概述

演练

此次更改主要涉及 src/Item.tsx 和 src/Overflow.tsx 中的 renderItem 函数签名和类型定义的修改。变更简化了 ItemProps 和 OverflowProps 接口，将 renderItem 函数从接收单个 ItemWithIndex<ItemType> 参数改为接收 ItemType 和包含 index 的信息对象。测试文件 tests/index.spec.tsx 相应地更新了 renderItem 函数的调用方式。

变更

文件	变更摘要
src/Item.tsx	- ItemProps 接口 item 属性类型从 ItemWithIndex<ItemType> 变为 ItemType - renderItem 函数签名更新为 (item: ItemType, info: { index: number })
src/Overflow.tsx	- OverflowProps 接口 renderItem 属性签名类似更新 - 内部渲染逻辑调整以适应新的函数签名
tests/index.spec.tsx	- 更新 renderItem 函数调用，使用 info.index 替代 item.index

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

59-60: 建议增加更多测试用例

当前测试用例正确验证了新的 renderItem 签名，但建议添加以下测试场景：

• 验证 info.index 在动态数据更新时的正确性
• 验证边界情况（空数组、单个元素等）

src/Item.tsx (2)

11-11: 接口改进很好！

将 renderItem 的签名从单个 item 参数改为 (item, info) 的形式是个很好的改进：

• 使 API 更加明确
• 符合 React 的常见模式
• 提高了类型安全性

Also applies to: 14-14

---

69-71: 实现正确！

renderItem 的调用正确地传递了 index 参数，保持了与接口定义的一致性。

src/Overflow.tsx (3)

27-27: 很好的保持了一致性！

OverflowProps 接口中 renderItem 的签名变更与 Item.tsx 保持一致，这样的同步修改确保了类型安全。

---

349-349: 实现正确且简洁！

移除了 ItemWithIndex 包装，直接传递 item，使代码更加清晰。

---

368-387: 代码格式调整合理！

代码格式的调整提高了可读性，同时保持了功能不变。
