Default value of an object pattern property should not change type if it's assignable about stc

Hi @kdy1, I'd like to give it a try!

Thanks!

Is the object part relevant here? Looks like tsc infers BarProps even when fooProps has type BarProps, without the object intersection.

I would guess we should infer BarProps | DefaultValue if DefaultValue is not assignable to BarProps & object, and just BarProps otherwise. {} is assignable to BarProps & object (or BarProps fwiw), so we should infer BarProps & object

I think you are right, nice catch! Thank you.

I tried incompatible default value and it matches with your observation
