defmodule KayaanPrints.EnvLoader do
  def load_env(path \\ ".env") do
    if File.exists?(path) do
      File.stream!(path)
      |> Stream.map(&String.trim/1)
      |> Enum.each(fn line ->
        [key, value] = String.split(line, "=")
        System.put_env(key, value)
      end)
    end
  end
end

So, I’m using the above module to load env variables into System. And in my config file, I have added the below code:

if config_env() in [:dev, :test] do
  Code.eval_file("lib/kayaan_prints/env_loader.ex")
  KayaanPrints.EnvLoader.load_env()
end

It doesn’t throw any error but it shows this as a problem:
redefining module KayaanPrints.EnvLoader (current version defined in memory)

I think it is due to Code.eval_file which loads and evaluates the file everytime it recompiles. Importing module doesn’t work as well. How do i resolve this? if I don’t want to write the whole module code in config.exs file, is there any way i can somehow import it into config?
