As we are about to reach the end of 2022, there is still one more thing to look forward to for all tech professionals. Namely, Angular version 15 has finally been made available, allowing all the programmers to eliminate all those errors in Angular 14 easily. It came out on November 16th.
Angular 14 was decent, but with Angular 15, you can maintain stability, which has an added advantage in terms of making development more accessible and the whole process running smoothly.
This article covers all the features of Angular 15 in detail.
A new version of Angular is released every six months, and Angular v15 has just been released to the developer community.
The Angular v15 release contains a handful of incremental updates tailored to address bottlenecks within the Angular framework and developer pain points. This is one of the more exciting and significant updates we have seen across all the Angular versions.
Angular 15 allows a single component to work in Angular Elements, routers, HTTP clients, and elsewhere. Aside from enlarging the development process, the 'Standalone components serve as a fantastic alternative to NgModules.
When you have the reliable Angular Development company like Prishusoft, they perform the best practices to upgrade your application with latest technology and packed features.
This update brings many refinements in comparison to previous versions, namely increased stability and expanded supportability, which will inevitably elevate developer experience and performance.
The LoginService, a component within this task, contains the main logic within this program. Within the LoginService, there is only one trigger invoked to trigger the guard: the isLoggedIn () trigger within the callback function. Despite the clear structure of this code segment, many boilerplate sections should be reduced to improve their performance because it contains many boilerplate sections.
The following code can be refactored using Functional Router Guards to include all the boilerplates needed for the code to work, as presented below.
Functional Guards are compostable, which makes them the best. As a result, it can be used for creating factor-like functions, which take a configuration as input and can return a function, guard, or guard-like object that solves a concern.
The speed performance of any web application depends heavily on how quickly images load. NgOptimizedImage was introduced in older versions of the Angular framework to speed up image loading. However, it wasn't perfect. As of Angular 15, the directive has become more stable and reliable as a means of loading images.
Angular v15 is easy to upgrade, but you need to be aware of the support extensions, cancellations, and deprecations-breaking changes so that you can review and refactor your existing Angular application.
Several node.js versions have been extended by Angular v15 to extend its support for the node.js versions 14.20.x, 16.13.x, and 18.10.x version, as well as terminating support for node.js version 14.[15-19].x and 16[10-12].x.
There are currently only TypeScript versions 4.8 and older supported by Angular 15 for the time being.
Implementing Angular v15 support for your application is very simple by running the given command: ng update @angular/core@15 @angular/cli@15 from the project directory.
Using the @keyframe name format, the data can now be parsed into “@keyframes host-my-cmp_foo [... }. “
Specify a ShadowDom or None as the encapsulation view.
This rule should be defined in the global stylesheet
Create your code for this rule.
There is a possibility of triggering an error if the class contains an explicit constructor.
This update removes the enableIvy call from tsconfig.json since Ivy is only a rendering engine in this update.
As a result of the removal of canParse, parsing methods now require analyzing and hint parameters.
When RouterOutlet has completed detecting changes, it will instantiate the component.
To define the time zone, you must now use the replacement function DATE_PIPE_DEFAULT_OPTIONS instead of DATE_PIPE_DEFAULT_TIMEZONE.
Using the RouterLink directive to handle elements with href attributes is now required since routerLinkWithHref has been removed.
As well as removing some methods and directives, a new simplified syntax structure has been added to the engine. As a result, it is best to follow the Angular v14 to v15 migration guide to ensure a smoother migration.
All in all, we have covered all the new features available with Angular V15. If your business relies upon the Angular framework, then it is time for you to upgrade to the most current version of the framework. There is no way you can afford to miss out on these new and exciting features that have been added to improve the performance and speed of it and other aspects of the application.
