Angular 15, Angular Latest Version, Released with New Features

3. Angular 15 - All you need to know about.
Angular is a popular open-source framework that has
undergone amazing changes for the current release. You
did read that correctly.
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.

7. What are the Angular 15 Features?
● 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.

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.

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
