Get locale format with momentjs

Question

I am trying to recover the date format according to the location. For example, if I use moment.locale('fr') retrieve "DD/MM/YYYY" or retrieve "YYYY/MM/DD" with moment.locale('en'). As you can see, I use MomentJS for my date management.

Is there a MomentJS function to recover the format?

If I have understood your issue, then this can resolve it. – Janeanjaneczka

Answer 1

What I was looking for was:

moment().creationData().locale._longDateFormat.L

I found the answer thanks to Aprillion. Thanks!

You can access it in a way that you don't read private variables: moment().creationData().locale.longDateFormat('L'); – Milone

Answer 2

moment.localeData().longDateFormat('L') // "MM/DD/YYYY"

and

moment.localeData('fr').longDateFormat('L') // "DD/MM/YYYY"

seems better

in new moment js slash is replaced with point "MM/DD/YYYY" => "MM.DD.YYYY" – Yablon

Answer 3

I had the same issue, I get a more sophisticated way to solve this problem, just with:

moment().format('L')

Instead of this verbose solution with eslint warning:

moment().creationData().locale._longDateFormat.L

I am not getting it with first solution, only second works. (First gives me, eg: "10.09.2019", second gives me "DD.MM.YYYY"). – Governess

Answer 4

moment().creationData().locale.longDateFormat('L');   

// MM/DD/YYYY
