micromark is a small, safe, 100% CommonMark-compliant markdown parser written in JavaScript, implemented as a state machine that emits concrete tokens with positional info and compiles them to HTML. It supports extensions such as GFM, MDX, directives, frontmatter, and math, and serves as the parsing foundation of the unified/remark ecosystem.

Use cases

• convert markdown to html in javascript
• parse markdown with a commonmark compliant parser
• add github flavored markdown support to my app
• build a custom markdown extension or syntax plugin
• get token positions from markdown source
• render mdx content safely
• build an ast from markdown for further processing

When to choose

• you need strict CommonMark (or GFM/MDX) compliance with high safety guarantees
• you want the smallest footprint markdown parser (~14kb)
• you need concrete tokens and positional info for complex markdown tooling
• you are building on the unified/remark ecosystem

When to avoid

• you need a ready-made AST rather than concrete tokens (use remark/mdast instead)
• you need markdown parsing in a non-JavaScript language
• you want a batteries-included markdown editor or renderer with UI
