What’s New in Angular 15?
Angular 15, Angular Latest Version, Released with New Features
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.
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.
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.
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.

● 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.

● 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();
}
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.
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.
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.

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.
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.
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”
