Deprecation warning in moment js

Deprecation warning in moment js

I need help I’m getting a warning on my code that has a value provided is not in a recognized ISO format. and I change my variable today with moment function and still it doesn’t work.
Here’s the warning error

Deprecation warning: value provided is not in a recognized ISO format. moment construction falls back to js Date(), which is not reliable across all browsers and versions. Non ISO date formats are discouraged and will be removed in an upcoming major release. Please refer to http://momentjs.com/guides/#/warnings/js-date/ for more info.

Solution 1:

Check out all their awesome documentation!

Here is where they discuss the Warning Message.

String + Format

Warning: Browser support for parsing strings is inconsistent. Because there is no specification on which formats should be supported, what works in some browsers will not work in other browsers.

For consistent results parsing anything other than ISO 8601 strings, you should use String + Format.

moment("12-25-1995", "MM-DD-YYYY");

String + Formats (multiple formats)

If you have more than one format, check out their String + Formats (with an ‘s’).

If you don’t know the exact format of an input string, but know it could be one of many, you can use an array of formats.

moment("12-25-1995", ["MM-DD-YYYY", "YYYY-MM-DD"]);

Please checkout the documentation for anything more specific.

Timezone

Checkout Parsing in Zone, the equivalent documentation for timezones.

The moment.tz constructor takes all the same arguments as the moment constructor, but uses the last argument as a time zone identifier.

var b = moment.tz("May 12th 2014 8PM", "MMM Do YYYY hA", "America/Toronto");

EDIT

//...
var dateFormat = "YYYY-M-D H:m"; //<-------- This part will get rid of the warning.
var aus1_s, aus2_s, aus3_s, aus4_s, aus5_s, aus6_s, aus6_e;
if ($("#custom1 :selected").val() == "AU" ) {
    var region = 'Australia/Sydney';

    aus1_s = moment.tz('2016-9-26 19:30', dateFormat, region);              
    aus2_s = moment.tz('2016-10-2 19:30', dateFormat, region);              
    aus3_s = moment.tz('2016-10-9 19:30', dateFormat, region);                  
    aus4_s = moment.tz('2016-10-16 19:30', dateFormat, region);                 
    aus5_s = moment.tz('2016-10-23 19:30', dateFormat, region);
    aus6_s = moment.tz('2016-10-30 19:30', dateFormat, region);
    aus6_e = moment.tz('2016-11-5 19:30', dateFormat, region);
} else if ($("#custom1 :selected").val() == "NZ" ) {
    var region = 'Pacific/Auckland';

    aus1_s =  moment.tz('2016-9-28 20:30', dateFormat, region);
    aus2_s =  moment.tz('2016-10-4 20:30', dateFormat, region);
    aus3_s =  moment.tz('2016-10-11 20:30', dateFormat, region);
    aus4_s =  moment.tz('2016-10-18 20:30', dateFormat, region);
    aus5_s =  moment.tz('2016-10-25 20:30', dateFormat, region);
    aus6_s =  moment.tz('2016-11-2 20:30', dateFormat, region);
    aus6_e =  moment.tz('2016-11-9 20:30', dateFormat, region);
}

Doing this works for me:

moment(new Date("27/04/2016")).format

Solution 3:

I ran into this error because I was trying to pass in a date from localStorage. Passing the date into a new Date object, and then calling .toISOString() did the trick for me:

const dateFromStorage = localStorage.getItem('someDate');
const date = new Date(dateFromStorage);
const momentDate = moment(date.toISOString());

This suppressed any warnings in the console.

Solution 4:

use moment in your function like this

 moment(new Date(date)).format('MM/DD/YYYY')

Solution 5:

This answer is to give a better understanding of this warning

Deprecation warning is caused when you use moment to create time object, var today = moment();.

If this warning is okay with you then I have a simpler method.

Don’t use date object from js use moment instead. For example use moment() to get the current date.

Or convert the js date object to moment date. You can simply do that specifying the format of your js date object.

ie, moment("js date", "js date format");

eg:

moment("2014 04 25", "YYYY MM DD");

(BUT YOU CAN ONLY USE THIS METHOD UNTIL IT’S DEPRECIATED, this may be depreciated from moment in the future)

Solution 6:

Parsing string with moment.js.

const date = '1231231231231' //Example String date
const parsed = moment(+date);
