The article shows how to use the Zeitwerk gem to autoload classes and modules in a Ruby app that's not using Rails. It explains the concept of models in a Ruby web application and how to load them with Zeitwerk. Zeitwerk is a gem written by Xavier Noria, a member of the Rails core team, that allows classes and modules to be automatically loaded without the need for explicit requiring. The article also mentions the mrsk gem, which uses Zeitwerk internally. It covers the problem that Zeitwerk solves and provides step-by-step instructions on how to use it outside of Rails. Additionally, it introduces the concept of models and demonstrates how to create a new model called Article in a no-Rails app. Models help organize data and encapsulate related variables and operations.
