[Library Request] python-socketio

Summary

Add the python-socketio package to the default QuantConnect Python environment.

Package details

• PyPI: https://pypi.org/project/python-socketio/
• GitHub: https://github.com/miguelgrinberg/python-socketio
• License: MIT
• Maintainer: Miguel Grinberg (active, regularly released)

python-socketio is a Socket.IO server and client implementation built on top of python-engineio. It is widely used for real-time messaging and complements the websockets package already available in the QC environment (Socket.IO adds the protocol layer — automatic reconnection, room/namespace multiplexing, fallback transports — on top of raw WebSockets).

Use case

Customer (Intercom conversation 215474452877852, Gold support plan) wants to use Socket.IO for connecting to data sources / services that expose Socket.IO endpoints rather than raw WebSocket endpoints. Quoting the customer: "an additional feature set on the already included websockets package that QC already has."

Proposed change

Add python-socketio (and its transitive dependency python-engineio) to the LEAN Python Docker image at the next batched library rebuild.

Open questions

• Pin to latest stable, or a specific version?

Start by locating the LEAN Python Docker image configuration and the existing websockets dependency or batched library rebuild process. Add python-socketio with its python-engineio dependency, resolve the version policy, and verify both packages are available in the rebuilt default Python environment.
