Support empty values without warning

See original GitHub issue

When used on a null value, logs warning into console:

Could not build a valid `moment` object from input.

I would assume that not all values are mandatory and would expect this filter to be permissive in this regard. Please remove the warning.

Possibly replace

if (!input || !date.isValid())


if (input && !date.isValid())

After some upgrade this filter stopped reflecting MomentJS locale. Creating this 9-line filter in main.js covered all my requirements, quit nagging me in the console AND respects the locale set in MomentJS:

import moment from 'moment'

Vue.filter('moment', function (value, format) {
  if (value === null || value === undefined || format === undefined) {
    return ''
  if (format === 'from') {
    return moment(value).fromNow()
  return moment(value).format(format)

Ditched this library and never looked back.
