升级Vue2.7记录

依赖升级

• vue -> 2.7.8
• 删除vue-template-compiler，@vue/test-util 会用到，需要保留，同步版本和vue相同

this

const { proxy } = getCurrentInstance() 
proxy.$router

import { getCurrentInstance } from 'vue';
// 访问vuex
export const useStore = () => {
  const vm = getCurrentInstance();
  if (!vm) throw new Error('must be called in setup');
  return vm.proxy.$store;
};
// 访问router
export const useRouter = () => {
  const vm = getCurrentInstance();
  if (!vm) throw new Error('must be called in setup');
  return vm.proxy.$router;
};
// 访问route
export const useRoute = () => {
  const vm = getCurrentInstance();
  if (!vm) throw new Error('must be called in setup');
  return vm.proxy.$route;
};

v-deep

[@vue/compiler-sfc] ::v-deep usage as a combinator has been deprecated. Use :deep(<inner-selector>) instead
