Parse string to date with moment.js

moment was perfect for what I needed. NOTE it ignores the hours and minutes and just does it's thing if you let it. This was perfect for me as my API call brings back the date and time but I only care about the date.

function momentTest() {

  var varDate = "2018-01-19 18:05:01.423";
  var myDate =  moment(varDate,"YYYY-MM-DD").format("DD-MM-YYYY");
  var todayDate = moment().format("DD-MM-YYYY");  
  var yesterdayDate = moment().subtract(1, 'days').format("DD-MM-YYYY");   
  var tomorrowDate = moment().add(1, 'days').format("DD-MM-YYYY");

  alert(todayDate);

  if (myDate == todayDate) {
    alert("date is today");
  } else if (myDate == yesterdayDate) {
    alert("date is yesterday");
  } else if (myDate == tomorrowDate) {
    alert("date is tomorrow");
  } else {
    alert("It's not today, tomorrow or yesterday!");
  }
}

No need for moment.js to parse the input since its format is the standard one :

var date = new Date('2014-02-27T10:00:00');
var formatted = moment(date).format('D MMMM YYYY');

You need to use the .format() function.

MM - Month number

MMM - Month word

var date = moment("2014-02-27T10:00:00").format('DD-MM-YYYY');
var dateMonthAsWord = moment("2014-02-27T10:00:00").format('DD-MMM-YYYY');

I always seem to find myself landing here only to realize that the title and question are not quite aligned.

If you want a moment date from a string:

const myMomentObject = moment(str, 'YYYY-MM-DD')

From moment documentation:

Instead of modifying the native Date.prototype, Moment.js creates a wrapper for the Date object.

If you instead want a javascript Date object from a string:

const myDate = moment(str, 'YYYY-MM-DD').toDate();
