The dt-datepicker can be used to select a date with (or without) a time.

<h2>Full datepicker</h2>
<dt-datepicker
  [startAt]="startAt"
  [disabled]="isDatepickerDisabled"
  [isTimeEnabled]="isDatepickerTimeEnabled"
  [showTodayButton]="showTodayButton"
></dt-datepicker>
<dt-checkbox [(ngModel)]="isDatepickerDisabled">Disabled</dt-checkbox>
<dt-checkbox [(ngModel)]="isDatepickerTimeEnabled"
  >Enabled Time Mode</dt-checkbox
>
<dt-checkbox [(ngModel)]="showTodayButton">Enable Today Button</dt-checkbox>
<h2>Calendar</h2>
<dt-calendar
  [startAt]="startAt"
  [showTodayButton]="showTodayButton"
></dt-calendar>
<h2>Calendar body only</h2>
<dt-calendar-body [activeDate]="startAt"></dt-calendar-body>
<h2>Timepicker</h2>
<dt-timepicker [disabled]="isTimepickerDisabled"></dt-timepicker>
<dt-checkbox [(ngModel)]="isTimepickerDisabled">Disabled</dt-checkbox>

Initialization

In order to use the datepicker in your template you need the <dt-datepicker> element. Similarly, you can also use the <dt-calendar>, <dt-calendar-body>, as well as <dt-timepicker> elements individually in your template.

Imports

You have to import the DtDatepickerModule to use the dt-datepicker. The datepicker works by default with the DtNativeDateAdapter, which is based off the functionality available in JavaScript's native Date object. This is limited when it comes to setting the parse format. Therefore, if necessary, a custom DateAdapter can be implemented in order to handle the formatting/parsing library of your choice.

import { NgModule } from '@angular/core';
import { DtDatepickerModule } from '@dynatrace/barista-components/experimental/datepicker';

@NgModule({
  imports: [DtDatepickerModule],
})
class MyModule {}

Also, in order to enable dark mode, the DtThemingModule has to be imported and DT_OVERLAY_THEMING_CONFIG needs to be provided, such as:

import { NgModule } from '@angular/core';
import { DtDatepickerModule } from '@dynatrace/barista-components/experimental/datepicker';
import {
  DT_DEFAULT_DARK_THEMING_CONFIG,
  DT_OVERLAY_THEMING_CONFIG,
} from '@dynatrace/barista-components/core';

@NgModule({
  imports: [DtDatepickerModule, DtThemingModule],
   providers: [
    {
      provide: DT_OVERLAY_THEMING_CONFIG,
      useValue: DT_DEFAULT_DARK_THEMING_CONFIG,
    },
})
class MyModule {}
