Rack::Berater

Limit incoming Rack requests with Berater.

Transform limit errors into HTTP status code 429

require 'rack/berater/railtie'

Customize the rack response returned when a limit error occurs:

• status_code - which HTTP status code
• body - what message
• headers - hash of headers

require 'rack/berater'

Rails.application.middleware.use(Rack::Berater, status_code: 503, body: 'slow down yo')

Add a limiter to every incoming rack request.

require 'rack/berater'

Rails.application.middleware.use(Rack::Berater, limiter: Berater::ConcurrencyLimiter.new(key, capacity))

Register exceptions to be handled by Rack::Berater

Rack::Berater::ERRORS << NoMemoryError
