eslint-plugin-matrix-org

library3.0.0jsnpmunverified

ESLint plugin providing shareable configs and custom rules used by Matrix.org projects. Current stable version is 3.0.0. It codifies the code style from element-web and offers configs for JavaScript, TypeScript, Babel, React, and Jest. The plugin deliberately has zero runtime dependencies to avoid version conflicts; users must install peer dependencies manually. Key differentiator: it bundles multiple configs (Google, Prettier, unicorn, etc.) into a cohesive set aligned with Matrix.org's style guide.
