with a key decision: GraphQL or REST ? While both serve the purpose of data exchange between client and server, they do so in fundamentally different ways. So how do you choose the right one for your project? Let’s explore both technologies, their strengths and weaknesses, and when to use what. What is REST? REST (Representational State Transfer) is an architectural style that uses HTTP methods like GET, POST, PUT, and DELETE to interact with resources. It has been the de facto standard for APIs for years. Pros of REST: Simplicity: Easy to understand and implement. Stateless: Each request contains all necessary information, enhancing scalability. Wide Adoption: Mature ecosystem, tools, and support. Caching: HTTP-level caching is straightforward. Cons of REST: Over-fetching/Under-fetching: Clients often receive too much or too little dat...

  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.
