Remarklint

remarklint is an open-source linter for Markdown built to work within the remark ecosystem of the unified.js project. It analyzes Markdown documents to detect issues related to syntax, structure, and style, according to a configurable set of linting rules. The goal is to help teams maintain consistent, readable documentation across a codebase.

Remarklint operates as part of the Node.js tooling used with the remark parser and its plugins. It can be run as a command-line tool or integrated into scripts and continuous integration workflows. Users can enable, disable, or customize rules via configuration files or package.json entries, and they can apply presets that group multiple rules.

The tool is maintained by the open-source community and is commonly used in JavaScript and Markdown-heavy projects. It is compatible with other remark plugins and can be extended with additional rule packages. Typical workflows involve running the linter during development and in CI to catch formatting and style issues early, with the option to automatically fix certain problems.

Output from the linter consists of warnings and errors with location information, helping writers and maintainers identify and correct issues. Overall, remarklint provides a standardized approach to Markdown quality, aligning with the broader remark and Unified tooling for document processing.
