Typing the return of `toRefs`

[absolutejam]

Howdy,

First of all, I just want to say how much I enjoy using Vue and the new composition api is amazing. Great job 👍

I'm using Typescript in my project and I've generally been using pretty basic interfaces and inference where possible, but I hit a problem yesterday wherein the return type of toRefs() wasn't valid.

I spent quite a while poking around in the composition-api source, inspecting type definitions, and eventually I realised that I could create the following type which will wrap an existing type/interface's properties in Ref.

type Refs<T> = {
  [P in keyof T]: Ref<T[P]>;
};

But I couldn't see something available/documented to provide this. Is this something that should be part of the library or would people be expected to provide something themselves?

Regards,
James.

Sounds like a bug. Can you provide a small reproduction please?

Created a pull on vue-next vuejs/core#1037

I can add that to the PR #311 👍

[LinusBorg]

Awesome, do that after the vue-next PR is accepted, just to be sure that we stay in sync.

Thanks!
