FastAPI WebSockets

FastAPI WebSockets enable bi-directional, real-time communication between clients and servers with native async support and minimal boilerplate.

FastAPI WebSockets leverage Starlette and Python's async/await syntax to handle persistent, full-duplex connections out of the box. By defining endpoints with the @app.websocket decorator, developers can easily manage incoming and outgoing data streams (supporting text, binary, and JSON payloads) while utilizing FastAPI's dependency injection system for tasks like authentication. This native integration eliminates the need for complex external wrappers, making it a highly efficient choice for building low-latency features like live chat applications, real-time dashboards, and collaborative tools.
