validate-links

To validate markdown links, run the validator on your MDX/Markdown files to automatically check internal paths, external HTTP(S) availability, and anchor existence across single or multiple files.

Yes, you can integrate anchor validation into pre-commit hooks to confirm anchors exist in target headings and current files before release, preventing broken navigation in your MDX documentation.

Yes, external URL checks optionally verify HTTP and HTTPS availability and redirects, ensuring navigability and accuracy for outbound references in your documentation sets.

The best way to fix broken internal documentation links is using the auto-fix feature, which automatically corrects relative or absolute path formatting for your internal references.

You can check links across multiple markdown files in CI/CD by running the validator with glob patterns like docs/**/*.mdx to enforce internal path correctness and HTTP(S) availability automatically.

Internal documentation links break after restructuring because internal docs paths no longer exist or are incorrectly referenced, which validation catches by enforcing internal path correctness.
