Built with Rust, it offers 35x faster performance than Prettier and features type-aware linting without requiring the TypeScript compiler. Key improvements include multi-file analysis, customizable plugins, enhanced monorepo support, simplified configuration through a single biome.json file, and automated migration tools from ESLint and Prettier. ## Content Biome v2 marks a significant advancement in JavaScript and TypeScript tooling, positioning itself as a formidable alternative to traditional solutions like ESLint and Prettier. Emerging from the former Rome project, Biome v2 introduces groundbreaking type-aware linting without the need for the TypeScript compiler, enabled by a lightweight type inference engine. One of the standout features of Biome v2 is its comprehensive support for multi-file analysis, allowing developers to gain insights across their entire project. The toolchain also emphasizes performance optimization, claiming to be 35 times faster than Prettier, thanks to its Rust-based architecture. With the introduction of customizable linting plugins, including support for technologies like GritQL, Biome v2 offers enhanced flexibility and extensibility. The release also features improved monorepo support with nested configurations, a revamped import organizer, and new assist actions. Biome v2 further simplifies project setup through a single `biome.json` configuration file, streamlining the process compared to the complex plugin configurations typically required by ESLint and Prettier. Additional features include Tailwind CSS class sorting and an HTML formatter that is currently experimental. For those looking to transition from existing tools, Biome provides automated migration tools to ensure backward compatibility, alongside guides for users migrating from ESLint and Prettier. Despite some feature gaps, such as limited HTML template support for frameworks like Svelte and Astro, Biome v2 is establishing itself as a robust and efficient all-in-one solution for modern JavaScript and TypeScript development. ## Similar posts on daily.dev - [Don’t just attend KubeCon \+ CloudNativeCon, Merge Forward your experience\!](https://daily.dev/posts/don-t-just-attend-kubecon-cloudnativecon-merge-forward-your-experience--l0rpp73x8) · CNCF · 1 upvotes · 0 comments - [Announcing H2 2026 KCDs](https://daily.dev/posts/announcing-h2-2026-kcds-m96goajm1) · CNCF · 1 upvotes · 0 comments - [Two months of Open Community Groups](https://daily.dev/posts/two-months-of-open-community-groups-asf52zhbs) · CNCF · 0 upvotes · 0 comments - [CNCF Unveils Schedule for KubeCon \+ CloudNativeCon Europe 2026](https://daily.dev/posts/cncf-unveils-schedule-for-kubecon-cloudnativecon-europe-2026-ikhcoa5cb) · CNCF · 2 upvotes · 0 comments - [CNCF Debuts KubeCon \+ CloudNativeCon Japan 2026 Schedule](https://daily.dev/posts/cncf-debuts-kubecon-cloudnativecon-japan-2026-schedule-xp5pyudub) · CNCF · 1 upvotes · 0 comments --- Tags: [#javascript](https://daily.dev/tags/javascript), [#rust](https://daily.dev/tags/rust) [View this post on daily.dev](https://daily.dev/posts/introducing-biome-v2-0-beta-a-faster-and-unified-javascript-toolchain-vloxesvse) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Introducing Biome v2.0 Beta: A Faster and Unified JavaScript Toolchain","url":"https://daily.dev/posts/introducing-biome-v2-0-beta-a-faster-and-unified-javascript-toolchain-vloxesvse","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/introducing-biome-v2-0-beta-a-faster-and-unified-javascript-toolchain-vloxesvse"},"datePublished":"2025-06-17T09:47:23.753Z","dateModified":"2025-06-19T20:52:46.215Z","description":"Biome v2 is a high-performance JavaScript and TypeScript toolchain that combines linting and formatting capabilities in a single tool.
