如何使用 Luxon 格式化时间（不是日期）？

Question

I need to convert backend-fetched data "17:00" to "5pm". Using moment I just do:

moment('17:00', ['HH']).format('h:mma')

How to achieve the same thing with Luxon ? While moment allows to format times directly, it seems Luxon 'sformat functions require a date (which I don't have).

Any suggestion?

Answer 1

DateTime.fromISO('17:00').toLocaleString(DateTime.TIME_SIMPLE)    // 5:00 PM
DateTime.fromISO('17:00').toFormat('h:mma')                       // 5:00PM
DateTime.fromISO('17:00').toFormat('h:mm a')                      // 5:00 PM

couldn't figure out how to make meridiem lowercase though
https://github.com/moment/luxon/issues/224

EDIT if want in lowercase can do something like this

  const dt = DateTime.fromISO('17:00')
  const meridiem = (dt.hour > 11) ? 'p' : 'a'
  const final =  `${dt.toFormat('h:mm')}${meridiem}m`
