FastAPI Websocket Pub/Sub
A fast and durable Pub/Sub channel over Websockets for realtime data propagation in FastAPI applications.
What is FastAPI Websocket Pub/Sub?
FastAPI Websocket Pub/Sub is a Python library that implements a scalable publish/subscribe pattern over WebSockets, enabling real-time multi-cast communication across the web and cloud. It combines FastAPI's ASGI platform with a robust bidirectional channel to facilitate live data updates, remote control, and distributed computing. The library emphasizes durability, real-time performance, and integration with modern Python async ecosystems.
Python developers building real-time web applications that require bi-directional communication, such as live updates, remote control systems, or distributed computing solutions. It is particularly suited for those already using or familiar with FastAPI who need scalable Pub/Sub functionality.
Developers choose this library because it seamlessly integrates with FastAPI, leveraging its dependency injection for authentication and other logic, while providing structured data serialization with Pydantic models. Its unique selling point is the combination of WebSockets with a durable Pub/Sub pattern, supporting cross-server syncing via backends like Redis or PostgreSQL for scalable multi-instance deployments.
