WebAssembly JSPI has a new API · V8
WebAssembly’s JavaScript Promise Integration (JSPI) API has a new API, available in Chrome release M126. We talk about what has changed, how to use it with Emscripten, and what is the roadmap for JSPI. JSPI is an API that allows WebAssembly applications that use sequential APIs to access Web APIs that are asynchronous. Many Web APIs are crafted in terms of JavaScript Promise objects: instead of im
WebAssembly所感
WebAssemblyをちょっといじってみて思ったところをまとめてみます。 設計思想 WebAssembly/designに設計文書がまとまっています。特にHighLevelGoals.mdから読み取れるポイントは以下の4点です。 サンドボックス化された環境であること。 移植性があること。つまり、特定の実CPUアーキテクチャ等に依存しないこと。 少なくともC/C++の(十分に高速な)コンパイルターゲットとして機能すること。 安定した仕様を持つこと。 サンドボックスという観点からは、先行技術として以下のようなものが特筆に値します。 Webサンドボックス JavaScript および asm.js Javaアプレット Flash (ActionScript) NaCl, PNaCl Web以外のサンドボックス OSのユーザーランド、特にLinux userland これらのサンドボックスとの比
MoonBit adds JS backend, up to 25x faster than native JS | MoonBit
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

WasmGCについて予習する
この記事はWebAssembly Advent Calendar 2023 2日目の記事です． ガベージコレクタ(WasmGC)[1]が10月頃にChromeとFirefoxでデフォルトで有効になり，標準化目前ということで大いに盛り上がったのは記憶に新しいかと思います． これはChromeが対応したというよりはChromeが採用しているJavaScriptのランタイムであるV8がデフォルトでWasmGCが有効になったというのが正確な表現で，DenoでもDartからビルドしたWasmを実行する際にGCを有効にするフラグを立てる必要がなくなり，実行しやすくなったなぁと皆さんも感じているかと思います． -$ deno run --allow-read --v8-flags=--experimental-wasm-gc run.js +$ deno run --allow-read run.js
A new way to bring garbage collected programming languages efficiently to WebAssembly · V8
A recent article on WebAssembly Garbage Collection (WasmGC) explains at a high level how the Garbage Collection (GC) proposal aims to better support GC languages in Wasm, which is very important given their popularity. In this article, we will get into the technical details of how GC languages such as Java, Kotlin, Dart, Python, and C# can be ported to Wasm. There are in fact two main approaches:
WebAssembly Garbage Collection (WasmGC) now enabled by default in Chrome - Chrome for Developers
WebAssembly Garbage Collection (WasmGC) now enabled by default in Chrome Published on Tuesday, October 31, 2023 There are two types of programming languages: garbage-collected programming languages and programming languages that require manual memory management. Examples of the former, among many more, are Kotlin, PHP, or Java. Examples of the latter are C, C++, or Rust. As a general rule, higher-

Audjust - Snappy UIs With WebAssembly and Web Workers
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

The State of WebAssembly – 2022 and 2023
In this article, I will look at the current state of WebAssembly (wasm). I’ll start by revisiting 2022 developments to see if any of my predictions came true and if there were any surprises. Then I’ll try to predict where I think things will go in 2023. In 2021, Safari surprised me with how much work went into catching up to the other browsers’ WebAssembly support. So how did Safari do over the pa

Performance of WebAssembly runtimes in 2023 | Frank DENIS random thoughts.
Using libsodium in a web browser has been possible since 2013, thanks to the excellent Emscripten project. Since then, WebAssembly was introduced. A more efficient way to run code not originally written in JavaScript in a web browser. And libsodium added first-class support for WebAssembly in 2017. On web browsers supporting it, and in allowed contexts allowing it, that gave a nice speed boost. Li
Wasmはなぜセキュアなのか？
