Pokemon API

We can request information about Pokemon using the Pokemon API.

When we rely on an external API, it’s possible for them to change the format of a response, and have that cause issues for our application.

That’s why it’s often important to translate information from an API into a struct when we retrieve it. This way if the format of the API response changes then we can fix the issue in a single spot where we convert the API response into a struct. We can also keep only the information we want, rather than all of the data returned.

{:ok, response} = HTTPoison.get("https://pokeapi.co/api/v2/pokemon/charmander")

In the Pokemon.from_response/1 function, Decode the above response into an Elixir map using the Poison library. then use the converted response to create a Pokemon struct with :name, :weight, and :height fields.

Pokemon.from_response(response)
%Pokemon{name: "charmander", weight: 85, height: 6}

Enter your solution below.

defmodule Pokemon do
  defstruct [:name, :weight, :height]

  def from_response(response) do
    nil
  end
end

Pokemon.from_response(response)

Types (Bonus)

Add :types to the Pokemon struct and use the "types" field from response to create a list of types.

Pokemon.from_response(response)
%Pokemon{name: "charmander", weight: 85, height: 6, types: ["fire"]}
