Whats New in Angular 15?
  • 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
  • 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.

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

16
How Can You Upgrade to Angular 15?
How to Install 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 _at_angular/cli_at_latest
  • You must enter the following command to update to
    Angular 15 if you are currently using version 14
    or lower.
