Working with socket.io

WebSockets is a technology that provides real-time communication between a client and a server via a TCP connection, eliminating the need for customers to continuously check whether API endpoints have updates or new content. Clients create a single connection to a WebSocket server, and wait to listen to new server events or messages.

The main advantage of WebSockets is that they are more efficient because they reduce the network load and send information in the form of messages to a large number of clients.

Among the main features of WebSockets, we can highlight the following:

They provide bidirectional (full duplex) communication over a single TCP connection.
They provide real-time communication between a server and its connecting clients. This enables the emergence of new applications oriented toward managing events asynchronously.
They provide concurrency and improve performance, optimizing response times and resulting in more reliable...
