Is there any “official” docker image for clojurescript + node + clojure cmd instead lein ?

not that I'm aware and you probably won't see anything like that from the core team

ok, thanks for feedback

announcing this new npm library for react-native https://github.com/bhauman/react-native-figwheel-bridge

and figwheel

AWESOME! super excited to see anything moving the needle on RN + CLJS 😄

does this remove metro from the workflow?

no no no

😉 wishful thinking

@lilactown did you see https://kevinlynagh.com/notes/fast-cljs-react-templates/ ?

yeah! super interesting

what was the name of your library?

https://github.com/Lokeh/hx

I’m taking the “runtime interpretation, possibly slow templates” approach right now 😛

yeah that’s not the best 🙂 and its really not good for react-native

I’ve seen some pretty slow screens render in reagent

but it is incredibly interesting. I went down the macro hole earlier this year and like he outlines in the article, found it frustrating and dangerous for new users to figure out what was interpreted vs. not

I could play some tricks to get certain things to compile but then that just ended up being even more confusing when it didn’t

I get it but I think this approach that uses inference is really good

and the hybrid approach can still save lots of invocations

yeah I think it’s awesome

we actually need some good numbers though

I’ve done some tests that show a X2 speed up

yeah, I was thinking about last night how best to do a benchmark of the actual cost of the runtime hiccup interpretation vs compilation

and 2x speed up makes a difference when you are trying to render at 60 fps

yeah absolutely. I’m kind of surprised at that number but if that’s true, woof

but to be fair this really only matters on large node counts

I’m guessing it grows… yeahh

actually I could build the render timing into the figwheel-bridge

and I wonder how it changes with large trees of shallow components (so you’re calling the interpreter many many times) vs. deep components, shallower total tree

that could be nice to have!

and its really the initial render that matters when changing screens

incremental renders should be comparatively minimal

I’ll play with this more today. I have a project that I’m going completely into outer space with; using hx + a fork of re-frame, [email protected] and hooks, all the new toys.

replacing hx’s hiccup compiler with kevin’s hicada fork is easy

thats awesome 🙂

how do you check if something is defined in js/window? ie, if ('requestIdleCallback' in window)

(exists? (.-requestIdleCallback js/window)) ?

thanks. will try

goog.object also has containsKey

much appreciated
