Viewed 5k times 3. I have set up a socket server There are multiple Python web frameworks capable of doing that, but for this demostration we will use FastAPI, a modern async framework that is gaining momentum in the new space of Python async frameworks. Streaming in WebSockets basically means sending small data packets over an open connection between the server and the client.

A WebSocket-Server framework. it contains threading and asyncio modules. you can use threading module by Pyws, if you can program asynchronously, you can also use asyncio module by AsyncPyws. if server want to send msg to client by polling, you can use radio middleware. pip install: Abstracts WebSocket communications to automatically fall back to flash streaming or long-polling when necessary (on either server or client) Adds features like heartbeats, timeouts, and disconnection support not provided in WebSocket API It is merely :adequate for WebSocket handshake messages. These APIs cannot be imported from websockets.

websockets is a library for building WebSocket servers and clients in Python with a focus on correctness and simplicity. Built on top of asyncio, Python’s standard asynchronous I/O framework, it provides an elegant coroutine-based API. Here’s how a client sends and receives messages:
