Interfaces

Thick provides interfaces to control it's behaviour.

Asynchronous responses

Asynchronous responses provide functionality to stream response to the client by chunks.

To enable streaming, run

env['thick.response'].chunked # For chunked encoded stream
env['thick.response'].streamed # For raw stream

and define "thick.async" callback in environment, so it reacts to "call" and takes one argument

env['thick.async'] = proc do |response|
  # do something here
end

now simply respond as usual. Once the headers and the basic content is sent, the callback will be invoked.

To write content to the stream use

response.writeContent("some content")

and do not forget close the stream once done

response.close

Example using Sinatra

require 'sinatra/base'

class App < Sinatra::Base

  get '/' do
    env['thick.async'] = proc do |response|
      (1..10).each do |i|
        response.writeContent(i.to_s)
        sleep(1)
      end
      response.close
    end
    env['thick.response'].chunked
    "0"
  end

end

run App
