[JavaScript] DateUtils 만들기

그냥 한번 짜놓으면은 편한 나만의 공통 DateUtil을 만들어 보았다 . 소스를 첨부하겠다. 

export const formatDate = (date: Date): string => {
  return `${date.getFullYear()}-${(date.getMonth() + 1).toString().padStart(2, "0")}-${date
    .getDate()
    .toString()
    .padStart(2, "0")}`;
};

const getDateAgo = (days: number): string => {
  const date = new Date();
  date.setDate(date.getDate() - days);
  return formatDate(date);
};

const getWeeksAgo = (weeks: number): string => {
  return getDateAgo(weeks * 7);
};

const getMonthsAgo = (months: number): string => {
  const date = new Date();
  date.setMonth(date.getMonth() - months);
  return formatDate(date);
};

export const DateUtils = {
  today: formatDate(new Date()),

  // Days 1일전 ~ 7일전
  oneDayAgo: getDateAgo(1),
  twoDaysAgo: getDateAgo(2),
  threeDaysAgo: getDateAgo(3),
  fourDaysAgo: getDateAgo(4),
  fiveDaysAgo: getDateAgo(5),
  sixDaysAgo: getDateAgo(6),
  sevenDaysAgo: getDateAgo(7),

  // Weeks 1주전 ~ 4주전
  oneWeekAgo: getWeeksAgo(1),
  twoWeeksAgo: getWeeksAgo(2),
  threeWeeksAgo: getWeeksAgo(3),
  fourWeeksAgo: getWeeksAgo(4),

  // Months 1달전 ~ 12달전
  oneMonthAgo: getMonthsAgo(1),
  twoMonthsAgo: getMonthsAgo(2),
  threeMonthsAgo: getMonthsAgo(3),
  fourMonthsAgo: getMonthsAgo(4),
  fiveMonthsAgo: getMonthsAgo(5),
  sixMonthsAgo: getMonthsAgo(6),
  sevenMonthsAgo: getMonthsAgo(7),
  eightMonthsAgo: getMonthsAgo(8),
  nineMonthsAgo: getMonthsAgo(9),
  tenMonthsAgo: getMonthsAgo(10),
  elevenMonthsAgo: getMonthsAgo(11),
  twelveMonthsAgo: getMonthsAgo(12),
};

사용방법

const [searchParams, setSearchParams] = useState({
  asdfDtMeetFrom: DateUtils.threeMonthsAgo,
  asdfDtMeetTo: DateUtils.today,
  asdfDtInputFrom: DateUtils.threeMonthsAgo,
  asdfDtInputTo: DateUtils.today,
});
