Socket.IO realtime communication training for complete beginners. Create apps, games & more (socket, websockets, chat)


The primary objective of this course is to teach beginners the fundamental Socket.IO programming skills as fast and effective as possible.

I will start teaching you the fundamental theory about sockets, then swiftly move on to practical coding.

You will learn:

  • The difference between socket IO and websockets
  • What socket events are and how to handle them
  • Know how to broadcast data
  • How to create multiple namespaces and rooms to distribute your app functionality
  • And finally, I will teach you step by step, how to code a realtime chat app from scratch.
  • Much much more…

I will take you by the hand and show you step by step, how Socket.IO programming works.

When you are done with the course, you will have acquired the necessary skills to harness real-time communication on the web & create your very own realtime applications (and not just chat apps)

Socket.IO is a JavaScript library for realtime web applications. It enables realtime, bi-directional communication between web clients and servers. It has two parts: a client-side library that runs in the browser, and a server-side library for Node.js. Both components have a nearly identical API. Like Node.js, it is event-driven.

Socket.IO primarily uses the WebSocket protocol with polling as a fallback option, while providing the same interface. Although it can be used as simply a wrapper for WebSocket, it provides many more features, including broadcasting to multiple web sockets, storing data associated with each client, and asynchronous I/O.

Socket.IO provides the ability to implement real-time analytics, binary streaming, instant messaging, and document collaboration.

Notable users include Microsoft Office, Yammer, and Zendesk.

Socket.IO handles the connection transparently. It will automatically upgrade to WebSocket if possible.
This requires the programmer to only have Socket.IO knowledge.


1: Increased worldwide demand
Socket.IO is used from startups to the big 4 software enterprises such as Microsoft. Hence, it has a great community behind it, and there’s a good possibility that your future or current employer shifts to it from realtime systems. That means that developers that know Socket.IO are in great demand and the demand is only increasing.

2: Future proof technology
The importance of Realtime Systems is not to be discounted. Instant data transmission is the norm today. Every critical system such as stock markets, emergency alerts, data analytics, traffic management, etc. need realtime data for decision making.
Socket.IO is a library made for realtime communication, providing transfer of multiple types of data-structures and binary data – image, audio and video.

3: Get your dream job
Socket.IO development skills are a requirement for a lot of tech jobs today. A simple search on any well-known job websites will reveal the requirement for the skill
