Quick tip
Executing code Immediately after loading a Module
Elixir has @on_load which accepts atom as function name in the same module or a tuple with function_name and its arity like {function_name, 0}.
Examples
#Hello module defmodule Hello do @on_load :onload # this executes after module gets loaded def onload do IO.puts "#{__MODULE__} is loaded successfully" end end # Execution .... Just copy and paste the code in the iex terminal # You will see the output something like this .... Elixir.Hello is loaded successfully {:module, Hello, <<70, 79, 82, 49, 0, 0, 4, 72, 66, 69, 65, 77, 65, 116, 85, 56, 0, 0, 0, 130, 0, 0, 0, 12, 12, 69, 108, 105, 120, 105, 114, 46, 72, 101, 108, 108, 111, 8, 95, 95, 105, 110, 102, 111, 95, 95, 9, ...>>, {:onload, 0}}
