📝 Walkthrough

概述

遍历

在 Bubble.tsx 文件中，主要通过使用 React.useMemo 对 avatarNode 和 mergedContent 变量进行性能优化。新的实现通过记忆化（memoization）这些变量，确保只有在特定依赖项发生变化时才重新计算，从而减少不必要的重新渲染。变更专注于性能改进，未改变组件的核心功能。

🪧 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.

115-118: 建议：考虑 messageRender 的性能影响

使用 useMemo 缓存 mergedContent 是个好主意，但要注意以下几点：

如果 messageRender 是一个内联函数，每次渲染都会创建新的引用，这样会导致缓存失效

建议将 messageRender 也使用 useCallback 包装，以确保缓存的有效性

示例代码：
+ const memoizedMessageRender = React.useCallback(
+   (content: any) => messageRender(content),
+   [messageRender]
+ );

  const mergedContent = React.useMemo(
-   () => (messageRender ? messageRender(typedContent as any) : typedContent),
+   () => (messageRender ? memoizedMessageRender(typedContent as any) : typedContent),
    [typedContent, messageRender],
  );

109-112: 优化：使用 useMemo 缓存 avatarNode 是个好的改进！

通过 useMemo 缓存 avatarNode 可以避免在 avatar prop 没有变化时的不必要重渲染，这是一个很好的性能优化。依赖数组的设置也很准确。
