Show GN: ESLint Markdown: Lint Your Markdown Files with ESLint

The eslint-markdown package has been released, enabling Markdown files to be linted with ESLint.

Following ESLint's official announcement of Markdown support on October 3, 2024, it was designed to align with that direction and API.

Key features are as follows.

• Provides over 20 rules, which do not overlap with @eslint/markdown, ESLint core's Markdown support package.
• When used together with the core rules, over 40 Markdown-related rules are available.
• Supports CommonMark, GitHub Flavored Markdown (GFM), and Front Matter.
• Provides recommended, stylistic, and base shared configs.

For projects already using ESLint, Markdown quality management can be integrated into the existing configuration workflow. It's a fitting option for teams looking to unify linting of documentation and code into a single tooling system.

In the long run, it aims toward a flow where more file formats are linted together with a single ESLint, targeting a position that complements or partially replaces existing tools like markdownlint and remark-lint.

Going forward, there are plans to add a wider variety of rules, including style rules.
