A one-way pipe like the one web_pipe implements can deal with any required
feature in a web application. However, usually, it is convenient to use some
well-known rack middleware, so you don't have to reinvent the wheel. Even if
you can add them to the router layer, web_pipe allows you to encapsulate them
in your application definition.
To add rack middlewares to the stack, you have to use the DSL method
use. The first argument it takes is a Symbol with the name you want to
assign to it (which is needed to allow
injection on
initialization). Then, it must follow the middleware class and any options it
may need:
class MyApp
include WebPipe
use :cookies, Rack::Session::Cookie, key: 'my_app.session', secret: 'long'
end
