DX for typed events

[cassiozen]

Hey @devanshj, when using types events, I'm getting a confusing error message. Here's a sample case:

1 - I have a types "UPDATE" event that requires a string value
2 - When trying send({ type: "UPDATE" }) it gives me an error (right, it is missing the value)
3 - Problem is, the error says Type '"UPDATE"' is not assignable to type '"some other type"':

Here is an example (the examples/form with this added send on line 57:

I understand that TypeScript is showing one example of a correct possible value - but since you apparently can bend TypeScript to your will 🤪, can anything be done here?

[devanshj]

you apparently can bend TypeScript to your will 🤪

HAHAHAHA this is 100% going to twitter xD

Could you send that code? I can't repro minimally. EDIT: oh wait you said it's from examples, looking into it

[devanshj]

This is most probably a bug, so i'll report it to typescript team, meanwhile let me see if I can find a workaround

[devanshj]

The repro is simpler than I thought xD I was guessing it takes time to compute hence typescript was showing bad errors

And the workaround is pretty simple - to add an overload, sending a PR

Stands true ;)

sending a PR

I'll publish the beta after we merge this then.

For reference and reminder to revert overloads when #45217 gets fixed.
