Introducing the Socket Python SDK
The initial version of the Socket Python SDK is now on PyPI, enabling developers to more easily interact with the Socket REST API in Python projects.
@angular/core
Advanced tools
The @angular/core package is a fundamental part of Angular, a popular front-end web application platform. It provides the critical runtime parts of the Angular framework, including the component decorator, directives, dependency injection, and the core Angular APIs necessary for building dynamic single-page web applications.
Components
Components are the building blocks of Angular applications. They control a patch of screen called a view. The @Component decorator indicates that the class immediately below it is a component and provides metadata about the component.
"@Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'My Angular App'; }"
Dependency Injection
Dependency Injection (DI) is a design pattern used in Angular to make components or classes dependent on interfaces rather than concrete implementations. This improves modularity and testability.
"constructor(private myService: MyService) {}"
Directives
Directives are classes that add additional behavior to elements in your Angular applications. With Angular's built-in directives, you can manage forms, lists, styles, and what users see.
"@Directive({ selector: '[appHighlight]' }) export class HighlightDirective { constructor(el: ElementRef) { el.nativeElement.style.backgroundColor = 'yellow'; } }"
React is a popular JavaScript library for building user interfaces. It focuses on a component-based architecture similar to Angular but uses a different syntax and design philosophy. React emphasizes a one-way data flow and virtual DOM for efficient rendering.
Vue.js is a progressive JavaScript framework used for building UIs and single-page applications. It is designed from the ground up to be incrementally adoptable. Vue also focuses on the ViewModel part of the MVVM pattern and employs a reactive and composable data model.
The sources for this package are in the main Angular repo. Please file issues and pull requests against that repo.
Usage information and reference details can be found in Angular documentation.

Errors that are thrown during ApplicationRef.tick
will now be rethrown when using TestBed
. These errors should be
resolved by ensuring the test environment is set up correctly to
complete change detection successfully. There are two alternatives to
catch the errors:
expect(() => TestBed.inject(ApplicationRef).tick()).toThrow()
TestBed
will reject any outstanding ComponentFixture.whenStable
promises. A jasmine test,
for example, could write expectAsync(fixture.whenStable()).toBeRejected()
.As a last resort, you can configure errors to not be rethrown by
setting rethrowApplicationErrors
to false
in TestBed.configureTestingModule
.
Router.errorHandler
property has been removed.
Adding an error handler should be configured in either
withNavigationErrorHandler
with provideRouter
or the errorHandler
property in the extra options of RouterModule.forRoot
. In addition,
the error handler cannot be used to change the return value of the
router navigation promise or prevent it from rejecting. Instead, if you
want to prevent the promise from rejecting, use resolveNavigationPromiseOnError
.Resolve
interface now includes
RedirectCommand
