如何导入 Polaris React 组件？

Question

I am brand new to frontend development, so I think this question is quite basic, but I have not been able to find the answer myself though.我是前端开发的新手，所以我认为这个问题很基本，但我自己还没有找到答案。 I want to use the Shopify App Bridge which means using Polaris React components to create the UI for a Shopify App.我想使用 Shopify App Bridge，这意味着使用 Polaris React 组件为 Shopify 应用创建 UI。 I am new to JS, React and npm, but followed some basic tutorials to get started.我是 JS、React 和 npm 的新手，但遵循了一些基本教程开始。 I am lost when I get to the instruction "First, import the component into your project:" at https://polaris.shopify.com/components/get-started#navigation .当我在https://polaris.shopify.com/components/get-started#navigation看到“首先，将组件导入您的项目：”说明时，我迷路了。 I am guessing the import line should be the first line in my js file, but my basic example stops working when I add the import line.我猜导入行应该是我的 js 文件中的第一行，但是当我添加导入行时，我的基本示例停止工作。 I tried installing polaris with this command: npm install @shopify/polaris --save我尝试使用以下命令安装 polaris： npm install @shopify/polaris --save

My files before I add the import line:在添加导入行之前我的文件：

My HTML file:我的 HTML 文件：

<html>
<head>
    <link rel="stylesheet" href="https://sdks.shopifycdn.com/polaris/3.4.0/polaris.min.css" />
</head>
<body>
<div id="root"></div>

<!-- Load React. -->
<!-- Note: when deploying, replace "development.js" with "production.min.js". -->
<script src="https://unpkg.com/react@16/umd/react.development.js" crossorigin></script>
<script src="https://unpkg.com/react-dom@16/umd/react-dom.development.js" crossorigin></script>
<script src="https://unpkg.com/babel-standalone@6/babel.min.js"></script>

<script  src="scripts/test.js"></script>
</body>
</html>

My test.js file:我的 test.js 文件：

class Hello extends React.Component {
  render() {
    return React.createElement('div', null, `Hello ${this.props.toWhat}`);
  }
}

ReactDOM.render(
  React.createElement(Hello, {toWhat: 'World'}, null),
  document.getElementById('root')
);

My package.json file:我的 package.json 文件：

{
  "name": "somename",
  "version": "1.0.0",
  "dependencies": {
    "@shopify/polaris": "^3.4.0",
    "react": "^16.7.0",
    "react-dom": "^16.7.0"
  }
}

When I add "import {AppProvider, Button} from '@shopify/polaris';"当我添加“从‘@shopify/polaris’导入{AppProvider, Button}；” to the top of the js file, the page cannot be rendered, but I cannot figure out why.到js文件的顶部，页面无法呈现，但我不知道为什么。

What am I missing in order to be able to import the components?为了能够导入组件，我缺少什么？

Thanks, -Louise谢谢，-路易斯

You can import it like this:您可以像这样导入它：

import {AppProvider, Page, Card, Button} from '@shopify/polaris';
import '@shopify/polaris/styles.css';

And use it like this并像这样使用它

<AppProvider>
    <Page title="Example app">
      <Card sectioned>
        <Button onClick={() => alert('Button clicked!')}>Example button</Button>
      </Card>
    </Page>
  </AppProvider>
