Thanks @jviide! - Add experimental support for.optional(() => x)
The
.optional()
method now supports default value functions for replacingundefined
and missing values from the input and wrapped validator. The functionality is similar to.default(x)
, except thatdefaultFn
has to be a function and is executed for each validation run. This allows patterns like the following:const Item = v.object({ id: v.string() }); const Items = v.array(Item).optional(() => []);
This avoids a common pitfall with using
.default([])
for the same pattern. As the newly created empty arrays are not shared, mutating them is safe(r) as it doesn't affect other validation outputs.This feature is marked experimental for the time being.
