Jason Clark explains the Rack HTTP library from top to bottom, showing how to build APIs and write reusable middleware.

RailsConf 2017: Rack ‘em, Stack ‘em Web Apps by Jason Clark While Rails is the most common Ruby web framework, it’s not the only option. Rack is a simple, elegant HTTP library, ideal for microservices and high performance applications. In this talk, you’ll see Rack from top to bottom. Starting from the simplest app, we’ll grow our code into a RESTful HTTP API. We’ll test our code, write reusable middleware, and dig through what Rack provides out of the box. Throughout, we’ll balance when Rack is a good fit, and when larger tools are needed. If you’ve heard of Rack but wondered where it fits in the Ruby web stack, here’s your chance!

What people say. Recommended as an excellent visual explanation of how Rack middleware sits between web servers and frameworks.

On “What is Rack middleware?”

Rack is a gem which provides a simple interface to abstract HTTP request/response. Rack sits between web frameworks (Rails, Sinatra etc) and web servers (unicorn, puma) as an adaptor. From above image this keeps unicorn server completely independent from knowing about rails and rails doesn't know about unicorn. This is a good example of loose coupling, separation of concerns. Above image is from this rails conference talk on rack link to this video I recommend watching it for deeper understanding.
