In plain words
TinyWasm is a WebAssembly runtime interpreter written in Rust that executes WebAssembly code. It passes all official WebAssembly 1.0 tests and includes features from future proposals like bulk memory operations. Designed for simplicity and portability, it has minimal dependencies, a small codebase, and works in no_std environments. The tool is intended for developers who want to embed WebAssembly execution into other projects or study interpreter design.

Show HN: TinyWasm - A tiny WebAssembly Runtime written in Rust Hi HN! I'm excited to share TinyWasm (https://github.com/explodingcamera/tinywasm), a WebAssembly Interpreter I developed for my final university project. The main goal of this project was to deepen my understanding of WebAssembly and interpreter design. TinyWasm successfully passes all the official WebAssembly 1.0 tests and also includes features from future proposals such as like bulk memory operations. Initially more of a research project, TinyWasm focuses on simplicity and portability. It has minimal third-party dependencies, a small codebase, and is compatible with no_std environments. It's now available as a standalone library (https://crates.io/crates/tinywasm), and I hope it can be useful for embedding into other projects and hacking on, especially because it's designed to be easy to understand and modify, while still being decently performant. I'm looking forward to feedback, hope you find it useful!

This is the entire Firefox browser rendering to a element. Gecko, all UI components, and the Spidermonkey JS engine are all compiled and running in WebAssembly. Here are a few things you might find interesting: - This is fully end to end encrypted! We use the WISP protocol for TCP-over-websockets. - There is a novel WASM->JS JIT for experimental site speedup - This port cost over 25k in opus/fable tokens for debugging and JIT research This was just a fun experiment to push the boundaries of WebAssembly. For a more usable "browser in browser" experience, we also built…

Raw performance (the lack of) is always a contentious point for JavaScript, especially in our post-Moore era of computing. Node.js gets around this issue through extensive of use of native libraries and modules written in C, including the V8 JS engine itself. But as application developers, how do YOU create high performance functions? Write in C and run as a NAPI module? Write in Rust and run as a V8 wasm? Well, there is another (better and faster) way now! The SSVM is a fully featured WebAssembly VM that is optimized for server-side applications.…
