Is it possible to have a conditional value within
groq
?
EX: If a user sets an unique DATE we should use that date instead of
_updatedAt
value?
Would love to do this on the groq side so the
date
property always has a value.

Hi pbj, you could use the
coalesce()
function for this. It takes a number of attribute references and returns the value of the first attribute that is non-null. So if you’d like to default to the
_updatedAt
value if no
date
exists, this should work:
*[_type == 'post']{
  ...,
  'date': coalesce(date, _updatedAt)
}
