Custom datepicker options in Angular JHipster project

I am new to JHipster and learning how it structured and customized.

Not globally, but in one component view only I want to know where to modify the generated date-picker, in this case to only allow selecting a date that falls on a Monday.

The generated component html:

<div class="form-group">
    <label class="form-control-label" jhiTranslate="deploymentApp.plan.startDate" for="field_startDate">Start Date</label>
    <div class="d-flex">
         <input id="field_startDate" type="datetime-local" class="form-control" name="startDate" formControlName="startDate" placeholder="YYYY-MM-DD HH:mm"/>
    </div>
</div>

And from the component.ts. The only date related code block:

ngOnInit(): void {
this.activatedRoute.data.subscribe(({ plan }) => {
  if (!plan.id) {
    const today = moment().startOf('day');
    plan.startDate = today;
  }

  this.updateForm(plan);

  this.areaService.query().subscribe((res: HttpResponse<IArea[]>) => (this.areas = res.body || []));
  });
}

In the Javascript/HTML this would have be achieved with java script inside the script tags.

Where is the datepicker customised in JHipster?

You don't need to add new dependencies since JHipster already integrates ng-bootstrap.

To enable ng-bootstrap datepicker you only have to change this:

<input id="field_startDate" type="datetime-local" class="form-control" name="startDate" 
       formControlName="startDate" placeholder="YYYY-MM-DD HH:mm"/>

into this:

<input id="field_startDate" class="form-control" name="startDate" 
       formControlName="startDate" placeholder="YYYY-MM-DD"
       ngbDatepicker #d="ngbDatepicker" (click)="d.toggle()" [markDisabled]="markDisabled"/>

If you notice I've added a "markDisabled" property that points to a function of the same name, so in your component TS file you'll need to add something like this:

markDisabled(date: NgbDate): boolean {
  const dateMoment = moment(date.year + '-' + date.month + '-' + date.day, 'YYYY-MM-DD');
  return dateMoment.isoWeekday() !== 7;
}

Since moment.isoWeekday() returns a number [1-7] for the day of the week this should disable all days except for mondays.

There are many other ways to do this, e.g. you could use NgbCalendar.getWeekday() instead of moment. I just tend to use moment for everything date related for consistency.

Not sure what you wanna achieve is possible since JHipster uses browser's datepicker: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/datetime-local

The type attribute might help you achieve what you want.
