It's very usable. What you loose in performance, you gain in confidence provided by a statically compiled language. So, you can simply go longer in between reloads without risking too much fall out. If it compiles, it will probably run without a lot of weirdness. So there's less need to feel insecure whether things will still run. Also, I should point out that this is on a largish three year old code base. Re-running tests without recompiling is similarly fast with kotlin-js. A Spring integration test with some code in main and test needing recompilation and the Spring Boot start up time will also set you back 15-20 seconds or so. And as I pointed out webpack is at least half of the time you are waiting these days. IMHO, getting rid of that and replacing it with something faster could be worthwhile.
