Why Use JS Style Kit?

JS Style Kit eliminates the need to manage dozens of ESLint and Prettier plugins and configurations. It provides a comprehensive, zero-configuration solution with sensible defaults that work well for most projects. At the same time, it offers flexible configuration options for teams with specific needs.

​
Key benefits:

  • Zero configuration - Works out of the box with smart defaults

  • Modern practices - Uses the latest ESLint flat config format and modern rules
  • Customizable - Sensible defaults with flexible configuration options
  • Production tested - Actively used in real-world projects

​
Project Status

JS Style Kit is currently in beta. The core ESLint and Prettier configurations are stable and well-tested, but the CLI tool is still under development and best suited for new projects.

Requirements

  • Node.js v20.11.0 or higher
  • TypeScript (for TypeScript projects, not bundled)
