I'm grateful to @djblue for Portal. Today, I've been working with one of our legacy (non-Clojure) apps that calls into Clojure and with a Socket REPL (via a JVM option), VS Code/Clover, and Portal, I've been able to work live via the REPL inside our legacy application as I'm working on rewriting the legacy code into Clojure. It's wonderful having my normal development workflow completely available with data visualization and navigation inside my editor even tho' I'm not working with our modern Clojure apps.
