previewBody

类型：(body: string) => string

¥Type: (body: string) => string

以编程方式调整 Storybook 的预览 <body>。最常由插件作者使用。

¥Programmatically adjust the preview <body> of your Storybook. Most often used by addon authors.

如果你不需要以编程方式调整预览主体，则可以将脚本和样式添加到 preview-body.html。

¥If you don't need to programmatically adjust the preview body, you can add scripts and styles to preview-body.html instead.

例如，你可以根据环境有条件地添加脚本或样式：

¥For example, you can conditionally add scripts or styles, depending on the environment:

.storybook/main.ts

// Replace your-framework with the framework you are using (e.g., react-webpack5, vue3-vite)
import type { StorybookConfig } from '@storybook/your-framework';
 
const config: StorybookConfig = {
  framework: '@storybook/your-framework',
  stories: ['../src/**/*.mdx', '../src/**/*.stories.@(js|jsx|mjs|ts|tsx)'],
  previewBody: (body) => `
    ${body}
    ${
      process.env.ANALYTICS_ID ? '<script src="https://cdn.example.com/analytics.js"></script>' : ''
    }
  `,
};
 
export default config;
