WebSocket

• WebSocket is a computer communications protocol.
• WebSocket is designed to work over HTTP ports 80 and 443 as well as to support HTTP proxies and intermediaries.
• More like a handshake between the client and the server.

Socket.IO Tutorial

• Socket.IO enables real-time bidirectional event-based communication
• Built on top of the WebSockets API (Client side) and Node.js
• It has two parts: a client-side library that runs in the browser, and a server-side library for node.js
• Real-Time Application (RTA) is an application that functions within a period that the user senses as immediate or current like instant messages or online gaming.
• Very popular to use.
• Broadcasting means sending a message to all connected clients.
• Socket.IO allows you to “namespace” your sockets, which essentially means assigning different endpoints or paths
• Within each namespace, you can also define arbitrary channels that sockets can join and leave, also known as 'rooms'.
• A way to handle errors (https://www.tutorialspoint.com/socket.io/socket.io_error_handling.htm)
• Has a way to debug
