How would it be any different from Electron if it bundled a JS/Webassembly engine (V8, which it already does) and a HTML canvas renderer (which would most likely be Blink)?
That’s still only part of what you need. You could pretend the native window client area was a <canvas> and give the code a GPUCanvasContext that renders to it, but you still need to do something about handling user input, what happens when the window size changes, &c. &c. And if you’re working with such minimal primitives, you won’t be able to make something that looks or feels even vaguely native.
The browser gives you a lot of valuable functionality.
This is all trivial (in fact much, much easier) to do with a handful of tiny custom APIs instead of what HTML5 provides (there are plenty of native window system glue library examples which have much saner APIs for window and input handling: GLFW, a subset of SDL, winit...).
Rendering an UI that even remotely looks "native" is harder with HTML+CSS than a handful of straightforward rendering primitives which can be implemented on top of WebGPU.
High quality text rendering is a bit non-trivial of course, but that's also only an issue if you want to do a native-looking UI (but mostly irrelevant for games).
The browser WebGPU implementations are available as native standalone libraries and are fairly easy (YMMV, especially for Dawn) to integrate into regular native applications:
No it's not. WGPU (a WebGPU renderer built with rust) which is what Deno is using under the hood in this change, works perfectly well and is used by many other projects.
Even if that were not the case Chrome's WebGPU implementation is also available separately and it's called dawn.
This whole thread is confusing. The blog in the OP, the comments section of which are you posting in right now, is literally about adding WebGPU support to a headless JavaScript interpreter Deno, that includes no HTML/CSS/DOM/Windowing engine. WebGPU is a standardized API built on platform specific graphics APIs, it is not a "renderer". The WebGPU support is based on wgpu, which isn't used in Chromium; it's actually the basis of Firefox's WebGPU implementation (and widely used by most Rust WebGPU projects, such as Bevy.) The person you are replying to simply wants native windowing APIs added to Deno as well, which has been done about 1,000,000 times in various other languages.
I'm very confused because every comment you have posted in this reply chain makes no sense in the context of the actual blog.
