Bun is released – let’s jump the hype (NO)!

Bun 1.0 was released. And again, the JS ecosystem did what they do best – fell up into hype.

I actually have no idea why this happens so much in JS world; maybe it’s a lack of maturity (I mean, Ruby also did the same in the past, then they figured out it’s not always a good idea to throw away everything when a new stuff appears), maybe it’s something else; maybe people are just desperate to have something better in the JS world – who knows?

Anyway, I decided to do some benchmark tests. I was already not impressed, because I did test Bun in the past, but let’s see what happens with this new version:

The empire built over beach sand

Completely inspired on this post: https://archiloque.net/blog/a-machine-for-gods-jam/, and my experiences with Pulsar.

The Node.JS Ecosystem, together with so many others, is broken. Maybe beyond repair.

Let’s review the foundations of good software: good code, automated tests, a server that checks if the software works (usually called CI Server), a server that publishes the software continuously as soon as everything is working (usually called a CD Server), and reproducibility – meaning, if something fails, it needs to always fail if we send the same parameters, and always fail in the same place in the same way; if it passes, it must always pass on the same condition.

Now, onto Pulsar

My fading frustration with ClojureScript

I’ve talked about at another post on how ClojureScript frustrates me, mostly because I was doing some Node.JS work and Figwheel simply wasn’t working correctly. Now, it’s time to revisit these points:

A little update: I talked a little with Thomas Heller, Shadow-CLJS creator, and he pointed me some issues with this article, so I’ll update it acordingly

Tooling

Figwheel and Lein are not the best tools to work with ClojureScript. Since I discovered shadow-cljs, things are working way better than before: I can reload ClojureScript code from any target, and I’m even experimenting with Hubot (and it works really fine too). The only thing I’m missing is my profiles.clj file, but I can live with that (and I can always use Shadow with Lein if I need profiles.clj).

Also, I’m working on a new package for Atom (and in the future, for another editors too) called Chlorine. One of the ideas is to offer better ClojureScript support (we have Autocomplete now!), using Socket REPL for solutions (even self-hosted REPLs like Lumo and Plank) and even wrap UNREPL protocol in Clojure. So far, is still in the very beginning but things are looking promising!

The stack

Forget Figwheel at all: Shadow-CLJS is probably the best tooling for ClojureScript ever. It auto-reloads ClojureScript code for the browser, for node.js, for node modules, and it integrates with almost everything that you want. It controls release optimizations, have sensible defaults, and even have post-compile hooks (so you can hook Clojure code to do something after some compilation phases). Also, it integrates with node-modules (no more maven-wrappers for JS libraries!) and have some warnings when you use some kind of ClojureScript code that would break :advanced compilation. And, let’s not forget that you can control the refresh reload phase, it adds a userful :include-macros in ns form (that will include all macros from the namespace being required), and controls exports in a sane manner. But first let’s begin with the feature that I found most useful: :before-load-async.
