In this course, you will learn how to build real-time applications that will be fast with less resource overhead. Today’s software users expect the data on their screens to reflect instantly. You will win your users’ trust by giving them a seamless application experience powered by real-time features.

This course is broken up into three parts. In Part 1, you will focus on the essential part of the real-time stack (Elixir, – Phoenix channels, websockets, and GenStage). This will set the foundation for building real-time applications.

In Part 2, you will add features to an e-commerce application that serves many users simultaneously. You will also get to work with some of the more advanced features of Phoenix, such as Phoenix Tracker.

In Part 3, you will finish the course with guidance on running real-time applications in production. The battle is only beginning when you write an application. You have to then keep it healthy and happy in production.
