remark is a markdown processor built on micromark powered by plugins part of the unified collective.

Intro

remark is the world’s most popular markdown parser! And it does so much more than parse: it inspects (check, lint) and transforms (generate, compile) markdown too!

Everything is possible with plugins, such as checking markdown code style (remark-lint), transforming safely to React (remark-react), adding a table of contents (remark-toc), or compiling to man pages (remark-man).

Internally, remark now uses micromark, a new, fast, and tiny CommonMark compliant markdown tokenizer. It can be GFM compliant with remark-gfm.

Finally, remark is part of the unified collective. Learn more about us:

Packages

This repository contains the following packages:

  • remark-parse — Parse markdown to syntax trees
  • remark-stringify — Serialize syntax trees to markdown
  • remark — Programmatic interface with both remark-parse and remark-stringify
  • remark-cli — Command line interface wrapping remark

Security

As markdown is sometimes used for HTML, and improper use of HTML can open you up to a cross-site scripting (XSS) attack, use of remark can also be unsafe. When going to HTML, use remark in combination with the rehype ecosystem, and use rehype-sanitize to make the tree safe.

Use of remark plugins could also open you up to other attacks. Carefully assess each plugin and the risks involved in using them.
