Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

WASM by Example
The component model is already shipping in Wasmtime, and will be stable for use in Node.js and in browsers via jco (https://github.com/bytecodealliance/jco) soon. WASI Preview 2 will be done in December or January, giving component model users a stable set of interfaces to use for scheduling, streams, and higher level functionality like stdio, filesystem, sockets, and http on an opt-in basis. You should look at wit-bindgen (https://github.com/bytecodealliance/wit-bindgen) to see some of the languages currently supported, and more that will be mature enough to use very soon (https://github.com/bytecodealliance/componentize-py)
Right now jco will automatically generate the JS glue code which implements a Component Model runtime on top of the JS engine's existing WebAssembly implementation. So, yes, Components are a composition of Wasm Modules and JS code is handling passing values from one module/instance to another. You still get the performance benefits of running computation in Wasm.
One day further down the standardization road, we would like to see Web engines ship a native implementation of the Component Model, which might be able to make certain optimizations that the JS implementation cannot. Until then you can consider jco a polyfill for a native implementation, and it still gives you the power to compose isolated programs written in many languages and run them in many different contexts, including the Web.
(Disclosure: I am co-chair of WASI, Wasmtime maintainer, implemented many parts of WASI/CM)

Spin 2.0 – open-source tool for building and running WASM apps
Thank you!
To your point, the primary consideration for choosing the languages is their support for WebAssembly, and WASI in particular.
Due to Spin's heavy use of WASI and the component model, languages that have first party support in the WIT bindings generator (https://github.com/bytecodealliance/wit-bindgen) are the easiest to implement, followed by languages that can be built on top of the support for those with first party support.
For example, the JavaScript support is built by embedding QuickJS (in particular, Shopify's Javy project — https://github.com/fermyon/spin-js-sdk), which then uses the Rust SDK.

Rust + WASM + Typescript [+ React]
There are many options, but what worked best for me is compiling with cargo-wasi and loading the resulting Wasm file with browser_wasi_shim. Using wasm32-wasi instead of wasm32-unknown-unknown requires a bit more work (the communication with JS has to be set up manually), but gives the flexibility of having just a Wasm file that can be dropped in and loaded dynamically. (There's wit-bindgen for generating wrapping code according to an interface definition but I didn't have much success with it.)

Introducing - Wasmer Runtime 4.0

Using WASM for a plugin system in Rust? (generate code at runtime and then hot reloading it as a library)
Yep, you're right. For this, there are a few options. The ones most relevant to you are fp-bindgen, which targets Wasmer, and wit-bindgen, which targets wasmtime.

Introducing Ambient 0.1: a runtime for building high-performance multiplayer games and 3D applications, powered by Rust, WebAssembly and WebGPU
Are you evaluating if WebAssembly Component Model, its WIT format and related tooling like wit-bindgen could be a good fit for your multiple languages support?

Faces.js, a JavaScript library for generating vector-based cartoon faces
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.

Show HN: Now my pet programming language can run in the browser
It may just be my own unique obsession to peek at the internals of .wasm, but if anyone else is curious:
https://modsurfer.dylibso.com/module?hash=ab6f4b2de9db171347...
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).

WebAssembly Playground
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.

WASI 0.2.0 and Why It Matters
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, the universal WASM framework, reaches 1.0
- Extism, the WebAssembly framework, hits 1.0
- Extism 1.0.0 Released

WASM by Example
Extism handles this really well across 16 or so different languages - and you don’t need to write a whole IDL / schema.
https://github.com/extism/extism
It’s a general purpose framework for building with WebAssembly and sharing code across languages is a great way to put it to work.
