Currently, the props on
Cookie
all have| undefined
, even though none of them actually ever useundefined
as a value. If we get rid of| undefined
, though, we get a TypeScript error complaining that the prop is not definitively assigned in the constructor. This is because we useObject.assign
to initialize props, and I guess TypeScript just can't quite handle that. So, to get rid ofundefined
as a false possible value, we have to manually assign every prop. A bit more verbose, but not a significant change.Additionally, the cookie constructor options are identical to the props of
Cookie
, excluding the methods, so I changed the type from explicitly listing everything to just a mapped type, for simpler maintenance. I wasn't sure if that would be a good idea, because sometimes mapped types get mangled, but the result type is still readable, so I think it's fine.nb: This was originally part of #377, but has been split out for easier review.
