Learning: 在 React/Taro 组件中使用 setTimeout 或 setInterval 时,应当在组件卸载时通过 useEffect 的清理函数清除定时器,以防止内存泄漏。可以使用 useState 存储定时器 ID,并在 useEffect 的返回函数中清除。

23-23: 默认启用资源清理,防止内存泄漏

destroy 默认值从 false 改为 true 是一个很好的改进。这确保了组件卸载时会自动取消动画帧(见 Line 272),符合 React 最佳实践,可以有效防止内存泄漏。

需要注意的是,这是一个破坏性变更,依赖旧默认行为的用户需要显式设置 destroy={false} 来保持原有行为。

Tip

📝 Customizable high-level summaries are now available in beta!

You can now customize how CodeRabbit generates the high-level summary in your pull requests — including its content, structure, tone, and formatting.

  • Provide your own instructions using the high_level_summary_instructions setting.
  • Format the summary however you like (bullet lists, tables, multi-section layouts, contributor stats, etc.).
  • Use high_level_summary_in_walkthrough to move the summary from the description to the walkthrough section.

Example instruction:

"Divide the high-level summary into five sections:

  1. 📝 Description — Summarize the main change in 50–60 words, explaining what was done.
  2. 📓 References — List relevant issues, discussions, documentation, or related PRs.
  3. 📦 Dependencies & Requirements — Mention any new/updated dependencies, environment variable changes, or configuration updates.
  4. 📊 Contributor Summary — Include a Markdown table showing contributions:
    | Contributor | Lines Added | Lines Removed | Files Changed |
  5. ✔️ Additional Notes — Add any extra reviewer context.
    Keep each section concise (under 200 words) and use bullet or numbered lists for clarity."

Note: This feature is currently in beta for Pro-tier users, and pricing will be announced later.
