Clojure West

Domain driven design with Clojure

• Organizing larger applications
• Domain logic shouldn’t include handlers for bad/unclean data.
  • validateur, bouncer, clj-schema for checking data going into the pipeline.
  • domain-specific, semantic checks
  • TODO: Any better ways for doing this conditional validation.
  • Need to factor out common data cleaning utils into shared library.
