How to set an empty array as a query's initial value without it inferring undefined?

[franciscohermida]

Considering this example:

const todos = ref([]) // initial value is [] so I don't have to check for undefined in the code

async function fetchData(){
  todos.value = await apiCall() // <- always returns array
}
fetchData()

Pass it with initialData or placeholderData

• https://pinia-colada.esm.dev/api/@pinia/colada/interfaces/UseQueryOptions.html#initialData-
• https://pinia-colada.esm.dev/api/@pinia/colada/interfaces/UseQueryOptions.html#placeholderData-

So there is no way to set the type to Todo[] instead of Todo[] | undefined in pinia colada?

Yes, because the data can still be set to undefined afterwards or placeholder data can also return undefined

If the type is Todo[] Typescript should complain if I assign undefined to the Ref afterwards. I make sure to always return empty array if something goes wrong. Placeholder is also empty array

Right now you have to cast it but I should be able to improve this type in particular in the future

Should be fixed by #114 🎉

Thank you!

A small token to show my appreciation, hoping to encourage more gestures like this in open source
