Summary of Changes

Hello @EmilyyyLiu, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request implements a standardized and flexible system for managing CSS class prefixes across components, beginning with the Calendar component. By leveraging the ConfigProvider, it allows for both global and granular control over component class names, which is crucial for consistent theming, preventing styling conflicts, and improving maintainability in diverse application environments.

Highlights

  • Unified prefixCls Provision: The Calendar component now utilizes a unified approach for providing custom CSS class prefixes, integrating with the ConfigProvider's getPrefixCls utility.
  • Customizable Calendar Component: A new prefixCls prop has been added to the CalendarProps interface, allowing developers to specify a custom class prefix for individual Calendar instances, overriding any global configuration.
  • Enhanced ConfigProvider: The ConfigProvider has been extended to include a getPrefixCls function and a prefixCls prop, enabling global configuration of component class prefixes and providing a centralized mechanism for their generation.
  • Improved Test Coverage: New unit and snapshot tests have been introduced for both the Calendar and ConfigProvider components to ensure the correct application and behavior of the custom prefixCls functionality.
  • Documentation Updates: The documentation for the ConfigProvider has been updated in both English and Chinese to reflect the addition of the new prefixCls prop and its usage.

Code Review

本次 PR 很好地实现了通过 ConfigProvider 统一提供自定义类名前缀的功能,并将其应用在了 Calendar 组件上。整体实现清晰,测试覆盖也比较到位。我提出了一些关于性能优化和测试解耦的建议,希望能让代码质量更高。

test('should apply custom prefixCls', () => {
const { container } = render(
<ConfigProvider prefixCls='config-prefix'>
<Calendar />
</ConfigProvider>
)
expect(container.querySelector('.config-prefix-calendar')).toBeTruthy()
expect(container).toMatchSnapshot()
})

config-provider 的测试文件不应该依赖 Calendar 这样的上层业务组件,这会造成不好的模块分层。建议移除对 Calendar 的导入,并使用一个简单的本地测试组件来代替,以实现测试的解耦。

  test('should apply custom prefixCls', () => {
    const DemoComponent = () => {
      const { getPrefixCls } = useConfig()
      const prefixCls = getPrefixCls('calendar')
      return <div className={prefixCls} />
    }
    const { container } = render(
      <ConfigProvider prefixCls='config-prefix'>
        <DemoComponent />
      </ConfigProvider>
    )
    expect(container.querySelector('.config-prefix-calendar')).toBeTruthy()
    expect(container).toMatchSnapshot()
  })

const getPrefixCls = (suffixCls?: string, customizePrefixCls?: string) => {
if (customizePrefixCls) {
return customizePrefixCls
}
const mergedPrefixCls =
config.prefixCls || parentConfig.prefixCls || defaultPrefixCls
return suffixCls ? `${mergedPrefixCls}-${suffixCls}` : mergedPrefixCls
}

getPrefixCls 函数在每次 ConfigProvider 渲染时都会被重新创建。为了优化性能,避免下游消费组件不必要的重渲染,建议使用 React.useCallback 将其包裹起来进行 memoization。

  const getPrefixCls = React.useCallback(
    (suffixCls?: string, customizePrefixCls?: string) => {
      if (customizePrefixCls) {
        return customizePrefixCls
      }
      const mergedPrefixCls =
        config.prefixCls || parentConfig.prefixCls || defaultPrefixCls
      return suffixCls ? `${mergedPrefixCls}-${suffixCls}` : mergedPrefixCls
    },
    [config.prefixCls, parentConfig.prefixCls]
  )
