问题背景，项目需要做持久化缓存，需要获取类似vue2中的$data数据去存储

<script setup>
import { ref, getCurrentInstance, toRaw } from 'vue'

const msg = ref('Hello World!')
defineExpose({msg})
const instance = getCurrentInstance();
const handleTestClick = () => {
  console.log(instance.exposeProxy.msg)
}
</script>

<script setup>
import { ref, getCurrentInstance, toRaw } from 'vue'

const msg = ref('Hello World!')
defineExpose({msg})
const instance = getCurrentInstance();
const handleTestClick = () => {
  console.log(instance.exposeProxy.msg)
}
</script>

@Zero1306 In the Production mode, the template used variable are in the function scope, so can't get it from getCurrentInstance. I think the @baiwusanyu-c 's way use defineExpose is right, or you can use pinia.

This is due to the fact that Vue uses different compilation modes (inline) in dev and prod builds, which is the design.
I think you should not use setupState this internal Api, using expose is relatively correct
