markdown-it is a fast, pluggable Markdown parser for JavaScript with 100% CommonMark support plus syntax extensions like URL autolinking and typographer. Its configurable rule system allows adding or replacing syntax rules, and it has a large ecosystem of community plugins.
Use cases
- render markdown to html in node.js
- parse markdown in the browser
- convert markdown files to html
- add custom markdown syntax extensions
- build a blog or cms with markdown content
- sanitize untrusted markdown input safely
When to choose
- you need spec-compliant CommonMark rendering
- you want to extend or customize markdown syntax with plugins
- parsing speed matters
- you need safe-by-default rendering of user-supplied markdown
When to avoid
- you need markdown flavors like GFM tables out of the box without plugins
- you are not working in JavaScript/TypeScript
- you need a WYSIWYG markdown editor rather than a parser
