library2.0.0jsnpmunverified

A meta-formatter for ESLint that runs multiple output formatters (e.g., stylish to console and checkstyle to file) in a single pass. Version 2.0.0 uses an async API and is ESM-only. Provides a configuration-driven approach via package.json or config file, allowing flexible output paths and console logging. Unlike alternatives that only write to disk, this supports console output and custom formatter names.
