依据vue官方文档，vue2在2023年12月31日终止维护。因此决定将原来的岁月云记账升级到vue3，预计工作量有点大，于是想着把过程记录下来。

新系统使用的技术栈如下，可以看到至少有下面几点变化
- 代码编译从
webpack调整为vite - 前端界面框架从
element-ui升级到element-plus - 状态管理从
vuex调整为pinia - 支持
typescript

1 element-plus相关
1.1 slot插槽
slot-scope="scope" 批量更改为#default="scope"
v-slot="scope"统一调整为#default="scope"
2 api请求
看到下面这个结果真是头大，工程师是不是在摸鱼，复制、粘贴不用动脑，为何不写一个指令来实现。只能一个个改。这个里面的工作量非常之大，得耐心去调整。
新的api
看看原来的store方式调用api，写法确实冗余拖拉，没有新的方式简洁
新方式，一句话定义完了，不用搞那么多绕绕。
有一些人并不是直接用dispatch模式，例如这样的，是直接引用了api里面的方法
另外需要注意加上async
还有人在页面直接写了axios调用,这些也需要统一调整过来，真是一个修行的过程，花了我一天的时间，将256处直接用axios的请求调整过来。
继续重构代码，发现还有这样打开界面的,通过window.open直接打开界面,这样的代码都属于比较隐蔽的。
3 存储相关
可以参考我之前写的文档多租户平台前端存储结构的选择，工程师采用vuex存储状态，肯定不合理，结果就是多租户被架空。像这类问题估计99%的前端开发工程师面试一定能答上来，但是实际应用就只能呵呵了。
4 页面组件依赖
待补充。。。。
