RailsConf 2024 - Plain, Old, but Mighty: Leveraging POROs in Greenfield and... by Sweta Sanghavi

Plain, Old, but Mighty: Leveraging POROs in Greenfield and Legacy Code by Sweta Sanghavi Applications exist in changing ecosystems, but over time, they can become less responsive. Controllers actions slowly grow in responsibilities. Models designed for one requirement, no longer fit the bill, and require multi-step deploy processes to change. The plain old Ruby object, the mighty PORO, provides flexibility in both new domain and legacy code. Pair with me on how! We'll explore how we can leverage POROs in our application through some real world examples. We'll use objects as a facade for domain logic in development, and refactor objects out of legacy code to increase readability, ease of testing, and flexibility. You'll leave this session with some strategies to better leverage Ruby objects in your own application.
