REPL driven development

on YouTube ↗35m

" summary

Demonstrates using a REPL to build a Tomcat-backed REST service live: start Maven/Tomcat (~30 seconds), attach an IDE to a Clojure REPL via rebel socket, query JDBC metadata to discover tables and a stored proc named transactions_in_tvp, call it and paste the real result into tests, then drive TDD and controller wiring without full redeploys. Tests run automatically and only the affected subset runs; state can be preserved across reloads selectively. Claim: far fewer surprises on startup and much faster feedback than rebuild cycles.
