A carefully crafted date picker for React

import toMoment from '../toMoment'

const CONFIG = {
  // the format in which days should be displayed in month view
  dayFormat: 'D',

  // the format in which months should be displayed in year view
  monthFormat: 'MMMM',

  // the format in which years should be displayed in decade view
  yearFormat: 'YYYY'
}

const f = (mom, format) => toMoment(mom).format(format)

export default {

  day(mom, format) {
    return f(mom, format || CONFIG.dayFormat)
  },

  month(mom, format) {
    return f(mom, format || CONFIG.monthFormat)
  },

  year(mom, format) {
    return f(mom, format || CONFIG.yearFormat)
  }
}
