Angular material introduced a new date picker component found here.

I want the date returned by this component to be in the format yyy-mm-dd but I am not su

Answer 1

Worked perfectly when the date is typed from the keyborard and returned null in initiation to avoid the massage 'Invalid date' in md-datapicker directive:

$mdDateLocaleProvider.formatDate = function(date) {
  return date ? moment(date).format('DD/MM/YYYY') : null;
};

$mdDateLocaleProvider.parseDate = function(dateString) {
  var m = moment(dateString, 'DD/MM/YYYY', true);
  return m.isValid() ? m.toDate() : new Date(NaN);
};
