[Panthro]

Subject of the issue

Add an option to return null when empty for schema strict applications

Expected behaviour

When an element return empty, add the element as a null

Eg:

{
  "id":"0",
  "name":null
}

You can use filters as a workaround:

var Xray = require('x-ray');
var x = Xray({
  filters: {
    nullify: function(value) { return value.length ? value : null; }
  }
});

x('https://google.com', {
  empty: 'empty | nullify'
});

Having the same issue myself and tried a filter with no joy. Tried yours out of interest. No such luck. Have you tried this yourself with any luck?
