如何在 React Native 中获取格式化的日期字符串

Question

In many apps we can see the date formatting like this.

If it's today, then print hh:mm,
If it's yesterday, then print yesterday,
If it's in this week, then print day of week, (ex, Wednesday)
If it's in this year, then print MM/dd
else print YY/MM/dd

Something like this. How can I implement in React Native or javascript? Is there library for this?

Answer 1

Use library momentjs . There is function isSame which compare given date with year,month or day. Like

moment().isSame('2010-01-01', 'year');  // true
moment().isSame('2011-01-01', 'month'); // false, different year
moment().isSame('2010-02-01', 'day'); //
moment().isSame('2010-02-01', 'week'); //

In your case, 1st on

const dateString = moment().isSame('2018-01-01', 'day') ? moment('2018-01-01 5:55').format('hh:mm') : else check for other condition

Better go from year to month to week and week to day.
