154-156: Effective validation setup with proper change detectionThe changes in ngAfterViewInit properly add the date format validator, update the control's validity, and trigger change detection to reflect validation status immediately in the UI.
One consideration: validators are typically added during form initialization rather than in ngAfterViewInit. Since this works for your use case, it's acceptable, but consider moving validation setup to form initialization in future refactors.
1-313: Consider adopting OnPush change detection strategySince you're using manual change detection with ChangeDetectorRef, this component might benefit from using OnPush change detection strategy, which could improve performance by reducing unnecessary change detection cycles.
You could add this to your @component decorator:
@Component({ selector: 'app-date-time', templateUrl: './date-time.component.html', styleUrls: ['./date-time.component.scss'], + changeDetection: ChangeDetectionStrategy.OnPush, providers: [ { provide: DateAdapter, useClass: MomentDateAdapter, deps: [MAT_DATE_LOCALE] }, { provide: MAT_DATE_FORMATS, useValue: MY_FORMATS } ] })Don't forget to add the import:
import { ChangeDetectionStrategy } from '@angular/core';

35-45: Well-implemented date format validator functionThe new
dateFormatValidatorfunction is cleanly implemented, following Angular's validator pattern. It properly checks if a date value exists and is valid using the optional chaining operator for safe property access.src/app/greencity/modules/events/components/event-editor/components/create-event-dates/date-time/date-time.component.html (1)
10-10: Error message now correctly references the day controlGood change to update the error message condition to check the
daycontrol for thedateIncorrecterror instead of thestartDatecontrol. This aligns with the new validation approach and ensures users receive appropriate feedback.src/assets/i18n/en.json (1)
1362-1362: Improved error message with clear date format instructionsThe updated error message is much more helpful, providing explicit guidance on the accepted date formats (MM/DD/YYYY or month DD YYYY). This will significantly improve the user experience when entering dates.
src/assets/i18n/ua.json (1)
1401-1401: Localization properly adapted for Ukrainian date format conventionGood job adapting the date format guidance for Ukrainian users (DD.MM.YYYY or DD month YYYY), respecting the common day-first format used in Ukraine. This ensures consistent localization across the application.
src/app/greencity/modules/events/components/event-editor/components/create-event-dates/date-time/date-time.component.ts (6)
1-1: Nice addition of ChangeDetectorRef for proper change detectionThe import of ChangeDetectorRef is necessary for the manual change detection triggering used later in the component lifecycle.
10-10: Good import of the custom validatorThis import properly brings in the dateFormatValidator that will be used to validate date formats.
14-14: Excellent enhancement of date format supportSupporting multiple date input formats ('DD MMM, YYYY', 'DD.MM.YYYY', 'MMM DD, YYYY', 'MM/DD/YYYY') provides a much better user experience, allowing users to enter dates in the format they're most comfortable with.
17-17: Good switch to localized long date formatUsing 'LL' for the display format ensures the date is shown in a user-friendly, localized format appropriate for the current language.
74-75: Proper dependency injectionThe inclusion of DateAdapter and ChangeDetectorRef as private dependencies follows Angular best practices.
134-136: Good defensive programmingThe early return when newDate is falsy prevents unnecessary processing and potential errors during date conversion or manipulation.
