Hey HN! I've been working on a book about WebAssembly over the last few months, and it's finally available at http://levelupwasm.com! Why a book on WebAssembly you ask? Well... WebAssembly is awesome (obviously ) but it's certainly not the easiest thing to learn. So I wrote this book as a practical intro to using WebAssembly in your web apps. I would appreciate any feedback!

As 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

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…

Hi HN! I’m Syrus, from the Wasmer team. We just released the new version of WAPM that is an order of magnitude better than the previous one (that we also announced here in HN two years ago! [0]), enabling an incredible experience for using and publishing WebAssembly packages. The tech stack that we are using includes: * Python and Django (for the backend) with Graphene (for the open GraphQL API [1]) and Django Channels with websockets over GraphQL [2] for subscriptions * Next.js [3] with React-Relay [4] and Tailwind.css [5] for the frontend * WebAssembly and Wasmer [6] (for the online shell)…

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…

A month or so ago, I ported a Common Lisp implementation (npt) to WebAssembly to make a silly blog post, because I was bored and have a lot of time on my hands to waste with things like this (I don't have a job, and because I have next to no experience, these meaningless, silly projects tend to fill what time I do have). This is significant as it's the first time Common Lisp in particular has ever been hosted on it; wasm has a few poor decisions in its design that make it less-than-conducive to being a target for Common Lisp, and a lot of the more interesting implementations require an…
