I'm working on a clojurescript project right now that compiles to 80K lines of javascript (using the most basic compilation level during development). In my actual workflow I've found that the compilation takes under 250ms each time. I have it auto-compiling every time I save the file using the lein cljsbuild plugin and it's near instant as far as I'm concerned.

Do you mind giving a quick rundown of how you set up your environment, or at least a point in the right direction?

The most barebones version is very simple: lein has a plugin called lein-cljsbuild. In your project.clj there is a way to specify the directories this program needs to watch for file changes. lein cljsbuild has an option "auto" which activates the directory watcher and automatically recompiles the cljs files when one of them changes.

This long-running program keeps the same jvm running for all the compiles, and lets you iterate more quickly.

How are you finding the ClojureScript REPL? I wanted to play around with it, but gave up after finding out how much trouble it is to get running. I was hoping it would be as simple as Clojure's `lein repl`.

It's a bit harder to set up but it's very much worth it once you have it running. I use clojure.browser.repl

Thank you, I'll look into it!

That was not my experience with Clojurescript. I might have to try it again.
