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.

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.

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
• Its 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.
• _at_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 () gt inject(LoginService).isLoggedI
  n()
• 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.

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, lets see the command for upgrading the
  angular.json builder is
• builder _at_angular-devkit/build-angularbrowser-
  esbuild

16
