ChineseFrontend Refactor Planner
前端重构规划工具
Create safe, phased refactor plans for complex frontend code.
为复杂的前端代码创建安全、分阶段的重构计划。
Refactor Assessment
重构评估
Identify Issues: Large components (>300 lines), prop drilling, duplicate logic, poor performance, accessibility gaps, tight coupling, untested code
Prioritize: By risk (high-traffic pages first) and impact (user-facing bugs prioritized)
Plan Phases: Break into small, testable increments
问题识别：大型组件（超过300行）、属性透传、重复逻辑、性能不佳、可访问性缺陷、紧耦合、未测试代码
优先级排序：按风险（高流量页面优先）和影响（面向用户的bug优先）排序
阶段规划：拆分为小型、可测试的增量任务
Common Refactor Patterns
常见重构模式
Component Splitting: Extract sub-components, create compound components, separate logic from presentation
State Management: Lift state up, move to Context/Zustand, remove unnecessary state
Performance: Memoization (useMemo/useCallback), code splitting, lazy loading, virtualization
Accessibility: Add ARIA labels, keyboard navigation, focus management, semantic HTML
Testing: Add tests before refactoring, test after each change
组件拆分：提取子组件、创建复合组件、分离逻辑与视图
状态管理：提升状态层级、迁移至Context/Zustand、移除不必要的状态
性能优化：记忆化处理（useMemo/useCallback）、代码拆分、懒加载、虚拟化
可访问性优化：添加ARIA标签、键盘导航、焦点管理、语义化HTML
测试：重构前添加测试，每次变更后进行测试
Phased Approach
分阶段实施方法
Phase 1 - Stabilize: Add tests, fix critical bugs, document current behavior
Phase 2 - Extract: Pull out utilities, create smaller components, reduce complexity
Phase 3 - Simplify: Remove dead code, consolidate duplicates, optimize state
Phase 4 - Polish: Performance optimization, accessibility audit, documentation
阶段1 - 稳定化：添加测试、修复关键bug、记录当前行为
阶段2 - 提取拆分：抽离工具函数、创建更小的组件、降低复杂度
阶段3 - 简化优化：移除死代码、合并重复逻辑、优化状态管理
阶段4 - 打磨完善：性能优化、可访问性审计、文档更新
Risk Mitigation
风险缓解
Feature flags for gradual rollout, A/B testing refactored vs original, monitor error rates, have rollback plan, peer review all changes, incremental deployment.
使用功能标志逐步发布，对重构版本与原始版本进行A/B测试，监控错误率，制定回滚计划，所有变更需经同行评审，增量部署。
Done Criteria
完成判定标准
Code coverage >80%, performance metrics improved, accessibility score 95+, no regressions in tests, code review approved, documentation updated.
代码覆盖率>80%，性能指标提升，可访问性得分95+，测试无回归，代码评审通过，文档已更新。
