NgbDate momentJS adapter for Bootstrap datepicker

ngb-date-moment-adaptater.ts

import { Injectable } from '@angular/core';
import { NgbDateAdapter, NgbDateStruct } from '@ng-bootstrap/ng-bootstrap';
import * as moment from 'moment';

@Injectable()
export class NgbDateMomentAdapter extends NgbDateAdapter<moment.Moment> {

  fromModel(date: moment.Moment): NgbDateStruct {
    if (!date) {
      return null;
    }
    return { year: date.year(), month: date.month(), day: date.day() };
  }

  toModel(date: NgbDateStruct): moment.Moment {
    if (!date) {
      return null;
    }
    return moment(date.year + '-' + date.month + '-' + date.day, 'YYYY-MM-DD');
  }
}

This was a helpful reference implementation, but I believe there might be two bugs with it:

• month() in momentjs is zero-based so you need to offset for that in the fromModel(...) method by adding +1
• day() in momentjs returns "day of week", so you'll want date() instead

For what it's worth to someone, I've created this public gist with a different implementation that doesn't seem to have those issues (and some jasmine tests to check that it doesn't).
