I'm running a node-app, this is all I have in app.js:

var moment = require('moment');
moment().locale('fr');
console.log(moment.locale())

I expect this to output 'fr' but it outputs 'en' instead, when I

runjs app.js

There is a fr-folder in node_modules/moment/locale.

Here are my packages:

Spent hours on this just to realise I had to import the locale from /dist dir instead. Maybe it's just caused by my setup but might help someone

import moment from 'moment';
import 'moment/dist/locale/fr';

moment.locale('fr');

Test

import fr1 from 'moment/dist/locale/fr';
import fr2 from 'moment/locale/fr';

console.log(fr1); // Locale {_calendar: {…}, ... }
console.log(fr2); // {}

According to the documentation there is a bug that prevents moment.locale from being loaded. So you can use the following code.

var moment = require('moment');
require('moment/locale/fr');
console.log(moment.locale());

You can use:

import moment from "moment";
import "moment/locale/es";

According to the current documentation it is possible:

var moment = require('moment');
moment.locale('fr');
console.log(moment().format());

For node you can use:

moment.updateLocale('es');

I have tested it.

Current document is not correct. In Node.JS you still use this code:

moment.lang('fr');
