Use Cases & Benefits
- Marked is a fast, lightweight JavaScript markdown parser and compiler supporting CommonMark and GitHub Flavored Markdown.
- It works in browsers, Node.js (current and LTS versions), and via CLI, enabling versatile markdown processing environments.
- Marked does not sanitize HTML output, so users must apply external sanitization libraries like DOMPurify for security.
- Organizations can integrate Marked for real-time markdown rendering in web apps, static site generation, or CLI markdown processing.
- Ideal use cases include markdown previewers, documentation sites, static site generators, and any app requiring fast markdown parsing.
