Functional Web Development with Elixir, OTP, and Phoenix

Let’s Build It

We’ll begin by creating a brand-new Elixir application called islands_engine. We’ll make it a supervised application, which most Elixir applications are, because process supervision is the mechanism that provides the tremendous fault tolerance we get from the BEAM. We’ll look at supervisors in a lot more detail in Chapter 5, ​Process Supervision for Recovery​.

The command we’ll use to create our new application is mix new islands_engine --sup:

$ mix new islands_engine --sup
* creating README.md
* creating .gitignore
* creating mix.exs
* creating config
* creating config/config.exs
* creating lib
* creating lib/islands_engine.ex
* creating lib/islands_engine/application.ex
* creating test
* creating ...
