previewHead

類型：(head: string) => string

以程式碼調整 Storybook 的預覽 <head>。最常用於擴充套件作者。

如果您不需要以程式碼調整預覽 head，您可以將腳本和樣式新增至preview-head.html 來代替。

例如，您可以根據環境有條件地新增腳本或樣式

.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)'],
  previewHead: (head) => `
    ${head}
    ${
      process.env.ANALYTICS_ID ? '<script src="https://cdn.example.com/analytics.js"></script>' : ''
    }
  `,
};
 
export default config;
