This course introduces developers to the Socket.io library, a free Node.js module for simplifying real-time functionality. Using Socket.io, developers are able to configure sockets for sending and receiving messages using the browser. In this course, Building Real-time Applications with Socket.io, you'll learn to build modern, real-time applications using the power of Socket.io. You'll start with an introduction to Socket.io and some of the demo apps that will be used in the course. Next, you'll discover some of the basics of what Socket.io is and how it's used within the Node.js framework. Finally, you'll build a chat application which will be able to send messages to all users, emit private messages, and you'll see how to set up private rooms. By the end of this course, you'll be prepared to tackle projects that can then deliver streaming data using simple event-driven methods.
