Course Overview

Elixir and OTP provide exceptional tools to build rock-solid backend applications that scale. In this course, you’ll build a web application in a radically different way, with a backend that holds application state. You’ll use persistent Phoenix Channel connections instead of HTTP’s request-response, and create the full application in distinct, decoupled layers. In Part 1, you’ll start by building the business logic as a separate application, without Phoenix. You’ll model the application domain with Elixir...Show More
