.where('x', 'is not', null) and correspond type's nullability
Not sure if this even possible in typescript (although all of the work Kysely already makes it seem magical). But let's say we have a column 'x' that has type
string | null. Is it possible to write a query that ends up resulting in a final type of string after using .where('x', 'is not', null) or any similar method?Solution:Jump to solution
Hey 👋
Due to compiler performance and type maintainability, Kysely doesnt narrow the type in this case. We've recently introduced the
.$narrowType that allows you to narrow the output type safely....7 Replies

.$narrowType that allows you to narrow the output type safely.but in theory, it would be possible?
