LowLoop is an asynchronous event-driven server that sents RequestEvent's to LowEvent. Finally you can see and track events through every step of your application, from the request layer right through to the application and data layers. Simply add observe 'users/:id' to a LowNode and now it will be called every time a request is made to this route.
Test things are working with:
bundle install
LOW_MIRROR=1 bin/start
The server will start a demo server in mirror mode, mirroring all of your requests as text in the response.
