isn’t it just a “normal” js runtime?

sci should work with it just fine

Yeah like #bebo this could be another thing. Performance numbers look nice and interestingly uses javascriptcore not v8

still feels kind a “yet another SPA framework every hour” situation few years ago 🙂 but for now it is “yet another JS runtime” just two weeks ago I found this - https://hermesengine.dev/

Yeah pretty much. True for the whole js ecosystem I feel. I'm just thinking where and how more clj(s) can be snuck into 😆

Also the current trend seems to be with things like jsx, ts etc is to compile on the fly and not precompile. Both deno and bun favour this.

It's interesting, thanks for sharing

Where did you hear about bun? I completely missed this

Oh, it's 2 on hackernews now ;)

I'm trying out bun + nbb now. It seems to work... ish

So, this works in bun:

// loadFile is silently failing in bun, so we use loadString instead:
import { loadString } from 'nbb'

const code = await Bun.file('index.cljs').text();

await loadString(code);

> Where did you hear about bun? From the same nvim person I told you about, also a name in js/ts world from Netflix 😄 he was doing a live hack on it yesterday before it got open sourced

Added some docs here: https://github.com/babashka/nbb/blob/main/doc/bun.md

Published a new version of nbb which fixes the readFile issue and updated the docs

do you see any significant perf difference? this is a different js engine after all

startup with bun run nbb is much faster than say npx nbb . Haven't measured actually performance. Going to try the loop example now

Similar

I think the most benefits I see is the much faster npm tooling

right, i guess the focus is on fast startup for edge computing than runtime perf

is it in the bb ballpark for startup times 😛 ?

I'm at around 100ms now for nbb, about 50ms is from Node itself

And with deno compile I'm at 80ms

But bb is still the king of startup ;)

I have some places where I can cut some JS size from the bundle still, so more speedups coming. Will never be faster than node startup time because I can't cause negative startup time

Anyone played with nbb + bun + bun:ffi yet? ;)
