● Stable “NgOptimizedImage” Image Directive
We saw in the Angular 14 version that employing the NgOptimizedImage directive was one
of the best ways to load images quickly. But the fact that it has finally become stable is
wonderful news for Angular developers.
NgOptimizedImage has received a few minor improvements with the release of Angular 15.
➔ Automatic srcset Generation: When asked to upload a specific size of the image, you
can now automatically produce the srcset. The time it takes to download an image will
be reduced.
➔ Fill Mode [experimental]: The Angular 15 feature that fills an image to its parent
container does away with the requirement for declaring image dimensions. If you need
to convert the CSS background image to utilize the image directive or if you don't know
the image size, trust me, it's a fairly appealing concept.](https://image.slidesharecdn.com/whatsnewinangular15-221216073048-5e137ceb/85/What-s-New-in-Angular-15-pptx-7-320.jpg)

Angular 15 has been released. Angular 15 is back with more and more exciting enhancements to make it easier for Angular developers to create powerful applications after the successful launch of Angular 14. Yes, I am aware that everyone is very eager to see what Angular 15 has to offer. So let's begin by examining the new updates that the most recent Angular version 15.
- 4. What is new in Angular 15? The announcement that Angular 15 will launch on November 16, 2022 has Angular developers around the world beaming with joy. Because they had been waiting for a major announcement, which actually occurred, the reason was quite obvious. Angular 15 introduced numerous significant and exciting features, including: ● Stable standalone components API ● Develop a multi-route application ● Directive Composition API ● Stable “NgOptimizedImage” Image Directive ● Easily Reduce Boilerplate in Guards ● Better Stack Traces For Debugging Process ● CDK Listbox ● ESBuild Support of Angular 15 Sounds interesting, correct? These are the most significant changes made in Angular 15 so far.
- 5. What are the Angular 15 Features? Here are the highlighted details on all of these key features of Angular's most recent version, 15. We hope this guide has offered you a clear understanding of Angular and its primary applications. ● Stable Standalone Components API It is the first and most significant enhancement in Angular v15. Without using ngModules, Angular applications can be created quickly and it is among the best illustrations of achieving stability following thorough performance observation and modifications. The finest front-end development tool for learning Angular development practices is Angular 15, whether you're completely new to development or just have a basic understanding of JavaScript. Additionally, Angular standalone components can be used effectively in any Angular project and they work well with Angular components, HttpClient, Routes, and many other applications. With Angular 15, you can easily bootstrap an Angular app with just one component, which is fantastic.
- 6. What are the Angular 15 Features? ● You Can Now Easily Develop a Multi-Route Application You did read that correctly. You can now easily create multi-route apps with Angular 15 thanks to a crucial feature called the router standalone API. ● Angular 15 Comes With Directive Composition API All Angular developers, including myself who work for a top AngularJS development business, were looking forwards to a feature that would make it simple for us to reuse the directives. And the Angular team made it possible for us to do that by including the Directive Composition API and facilitating our development process. Want to know how? By using directives, the Directive Composition API improves the usability of the code and supports host elements. But always keep in mind that only standalone directives are compatible with Directive Composition.

If you need to convert the CSS background image to utilize the image directive or if you don't know the image size, trust me, it's a fairly appealing concept.
- 8. What are the Angular 15 Features? ● Easily Reduce Boilerplate in Guards It’s a practical concept. So let's quickly and thoroughly examine the example. We've first established guards to make sure the user has logged in. @Injectable({ providedIn: 'root' }) export class MyGuardWithDependency implements CanActivate { constructor(private loginService: LoginService) {} canActivate() { return this.loginService.isLoggedIn(); }
- 9. What are the Angular 15 Features? } const route = { path: 'somePath', canActivate: [MyGuardWithDependency] }; Here, you can see that the guard – just isLoggedIn() is one trigger that is called and that LoginService includes the primary logic. This code segment has a lot of boilerplate, therefore we need to cut it down as much as possible. Functional Router Guards make it simple to refactor code into the code provided below with the required boilerplates.
- 10. What are the Angular 15 Features? const route = { path: 'admin', canActivate: [() => inject(LoginService).isLoggedIn()] }; The fact that Functional Guards are completely biodegradable is one of their great features. It, therefore, makes your life easier in a variety of ways, including the development of powerful functionality like factor-like functions, the acceptance of a given configuration, and the return of a guard or function that solves a problem.
- 11. What are the Angular 15 Features? ● Better Stack Traces For Debugging Process Debugging Angular applications has become easier and easier with the release of the most recent version of Angular. Throughout the whole Angular development lifecycle, the Angular development team works to establish a standard for tracing development code regardless of displaying libraries. The improvement of the display of error messages as they arrive is the main goal of creating such stack traces. Developers receive a one-liner error message, for instance, if they discuss earlier iterations of Angular during the code discovery process. And much more to cope with the protracted process to fix that defect. It is essential to consider the priority attribute when utilizing an Angular image directive within a certain component in order to improve the speed of the LCP pictures.

And much more to cope with the protracted process to fix that defect.
- 13. What are the Angular 15 Features? Due to the following factors, developers were unable to interpret the ERROR snippets: ➔ Such error message inputs were entirely the result of third-party dependencies. ➔ You needed to obtain information about where this bug in user interaction occurred. ➔ The Angular community found it somewhat helpful to execute integration with third- party dependencies (with the aid of node modules, zone.js, etc.); thus, it could produce connected stack traces. This was made possible by active and lengthy work with the Angular and Chrome DevTool team.
- 14. What are the Angular 15 Features? ● CDK Listbox Different behavior primitives are provided by the CDK (Component Dev Kit) to aid in the creation of UI components. The WAI-ARIA Listbox pattern's Listbox interactions can now be easily customized by Angular developers thanks to a new primitive in Angular v15 called CDK Listbox. Impressive features like keyboard interactions, bidi layout compatibility, and focus management are provided by the behavioral interactions in this case. Furthermore, it makes no difference whatever directive you employ because they all have associated ARIA roles and corresponding host components.
- 15. What are the Angular 15 Features? ● ESBuild Support of Angular 15 When using the older version of the Angular framework, you may support esbuild to quickly create a javascript bundler and enable speedy builds by streamlining the workflow. The ng build now has new experimental support for watch support, Sass, an SVG template, and file replacement in Angular 15. Now, let’s see the command for upgrading the angular.json builder is: “builder”: “@angular-devkit/build-angular:browser-esbuild”
- 16. How Can You Upgrade to Angular 15? One such durable framework that offers a variety of Angular development tools is Angular. You only need NPM installed on your system in order to install Angular 15 on it. Command to install Angular 15: npm install – global @angular/cli@latest You must enter the following command to update to Angular 15 if you are currently using version 14 or lower.
