Missing definition from union type when triggered from JSX tag name
#43,636 opened on Apr 11, 2021
Description
Bug Report
This is a sample code for have a clean issue.
import React from 'react';
class A {
Renderer = RendererA;
}
class B {
Renderer = RendererB;
}
const RendererA = () => {
return <div> A </div>;
};
const RendererB = () => {
return <div> B </div>;
};
const TestRendererTypes = () => {
const AB: A | B = null; // just for the demo, AB can be A or B !
AB.Renderer; //🟩 okey cool,ts find all refs !
const LostRef = <AB.Renderer />; //🟥 not cool ,ts seem remove refs !
return LostRef;
};
🙁 Actual behavior
Ts decode only one reference to a function jsx when using inside tag </>
It should show both Renderer ref here !

🙂 Expected behavior
We should get all refs like that's . (working if use only a variable ref without a jsx tag <></> )

The example is basic, but inside my project i losing all refs, and this is a issu if i need fast track where a rendering is pointing !
And also will give incorrect props Intelisence !
Example here is missing all my others plugins !
But if i add a direct ref like that's , i can get all refs, but is polluting my code

It seem that's TS have some difficulty to understand JSX !
Is there a hacky and (clean way) to fix this ? or tell me if you guys have temp solutions ?
I hope i exposed correctly my issue !
thanks @+
