Duct is a highly modular, server-side application framework for Clojure built around a data-driven architecture. It organizes systems using immutable configuration, enabling clean assembly of components and streamlined development with backward compatibility via Integrant foundations.

Features

  • Immutable, declarative configuration defines application structure
  • Modular system with reusable components (e.g. web handlers, DB, etc.)
  • Supports lifecycle management and runtime merging using Integrant concepts
  • Tooling for scaffolded project creation (Lein template, duct.main alias)
  • Flexible module options: +site, +cljs, +postgres, +heroku, +example, etc.
  • Encourages composability, testing, and clean separation in applications
