Today we are thrilled to announce the Release Candidate for Rolldown 1.0. TL;DR: Rolldown is a JavaScript/TypeScript bundler written in Rust. It is 10-30x faster than Rollup while maintaining compatibility with Rollup's plugin API. This RC marks API stability. No breaking changes are planned before 1.0. We encourage you to test it on your projects and report any issues. Using Vite? Try Rolldown to
Back to BlogTuesday, January 20th 2026 Inside Turbopack: Building Faster by Building LessPosted by Edit. Save. Refresh. Wait… Wait… Wait… Compiling code usually means waiting, but Turbopack makes iteration loops fast with caching and incremental computation. Not every modern bundler uses an incremental approach, and that’s with good reason. Incremental computation can introduce significant complex
12/29/2025 Lately, I've been working on porting more of Parcel to Rust. One of the challenges with Rust-based tools is how to support plugins. Many of the most common tools already have Rust-based equivalents: SWC and OXC for JavaScript, Lightning CSS for CSS, oxvg for SVG, etc. But other popular tools like React Compiler, Less, and Sass, are still written in JavaScript, so we need a way to run th
How Rolldown Works: Symbol Linking, CJS/ESM Resolution, and Export Analysis Explained Introduction Rolldown is a high-performance JavaScript bundler written in Rust. While offering full compatibility with the Rollup API, it achieves bundling speeds 10 to 30 times greater. Driven by the need for a single, unified engine for both development and production, the Vite team is developing Rolldown to be
Over the past year (2024) there has been a strong movement to rewrite JavaScript tools in Rust to make them faster. Rust is well suited for this as it runs much closer to hardware and doesn't rely on garbage collection. This makes it an ideal candidate for computationally intensive tasks. Linting in its basic form is such a task, as it involves parsing and traversing lots of source code. But there
We are happy to announce Biome, toolchain of the web. Biome is the official fork of Rome and it will continue to be Rome’s legacy. Biome is led and maintained by the same people that maintained Rome so far. Follow us: Github organization Official repository Official discord server I want to give you some background and context, which could help you to get why the core team created a new project wi
ちょっと時間が経ってしまったのですが Rome の core contributor になったので、なるまでの振り返りと現在の Rome の状況について少し書きたいと思います。 Rome とは Rome は、増え続けている JavaScript の開発に必要なツールチェーンを統一し、開発者体験を改善しようということで始まった OSS です。現在は、JS (JSX)・TS・JSON に対する formatter と linter を提供しています。 Babel の生みの親である Sebastian McKenzie さんが 2017 年頃からプライベートで開発を始め、2020 年頃からは OSS として開発が進められています。2021 年の 7 月ごろまでは、3rd party の npm パッケージを極力利用せずに TypeScript で実装されていました。[1] 2021 年の 7 月
We are thrilled to announce Rome v10, the first stable release since the start of the Rust rewrite. Rome is an ambitious project aiming to unify the dozens of frontend language tools into a single easy-to-use tool built from scratch. This release includes our fast linter and formatter; they require minimal configuration, come with beautiful and descriptive diagnostics, and have built-in support fo
Rome started off written in JavaScript because that is the language of choice for our team and it made it easier for others in the community to join as contributors. We love JavaScript and TypeScript (and HTML and CSS) at Rome, and we want to build the very best tooling possible for these languages. For a number of reasons, we’ve decided that Rust will provide a better foundation for this tooling.

Dec 4, 2018 So I’ve decided to have a go at building a JS interpreter in Rust. I’ve wanted to do this for a while for a couple of reasons: Learn Rust Learn more about how JS implementations work Learn more about the JS specification There isn’t a fully fledged compiler in Rust yet for JS It’s fun! The interpreter itself is called Boa and you can join me on every step of the way on this too. First
We are pleased to announce the first release of the web-sys crate! It provides raw bindings to all the Web’s APIs: everything from DOM manipulation to WebGL to Web Audio to timers to fetch and more! Almost three months ago, we laid out our vision for wasm-bindgen: We are building a shared foundation for an ecosystem of Rust crates that target JavaScript environments with wasm-bindgen. Sharing a fo
As Lin Clark emphasizes in her article about Rust and WebAssembly: the goal of WebAssembly is not to replace JavaScript, but to be an awesome tool to use with JavaScript. Lots of amazing work has been done to simplify crossing the language boundary between JavaScript and WebAssembly, and you can read all about that in Alex Crichton’s post on wasm-bindgen. This post focuses on a different type of J
概要 WebAssemblyを使ってJavaScriptからRustの関数を使うときの話 JavaScript<->Rustのデータのやり取りをする方法をまとめました。 数値、String、Arrayで書き方が違うみたいです。 github.com 参考にしたページ https://sbfl.net/blog/2017/03/13/rust-wasm/ 全体的なWebAssemblyの動かし方について参考にさせていただきました。 http://stackoverflow.com/questions/24145823/rust-ffi-c-string-handling Stringの受け渡しについて参考にさせていただきました。 http://qiita.com/shizu-oka/items/d386001b45f5cd2aacab Arrayの受け渡しについて参考にさせていただきました。
もう結構前になりますが、Rust で Emscripten を利用することなく WebAssembly の出力ができるようになりました。それにより、Rust を使った WebAssembly の開発が現実的な選択肢としてさらに力を帯びてきました。 自分の勉強で Rust から WebAssembly に出力するプログラムを書いてみたので、その道筋をご紹介することで自分のような Rust 初心者の方々の WebAssembly 開発の助けになればと思い、この記事を投稿しました。 もし記事中に間違い等がありましたら、是非 @tkihira までご連絡ください。 Emscripten との依存関係を切った Rust つい最近まで、WebAssembly の出力は Emscripten を使うことがほとんどでした。Emscripten は、元々は他言語のプログラムを JavaScript に変換す
