Allusion VS wasm-pack

Allusion? https://github.com/allusion-app/Allusion

You can only block a web worker thread; blocking in the main thread is not allowed by browser vendors. If you want to synchronize two web workers, you can use the std primitives like Mutex and compile with atomics. If you want to synchronize the main thread and a web worker, you need to build this yourself. I have implemented this in one of my code bases (https://github.com/allusion-app/Allusion/blob/master/wasm/masonry/src/sync.rs) but the code is GPL licensed. Note this particular code only works in browsers that support Atomics.waitAsync. An alternative is to wrap a worker.onmessage callback in a Promise and await that. Also statics are used because I don't want the overhead of calling receive from JavaScript back to Rust in the web worker, not that they are required.

One idea that could work out is to move state management to a web worker and state changes are just messages between the main thread and web worker (JS example with Redux + React + Comlink. The Redux and Comlink would be reimplemented in Rust (requires atomics, WASM intrinsics and however Redux works). However, using atomics is not so nice. Atomic.waitAsync has so far been only stabilized in Chrome last time I used it and the Rust std library has no equivalent, so you still have to call that from Rust. I've implemented something similar to a channel/spinlock but with statics (github source).

The final implementation: Masonry algorithm in Rust, Webworker, Masonry renderer which makes use of the Virtualized renderer

For a much simpler but less flexible approach there's wasm-pack for creating JS packages from Rust, and wasm-bindgen for easy interop. Both have very good documentation.

After four years, I found some time to pay that deb-tech (yes, quite a long time, eh). To make it fun I rewrote everything from scratch in SolidJS, which went smooth thanks to this amazing library p5js-wrapper. For WASM, C++ is still a good choice, but what about Rust? I did some research and found wasm-pack. A few lines in the cargo.toml file and we were ready to generate compiled + ready to import bytecode!

Support using wasm-pack in Worklets (particularly AudioWorklet) #689

If you're looking to use it to interface with node/browsers, then try wasm-pack.

Webassembly: wasm-bindgen 0.2.83 / wasm-pack 0.10.3

wasm-pack has bugs - it publishes a module which declares itself as a commonjs module. (You can fix that by manually adding "type": "module" in package.json). Then the web build should work with other bundlers. I opened an issue about this over a year ago. There's a PR and everything, but no movement :/

wasm-pack helps you build Rust-generated WebAssembly packages and use it in the browser or with Node.js.

Is the Rust WASM ecosystem being half dead better? wasm-pack and wasm-bindgen are barely maintained anymore, and trust me it's not because everything works flawlessly…

I've been learning Rust for the past few weeks and have been enjoying it a lot.

- The community is very helpful on Discord (https://discord.com/invite/rust-lang-community).

- The package ecosystem (crates.io) makes it very easy to find and import things, and they're consistently documented.

- There's a path to compiling on web via WebAssembly (https://rustwasm.github.io/wasm-pack/)

In a few weeks of learning the language, I managed to put together this visualization: https://twitter.com/admiralakk/status/1542560489091350529

But realistically, either Go or Rust will be fine. You should pick the one you're more likely to stick with and learn, even when it gets tough. I've found the community aspect to be very helpful, because then at least I know I'm not the only idiot out there.

There are various ways to set up a web project that uses Svelte, Wasm, and Rust. For example, wasm-pack from the rust-wasm group provides a template for simple HTML-CSS-JS applications. There are also several project templates for React or Svelte with Rust and Wasm.
