Scratcher is a library for calling various HTTP Clients equivalently. The behavior of a simple HTTP Client in Elixir

It respects the design of the ex_aws HTTP client module. ExAws.Request.HttpClient

You can call various HTTP Clients within your module by following the steps below.

1. Use a module that already implements Scratcher.HttpClient as Behavior, or implement a module that uses the HTTP Client that you want to use.
2. Specify the module in Config.
3. The module that wants to send HTTP request can use the HTTP Client module obtained from Config.

  defmodule Your.HttpClient do
    @behaviour Scratcher.HttpClient
    def request(method, url, body, headers, http_opts) do

      # use hackney, httpoison, httpotion...

      {:ok, %{status_code: 200, body: "..."}}
    end
  end

config :your_module, http_client: Your.HttpClient

  defmodule YourModule do
    @http_client Application.fetch_env!(:your_module) |> Keyword.fetch!(:http_client)

    def request(method, url, body, headers, http_opts) do
      @http_client.request(method, url, body, headers, http_opts)
    end
  end

If available in Hex, the package can be installed by adding scratcher to your list of dependencies in mix.exs:

def deps do
  [
    {:scratcher, "~> 0.1"}
  ]
end
