从 postrgresql 检索的节点日期正在转换为不需要的格式

Question

I have a pg select

db.query("SELECT * from users where id ="+userId).then(data => {
   console.log(data[0].birth_date)
})

Which returns

1997-08-11T22:00:00.000Z

I have prepared a function to parse the data

function filterDate(date) {
console.log("inside")
console.log(date)
var stringDate = date.toString();
var result = stringDate.match(/(?:(?!T).)*/)
console.log(result)
console.log("inside")
return result[0];

}

Which should return 1997-98-11 Problem is that, whenever the.toString() happens inside filterDate, it preformats the date to an invalid string 'Tue Aug 12 1997 00:00:00 GMT+0200 (GMT+02:00)', . I was handling it in the client side, so I was directly doing it after a res.send, and it was working fine. But now if i date.toString() in the server side it reformats it to a weird format. How do I avoid it and mantain the first format?

Answer 1

Using moment npm

  function filterDate(date) {
    var stringDate = moment(date).format('YYYY-MM-DD').toString();
    var result = stringDate.match(/(?:(?!T).)*/)
    return result[0];
  }

And then

deathDate = moment(filterDate(birth_date)).add(yearsToLive, 'years')

Will assign the proper format as YYYY-MM-DD
