@joao.galrito don't use lein itself in production, use lein uberjar to make a jar, then run it via java

Alright, I had searched online for "deploy clojure apps to production" and a lot of people talked about being fine using lein
2020-10-30T01:55:55.034600Z
the problem is that there's no advantage to lein in production, and there are actual disadvantages (in terms of resource usage, startup time for example)

there are also dedicated libraries for managing long running java programs, eg. jsvc

It is also really simple to write a .service file for systemd (or an rc file if on BSD) for running an uberjar

regardless - don't use lein as a prod launcher, it's just a bad idea
2020-10-26T16:06:49.033800Z
with a .service file how do you handle controlled shutdown - via signal handler?
zilti 2020-10-26T16:09:38.034Z
Well, if you absolutely have to have code run on shutdown, you can use Runtime's addShutdownHook but so far I wasn't in a situation where that was needed
