JS tool: Biome, vs Prettier, Eslint

 Try Biome. An alternative to Prettier and Eslint | by Jose Garcia | Medium

Biome, a modern, Rust-based tool designed to replace both Prettier (for formatting) and ESLint (for linting) in JavaScript and TypeScript workflows.

Key Highlights

• Prettier Compatibility: Biome boasts 97% compatibility with Prettier, making it highly straightforward to migrate existing projects without losing your established styling.

• Blazing Speed: Built on Rust, Biome claims to run roughly 35 times faster than Prettier, significantly cutting down execution times for large codebases.

• Simplified Configuration: Instead of managing multiple conflicting packages (eslint, prettier, eslint-config-prettier, etc.) and separate configuration files, Biome collapses everything into a single dependency (@biomejs/biome) and a single biome.json file.

• The Trade-offs: Because it is younger and less established than ESLint and Prettier, Biome is slightly less stable, supports fewer third-party ecosystem tools, and can be harder for open-source contributors to develop due to being written in Rust.

Biome and the Future of JavaScript Tooling - Software Engineering Daily

Biome is an open source toolchain for web projects that brings formatting and linting together in a single fast, opinionated tool. It’s built in Rust and is designed to be a drop-in replacement for Prettier and ESLint, with sensible defaults, minimal configuration, and consistent behavior across the CLI and editor environments. Biome also introduces a module graph that enables cross-file analysis, and type-aware lint rules that don’t require the TypeScript compiler.
