@angular/core

What are @angular/core's main functionalities?

"@Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'My Angular App'; }"

"constructor(private myService: MyService) {}"

"@Directive({ selector: '[appHighlight]' }) export class HighlightDirective { constructor(el: ElementRef) { el.nativeElement.style.backgroundColor = 'yellow'; } }"

18.0.0-next.6 (2024-04-25)

Breaking Changes

animations

• Deprecated matchesElement method has been removed from AnimationDriver as it is unused.

core

• async has been removed, use waitForAsync instead.

http

• By default we now prevent caching of HTTP requests that require authorization . To opt-out from this behaviour use the includeRequestsWithAuthHeaders option in withHttpTransferCache.

  Example:

  withHttpTransferCache({
    includeRequestsWithAuthHeaders: true,
  })
  

platform-browser

• Deprecated StateKey, TransferState and makeStateKey have been removed from @angular/platform-browser, use the same APIs from @angular/core.

Deprecations

common

• getCurrencySymbol, getLocaleCurrencyCode, getLocaleCurrencyName, getLocaleCurrencySymbol, getLocaleDateFormat, getLocaleDateTimeFormat, getLocaleDayNames, getLocaleDayPeriods, getLocaleDirection, getLocaleEraNames, getLocaleExtraDayPeriodRules, getLocaleExtraDayPeriods, getLocaleFirstDayOfWeek, getLocaleId, getLocaleMonthNames, getLocaleNumberFormat, getLocaleNumberSymbol, getLocalePluralCase, getLocaleTimeFormat, getLocaleWeekEndRange, getNumberOfCurrencyDigits

http

• HttpClientModule, HttpClientXsrfModule and HttpClientJsonpModule

  As mentionned, those modules can be replaced by provider function only.
