@grafiq/markdown-it

A markdown-it plugin that renders Grafiq mockups from fenced code blocks — with client-side hydration and a built-in fullscreen lightbox.

Because Grafiq renders to <canvas>, the plugin emits an SSR-safe placeholder at build time. On the client, hydrate() turns those placeholders into live, interactive canvases.

Install

yarn add @grafiq/markdown-it @grafiq/core markdown-it

Plugin

import MarkdownIt from "markdown-it";
import grafiq from "@grafiq/markdown-it";

const md = new MarkdownIt().use(grafiq);
md.render("```grafiq\nbutton \"Save\" primary\n```");
// -> <div class="grafiq-mockup" data-grafiq-source="…">…</div>

Options:

md.use(grafiq, {
  langs: ["grafiq", "mockup"], // fence info-strings to intercept
  className: "grafiq-mockup",   // wrapper class
  fallbackSource: true,          // render a <pre> fallback for no-JS
});

Hydration

import "@grafiq/markdown-it/styles.css";
import { hydrate } from "@grafiq/markdown-it/hydrate";

hydrate({
  maxWidth: 720,     // width offered to the renderer
  lightbox: true,    // show the fullscreen ⤢ button (default)
  codeToggle: true,  // show the </> source toggle (default)
  editable: true,    // live-editable source view (default; implies codeToggle)
});

hydrate() is idempotent — already-hydrated mockups are skipped, so it's safe to call on every SPA route change.

Toolbar: code toggle & inline editing

Each hydrated mockup gets a hover toolbar:

• </> — toggle between the mockup and its DSL source.
• ↺ — reset an edited mockup to its original (appears after editing).
• ⤢ — open fullscreen.

With editable on (default), the source view re-renders live as you type — a mini-playground in every code block. Use editable: false for a read-only view, or codeToggle: false to hide the source.

Lightbox

Each hydrated mockup gets a ⤢ button (visible on hover) that opens the same DSL fullscreen. Drive it programmatically:

import { openLightbox, closeLightbox } from "@grafiq/markdown-it/hydrate";
openLightbox('button "Hello" primary');

See the documentation for a VitePress integration example.
