From: Automatic build Fails fast with Failing fast with Turning on Pretty Errors will give much nicer error messages: NOTE: Below is an example of using expound to pretty-print route data problems. Invalid spec value: Explicitly requiring a To fail-fast on non-defined and misspelled keys on route data, we can close the specs using Requiring a It catches also typing errors: clojure.spec validation turned on:clojure.spec validation turned on:
