Global config and Global API reference

[NataliaTepluhina]

This PR adds two first parts to the API Reference

• Global Config
• Global API

[Jinjiang]

I probably prefer the title "Application Config" and "Application API" respectively. Because in v3 it's possible to create more than one applications in the same page. So we could customize them separately. That's more like an application-level thing.

Reviewed the config part.

[Jinjiang]

Reviewed the API part. Thanks.

Suggested change

	const MyComponent = app.component('my-component', {})
	const MyComponent = app.component('my-component')

Not sure this would work but I think there should be only one parameter for the getter mode.

[NataliaTepluhina]

Unfortunately, if we skip the second parameter here, MyComponent will be undefined

Hi, I forked your codesandbox demo and made some change to demo my idea: https://codesandbox.io/s/async-components-pbku4?file=/index.html
Seems it returns the registered component as well.

Hi @NataliaTepluhina , not sure you have seen this. Is that helpful? I still think here it should be no second parameter for the getter. Thanks.

[NataliaTepluhina]

Thank you so much for the thorough review @Jinjiang! I've applied all the suggestions besides app.component argument - you can check this sandbox - if we remove the second parameter, app.component will return undefined.

Could you please give this PR a second look? 🙏

Just left some phrasing suggestions, but thanks for starting to put this together! I imagine we'll have more ideas as time goes on, but I think it's good to go!
