Dissecting Rails

on YouTube ↗28m

" summary

Rails breaks into reusable pieces: Bundler and Rake are shown as independent tools, Rack runs a web app in three lines of code, middleware handles logging/APM, ActiveSupport adds methods like array.42, ActiveRecord and ActionMailer run entirely outside Rails with minimal setup, ERB templates render by calling ERB.new and .result, and DSL patterns explain routes/rspec styles. Two hands‑on exercises walk through a Rack app with middleware and a small ActiveRecord+ERB+ActionMailer lambda that actually sends emails.
