: 总结和建议这个改动通过引入
React.useRef
来优化useGlobalCache
钩子,有效地解决了内存占用问题。这是一个很好的性能优化,符合 PR 的目标。然而,为了确保代码的稳定性和可靠性,我建议:
- 添加单元测试,特别关注
fullPathStr
的稳定性及其对组件行为的影响。- 进行性能基准测试,量化内存使用的改善情况。
- 考虑添加注释,解释为什么使用
useRef
以及它如何解决内存问题,这将有助于未来的代码维护。最后,建议在合并此 PR 之前,让团队中的另一位开发者进行代码审查,以获得额外的洞察和反馈。

: 优化看起来不错,但需要进行全面测试这个改动通过使用
React.useRef
来创建fullPathStr
的稳定引用,很好地解决了频繁调用useEffectCleanupRegister
导致内存过多占用的问题。这种优化可以减少不必要的重渲染和函数调用,从而提高性能。然而,为了确保这个改动不会引入任何意外的副作用,建议进行以下验证:
- 全面测试组件的行为,确保
fullPathStr
的稳定性没有影响其他依赖于它的逻辑。- 进行性能测试,验证内存占用是否如预期那样减少。
- 检查是否有其他地方依赖于
fullPathStr
的动态性,如果有,可能需要相应调整。您可以运行以下脚本来检查
fullPathStr
在代码库中的其他用法:如果脚本没有输出结果,说明
fullPathStr
只在当前文件中使用,改动的影响范围有限。
求能尽快merge代码😄 |

fullPath
每次 render 都是在上面的 fullPath = [prefix, ...keyPath]
重新组合,这个 useMemo 的 deps 永远都不会命中。

+1,如果想要用 useMemo 来优化代码,deps 应该放 fullPath 本身而不是 [fullPath]
。
另外不太理解为什么缓存 join
会影响内存占用,理论上 useMemo
反而会导致内存占用增加。
Summary by CodeRabbit
fullPathStr
变量在组件渲染中的不一致性问题,确保其在多个渲染之间保持稳定。
