• Developing and implementing custom directives.

Pipes

• Understanding the utility of pipes in Angular 17.
• Using built-in pipes for date, currency, and JSON formatting.
• Crafting and applying custom pipes.

Services

• Importing and exporting modules for reuse.

Data Binding

• Distinguishing between one-way and two-way data binding.
• Implementing property binding, event binding, and the banana-in-a-box syntax.
• Utilizing template reference variables.

Routing

• Understanding the importance of routing in Angular 17.
• Creating and configuring application routes.
• Navigating between views using routerLink and router.navigate().
• Managing route parameters, query parameters, and fragments.

Forms

• Distinguishing between template-driven and reactive forms.
• Building and validating forms with controls, groups, and arrays.
• Applying built-in validators such as required, minLength, and maxLength.
• Developing custom validation logic.

HTTP Client

• Understanding the role of the HTTP client in Angular 17.
• Executing HTTP requests to interact with backend services.
• Managing asynchronous data streams using observables.
• Modifying or handling HTTP requests and responses with interceptors.

New, Declarative Control Flow

• Explaining the new template control block syntax and its benefits for conditional rendering, looping, and empty collection handling.
• Demonstrating the use of new blocks, including @if, @else, @switch, @case, @default, @for, and @empty.
• Comparing the new syntax with legacy equivalents like *ngIf, *ngSwitch, and *ngFor.
• Highlighting how the new control blocks support zoneless applications with signals.

Deferred Loading Blocks

• Explaining deferred loading and its impact on application performance and user experience.
• Introducing the @defer control block for lazy-loading content and dependencies.
• Providing examples of @defer usage for components, directives, pipes, animations, and styles.
• Detailing the integration of the @defer block with the view transitions API.

View Transitions API

• Explaining the benefits of the view transitions API for customizing animations between views.
• Introducing the withViewTransitions directive for enabling these transitions.
• Demonstrating the directive with various transition types, such as fade, slide, zoom, and flip.
• Discussing the interaction between the view transitions API, the Angular router, and browser history.

Other Features and Improvements

• Summarizing additional enhancements in Angular 17, including:
• Support for defining @Component.styles as a string.
• Lazy-loadable animation code.
• Compatibility with TypeScript 5.2.
• Stabilization of the core signal API.
• Removal of Node.js v16 support, with v18.13.0 as the new minimum requirement.
• Esbuild becoming the default builder, with Vite powering the default dev server.
