What you'll learn

Real-time features like live chat and instant data updates are essential in modern web applications, but they’re difficult to build using traditional request-response APIs. In this course, FastAPI: Real-time Data Processing with WebSockets, you’ll learn to create responsive, real-time applications using FastAPI and WebSockets. First, you’ll explore how to set up a FastAPI server that supports WebSocket connections for persistent, two-way communication. Next, you’ll discover how to build a real-time chat application where messages are broadcast instantly to all users. Finally, you’ll learn how to develop a live data dashboard that streams updates from the server to the client in real time using a lightweight React or Vue frontend. When you’re finished with this course, you’ll have the skills and knowledge of real-time web development with FastAPI and WebSockets needed to build modern, interactive Python applications that respond instantly to user actions and live data.
