In this section, we review how we can use the socket.io module to create a webserver based in Python.
Python Socket.io
Introducing WebSockets
WebSockets is a technology that offers realtime communication between a client and server through a TCP connection, and eliminates the need for customers to be continually checking whether API endpoints have updates or new content. Clients create a single connection to a WebSocket server and remain pending to listen for new events or messages from the server.
The main advantage of websockets is that they are more efficient as they reduce the network load and send information to a large number of clients in the form of messages.
