**Biome** is a performant toolchain for web projects, it aims to provide developer tools to maintain the health of said projects. **Biome is a [fast formatter](./benchmark#formatting)** for _JavaScript_, _TypeScript_, _JSX_, _JSON_, _CSS_ and _GraphQL_ that scores **[97% compatibility with _Prettier_](https://console.algora.io/challenges/prettier)**. **Biome is a [performant linter](https://github.com/biomejs/biome/tree/main/benchmark#linting)** for _JavaScript_, _TypeScript_, _JSX_, _CSS_ and _GraphQL_ that features **[more than 270 rules](https://biomejs.dev/linter/rules/)** from ESLint, typescript-eslint, and [other sources](https://github.com/biomejs/biome/discussions/3). It **outputs detailed and contextualized diagnostics** that help you to improve your code and become a better programmer! **Biome** is designed from the start to be used [interactively within an editor](https://biomejs.dev/guides/integrate-in-editor/). It can format and lint malformed code as you are writing it. ### Installation ```shell npm install --save-dev --save-exact @biomejs/biome ``` ### Usage ```shell # format files npx @biomejs/biome format --write ./src # lint files and apply the safe fixes npx @biomejs/biome lint --write ./src # run format, lint, etc. and apply the safe fixes npx @biomejs/biome check --write ./src # check all files against format, lint, etc. in CI environments npx @biomejs/biome ci ./src ``` If you want to give Biome a run without installing it, use the [online playground](https://biomejs.dev/playground/), compiled to WebAssembly. ## Documentation Check out our [homepage][biomejs] to learn more about Biome, or directly head to the [Getting Started guide][getting-started] to start using Biome. ## More about Biome **Biome** has sane defaults and it doesn't require configuration. **Biome** aims to support [all main languages][language-support] of modern web development. **Biome** [doesn't require Node.js](https://biomejs.dev/guides/manual-installation/) to function. **Biome** has first-class LSP support, with a sophisticated parser that represents the source text in full fidelity and top-notch error recovery. **Biome** unifies functionality that has previously been separate tools. Building upon a shared base allows us to provide a cohesive experience for processing code, displaying errors, parallelize work, caching, and configuration.
