  • 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

Will learning Socket.IO make me more employable or likely to get promoted?
Learning more and having additional knowledge than your peers is always beneficial. Even if your current job role doesn’t require real-time communication, it gives you insight on how to approach problems differently, what is the better way to solve it. Maybe you or your organization is using Rest APIs for some application which is better realtime and Sockets IO can be of help there. Coming up with more solutions make you more valuable for everyone.
How is Socket.IO helpful in Game Development?
In online multiplayer games, the stats of players need to be shared with each other. Usually, a clone of one player is made in another player’s environment. Whatever stats and actions the actual player perform, the clone copies. Socket.IO can be used to send information from real to clone and back from clone to real. For e.g. the clone gets hit by a bullet, an event will get fired which deducts the main player’s health.
