Component model can run in any js runtime with jco

I wonder if this mess has anything to do with talent loss resulting from layoffs after the pandemic

Wasm is safer since it has a much smaller attack surface.

Sorry, here's the working link https://github.com/mendyberger/browser.wit

It's not just about string performance, it's about making wasm a first class experience on the web. That includes performance improvements - because you don't need to wake up the js engine - but it's a lot more than that. Including much better dev-ex, which is not great as you can see in the OP.

It would also enable combining different languages with high-level interfaces rather than having to drop down to c-style interfaces for everything.

Things are slowly getting better in wasm world.

The c-style interface of wasm is pretty limiting when designing higher level interfaces, which is why wasn-bindgen is required in the first place.

Luckily, Firefox is pushing an early proposal to expose all the web apis directly to wasm through a higher level interface based on the wasm component-model proposal.

I think you're missing the point they're trying to make. It's not that the problem isn't real, it's that the solution won't work. Kids will find a way around. They have a lot more free time than us.

There can be an automated way of translating WebIDL to wit.

I've actually tried to do that the past and got pretty far. https://github.com/wasi-gfx/webidl2wit

And here's the generated wit https://github.com/mendyberger/brow

Modern languages come with lots of interesting features like better dev ex, null safety, etc. Js is a fine language, but there are other languages that bring unique advantages, the web shouldn't block developers from using better tools. The web is best off when developers have freedom.

Is `component {}` valid wit syntax? I've never seen that before

Some real misconceptions here

Bit of a nitpick, but I don't think saying things like this to normies is a good idea. Every system is hackable.

As someone who very interested in wasm, I really loved the post!

Fair enough.

For me, having wgpu's rust native api feels so much nicer than having to deal with the unergenomic web_sys api. Tradeoffs.

Curious, why use web-sys directly instead of wgpu?

Can happen to corporate projects as well. As one example, look at how many projects Google has killed.

After restarting my computer, reinstalling git, almost ready to reinstall my os, I find out it's not even my fault

But the other browsers objected yet Chrome still shipped them

Not true about webgpu, but true about some APIs in Google's project-fugu

Kind of a dumb question, but how does it work if you have a 10 year non-compete in FL but move to another state after 5 years, is the non-compete valid in the other state?

Firefox doesn't support WebGPU in stable yet. Chromium does support WebGPU in stable, but not on Linux.

Code is actually tiny. Impressive!

You could make it even smaller by removing all the element names, and just have it be passed in as an argument. Would also reduce the amount of functions you need to declare, though function count is likely not a problem for modern JS engines.

Anyway, great job you did there!

This? https://github.com/WebAssembly/wasi-webgpu

Readme says it's a C++ library. Any plans to support higher level languages such as Go or even Python?

Cool project!

Looks like it supports geometry and textures now, any plans to support shaders?
