flask-socketio

Works as a Flask extension with decorators, allowing developers to add real-time features using familiar Flask patterns without a steep learning curve.

Uses decorators for Socket.IO events similar to Flask routes, making it intuitive to handle client-server interactions for real-time updates.

Provides built-in room management and broadcast support, enabling targeted communication to groups or all clients without custom implementation.

Leverages Socket.IO for automatic fallbacks to polling, ensuring connectivity in restrictive network environments like those with proxies or firewalls.
