We strongly recommend reading this if you plan to use moment with Require.js. Also upgrade to 2.14.0 or above for best experience.

As a start, you might have aquired moment through bower or node_modules or anything else that places moment.js together with a locales directory in a base folder. Then you should use a tool like adapt-pkg-main, or manually -- using packages config.

  packages: [{
    name: 'moment',
    // This location is relative to baseUrl. Choose bower_components
    // or node_modules, depending on how moment was installed.
    location: '[bower_components|node_modules]/moment'
    main: 'moment'

With the above setup, you can require the core with moment and de locale with moment/locale/de.

// only needing core
define(['moment'], function (moment) {
    console.log(moment().format('LLLL'));  // 'Friday, June 24, 2016 1:42 AM'

// core with single locale
define(['moment', 'moment/locale/de'], function (moment) {
    console.log(moment().format('LLLL')); // 'Freitag, 24. Juni 2016 01:42'

// core with all locales
define(['moment/min/moment-with-locales'], function (moment) {
    console.log(moment().format('LLLL')); // 'Freitag, 24. Juni 2016 01:42'

// async load locale
define(['require', 'moment'], function(require, moment) {
  // Inside some module after the locale is detected. This is the
  // case where the locale is not known before module load time.
  require(['moment/locale/de'], function(localeModule) {
    // here the locale is loaded, but not yet in use
    console.log(moment().format('LLLL'));  // 'Friday, June 24, 2016 1:42 AM'

    // Use moment now that the locale has been properly set.
    console.log(moment().format('LLLL')); // 'Freitag, 24. Juni 2016 01:42'

For more complicated use cases please read excellent explanation by @jrburke.

Moment will still create a moment global, which is useful to plugins and other third-party code. If you wish to squash that global, use the noGlobal option on the module config.

    config: {
        moment: {
            noGlobal: true

If you don't specify noGlobal then the globally exported moment will print a deprecation warning. From next major release you'll have to export it yourself if you want that behavior.

For version 2.5.x, in case you use other plugins that rely on Moment but are not AMD-compatible you may need to add wrapShim: true to your r.js config.

Note: To allow moment.js plugins to be loaded in requirejs environments, moment is created as a named module. Because of this, moment must be loaded exactly as as "moment", using paths to determine the directory. Requiring moment with a path like "vendor\moment" will return undefined.

Note: From version 2.9.0 moment exports itself as an anonymous module, so if you're using only the core (no locales / plugins), then you don't need config if you put it on a non-standard location.
