Notes.

My team and I were laid off today due to the pandemic. If you’re looking for senior engineers (Clojure or otherwise), then talk to Angus Fletcher, Ian Bishop, Cody Canning, or myself.

That means I’m now looking for a new remote job. I live in New Zealand but work on Pacific Time to sync up with engineering teams in USA and Canada. I have experience using Clojure and ClojureScript, but I’m also open to other languages. You can see my GitHub profile, LinkedIn, and personal site.

If you think I or one of my colleagues could be a good addition to your team, reply to this email and get in touch!

-main

• I talked with Łukasz Korecki about mature Clojure codebases
• Mike Thompson on whether re-frame is virtuous

Libraries & Books.

• Rough for CLJS is a new library that wraps Rough.js to give your graphics a hand drawn style.
• Darkstar is a Clojure library for making SVG’s from Vega and Vega lite specs. This is particularly cool because it uses GraalJS as the script engine to run Vega.

People are worried about Types. ?

• Are tests necessary in Typescript? from Gary Bernhardt.

Foundations.

• Flow Control in Aeron

Tools.

• Bozhidar Batsov has a cornucopia of nREPL updates. What I really like about this post is it shows many Clojure tools are able to benefit from improvements to nREPL.
• Mauricio Szabo talks about nREPL on Chlorine and implementing a nREPL Client.
• Nativity is a tool for turning Babashka scripts into native-images. I imagine this makes them even more portable and can make startup run faster.

Recent Developments.

• There’s a new release of core.async out with support for using JavaScript promises inside a go block.
• An interesting stat I hadn’t seen before; over the last 12 months, unique IPs downloading Clojure from Maven Central went from ~75,000 to ~135,000. Unique IPs is a much better metric to use than raw download counts, raw download counts can sometimes end up counting uncached CI jobs.
• CLJS-1543 Support Closure libs using goog.module.

Learning

• Between Two Parens (still jealous I didn’t think of that name) has a good intro on the various parts of the Clojure CLI tooling suite.
• React Contexts are dynamic scope

Misc.

I’ve been enjoying this new meme of Ghanan dancing pallbearers.

I’m Daniel Compton. I maintain public Maven repositories at Clojars, private ones at Deps, and help fund OSS Clojure projects (along with tons of generous members like Pitch, Nubank, JUXT, Metosin, Adgoji, and Nextjournal) at Clojurists Together. If you’ve enjoyed reading this, tell your friends to sign up at therepl.net, or post a link in your company chatroom. If you’ve seen (or published) a blog post, library, or anything else Clojure/JVM related please reply to this to let me know about it.

If you’d like to support the work that I’m doing, consider signing up for a trial of Deps, a private, hosted, Maven Repository service that I run.

Thanks!
