Extension integrating with rack session

[waiting-for-dev]

Wrapper around Rack::Session middlewares.

This extension provides with helper methods to retrieve rack
session and work with it while still being able to chain Conn
method calls.

It requires one of Rack::Session middlewares to be present.

require 'web_pipe'

WebPipe.load_extensions(:session)

class MyApp
  include WebPipe

  use Rack::Cookie, secret: 'top_secret'

  plug :put_session, ->(conn) { conn.put_session('foo', 'bar') }
  plug :fetch_session, ->(conn) { conn.put(:foo, conn.fetch_session('foo')) }
  plug :delete_session, ->(conn) { conn.delete_session('foo') }
  plug :clear_session, ->(conn) { conn.clear_session }
end
