This is an ESLint plugin that provides three formatting rules (`format/prettier`, `format/dprint`, `format/oxfmt`) to format code using Prettier, dprint, and oxfmt respectively. It is designed to be used with ESLint's flat config and treats formatters as side-effects-free tools, giving users full control over which formatter to apply to which file types. The plugin uses `synckit` to run formatters synchronously in worker threads, and `eslint-formatting-reporter` to generate fix suggestions. The architecture is clean: each rule is a standard ESLint rule that lazily loads a synchronous wrapper around the actual formatter library. The codebase is well-structured, with comprehensive tests and CI. It is actively maintained and uses modern JavaScript/TypeScript practices.
