Biome

This is the Rust-based replacement for ESLint and Prettier that claims 100x speed improvements, and the configuration shows it's actually serious about being a drop-in replacement. You get linting and formatting in one tool with zero-config defaults, though the real win is for TypeScript projects where the native speed makes a difference in large codebases. The migration commands from Prettier and ESLint configs are included, and there's proper VS Code integration with format-on-save. Worth trying if you're tired of juggling two tools and waiting for ESLint to crawl through your monorepo, though you'll want to verify rule parity if you have a heavily customized ESLint setup.

Biome - Fast All-in-One Toolchain

Overview

Biome is a fast, all-in-one toolchain for web projects written in Rust. It replaces both ESLint and Prettier with a single tool that's 100x faster and provides zero-config defaults.

Key Features:

Single tool for linting and formatting
100x faster than ESLint
Zero configuration by default
Built-in import sorting
TypeScript-first design
Partial Prettier compatibility
Native monorepo support
VS Code integration

Installation:

npm install --save-dev @biomejs/biome

Quick Start

1. Initialize Biome

# Create biome.json configuration
npx @biomejs/biome init

# Check your project
npx @biomejs/biome check .

# Fix issues automatically
npx @biomejs/biome check --write .

# Format only
npx @biomejs/biome format --write .

# Lint only
npx @biomejs/biome lint .

2. Package.json Scripts

{
  "scripts": {
    "check": "biome check .",
    "check:write": "biome check --write .",
    "format": "biome format --write .",
    "lint": "biome lint .",
    "lint:fix": "biome lint --write ."
  }
}
