I started this project while working on a stress testing tool called Crows that runs WebAssembly scenarios. At the moment it only supports code compiled from Rust to WASM. As much as I love writing Rust, I also know it's not a widely popular language and besides, small tests are often easier to write in interpreted languages. The problem is, running scripting languages on top of WASM is not ideal
An ahead-of-time JavaScript compiler Porffor compiles JavaScript ahead-of-time to WebAssembly and native binaries. It is currently in pre-alpha with usability beginning in 2025. JS -> Wasm Porffor's WebAssembly output is 10-30x smaller and faster compared to existing JS -> Wasm projects as Porffor compiles JS instead of bundling an interpreter in the Wasm output. JS as Wasm allows for sandboxed ex
When MoonBit officially launched in August 2023, our critical mission was unleashing the potential of WebAssembly in cloud and edge computing as a Wasm-first programming language and toolchain. By integrating the essence of Rust and Go, MoonBit has not only achieved simplicity and usability in design but also been equipped with a robust fault-tolerant type system. At the same time, MoonBit is work

Published: 2023-08-07 Our web app allows users can change the length of a song or find loops present in it for infinite listening, remixing, or for their next next video edit or performance. After uploading a song, there is an initial server-side analysis step after which the audio can be manipulated completely in the browser. Users can alter the desired length or mark sections of audio to prefer

We’re happy to announce the inclusion of Javy as a hosted project under the Bytecode Alliance. This post will delve into what Javy is, the motivation behind its adoption, and the process that led to its integration into the Bytecode Alliance. Javy Javy is a JavaScript-to-WebAssembly toolchain originally developed by Shopify to bring JavaScript support to Shopify Functions. It is based on the Quick
Bringing Javascript to WebAssembly for Shopify Functions - Shopify
Bringing Javascript to WebAssembly for Shopify FunctionsWhile we’re working on getting our Shopify Functions infrastructure ready for the public beta, we thought we’d use this opportunity to shine some light on how we brought JavaScript to WebAssembly, how we made everything fit within our very tight Shopify Function constraints, and what our plans for the future look like. At Winter Editions 2023
はじめに 引き続き Rust + WebAssembly + SolidJS で遊んでいます。前回は、Rust 側で作成した文字列を JavaScript 側で console.log に出力することを考えましたが、今回は JavaScript 側から何らかのデータを Rust 側へ渡すことを考えたいと思います。今回も、wasm-bindgen[1] に頼らずにやっていきましょう。 メモリの確保と管理 WebAssembly のメモリ空間は、シンプルな Linear Memory（線形メモリ）になっています。Rust と JavaScript との間で、「プリミティブな数値型」より大きなデータをやりとりするためには、この Linear Memory 上にデータを配置するのが良さそうです[2]。 単一のメモリバッファの確保 メモリの確保は Rust 側で実施します。線形メモリ上には WebA
WebAssembly, a.k.a. WASM, is a standard defining a low-level programming language suitable (A) as a target for cross-compilation from many other languages and (B) for running via a virtual machine in a browser. Designed with scriptability via JavaScript in mind, it provides a way to compile C code (among others) to WASM and script it via JavaScript with relatively little friction despite the vast
You should be able to import this directly into Node, as normal, or in a browser using any bundler that supports ES modules & webassembly (e.g. Webpack v4 or v5, Vite, Rollup, and most others). For each target (node.js, commonjs bundlers & ESM bundlers) this module exports a different WASM file & setup, with a slightly different entrypoint. These entrypoints all expose a consistent default-export
