What is WebSocket Flask?
Flask-SocketIO is a Flask extension that relies upon eventlet or gevent to create server-side WebSockets connections. websocket-client provides low level APIs for WebSockets and works with both Python 2 and 3.
What is the difference between WebSocket and socket IO?
Key Differences between WebSocket and socket.io It provides the Connection over TCP, while Socket.io is a library to abstract the WebSocket connections.

listen(port); // Create a Socket.IO instance, passing it our server var socket = io. listen(server); // Add a connect listener socket. on(‘connection’, function(client){ console. log(‘Connection to client established’); // Success!
Is Socket.IO compatible with WebSocket?
Although Socket.IO indeed uses WebSocket for transport when possible, it adds additional metadata to each packet. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a plain WebSocket server either.

Add below code into requirments.txt.
What is the flask-socketio extension?
The Flask-SocketIO extension (shameless plug as I’m the author) is a wrapper for gevent and gevent-socketio on the server, plus Socket.IO on the client. Socket.IO is higher level socket protocol that can use web socket if available but can also use other transport mechanisms on older browsers.
