Angular 15 New Features and Improvements for Developers

Angular 15 New Features and Improvements for Developers

 

Introduction

Angular 15 is the latest version of the Angular framework, released on March 8, 2023. This version includes several new features and improvements that enhance the usability, performance, and scalability of applications built with Angular. In this blog, we’ll discuss the updated features and developer tools that developers can leverage for their projects.

 

1. Standalone APIs

Now it is possible to develop applications without NgModules. Components can be used in any Angular application without being part of a module. The standalone API allows developers to bootstrap applications using a single component.

2. Router and HttpClient Tree Shakable APIs

Angular 15 introduces enhanced tree-shakable APIs for both the router and HttpClient, allowing for better optimization and smaller bundle sizes, providing developers with powerful developer tools for more efficient application development.

 

3. Directive Composition API

The directive composition API enhances code reuse significantly. This feature only works with standalone directives, providing developers with new ways to compose functionalities using advanced developer tools for greater flexibility and efficiency.

 

4. Image Directive is Now Stable

The NgOptimizedImage directive simplifies performance best practices for loading images.

It allows for the automatic generation of srcset attributes, making it easier to fill parent containers without needing to declare the image’s width and height.

5. Functional Router Guards

With tree-shakable standalone router APIs, boilerplate code in guards has been minimized, simplifying the implementation process.

6. Router Unwraps Default Imports

To simplify and reduce boilerplate further, the router now automatically unwraps default exports during lazy loading.

With the new code structure, developers can expect a more streamlined coding experience.

7. Better Stack Traces

Angular 15 improves debugging with enhanced stack traces, making it easier for developers to identify and fix issues.

 

8. More Improvements in Components

There is support for range selection in sliders, and further enhancements have been made to the experimental ESbuild support, enabling faster and more efficient builds. Additional improvements include automatic imports in the language service and CLI enhancements.

Conclusion

Angular 15 represents a significant upgrade with numerous new features and improvements designed to enhance usability, performance, and scalability. Notably, it offers improved security features, making it easier to implement encryption for protecting sensitive data in applications. Developers using Angular should consider upgrading to the latest version as soon as possible to take advantage of these advancements and explore the enhanced developer tools that streamline the development process.
