Deepl

Batteries-included Elixir library for dealing with Deepl API. With batteries I mean caching.

Installation

def deps do
  [
    {:deepl, github: "kim-company/deepl"}
  ]
end

Usage

You can create a Deepl client by calling the Deepl.new() function providing the necessary options, which usually depend on the environment. For testing, you might want to use Req.Test capabilities and mock the responses, here is an example

# Somewhere in the code you pass these options to the initializatin function
Deepl.new(plug: {Req.Test, Deepl})

# In the test then you can create the appropriate stubs
Req.Test.stub(Deepl, fn conn ->
  case conn.path_info do
    ["v2", "languages"] ->
      Req.Test.json(conn, [
        %{
          language: "DE",
          name: "German",
          supports_formality: true
        }
      ])
  end
end)

Refer to Req's guide for more.

In production, you'll want to provide the proper authentication key instead.

Deepl.new(auth: "DeepL-Auth-Key #{System.get_env("DEEPL_API_KEY")}")

Afterwards, just pass the client to the provided functions:

client = Deepl.new(auth: "DeepL-Auth-Key #{System.get_env("DEEPL_API_KEY")}")
translations = Deepl.translate(client, ["Hello, world!"], "IT", source_lang: "EN-US")

Note that source_lang is optional.

Further configuration

Caching is done with ConCache. You can configure its settings with application environment. Read application.ex.
