extism VS wasm-pack

Extism can be really useful for packaging up and running cross-language libraries!

The most clear information about it is at: https://extism.org, but its a bit focused on the primary use case for Extism, being a universal plugin system.

There is a C PDK (https://github.com/extism/c-pdk) which you'd probably want to use in a new wrapper around your library in C++, and compile it to wasm32 freestanding or WASI, but without emscripten. Extism doesn't currently have an interop layer to emscripten.

It may just be my own unique obsession to peek at the internals of .wasm, but if anyone else is curious:

u/nbittich - curious if you've tried to use your language as as a scripting language inside other apps? I took a peak at your browser wasm environment, and think we could hook up the `compute` entrypoint you have here[0], but I'm not certain what the `ctx` does without going super deep, and if it could be passed into an Extism function[1] (which is how I'd try to run it from within 16+ other languages).

Yep, this is one of the initial motivations for creating Extism: https://github.com/extism/extism -- and it works across 16 host languages & 8 guest languages.

On the devx, there's definitely some rough edges around building and using Wasm. My company has been working on a framework to ease integrating Wasm into existing applications. One area it focuses on is providing easy data passing between the host program and the Wasm and vice versa. https://github.com/extism/extism We do not have WASI preview 2 support yet, but are interested in integrating it.

Extism handles this really well across 16 or so different languages - and you don’t need to write a whole IDL / schema.

It’s a general purpose framework for building with WebAssembly and sharing code across languages is a great way to put it to work.

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.
