ExApiSpecConverter

Elixir Based API Spec Converter that can be used with phoenix_swagger to generate Postman collections for your API. You can also use it to extract in-line documentation to host on Postman. :)

Installation

The package can be installed by adding ex_api_spec_converter to your list of dependencies in mix.exs:

def deps do
  [
    {:ex_api_spec_converter, "~> 0.1.0"}
  ]
end

Usage Convert your specs like so:

   ExApiSpecConverter.convert(filepath, doc_id, coll_name, coll_descr)

Output will be Postman V2 Collection specs.

Assumptions:

1. You're using phoenix_swagger to generate your swagger 2 API specs and in-line documentation like so in your controllers:

def swagger_definitions do
    %{
      Book: swagger_schema do
        title "Book"
        description "Book"
        PhoenixSwagger.Schema.properties do
          genre [:string, "null"], "genre of book", example: "Fantasy", required: true
          name :string, "Name of book", example: "Harry Potter and the Chamber of Secrets", required: true
          author :string, "Author of book", example: "JK Rowling", required: true
        end
      end
    }
  end

    get "/books/:id"
    summary "Get All Books"
