A tiny WASM compiler and runtime for demonstration purposes
Hello, I'm building a WebAssembly compiler and documenting the process in the meantime. This aims to be a tool for demonstration and education purpose. It doesn't aim to do fancy stuff nor to replace existing ones. I'm building this to learn and to improve and hopefully it can be useful for others as well :) From last time I've presented the idea, I've implemented more basic features on Luna and I've built a custom and tiny runtime for Luna! (documenting it of course). Any feedback is really appreciated :) Repo: https://github.com/thomscoder/luna

In plain words
Luna is a minimal WebAssembly compiler and runtime designed for learning and demonstration purposes. It includes basic compilation features and a custom lightweight runtime, with documentation throughout the development process. The tool is intended for developers and students seeking to understand how WebAssembly compilers work, rather than as a production-ready replacement for existing solutions. The project prioritizes educational value and incremental improvement.

Wrote a tiny WebAssembly (wat2wasm) compiler in Go2022 · github.com · ▲75As a personal project I wrote a really tiny Wat 2 Wasm compiler in Go. Mainly for demonstrative and educational purposes. It was tough: I didn't know anything about WebAssembly internals and I'm a newbie with Go... so I tried to document it as much as I could for anyone that would like to approach the quest in the future! It misses a lot of features (that will be gradually implemented). Any feedback is welcomed!! Demo: https://luna-demo.vercel.app

Jaws – a JavaScript to WASM ahead-of-time compiler2024 · github.com · ▲290I've open sourced a JavaScript to WASM compiler. It's an experimental tool, but given the semantics I already implemented, I'm fairly certain I am able to eventually cover 100% of JavaScript spec. Any ideas, questions or critique welcomed! If you are interested in WASM, especially with new proposals like WASM GC or exception handling, it might be a good source of seeing these features in action - the project has a few thousand lines of hand written WAT so far.

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…

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
