I am curious about why use shallowReactive to deal with props

[dddssw]

If props changed,child component should be updated.I want to know more about that to solve a quesion I meet

I pass tableData which type is ref to child component
`
//parent component

const tableData = ref<OrderApi.OrderDetailList[]>([])
... later,tableData will receive data from remote interface

//child component
const props = defineProps < { tableData: OrderApi.OrderItem[] } > ()
const {tableData}=props
console.log(isProxy(tableData),'sss')

I print tableData ,find it is a proxy,and should be a reference of tableData of parent component ,Later I watch tableData in child component.when tableData gets remote data in parent component.The watch don't run,but It isn't a proxy ? I am in a mess🤔️

Disclaimer: I can only offer a probable explanation because your example code is a bit too short and incomplete. I.e.: what watch? I don't see any,

Likely, your problem is not related to shallowProxy, or reactive objects in general.

Your problem is rooted in the fact that you destructure the props object. Which breaks reactivity for the destructured properties indirectly, because the new variable has no connection to the original object anymore - this is just Javascript.

I am sorry for expressing broken,I start a new discussion with playground,thank
