// 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,
      ssg: {
        siteName: "My Docs",

  ],
});

Performance

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

Parse Only (48.7 KB)

Parse + Render (48.7 KB)

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.
