# HTML 节点插件
|
||||
|
||||
Infinite Canvas 画布节点插件:用沙箱 iframe 渲染 HTML。源码里的 `{{input}}` 会被替换为上游文本节点内容。
|
||||
|
||||
## 构建
|
||||
|
||||
```bash
|
||||
npm install
|
||||
npm run build # 产物 dist/html.js,并同步到 web/public/plugins/html.js
|
||||
npm run dev # watch
|
||||
```
|
||||
|
||||
## 安装
|
||||
|
||||
画布 → 左上菜单「节点插件」→ 安装 URL 填 `/plugins/html.js`(或托管后的公网 URL)。
|
||||
|
||||
插件契约见 `plugins/canvas/README.md`。
