Haha, indeed!

Good point, we'll look into it!

Haha yesss, nerd-sniping is the goal! I believe that there could be quite a few different ways in which this could get solved. The potential solution space is huge, so you might just stumble upon something interesting if you wander places w

Awesome!! They're so great; it's been such a joy to be welcomed into their project. And totally — especially if there is indeed a larger library still waiting to be excavated. Who knows how many completely unique texts are waiting

We don't know. But it's the most fun!

We used approach #1: https://github.com/Zaplib/zaplib/blob/7976d39775dd1642f20d8b... I might write a blog post about this, since it's pretty fun / tricky stuff!

Something clearly went wrong with my fix when testing it — I think we got it now! Thanks again both!!

Yeah, Wasm is quite fast these days, and there is still more room to grow!

by janpaul123 5y ago
Overhead of calling into JS from Wasm is very low; DOM calls are no problem since the DOM call itself is much slower than the overhead of switching from Wasm to JS. See e.g. this article from ~4 years ago: https://hacks.mozilla.o

Oof — sorry for the late response but I'm seeing this too now. Pushed a fix, should be up soon. Tnx for reporting!

Yeah exactly; the headers are such a pain to set up!

Re audio: yeah we currently only use Web Workers and we don't have audio support yet. We do use SAB, but we're thinking of adding support for running without SAB so you can use it with older browsers.

Yeah, might be the continuous animation that we're doing! Or do you mean the startup time? There's definitely still a lot of room for us to optimize stuff :)

by janpaul123 5y ago
Great question! I wrote a blog post yesterday going into the nuances of this a bit: https://zaplib.com/docs/blog_ts++.html The short of it is that Rust+Wasm isn't much faster than highly optimized JS in most situa

That looks awesome! For debugging we support full Rust source maps in the browser (using DWARF). :D (This is something that wasm-bindgen doesn't support, for example!) See https://zaplib.com/docs/developer_environm

Oh cool; you're also using this for robotics I presume (based on your Twitter profile)? Makes sense; lots of data to process there.

by janpaul123 5y ago
Very cool! We do throttle our animations to the screen's refresh rate using requestAnimationFrame, so you shouldn't necessarily get 100% CPU unless the animation takes up the entire "frame budget" (on my machine the main

Safari only very recently added support for threading in Wasm, which we use. Try upgrading to the latest iOS (15.4.1)? It's definitely bleeding-edge stuff; we should add some backwards compatibility for (slightly) older browsers though

Hey HN, one of the creators here! I made it at Cruise because it was super painful to develop https://webviz.io with manual memory management (lots of ArrayBuffers), WebWorkers, etc. I thought that there must be a better way. Ve

If Apple would truly commit to making Swift applications run cross-platform (Windows, Mac, Linux, Android, iPhone, Web/wasm) in a performant way, they could completely take over and become the next stack for performance-intensive appli
