It has two parts: a client-side library that runs in the browser, and a server-side library for node.js. Socket.IO is event-driven and primarily uses the WebSocket protocol that allows us to emit data bi-directionally from the server and the client. Socket.IO
This video course is a complete resource, covering topics from WebSocket security to scaling the server-side of a Socket.IO application and everything in between.
This video course will provide real-world examples of how secure bi-directional, full-duplex connections that can be created using Socket.IO for different environments. It will also explain how the connection vulnerabilities can be resolved for large numbers of users and huge amounts of data/messages.
By the end of the course, you will be a competent Socket.IO developer. With the help of the examples and real-world solutions, you will learn to create fast, scalable, and dynamic real-time apps by creating efficient messaging systems between the server side and the client side using Socket.IO.
What You Will Learn
Build rich and interactive real-time dashboards using Socket.IO to pipe in data as it becomes available
Design chat and multiple-person interfaces that leverage Socket.IO for communication
Segment conversations to rooms and namespaces so that every socket doesn’t have to receive every message
Secure your data by implementing various authentication techniques, locking down the HTTP referrer and using secure WebSockets
Load balance across multiple server-side nodes and keep your WebSockets in sync using Redis, RabbitMQ or Memcached
Stream binary data such as audio and video in real-time over a Socket.IO connection
Create real-time experiences outside of the browser by integrating Socket.IO with hybrid mobile applications
