yaml-fmt

A configurable YAML formatter for Node.js (CLI & API) that sorts object keys and array values in YAML files. Currently at v0.0.8, with infrequent releases. Key differentiators include support for wildcard targets, property-specific sort configurations, and JSON-based config files. Provides ESM and CJS support, ships TypeScript types, and can be used as a CLI tool via `yaml-fmt fmt` or programmatically. Alternatives like prettier or yq offer broader functionality but less YAML-specific sorting control.
