**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](https://github.com/biomejs/benchmark#formatting)** for _JavaScript_, _TypeScript_, _JSX_, _JSON_, _CSS_, _GraphQL_, _Markdown_, _YAML_, and _SCSS_ that scores **[97% compatibility with _Prettier_](https://algora.io/challenges/prettier)**.

**Biome is a [performant linter](https://github.com/biomejs/benchmark#linting)** for _JavaScript_, _TypeScript_, _JSX_, _JSON_, _CSS_, _GraphQL_, _Markdown_, _YAML_, and _SCSS_ that features **[more than 500 rules](https://biomejs.dev/linter/javascript/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/editors/first-party-extensions/).
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

# lint files and apply the safe fixes
npx @biomejs/biome lint --write

# run format, lint, etc. and apply the safe fixes
npx @biomejs/biome check --write

# check all files against format, lint, etc. in CI environments
npx @biomejs/biome ci
```
