It wraps the python-socketio package and integrates it into Flask's request/response model, letting you define event handlers as decorators and emit messages bidirectionally. The package depends on flask, python-socketio, werkzeug, jinja2, click, and blinker\u2014all standard Flask ecosystem components.\n\nTypical use is defining server-side event handlers with @socketio.event decorators, then running the app with socketio.run() instead of app.run(). Clients connect via a JavaScript Socket.IO client library and exchange JSON-serializable messages. This pattern is common for live dashboards, collaborative tools, notifications, and any application where the server needs to push updates to connected clients without polling.","worth_installing":"Yes. Flask-SocketIO is actively maintained, has low install friction, carries a permissive MIT license, and solves a real problem\u2014adding WebSocket support to Flask with minimal boilerplate. It's in the top 5000 packages by downloads and has no known vulnerabilities. Install it if you need real-time bidirectional communication in a Flask app."},"id":"flask-socketio","links":{"html":"https://skillfed.io/packages/flask-socketio","md":"https://skillfed.io/packages/flask-socketio.md","pypi":"https://pypi.org/project/flask-socketio/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-02-21","license_spdx":null,"license_treatment":"permissive","name":"Flask-SocketIO","python_support":"supports_current","summary":"Socket.IO integration for Flask applications"},"popularity":{"monthly_downloads":5242836,"position":2130,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"5.6.1"}
