Some time ago I found out this post: https://petevilter.me/post/datalog-typechecking/. It stroked me as really interesting – because it was an idea to make some IDE not depend on some internal API that only works for a single editor, but somehow make a tooling that’s query able by datalog. This datalog Read more…
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
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!
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
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:
