69-70: uuid 的实现方案合理使用
useUuid生成唯一标识符是解决 className 依赖问题的好方法。建议添加注释说明这个改动的目的，以便其他开发者理解。建议添加如下注释：
+ // 使用唯一ID避免多个实例间的className冲突 const uuid = useUuid() const classPrefix = 'nut-elevator'
Line range hint
111-116: DOM 查询选择器的更新需要注意性能影响选择器的更新正确地整合了 uuid，但需要注意以下几点：
- 复杂的选择器可能影响性能
- 建议缓存查询结果以优化性能
建议添加结果缓存机制：
+ const selectorCache = useRef<Record<string, any>>({}) const calculateHeight = () => { let height = 0 + const cacheKey = `${classPrefix}-${uuid}-height` + if (selectorCache.current[cacheKey]) { + return selectorCache.current[cacheKey] + } // ... existing code ... + selectorCache.current[cacheKey] = height }Also applies to: 185-190
225-229: 根元素类名更新合理，但建议优化可读性类名的组合逻辑正确，但可以通过使用 classNames 工具函数来提高可读性和维护性。
建议重构为：
- <div - className={`${classPrefix} ${className} ${classPrefix}-${uuid}`} - style={style} - {...rest} - > + <div + className={classNames(classPrefix, className, `${classPrefix}-${uuid}`)} + style={style} + {...rest} + >
架构建议需要调整
useUuidhook 已经被正确抽象到src/utils/use-uuid.ts中，且被多个组件共用，无需重构- 建议添加以下改进：
- 为
useUuidhook 添加单元测试，验证多实例场景下的唯一性- 在
calculateHeight方法中添加错误处理，处理选择器查询失败的情况- 考虑将
uniqueId的前缀从$nut$改为更具语义化的组件前缀🔗 Analysis chain
Line range hint
1-324: 整体架构建议
- 建议将 uuid 相关的逻辑抽象到一个自定义 hook 中，例如
useElevatorId- 考虑添加错误边界处理选择器查询失败的情况
- 建议添加单元测试确保 uuid 的实现能够正确处理多实例场景

2-2: 导入更改看起来合理且有序
引入 useUuid hook 是一个很好的改进，可以确保组件实例的唯一性。导入顺序符合最佳实践，将内部依赖放在外部依赖之后。
