Angular, the renowned open-source web application framework developed and maintained by Google, has long been a go-to choice for developers seeking a robust and scalable solution for building dynamic and feature-rich web applications.
The release of Angular 17 has once again opened a new door for web development, offering a wealth of exciting new features and improvements that enhance the developer experience
Angular 17 major advancement is toward crafting high-performing and user-friendly web apps. With a fresh look and feel, Angular 17 brings improved performance, efficient developer experience, and much more. This blog explores all the latest improvements and features of Angular 17.
8 Key Features and Improvements of Angular 17
New Angular 17 features include streamlined component architecture, improved performance, and a renewed focus on accessibility. The advancements and renowned power of Angular 17 make it a compelling choice for those looking for a robust web development experience.
1. Typescript 5.2
The latest version of Typescript comes with a lot of new features that help with optimizing AngularJS performance. Angular 17 embraces TypeScript 5.2, which brings improved type-checking, modern language features, and enhanced type safety to Angular projects. This integration helps catch errors earlier in the development process and enables a more robust codebase.

2. Deferrable Views
The latest Angular 17 features come with deferrable views which enhance the performance along with the coder’s experience. The deferrable view helps to load and render components when required.
Now this helps delay the loading of sections that are not required by the user for example a sidebar or comments section, hence the faster loading time initially boosts the performance. Using a declarative and user-friendly approach, deferrable views streamline the process in contrast to earlier methods that depended on ViewContainerRef for lazy loading.
3. Support for View Transition API
Several browsers, including Chrome, Opera, Chrome for Android, Edge, Samsung Internet, and WebView for Android, support the View Transition API. Typically, utilizing this feature requires a combination of CSS and JavaScript.
However, with the launch of Angular 17, there is now an opt-in support option available. This Angular 17 feature, simplifies the use of the View Transition API, eliminating the need for complicated coding.
4. Server-side Rendering
There is a remarkable improvement in Server-Side Rendering in Angular 17. Angular 17 brings stable SSR integration while providing a lot of benefits like reduced build duration, better rendering, and enhancement in SEO suitability.
With the SSR improvements, it lets you make sure that search engines can effectively crawl and index the content of your app, ultimately improving the discoverability of the app. Moreover, it contributes to quick page loading helping to maintain user interaction with the web.
5. Built-in Control Flow
Angular has introduced a new way of writing control flow directly into the template. This new syntax eliminates the need for directive-based control flow like ngIf, ngFor, and ngSwitch. The new control flow syntax provides powerful features and declarative APIs.
Simply it allows programmers to write and manage code effortlessly similar to other programming languages like JavaScript and Python. These improvements not only help build end-to-end code but also enhance performance.
6. Reduced Memory Usage
Angular 17 introduces optimizations that can lead to up to 30% less memory usage. This is achieved through more efficient content rendering and better cleanup of unused resources, allowing applications to handle more users without performance degradation.

7. Faster Application Start and Build Times
Angular 17 leverages ESBuild, resulting in over a 67% improvement in build speed compared to previous versions. This allows applications to be ready for users much quicker, enhancing developer productivity. Moreover, the apps can start over 50% faster which enhances user experience right from the initial load.
8. Standalone Components
Angular 17 introduces standalone components. These components operate independently of the conventional module framework, enabling greater flexibility and enhanced reusability. For instance, you can develop a reusable login component that can be seamlessly incorporated into any section of your app without having to craft a dedicated module for it.
Standalone components allow developers to concentrate on the main purpose of their components without having to worry about NgModules. This makes the code cleaner and easier to manage.
These features surely make Angular 17 a powerful entity, focusing on improving developer productivity, enhancing performance, and providing a more flexible framework for web app development.
