Designing a Great Ruby API - How We're Simplifying Rails 5

on YouTube ↗38m

" summary

Describes designing and shipping a concrete replacement for ad hoc attribute casting in Rails by extracting a reusable type object, adding lazy and strict APIs, and layering attribute decorator and attribute collection objects to replace the giant case statements that lived on the columns hash. Tests guide incremental refactors, many changes land in 4.2 with the API becoming public in Rails 5, bugs drop significantly, and performance stays roughly the same after eliminating string-keyed hashes and consolidating behavior.
