Partial type does not accept plain empty object literal as a default about flow

[gkz]

Technically you can pass in empty as the type argument, and Partial<empty> is empty, and {} is not a valid value for empty

[insonifi]

The documentation:

This utility converts all of an object or interface's named fields to be optional, while maintaining all the object's other properties (e.g. exactness, variance).

I understand that there could only be an indexed type. Hence empty cannot be used for a partial type.

[gkz]

empty is a subtype of all types including interface {}

I agree what you are doing is what seems intuitive however

[insonifi]

What do you think is the idiomatic way to handle it, then?

[gkz]

There is no way to do that currently. What I'm saying is that what we are currently doing is technically correct and safe, however it obviously doesn't align with what people intuitively think should happen, so we should think about it.
