Angular 15, the company’s latest offering, is set to rule the tech market once again as the most popular open-source front-end framework. There were many interesting new experimental features in Angular 14 as well as arranged code best practices. It is worth noting, however, that Angular 15 offers a level of stability that was lacking in its predecessor.
There is no doubt that the recent update of Angular 14 has been much awaited by those who already know the framework. We will now take a closer look at Angular 15 after its recent release.
Version 15 of Angular was released by Angular on November 16th, 2022. A variety of features and upgrades have been integrated with the latest version of Angular to provide an enhanced development experience. With the release of the previous version of Angular, the team introduced several interesting features. Programmers, enterprises, and tech lovers have all been attracted to the most recent version of Angular Features and Updates.
What is New in Angular 15?
Developers can build their applications faster and with less code using the new API system in AngularJS 15. There are a number of new features in AngularJS 15 including:
1. Stable Standalone APIs
Now that standalone components are stable in Angular v15, it’s good news. In this way, the standalone component feature has been removed from the “Developer Preview” stage.
Developers can now create Angular applications without any modules using Angular 15.
If you’re a junior Angular developer looking to simplify your development practices by streamlining your development experience, this is the best news for you.
It’s now possible to use Angular standalone components across multiple versions of Angular. The new version is fully compatible with Angular Elements, routers, as well as HTTP clients.
Angular applications can be easily bootstrapped using standalone APIs.
2. An Overview of Directive Composition API
The reusability of directives in a framework is something every developer loves. There was a demand for this API in the Angular community, and finally, the team listened to the community and implemented it.
So, the feature request made on GitHub has finally found its way into Angular v15. Code usability has been elevated to a whole new level with the Directive Composition API. By using the ultimate code reuse strategy, developers can enhance a wide range of elements with directives. An Angular compiler can also make all of this possible.
3. Better Debugging with Stack Traces
Developers using Angular will be pleased to know that Google finally responded to their request. It was difficult to understand the error message given to the community. In addition, since debugging is an integral part of development, there is room for improvement in this area.
The stack traces in Angular 15 have been improved and made more meaningful to resolve this issue. With this approach, developers will be able to create stack traces that are linked to only the code frames they modified, simplifying error messaging.
4. Imports are unwrapped by the router
As a result of lazy loading, default exports are now automatically unwrapped by the router. This further simplifies the router and reduces boilerplate. For lazy loading to be enabled, the router will search for the default export and import the lazy file it finds directly into the code if it finds it.
5. Stable MDC-based Components
It is now complete to refactor the Angular material components using Material Design Components for Web (MDC). Angular now conforms even more closely to Material Design specifications, reuses code from primitives developed by Material Design, and integrate Material 3 once the style tokens are available.
It is likely you will need to change some styles in your application as a result of the new DOM and CSS, particularly if CSS is overriding styles within the migrated components.
An extensively outdated component implementation has already been deprecated in the most recent Angular version, v15. The “legacy” import can therefore be used by developers to restore them.
6. Compact Disc Listbox (CDK)
CDK provides behaviour primitives for creating user interface elements that can be used in the Component Development Kit. Developers can modify WAI-ARIA Listbox patterns’ interaction as needed with CDK Listbox, a new feature in Angular v15.
The behaviours you interact with are defined by your keyboard interactions, your layouts in bidirectional directions, and your attention management. Specified host elements correspond to a certain set of ARIA roles for each directive.
7. Stable Image Directives
Image loading performance can be optimized using the NgOptimizedImage directive. The latest version of the application has reached stable form after careful observation by developers.
Land’s End conducted an experiment where this feature improved the loading times of their Largest Contentful Paint (LCP) images by 75%. NgOptimizedImage is the solution if you want to optimize your image loading performance.
8. Support for experimental ESbuilds
9. Dependency Injection
Programming languages can be made easier for developers by using some tricks and methods. Developers can help themselves by providing dependencies on other objects by using Dependency Injection.
It’s the ability of an object to provide dependencies to another object that is referred to as dependency injection.
Angular v14 to v15 upgrade: how to do it?
It is quite simple for developers to upgrade from Angular v14 to Angular v15. There are only a few options for developers to choose from, depending on their requirements. The button to demonstrate updating can be found once they select the options. Developers can upgrade to Angular 15 by clicking on the button.
Web development is mostly done with Angular. With its long history and ability to handle any situation, it has proven to be a reliable solution. The underlying architecture of Angular has been dramatically changed in version 15. Client-side web applications are built using Angular, a progressive framework. For building complex single-page web applications, it is one of the most popular open-source libraries. Type Script is used by Angular for writing dynamic content and HTML templates for generating it. Components, services, and other reusable code make it easy to build flexible and scalable applications.
