Ring and Compojure Web Fundamentals

Use this section to evaluate Ring and Compojure Web Fundamentals as a production Clojure concern, not as a one-for-one replacement for a Java framework pattern. The child lessons show where the boundary belongs, what data should cross it, and which JVM habits are still useful.

Before moving on, identify the smallest runnable example that proves the concept. Add production concerns such as logging, validation, security, or deployment only after the data flow is clear.
