Duckula: Type Safe Backend Services with Clojure, HTTP & Avro

on YouTube ↗27m

" summary

Duckula is a small Clojure micro‑framework that enforces Avro+JSON schemas at the HTTP edge, turning every endpoint into a post-only RPC with built‑in automatic validation, standardized logging and metrics, and an opt‑in Swagger UI. Teams share Avro schemas between Clojure and TypeScript, the runtime rejects invalid publishes/requests, and production services report lower debugging overhead after months of use. Tradeoffs: runtime validation adds latency and Avro can’t express all business rules, but correctness and observability measurably improve.
