What is most correct way to open, read and parse JSON file with poison?

For example if we have example.json file in root of some project.

Is it?

def get_json(filename) do
    # ....
end

P.S Sorry for question i’m :eggplant: in Elixir

I’m not sure if it’s the correct way, but I would do something like this

defmodule Test do
  def get_json(filename) do
    with {:ok, body} <- File.read(filename),
         {:ok, json} <- Poison.decode(body), do: {:ok, json}
  end
end
