How to integrate vega chart to stencil js component?

问题

我正在尝试使用vega图表创建一个stencil js组件,根据vega手册,我安装了3个包:

npm install vega
npm install vega-lite
npm install vega-embed

并尝试导入

import { Vega } from 'vega'

但出现以下错误信息:

模块'“vega”'没有导出成员'Vega'

有人成功将vega图表集成到stencil js中吗?

提前感谢您!

and trying to import

and get this.

>Module '"vega"' has no exported member 'Vega'

Did anyone manage to integrate vega chart into stencil js?

Thank you in advance!

根据使用文档

> 在使用捆绑工具时使用 Vega。 如果您使用像 rollup.js 这样的捆绑工具,您可以将 Vega 作为模块导入。
>
> import * as vega from "vega";

请注意,如果您在启用了 Shadow DOM 的组件中使用它,您可能需要将 Vega 作为 container 配置的一部分传递给一个 DOM 节点,而不是一个 CSS 选择器:

class MyComponent {
  container: HTMLDivElement;

  componentDidLoad() {
    new vega.View(vega.parse(spec), {
      renderer:  'canvas',  // 渲染器(canvas 或 svg)
      container: this.container,   // 父 DOM 容器
    });

    // ...
  }

  render() {
    return <div ref={el => this.container = el}></div>
  }
}
英文:

According to the usage docs:

> Using Vega with a bundler. If you use Vega with a bundler like rollup.js, you can import Vega as a module.
>
> import * as vega from &quot;vega&quot;;

Note that if you're using it in a component with Shadow DOM enabled you will probably need to pass Vega, in the container configuration, a DOM node instead of a CSS selector:

class MyComponent {
  container: HTMLDivElement;

  componentDidLoad() {
    new vega.View(vega.parse(spec), {
      renderer:  &#39;canvas&#39;,  // renderer (canvas or svg)
      container: this.container,   // parent DOM container
    });

    // ...
  }

  render() {
    return &lt;div ref={el =&gt; this.container = el}&gt;&lt;/div&gt;
  }
}
