Relax2

Relax2 is a quick and dirty HTTP API client factory for Ruby.

## petstore.rb
require 'relax2'

base_url 'https://petstore.swagger.io/v2'

interceptor :json_request
interceptor :print_response

Then enjoy your API calls.

% ruby petstore.rb GET /pet/2
{"id":2,"name":"doggie","photoUrls":[],"tags":[],"status":"available"}

$ echo '{"id": 2, "name": "NEW DOG", "status": "unavailable"}' | ruby petstore.rb PUT /pet
{"id":2,"name":"NEW DOG","photoUrls":[],"tags":[],"status":"unavailable"}

If you want to create more detailed client, use the modular style with Relax2::Base.

require 'relax2/base'

class ExampleApi < Relax2::Base
  base_url 'http://example.com/api/v1'

  interceptor -> (request, perform_request) do
    puts request.path
    puts request.body
    response = perform_request.call(request)
    puts response.status
    puts response.body
    response
  end
end

# Request manually
request = Relax2::Request.from(args: 'GET /hogehoge q=xx USER-Agent: Hoge/1.23'.split(' '))
response = ExampleApi.call(request)

# or, simply work with CLI args :)
ExampleApi.run
