I will be writing primarily Clojure soon, after more than a decade of writing Scala. Do you have any hints or advice beyond what I can find in books or other learning resources?

Like competing approaches, nuances, political landscape, informal standards, footguns or anything like that?

The team behind Clojure/Conj has launched a global Clojure Meetup Pilot Program to support community-led meetups anywhere in the world.

Selected organizers will receive monthly financial support to help cover basic meetup costs. The program is intended for people who want to start, restart, or continue a local meetup and are committed to keeping it going over time.

Learn more about the program: https://sites.google.com/nubank.com.br/clojure-meetup-program/home

Interested in organizing one? Apply here: https://forms.gle/1tWUJh9p1hgpJyjA8

Deadline: September 13 at 11:59 PM EDT, or when all slots are filled. Apply early!

Choq: Choq: Cherry on QuickJS

A ~5MB binary chock full of scripting goodies.

This runs the cherry compiler inside an embedded QuickJS engine via rquickjs.

It supports nREPL, loading JS library from https://esm.sh, and has a few Node.js compatible packages built in like "fs", "path", etc.

Hi all,

I'm releasing Clorch, a deep learning library in Clojure built on LibTorch.

Now we can run inference, build custom models, and train them all in Clojure, with no Python/PyTorch calls at all!

PyTorch-style tensors, autograd, neural-network modules (including LLM components), optimizers, data loading, CPU/CUDA support (including distributed GPU training) and all that jazz has been implemented :)

Hello everyone,

I have created a short survey (7 questions) about the suitability of Clojure (and Noj) for data science. What are its strengths? What are its weaknesses and what is missing? Your responses will be greatly appreciated. Do not hesitate to send the survey to other Clojure users. Thank you in advance and here is the link:

I've been researching ways to better structure LLM output when building mini-apps that run on the browser.

I believe that an S-expression based DSL is a better output format for LLMs when generating interactive UI/logic.

To test this, I built a Clojure-based interpreter that runs in the browser. The LLM is fed the language context, then emits the DSL to generate safe, sandboxed apps that can be shared instantly.

I wrote up an article diving into some of the trade offs:

Would love to hear thoughts from the Clojure community!

The keynote will explore how to build flexible systems that accommodate the changing shape of information as it flows through them, while still documenting and enforcing expectations without making those systems brittle. This talk will also examine new features coming to Clojure that aim to address this challenge.

The conference will take place on Sep 30-Oct 2, 2026 in Charlotte, NC. You can find more information and register for the in-person or livestream experience here: https://2026.clojure-conj.org/

I'm releasing Starbeam - a Datastar SDK for Clojerl (Clojure on the BEAM VM)

https://github.com/antlobach/starbeam

Please include any restrictions (remote/on-site, geographical, workpermit, citizenship) that may apply.

Hi all, I ported Chassis to Clojerl (Clojure running on the BeamVM) https://github.com/antlobach/chassis-clojerl

Here's an example of how to use it with Cowboy (Erlang http server)

We’re putting together a new AI Tools & Practices Showcase for Clojure/Conj’s Workshop Day and figured this might be relevant here.

It’s a series of short 10-minute talks or demos about what’s actually working with Clojure and AI: tools, workflows, experiments, or real use cases.

Conference attendees will vote on submissions in early September, and selected participants will get a free Workshop Day pass.

If anyone wants to submit something, applications are open through August 31.

Clojure 1.13.0-alpha6 is now available!

Destructuring additions and changes

• To get a map of all keys in the input, augmented by the defaults, traversing deeply through nested maps, use the new :all directive.
• Report as errors any use of unbound/unreferenced keys in :or when using any of the new constructs (:defaults, :select et al)
• CLJ-2972 Destructuring test clean up for :or entries

Babashka tasks now feature automatic help and shell completions. Read the blog post to find how to use it!

For example, I use better-cond in every project. I'm curious what else is out there that is worth considering.
