markdownlint

A Node.js style checker and lint tool for Markdown/CommonMark files. Current stable version is 0.40.0, released with a history of regular updates. It uses the micromark parser and honors the CommonMark specification, also supporting GFM syntax like autolinks and tables, as well as directives, footnotes, and math via micromark extensions. Unlike other Markdown linters, it provides a comprehensive library of rules and is designed for programmatic use in Node.js projects, with multiple CLI wrappers and editor integrations.
