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.

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:

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 donโt need to write a whole IDL / schema.
https://github.com/extism/extism
Itโs a general purpose framework for building with WebAssembly and sharing code across languages is a great way to put it to work.

- another 4x to 5x speed up in calling #WASM #WebAssembly from python is on the horizon

WebAssembly: Adding Python Support to WASM Language Runtimes
Wasmtime's `wasmtime-py` embedding in python has support for Wasm Components: https://github.com/bytecodealliance/wasmtime-py#components (disclosure, I helped create it)
The remaining piece of the puzzle would be to create a wit-bindgen guest generator https://github.com/bytecodealliance/wit-bindgen#guests for this build of the python interpreter. You could then seamlessly call back and forth between the host and guest pythons, without even knowing that wasmtime is under the hood.
What are some alternatives?
wit-bindgen - A language binding generator for WebAssembly interface types
nsjail - A lightweight process isolation tool that utilizes Linux namespaces, cgroups, rlimits and seccomp-bpf syscall filters, leveraging the Kafel BPF language for enhanced security.
WASI - WebAssembly System Interface
python-wasi - Utilities for building CPython for the WASI platform
wasmtime - A fast and secure runtime for WebAssembly
pywasm3 - Python bindings for Wasm3, a fast WebAssembly interpreter and the most universal WASM runtime
wasmer - ๐ The leading Wasm Runtime supporting WASIX, WASI and Emscripten
empack - Tools to pack a conda / mamba environment into a JS & WASM bundle
jssc - Java library for talking to serial ports (with added build support for maven, cmake, MSVC)
python-sandbox-wasm
nodejs-snowflake - Generate time sortable 64 bits unique ids for distributed systems (inspired from twitter snowflake)
wasmer-python - ๐๐ธ WebAssembly runtime for Python
