I noticed in this https://www.youtube.com/watch?v=zIajwJDi4wY video that there was a (add-dep) control in the Figwheel CLJS repl to add dependencies on the fly during an active session. Is that no longer supported? I do see that in the video it shows that function to be experimental.
I think the experimental feature has been removed. It's been a few years!
Do you perhaps mean clojure.tools.deps.alpha.repl/add-libs?
