eslint-config-xo-react

ESLint shareable config for React projects, designed to be used with eslint-config-xo. Current stable version is 0.30.1, released in early 2025. This package enforces a strict, opinionated set of React and JSX rules including hooks, prop types, accessibility, and security. It supports both React and Preact, and requires Node.js >=18.18 and ESLint >=9.18.0. Unlike generic React ESLint configs, it integrates tightly with the XO style guide and provides options for spaces vs tabs in JSX. Ships TypeScript types, but is ESLint 9 (flat config) only from v0.30.0.
