Hey @KaelWD,

Thanks for this. That sure is pretty code! I've been doing typescript for while, but not to this level.

Do you have any resources for where to learn about doing code like you've written in your tests?

I didn't even know you could do this:

Vue.extend({
  computed: get<{
    search: string,
    items: any[]
  }>('products', [
    'search',
    'items',
  ]),

[KaelWD]

If you mean specifically with vue, I don't think there really are any. Otherwise it's mostly just writing TS every day for the past ~year plus a little help from here.

[KaelWD]

Is this ready to merge?

[davestewart]

Sorry @KaelWD - been really distracted with other things.
