GitHub - ohmjs/ohm: A library and language for building parsers, interpreters, compilers, etc.
Ohm is a parsing toolkit consisting of a library and a domain-specific language. You can use it to parse custom file formats or quickly build parsers, interpreters, and compilers for programming languages. The Ohm language is based on parsing expression grammars (PEGs), which are a formal way of describing syntax, similar to regular expressions and context-free grammars. The Ohm library provides a

Prettier 3.8: Support for Angular v21.1 · Prettier
We're excited to announce that Prettier now fully supports the fresh features landing in Angular v21.1 (released today 🎉)! This update brings cleaner, more expressive templates with: Consecutive @case statements in @switch blocks. Spread elements (...) in array literals, object literals, and function calls inside templates. We've also added the ability to format Angular syntax beautifully inside
Introducing: React Best Practices - Vercel
We've encapsulated 10+ years of React and Next.js optimization knowledge into react-best-practices, a structured repository optimized for AI agents and LLMs. React performance work is usually, well, reactive. A release goes out, the app feels slower, and the team starts chasing symptoms. That’s expensive, and it’s easy to optimize the wrong thing. We’ve seen the same root causes across production
Streaming JSON in just 200 lines of JavaScript
I was continueing my exploration of React server components when I stumbled upon on this article about progressive JSON. Dan Abramov describes a technique for streaming JSON from a server to a client in chunks, allowing the client to start rendering parts of the data before the entire payload has been received. This can significantly improve perceived performance, especially for large datasets. So
How to compile JavaScript to C with Static Hermes
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
2025 JavaScript Rising Stars
Welcome to the 10th edition of JavaScript Rising Stars! What a year it has been! From the explosion of AI agents transforming how we build applications to critical vulnerabilities and security attacks that shook the ecosystem, 2025 has been a year of both remarkable innovation and sobering challenges. The following graphs compare the number of stars added on GitHub over the last 12 months. We anal
The many, many, many JavaScript runtimes of the last decade
This last decade has seen an inundation of new JavaScript runtimes (and engines in equal measure), enabling us to run JavaScript in all manner of contexts with precise fitness for task. Through these, we've seen the language spread to the Cloud, the edge, Smart TVs, mobile devices, and even microcontrollers. In this article, we'll explore what's driving this diversity, and why no one runtime or en
第三者のJavaScriptをセキュアに実行するには？― exaBase Studio のプラグイン機能
メリークリスマス🎄 Studio Application 開発グループの吉田です。 エクサウィザーズのAdvent Calendar 25日目、最終日です！ exaBase Studio に Figma みたいなプラグイン機能を入れたい これはけっこう前からずっと頭の片隅にあったアイデアでした。 exaBase Studio（エクサベース スタジオ）はアプリケーション開発基盤ですが、Figma のようなキャンバス画面を持っています。キャンバスを読み書きできるプラグインをユーザー自身が自由に開発できれば、Studioの機能を拡張することができます。 exaBase Studio とは exaBase Studio は、エクサウィザーズが提供するクラウドネイティブな AI サービス開発環境です。GUI でシステム設計ができ、ワンクリックで Kubernetes ベースの本番環境を自動構築でき
