Biome and the Future of JavaScript Tooling

Modern web development requires an ever-growing collection of tools including formatters, linters, bundlers, and plugins. Each tool typically has its own configuration, dependencies, and performance cost. As applications grow more complex, the overhead of maintaining this toolchain becomes a real burden. 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. Emanuele Stoppa, known as Ema, is a Senior Systems Engineer at Cloudflare, a lead at Astro, and the creator and lead maintainer of Biome. In this episode, Ema joins Josh Goldberg to discuss the history of Biome, how linters and formatters work under the hood, what makes Biome’s architecture fundamentally different from the tools it replaces, and what’s coming next for the project and its community. Josh Goldberg is an independent full time open source developer in the TypeScript ecosystem. He works on projects that help developers write better TypeScript more easily, most notably on typescript-eslint: the tooling that enables ESLint and Prettier to run on TypeScript code. Josh regularly contributes to open source projects in the ecosystem such as ESLint and TypeScript. Josh is a Microsoft MVP for developer technologies and the author of the acclaimed Learning TypeScript (O’Reilly), a cherished resource for any developer seeking to learn TypeScript without any prior experience outside of JavaScript. Josh regularly presents talks and workshops at bootcamps, conferences, and meetups to share knowledge on TypeScript, static analysis, open source, and general frontend and web development.   Please click here to see the transcript of this episode.
