component-model VS enarx

I don't think that's a very good goal. Jettisoning the DOM means jettisoning accessibility and being able to leverage everything that the browser gives you out-of-the-box. You have to render to a canvas and build everything from scratch. I think Wasm is great for supplementing a JS app, not replacing it (e.g. using a Wasm module to do some calculations in a Worker). I like to use the right tool for the job, and trying to use something other than JS to build a web app just seems a little janky to me.

At one point, there was a Host Bindings proposal that would enable you to do DOM manipulation (it looks like it was archived and moved to the Component Model spec [1]). That would probably be the ideal way to avoid as much JS as possible. However, browser vendors have been heavily optimizing their JS runtimes, and in some cases, Wasm may actually be slower than JS.

I've been following Wasm's progress for several years, which has been slow, but steady. Ironically, I think the web is actually the worst place to use it. There's so much cool non-web stuff being done with it and I'm more interested to see where that goes.

Well the great thing about WebAssembly is that you can port QT or anything else to be at a layer below -- thanks to WebAssembly Interface Types[0] and the Component Model specification that works underneath that.

To over-simplify, the Component Model manages language interop, and WIT constrains the boundaries with interfaces.

IMO the problem here is defining a 90% solution for most window, tab, button, etc management, then building embeddings in QT, Flutter/Skia, and other lower level engines. Getting a good cross-platform way of doing data passing, triggering re-renders, serializing window state is probably the meat of the interesting work.

On top of that, you really need great UX. This is normally where projects fall short -- why should I use this solution instead of something like Tauri[2] which is excellent or Electron?

While I don't necessarily agree with the unnecessary, unsupported casual, & cheap contempt culture here ("unshackle the web from the mess that is JavaScript", "places that don't really need these problems to be solved")...

WebAssembly component-model is being developed to allow referring to and passing complex objects between different modules and the outside world, by establishing WebAssembly Interface Types (WIT). It's basically a ABI layer for wasm. This is a pre-requisite for host-object bridging, bringing in things like DOM elements.

Long running effort, but it's hard work and there's just not that many hands available for this deep work. Some assorted links with more: https://github.com/WebAssembly/component-model https://www.fermyon.com/blog/webassembly-component-model https://thenewstack.io/can-webassembly-get-its-act-together-...

It's just hard work, it's happening. And I think the advantages Andy talks to here illuminate very real reasons why this tech can be useful broadly. The ability to have plugins to a system that can be safely sandboxed is a huge win. That it's in any language allows much wider ecosystem of interests to participate, versus everyone interested in extending your work also having to be a java or c++ or rust developer.

A. Sure, but it isn't sufficiently beneficial for the cost.

B. WebAssembly is immature for developing a plugin system because of the lack of a sufficient ABI: https://github.com/WebAssembly/component-model

C. There aren't any other languages that meet the criteria. Lua was a no-go from the start. The maintainers did not like the language, and it necessitated adding more C code to Helix which could complicate building even further. https://github.com/helix-editor/helix/discussions/3806#discu...

AFAIK GC is irrelevant for "direct DOM access", you would rather want to hop into the following rabbit hole:

- reference types: https://github.com/WebAssembly/reference-types/blob/master/p...

- interface types (inactive): https://github.com/WebAssembly/interface-types/blob/main/pro...

- component model: https://github.com/WebAssembly/component-model

If this looks like a mess, that's because it is. Compared to that, the current solution to go through a Javascript shim doesn't look too bad IMHO.

The wasm idl (called WIT) is actively being worked on here: https://github.com/WebAssembly/component-model/blob/main/des...

Being able to access DOM is definitely an objective. It's just taking a lot longer than folks guessed to build a modular wasm ABI.

Take a look at the python abi to see what the structure looks like for calling into components https://github.com/WebAssembly/component-model/tree/main/design/mvp/canonical-abi

Do you mean a trusted execution environment, like Intel SGX? GPUs live outside the TEE, so, no, I think what you're asking for isn't possible. But for doing TEE stuff in Rust, see https://enarx.dev/ .

Keep in mind that I'm using "OS" here loosely; it's a bare-metal program that exposes a subset of Linux syscalls so that the interpreter (which itself is compiled for Linux) can run in the extremely strange context that we target. It's still early days so I won't spend too much time shilling it, but all the code is open source and lives under the umbrella of the Linux Foundation: https://enarx.dev/

What do you use to run Wasm on untrusted systems? Is it Enarx by chance?

Here's the project: https://enarx.dev/

There's not much to say about the company just yet, but I'll note that all of our code is open source and the main project itself that we develop and that does most of the magic lives under the Linux Foundation's Confidential Computing Consortium, it's called Enarx: https://enarx.dev/ . TL;DR: use fancy new CPU features to run workloads in the cloud where both the program itself and all the data it processes are hidden from the cloud provider.

This is my second blog of the Outreachy'22 internship. Before this Internship, I never had any strong development experience. This is the opportunity that enabled me to work across a really good technical Project i.e. "The Enarx Project".

The Enarx Project is the part of Confidential Computing Consortium from the Linux Foundation, the folks here are very collaborative and welcoming. As a fellow mentee, I'd like to thank the Community Manager- Nick Vidal sir. In addition to me, he provided the right guidance to all of us contributors and mentored us to the right path. There were many folks who were more proficient than me and were making up numerous commits, but I tried my level best and was focused to contribute as much as possible and ended up making the maximum number of contributions.
