Elixir & Phoenix: Scalable Backend Development · Lesson

Documentation and Static Analysis with Dialyzer

Write self-documenting Elixir with doc attributes, typespecs, and doctests, then catch type errors before runtime using Dialyzer and Credo.

Code That Explains Itself

Maintainable Elixir is well documented and statically checked. Elixir bakes documentation and type hints right into the language, and tools verify them automatically.

Module Documentation

Use @moduledoc for a module overview and @doc for each public function. These power generated docs and editor tooltips.

defmodule Calculator do
  @moduledoc "Simple arithmetic helpers."
  @doc "Adds two numbers."
  def add(a, b), do: a + b
end
