name	Mind Map HTML Output
description	Generate a self-contained, interactive HTML mind map file powered by the Mind Elixir core. Use when a user wants to turn outlines, markdown, notes, or structured text into a standalone .html file that renders a editable mind map in any browser (a "canvas-capable" client) — no build step required.

Mind Map HTML Output

Turn any hierarchical content (bullet outline, markdown headings, meeting notes, a topic tree, structured JSON) into a single standalone .html file that renders an interactive mind map using the Mind Elixir core loaded from a CDN. The file opens directly in any browser — it is the "canvas client". No npm install, no bundler.

This is the right skill when the user says things like "把这段内容做成思维导图", "export a mind map as html", "生成一个可以直接打开的思维导图网页", or "用 mind-elixir 内核输出 html 思维导图".

When to use

• The deliverable is a file the user can open/share, not a component inside an existing app.
• The user wants zero-setup output (double-click → mind map).
• Input is prose/outline/markdown that must first be structured into a tree.

If the user instead wants to embed Mind Elixir into a React/Vue project, use the Integrate Mind Elixir skill. For image-only export, use Export Mind Map as Image.

Workflow

1. Collect / parse the content. Accept free text, markdown, or a tree. Reduce it to a single-rooted hierarchy.
2. Build the MindElixirData JSON (see below). Prefer JSON when you need styling, icons, tags, links, or images. For a plain nested-list outline you may instead use plaintextConverter (optional, see end).
3. Produce the HTML file from the template assets/template.html: replace __TITLE__ with a title and __MINDMAP_DATA__ with the pretty-printed MindElixirData JSON object. Keep everything else intact.
4. Deliver the .html file via present_files so the user can open it in the built-in preview or a browser. Tell them the toolbar buttons (PNG / SVG / 保存数据 / 导出 HTML) let them re-export or snapshot edits.

MindElixirData shape

{
  nodeData: {            // required: the root node
    topic: '中心主题',
    id: 'root',          // stable ids help avoid re-layout fl/jump
    expanded: true,
    // style: { fontSize: '20', color: '#d9434e', background: '#fff0f0' },
    // tags: ['重要'],
    // icons: ['⭐'],
    // hyperLink: 'https://example.com',
    // image: { url: 'https://.../logo.png', height: 80, width: 80 },
    children: [
      {
        topic: '分支 1',
        id: 'b1',
        expanded: true,
        children: [
          { topic: '子节点 1-1', id: 'b1-1' },
          { topic: '子节点 1-2', id: 'b1-2' },
        ],
      },
      { topic: '分支 2', id: 'b2' },
    ],
  },
  direction: 1,          // optional: 0|1|2|3 — 或设置 options.direction
  theme: {               // optional
    name: 'Latte',
    palette: ['#dd7878', '#ea76cb', '#8839ef', '#40a02b', '#209fb5', '#1e66f5'],
    cssVar: { '--main-color': , : , : , :  },
  },
  
}

Render options (set on new MindElixir(options)): el, direction: MindElixir.LEFT | MindElixir.RIGHT, toolBar, contextMenu, keypress, and optional markdown: (text) => parser(text) if topics contain markdown/rich text.

CDN notes (important)

• Pin to the major version so the API stays compatible:
  https://cdn.jsdelivr.net/npm/mind-elixir@5/dist/MindElixir.js
https://cdn.jsdelivr.net/npm/mind-elixir@5/dist/MindElixir.css
• The CSS file is MindElixir.css (not style.css) on the CDN — match the package's dist output.
• PNG/SVG export use Mind Elixir's built-in mind.exportPng() / mind.exportSvg() — no @zumer/snapdom dependency needed for the standalone file.

Optional: convert a plain outline with plaintextConverter

If the input is already an indentation/markdown bullet list, you can convert it without hand-writing JSON. In a page/script with the module available:

import { plaintextToMindElixir } from 'https://cdn.jsdelivr.net/npm/mind-elixir@5/dist/PlaintextConverter.js'
const data = plaintextToMindElixir(`- 中心主题
  - 分支 1
    - 子节点
  - 分支 2`)

Then pass data into the template's __MINDMAP_DATA__ slot. Plaintext format supports [^id] anchors, {color:...} node styling, } summaries, and > arrows — see the Streaming Mindmap skill for the full grammar.

Tips & pitfalls

• Always give the root and every node a unique, stable id; regenerate ids deterministically from content paths to avoid the whole graph re-rendering on refresh.
• Keep topics short; long text hurts layout. Put detail in child nodes.
• The standalone file needs internet access on first open (CDN). If the user needs a fully offline file, download MindElixir.js + MindElixir.css and rewrite the two CDN URLs to relative/local paths.
• exportPng() is async and may return null if capture fails — the template guards against that.
