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 functions and simple data structures.

In Part 2, you’ll add in the GenServer Behaviour to make managing in-memory state a breeze. 

In Part 3, you’ll build a web interface with Phoenix where you’ll use Phoenix Channels to establish persistent connections between the stateful server and a stateful front-end client.

Needless to say, you’re going to love this way of building web apps!

Functional Web Development with Elixir, OTP and Phoenix

## The building blocks of the game
We’ve made good progress so far. We modeled the most important building blocks of the game. We can see how coordinates compose into islands and boards.

Our domain is simpler because of the approach we’ve taken. Our domain entities live single lives in our application instead of double lives in both the application and the database. Application behavior comes from simple functions that transform data. There’s not an #key# ORM: Object-relational mapping #key# in sight.

While we are in a good position, the code we currently have allows any action to happen at any time.
