Features and updates in Angular 15
Angular 15 is a major release that comes with several new features and updates. These include improved dependency injection, better lazy loading support, enhanced TypeScript compatibility, Angular Universal pre-rendering support for Angular components, Angular CLI updates for Angular libraries, and more.
Dependency Injection
Dependency Injection has been improved to enable components to access services from any other Angular module in the current application. This change provides greater flexibility to developers when working on enterprise applications requiring complex architectural designs. Additionally, the new Lazy Loading Support makes it easier to load large amounts of code without needing to manually configure lazy loading routes or modules.
TypeScript
TypeScript compatibility has also been upgraded in Angular 15 – including added support for async generators and top-level await. Angular Universal pre-rendering has been added to support Angular components, allowing them to be pre-rendered when they are first loaded. This reduces page load times and gives Angular developers greater control over the loading process.
Angular Command Line Interface
The Angular CLI has also seen several updates in Angular 15. Angular libraries can now be developed with Angular CLI, which enables developers to access a library of reusable code and build custom libraries for their applications. Additionally, support for TypeScript transformers allows developers to write code once and have it automatically transformed according to the needs of their application during compilation.
Directive Composition API
Angular 15 has introduced the Directive Composition API. This API provides developers with a way to compose directives into components and allows Angular applications to be more maintainable and extensible. The Directive Composition API makes it easier for Angular developers to quickly create reusable components that can be used across multiple projects.
Image Directive (NgOptimized Image) is Now Stable
Angular 15 has also made the Image Directive (NgOptimized Image) stable. This feature allows developers to easily optimize images for better performance and smaller file sizes. Images can be uploaded with optimized attributes such as format, size, and resolution to ensure that the image is displayed in a way that reduces memory usage and loads quickly on any device.
Stable MDC-Based Components
Angular 15 has also included a stable version of MDC-Based Components. This feature provides Angular developers with access to Material Design components for Angular applications. Developers can now easily incorporate Material Design elements into their Angular projects, making them look and feel more professional and polished.
CDK (Component Dev Kit) Listbox
The Angular 15 release has also included the new CDK (Component Dev Kit) Listbox. This feature provides Angular developers with a way to create lists of components, making it easier to manage their projects and reuse code across various parts of their applications.
Automatic Language Service Import
Angular 15 provides the ability to automatically import language services from Angular projects. This feature simplifies Angular development by allowing developers to quickly access and use Angular language services without manually configuring them in their projects.
Conclusion:
Angular 15 is now available, and it comes with several features that can help improve your application. These include the standalone API, directive composition API, stable MDC-based components, and CDK list box.
