eslint-plugin-yaml

An ESLint plugin that provides linting for YAML files (`.yaml`, `.yml`). Current stable version is 1.1.3, released March 2025. It uses an ESLint-based YAML parser (not js-yaml) since v1.1.0, enabling integration with ESLint's rule system. Supports both ESLint 9 flat config (ESM/CJS) and legacy ESLint 8 configs. Ships TypeScript types. Differentiators: first-class ESLint compatibility with YAML-specific rules, support for multiple YAML documents, and active maintenance with recent dependency updates.
