Improve typescript documentation to show how to use vue without imports that would require module bundler

[realmerx]

Since currently type definitions for vue need to be exported, you have to use import:

//ItemComponentl.ts
import Vue from 'vue'

const ItemComponent = Vue.extend({
})

To get them work without import you can create custom type definition with declare global:

//global.d.ts - name does not matter
import { VueConstructor } from 'vue'

declare global {
    const Vue: VueConstructor
}

Sorry, I'm lost. What part of the documentation are we looking at?

[realmerx]

No, I am sorry for not being clear enough :) https://vuejs.org/v2/guide/typescript.html

[phanan]

Right, thanks! Still, I'm not very sure what change(s) you want to see there. Do you think a PR would explain your intention better?

[realmerx]

Sure, I'll create a pull request for this.

[realmerx]

Finally got time to do that :)

Thank you for spotting this issue and for your work on the related PR!

Closing this now as vuejs/vue#9912 got merged and now we can use global Vue without any additional setup required.
