Module: Roy::After

Defined in:
lib/roy/after.rb

Overview

This module allows you to modify the response before it is sent to the client. It does this by overriding the #call method.

Configuration:

roy.conf.after

A proc object that will be called with the response as argument. Defaults to identity if not set.

Examples:

Forcing a custom content-type


class SetContentType
  include Roy

  roy use: [:after],
      after: ->(resp) { resp.headers['Content-Type'] = 'text/x-foo' }

  def get(_)
    "Hello, world\n"
  end
end

Demo


$ curl -i localhost:9292
HTTP/1.1 200 OK
Content-Type: text/x-foo
