markdown

A small Markdown → HTML renderer, written entirely in Lumen.

Unlike the FFI packages (quickjs, sqlite), markdown is pure Lumen — no C shim, no native library, nothing to install. Import it by URL and use it.

Use

import { render } from "https://lumen-lang.org/package/std-contrib/markdown/markdown.ts";

console.log(render("# Title\n\nSome **bold**, *italic*, `code`, and a [link](https://x.io).\n\n- one\n- two"));

API

API	Meaning
`render(md: string): string`	render a Markdown document to an HTML fragment

Supported syntax

A practical subset of CommonMark:

ATX headings # … ######
paragraphs
inline **bold**, *italic*, ` code , text`
unordered lists (- / *)
blockquotes (>)
fenced code blocks (``` ` ```)
horizontal rules (---)

HTML metacharacters (& < > ") are escaped. Multi-row tables, ordered lists, nested lists, and reference links are future additions.

Performance

markdown is fast. Rendering a typical ~3 KB document in a tight loop — renders per second, higher is better:

Renderer	renders/sec
markdown (this package)	6,775
markdown-it	2,020
marked	1,064

About 3.4× faster than markdown-it and 6.4× faster than marked on the same document.
