How to load locale dynamically

See original GitHub issue

I am developing an ionic 2 app. To localize angular2-moment I just included lang module in app.module.ts after including angular2-moment like this and that automatically pulled spanish language:

import { MomentModule} from 'angular2-moment';
import 'moment/locale/es';

My app use cordova-plugin-globalization to dinamically set app language so, how can I load the lang locale dynamically?

Thanks!

I made a pipe and it worked to actualize the date on a language change:

@Pipe({
  name: 'dynamicMoment'
})
export class MomentPipe implements PipeTransform {
  /**
   * MomentPipe constructor
   * @param {TranslateService} translate
   */
  constructor(private translate: TranslateService) {
  }

  /**
   * Make moment dynamic
   * @param {string} value
   * @param {string} format
   * @returns {any}
   */
  transform(value: string, format?: string): any {
    // make the moment format configurable
    format = format ? format : 'MMMM Do YYYY';
    // get the initial value
    const initVal = moment(value).locale(moment.locale()).format(format);
    // insert the value into a new behaviour subject. If the language changes, the behaviour subject will be 
    // updated
    const momentObs = new BehaviorSubject<string>(initVal);
    this.translate.onLangChange.subscribe(() => {
      // format the new date according to the new locale
      const val = moment(value).locale(moment.locale()).format(format);
      momentObs.next(val);
    });
    return momentObs; // needs to be piped into the async pipe
  }

}

Hi, I managed to do so by ` moment. locale (‘es’); when a language change is detected, however, I haven’t found a way yet to update the currently printed ones.
