Though Angular 15 rolled in with a handful of features and functionalities, let us explore some of the most effective ones.

• • Standalone API: 
  The standalone API was introduced in Angular 14, which allowed the AngularJs development services providers to build applications without using the Ng modules. However, in the latest version, the standalone API has become much more stable. They are now fully working in Http Client, Angular Elements, router, and more. The standalone API in Angular 15 allows working in synchronization with the HTTP with client routers, angular elements, etc.
• • Better Experimental ESbuild Support: 
  Well, the latest release offers experimental Sass, SVG template; file replacement, and ng build watch support.
• • Stable Image Directives: 
  The image directives feature is now stable and one of the major websites implemented the feature and observed almost 75% of improvements in LCP. By Creating secret properly, the directive makes sure that the right-sized image is requested. This in turn reduces the download time.
• • Improved Stack Traces for Debugging: 
  The core Angular team went deeper into the struggles with debugging experience. The Angular 15 offers more understandable stack errors. The version shows the error messages focused on code instead of showing issues from third-party dependencies.
• • Optimized CLI With a Bunch Of Improvements: 
  Angular CLI supports standalone stable APIs. This allows the creation of standalone components. The new version includes optimizing and configuring CLI with a bunch of other improvements ensuring better performance and reduced configuration overheads.
• • Directive Composition API: 
  This new feature gives AngularJs web development services providers the ability to add directives to host elements giving Angular a strong code reuse approach. It should be noted that this only works with standalone directives.
