Biome Toolchain

Biome is an all-in-one toolchain for web projects created by Emanuele Stoppa and the Biome team in 2023, formerly known as Rome, originally created by Sebastian McKenzie, the creator of Babel, in 2020, providing fast formatting, linting, import sorting, and type checking through a single tool written in Rust, designed as a drop-in replacement for ESLint, Prettier, and other individual tools, achieving performance up to thirty times faster than Prettier and ESLint through native Rust execution and parallel processing, adopted by over fifty thousand projects and recommended by the Vue.js and SolidJS teams. The formatter provides opinionated code formatting for JavaScript, TypeScript, JSX, TSX, JSON, and CSS, with the formatting rules derived from Prettier for familiarity, ensuring that code migrated from Prettier requires minimal changes, while the Rust implementation provides significantly faster formatting times, enabling format-on-save in large projects without noticeable delay and efficient CI checks through format verification commands. The linter provides static analysis with over two hundred rules organized by category including correctness, suspicious code, complexity, performance, security, style, and nursery rules, with rules covering common issues including unused imports, unreachable code, invalid hooks, missing dependencies in React hooks, deprecated APIs, security vulnerabilities including prototype pollution and regular expression denial of service, and code style issues, with auto-fix capabilities that automatically correct issues for over half of all rules. The import sorting organizes import statements alphabetically and by group including external, internal, and relative imports, replacing the need for eslint-plugin-import or prettier-plugin-organize-imports. The single binary requires no Node.js or npm dependencies. The editor integration through LSP. Designed for JavaScript and TypeScript developers.
