import { parseAndRender } from "@ox-content/napi";

const { html } = parseAndRender("# Hello World", { gfm: true });

Vite Plugin

// vite.config.ts
import { defineConfig } from "vite";
import { oxContent } from "@ox-content/vite-plugin";

export default defineConfig({
  plugins: [
    oxContent({
      srcDir: "docs",
      outDir: "dist/docs",
      highlight: true,

Latest local parse-benchmark run on 2026-03-07 with Node v24.14.0 on Apple M2 Max:

Parse Only (48.7 KB)

Library	ops/sec	throughput	relative
@ox-content/napi	2463	117.22 MB/s	1.00x
md4w (md4c)	735	34.99 MB/s	3.35x slower
markdown-it	639	30.43 MB/s	3.85x slower
marked	362	17.25 MB/s	6.80x slower
remark	32	1.51 MB/s	77.86x slower

Parse + Render (48.7 KB)

Library	ops/sec	throughput	relative
@ox-content/napi	2122	100.97 MB/s	1.00x
md4w (md4c)	1903	90.54 MB/s	1.12x slower
markdown-it	532	25.31 MB/s	3.99x slower
marked	345	16.42 MB/s	6.15x slower
micromark	34	1.62 MB/s	62.35x slower
remark	28	1.33 MB/s	75.81x slower

Run the benchmark with:

node benchmarks/bundle-size/parse-benchmark.mjs

The script now compares against md4w (md4c) by default and will include Bun.markdown.html automatically when bun is installed.

Development

vp install             # Install JS dependencies through Vite+
vp run build:napi      # Build NAPI bindings
vp run build:npm       # Build npm packages
vp run test            # Run tests

The workspace task graph is defined in vite.config.ts, and Node.js is pinned in .node-version.
