history

Project history and usage

markdownlint-cli2 is David Anson's newer command-line wrapper around the Node.js markdownlint library, intended for fast, configuration-centered linting of Markdown and CommonMark files.

Project history

The GitHub repository was created on 2020-07-03, shortly before the npm package appeared on 2020-07-04. Its README presents it as a replacement-style companion to markdownlint-cli: it is configuration-based, prioritizes speed, and keeps compatibility with markdownlint rules while changing the user workflow around config files and glob handling.

The project sits in the same ecosystem as David Anson's markdownlint library and vscode-markdownlint extension. It exposes the markdownlint engine as a standalone CLI, an npm package, Docker images, and a pre-commit hook target, which made it useful outside editors and CI systems.

Adoption history

By 2026-07-01 the GitHub repository reported 849 stars and 76 forks, and the package was available through npm, Homebrew, Nix, and Arch packaging according to the supplied package-manager facts. The README also documents a GitHub Action and Docker images, reflecting use in repository automation rather than only local editing.

How it is used

Typical use is to run markdownlint-cli2 over Markdown globs, often excluding generated or dependency directories with ignored glob patterns. The tool discovers project config files such as .markdownlint-cli2.jsonc, .markdownlint-cli2.yaml, .markdownlint.* variants, package.json, or pyproject.toml, and also accepts an explicit --config path.

Package maintainers care about it because it is a small but opinionated CLI around an established Markdown linter: it standardizes Markdown style checks for docs-heavy repositories and is easy to wire into npm scripts, pre-commit, Docker, or GitHub Actions.

Why package nerds care

markdownlint-cli2 is a good example of the second-generation CLI pattern around a reusable library: the core lint rules live in markdownlint, while the package-manager-facing tool optimizes installation, config discovery, CI ergonomics, and formatter support.
