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.

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.)
- Is it possible to read a file through webassembly?

Extending web applications with WebAssembly and Python
The webassembly-language-runtimes is focused on providing WASI-based language interpreters, what would require a WASI polyfill at the browser level (https://wasi.dev/polyfill/) and (https://github.com/bjorn3/browser_wasi_shim).
Pyodide is certainly another option, but is emscripten based, not based in webassembly-language-runtimes or WASI.

The Tug-of-War over Server-Side WebAssembly
Indeed, some people are doing this:
- WASI once had an official polyfill https://wasi.dev/polyfill/, now apparently succeeded by https://github.com/bjorn3/browser_wasi_shim
- wasmer-js provides a JS polyfill for WASI https://docs.wasmer.io/integrations/js/wasi
- Cloudflare has a WIP polyfill https://github.com/cloudflare/workers-wasi
I'm generally leery of non-temporary polyfills, so I'm not sure that any of these feel like a long-term viable option for me.

WASI Support in Go
The answer is: it's complicated. Which is most of the time the answer in the WASI world.
For this case it's complicated because some runtime supports https://github.com/WebAssembly/threads which mostly contains things like the spec for atomic but not the actual "threads" specs and then some runtimes (i.e wasmtime) also supports https://github.com/WebAssembly/wasi-threads which is one version of the threads. But a new proposal came into play https://github.com/abrown/thread-spawn so ... it's complicated.
