holy-lambda VS clj-kondo

This is easily accessible via https://github.com/FieryCod/holy-lambda

https://github.com/FieryCod/holy-lambda + free tier may fit your needs. Also support for babashka or scittle in lambdas. Many options. Looks like every provider has caught up to the cloud function space, so aws, azure, digital ocean, maybe even linode. Maybe shop around.

Check https://github.com/FieryCod/holy-lambda. It supports Clojure, babashka and native.

I'm running Clojure code compiled with GraalVM native for AWS Lambda. Cold start times are low and performance is decent enough, even with CE edition. The whole process is reasonably painless through the use of Holy Lambda https://github.com/FieryCod/holy-lambda

Not quite what you were asking for, but I wanted to chip in as another happy Clojure + GraalVM native user.

This is why holy-lambda-ring-adapter was released. An adapter is a part of holy-lambda project and is already used in production. The adapter supports all the holy-lambda custom backends:

During the weekend I was experimenting with AWS Polly (which is a text-to-speech AWS service) and Babashka in order to demonstrate usage of holy-lambda (a micro framework for running Clojure on the AWS Lambda).

It's my first post here announcing holy-lambda https://github.com/FieryCod/holy-lambda. I've resisted posting it for almost two years since it was far from being production-ready software. On the other hand, today, holy-lambda reached version 0.1.45 with some great features and fixes included. It's high time to show this project publicly.

My best suggestion here would be clj-kondo with flycheck-clj-kondo in Emacs. I really can't recommend it enough and would have killed to have it when I was learning Clojure. Not only will it underline all of those references to (now) undefined vars, but it can tell you about numerous little mistakes like mixing up arguments orders in (say) sequence functions, misplaced docstrings that get discarded, style conventions, etc. It's staggering how good it is even for a language as dynamic as Clojure.

The clj-kondo linters are worth reading.

Sure!

Spec: https://github.com/edn-format/edn

Example (linter config): https://github.com/clj-kondo/clj-kondo/blob/634294183a0aa2ca...

Clj-kondo doesn't produce an AST but you could easily combine the analysis output with the AST produced by rewrite-clj by matching on location.

But if you want full support, you can implement a hook: https://github.com/clj-kondo/clj-kondo/blob/master/doc/hooks.md

Please configure and use tools like clj-kondo and kibit. Kibit will report areas where you could write idiomatic clojure instead. Eg, it should catch all those (if (condition) true false) and ask you to replace it with (condition). Or if you really need a boolean value, use boolean to coerce it.

Try clj-kondo, a Clojure linter which will tell you about arity errors and more, before you even evaluate your code.
