Clj-kondo just got 10% faster due to switching from a map to a record representation #clojure #cljKondo

SCI on ClojureDart now released. Have fun making a scriptable mobile Flutter app. #clojure #clojuredart #sci

Squint core functions are now protocolized on main. This means you can bring your own immutable collection like immutable.js #clojure #clojurescript #squintcljs squint-cljs.github.io/squint/?src=...

Clojure 1.13-alpha fun in clj-kondo! #clojure #cljKondo

SCI on ClojureDart coming soon #clojure #clojuredart #sci

Babashka.fs is now available on Node.js (and bun, etc)! Available for CLJS, squint, nbb and directly in JS! github.com/babashka/fs/... #clojure #babashka #nbbcljs

I'm pleased to announce the first release of Reagami in 7 months! Highlights: - Key-based reconciliation - Benchmarks: Reagami is in React-ballpark yet at 10% of the bundle size. Squint perf > CLJS perf. github.com/borkdude/rea... #clojure #clojurescript #squintcljs

Babashka CLI is now available for use in Squint and JavaScript! #babashka #squintcljs #clojurescript

The newly released version of squint can now run (a mildly modified) version of replicant: github.com/squint-cljs/... The Replicant TODO example app comes in around 18kb gzipped. (Reagami ~ 5kb, Replicant in CLJS ~42kb) #clojure #clojurescript #squintcljs

New blog post! Automatic help and completions in Babashka CLI :babashka: blog.michielborkent.nl/babashka-cli... #clojure #babashka

New SCI release with a new feature! #clojure

New blog article! Finding transitive var usages with clj-kondo blog.michielborkent.nl/clj-kondo-ca... #clojure #cljKondo

#babashka, the ultimate tool to smuggle in some #clojure at work? 🤭

Tetris game in bb. Oneliner to run it: bb -e '(load-string (slurp "https://raw.githubusercontent.com/babashka/babashka/refs/heads/master/examples/tetris.clj"))' #clojure #babashka

Tetris in squint + reagami. Source available via link. #clojure #squintcljs squint-cljs.github.io/squint/?src=...

Finally squint has browser nREPL support in the latest release! github.com/squint-cljs/... #squintcljs #clojure #clojurescript

Finally working on the squint browser REPL again. It's going to be based on vite which takes care of hot reload and vite will start the nREPL server too which you can REPL into with emacs etc, so it's going to be just vite dev.

Released a special #cljKondo version today. It's able to execute macros from source (under certain restrictions) + support for CLJS async (syntax.+ linters) + more! #clojure #cljKondo

ClojureScript async function reference clojurescript.org/reference/as... #clojure #clojurescript

Any thoughts about flying to conferences and climate change? When do you justify it for yourself and when not?

That was a great day at #babashka_conf. Now a short night sleep and on to #clojuredays!

ClojureScript 1.12.145 is out, featuring async/await. clojurescript.org/news/2026-05... #clojure #clojurescript

Getting all hyped up for #babashka_conf and #clojuredays!

Clj-kondo loading a macro from source using the :clj-kondo/macro annotation. Helper fns should also be annotated. The only restriction is that vars used in the macro at compile time are available in the SCI env where the macro runs (so clojure.core, set, walk, etc). #cljKondo #clojure

#cljKondo WIP #clojure

EuroClojure is back. In 2027. In Prague! Wow 😍 ! 2027.euroclojure.org #clojure #clojurescript

Last call! Two more days to send in a talk proposal for a full or lightning talk for Babashka Conf 2026! babashka.org/conf/#cfp Thanks to Nubank, Exoscale and Bob for sponsoring the conf! We are looking for one last sponsor to provide a snack during the coffee break! ❤️ #clojure #babashka

Wanna try a faster alternative to jbang using GraalVM native-image + Crema? github.com/borkdude/cre... ~20-30ms for executing Java "scripts" with dependencies. It's a shame the name JavaScript was already taken! #clojure #graalvm #java

New experiment! github.com/borkdude/cream Fast starting Clojure runtime built with GraalVM native-image + Crema Crema is a JVM bytecode interpreter which allows you to dynamically evaluate stuff inside of a native-image. #clojure #babashka

#babashka is the most popular Clojure dialect after JVM Clojure 😎 #clojure clojure.org/news/2026/02...

Babashka 1.12.215: Revenge of the TUIs blog.michielborkent.nl/babashka-1.1... One of the most exciting babashka release thus far! (If you encounter the blog post link on HN, please upvote it (please don't share a direct HN link as this is penalized by HN's algorithm). Thank you!) #clojure #babashka

Only 3 weeks to send in proposal for #babashka_conf! babashka.org/conf/#cfp Thanks to Nubank, Exoscale and Bob sponsoring the conf! Check out their hiring links at the bb conf page! We have room for one more platinum (500) or gold (250) sponsor to cover costs. #clojure

New SCI version dropped which now supports async/await in CLJS! And new #nbbcljs dropped which uses the newest SCI. Demo: $ npx [email protected] Welcome to nbb v1.4.206! user=> (defn ^:async foo [] (let [x (await (js/Promise.resolve 1))] (inc x))) #'user/foo user=> (foo) #<Promise 2> #clojure

Seems like I'll be doing a lighting talk at DCD: Bringing async/await from Squint to ClojureScript! (Perhaps a full talk later in the year somewhere else?) #clojure #clojurescript

The next #babashka version will have an improved console REPL. No more rlwrap needed. Multi-line expressions can be entered and edited. Moreover: completions! Test out the dev version with: bash <(curl raw.githubusercontent.com/babashka/bab...) --dev-build --dir . #clojure

This snake game is now playable with the babashka dev build which includes jline! gist.github.com/borkdude/21f... Install the dev build with: bash <(curl raw.githubusercontent.com/babashka/bab...) --dev-build --dir . #clojure
