常见陷阱

决策失误案例

// 反模式：过度追求新技术
const antiPattern1 = {
  mistake: '选择最新的CSS-in-JS库',
  consequence: '生态不成熟，遇到问题难以解决',
  lesson: '选择成熟稳定的方案，除非有充分的理由',
};

// 反模式：忽视团队能力
const antiPattern2 = {
  mistake: '在CSS新手团队引入CSS-in-JS',
  consequence: '学习成本高，开发效率降低',
  lesson: '选择符合团队技能水平的方案',
};

// 反模式：性能过度优化
const antiPattern3 = {
  mistake: '在小项目中使用复杂的零运行时方案',
  consequence: '配置复杂，开发体验差',
  lesson: '根据实际性能需求选择，不要过度优化',
};

// 反模式：方案混用过度
const antiPattern4 = {
  mistake: '同时使用3-4种样式方案',
  consequence: 'Bundle增大，代码混乱，维护困难',
  lesson: '限制方案数量，最多2种(主方案+工具方案)',
};

// 反模式：忽视长期维护
const antiPattern5 = {
  mistake: '选择快速开发但难维护的方案',
  consequence: '技术债累积，重构成本高',
  lesson: '平衡短期效率和长期可维护性',
};

总结

样式方案选型关键要点：

1. 系统评估：技术、团队、项目三个维度
2. 量化决策：使用评分系统辅助决策
3. POC验证：实践验证而非纸上谈兵
4. 渐进迁移：降低风险，平滑过渡
5. 持续优化：定期review，适时调整

记住：没有完美的方案，只有最适合的方案。根据项目实际情况，做出理性的技术选择。
