There are many ways out of these we prefer to go with “ socket.io.” It is a library that allows us to do real-time, bidirectional, and event-based communication between the browser and the server, which is based on Node.js and a Javascript client library for the browser. WebSocket helps to create real-time communication between web servers and clients. The server and client can communicate and acknowledge or exchange the data at the same time. It allows the server and client to communicate in an asynchronous way. The server can send messages to the client, and the client sends its response back with the same connection, which is created initially. The WebSocket connection is a persistent connection between a client app and the server. To avoid this, we can go with WebSockets. For real-time data, it is too much processing. That means, when you have to do communication, it always opens the connection, does its processing, and returns with some response by closing the connection. The major con of HTTPS for real-time data transfer is that HTTPS is unidirectional. After the initial handshake occurs over HTTP, there is no more notion of HTTP related things, for example, cookies.
The WebSockets protocol is completely different from the HTTP or HTTPS protocol. But if you want real-time & quick data transfer, HTTPS is not recommended. The most used communication protocol is the HTTPS protocol. There are many types of protocols we can follow for communication between two or more systems.
