Markdown renderer

FreeLibraries & build toolinggithub.com

What it is

Renders Markdown to React elements, v10, without dangerouslySetInnerHTML. Built on the unified/remark pipeline, so plugins add GitHub-flavoured tables, math or raw HTML, and you can map any element to your own component.

Why it earns a slot

Anything with an LLM in it renders Markdown, and models emit it by default. Because it builds React nodes rather than injecting HTML, you get XSS safety without sanitising strings yourself.

Know before you commit

Tables, strikethrough and autolinks need remark-gfm — the frequent 'why is my table plain text' bug. Re-parsing on every token makes streaming chat slow unless you memoize.

Getting started

npm install react-markdown remark-gfm
