In today’s fast-paced digital landscape, user experience (UX) is a critical factor that can make or break the success of an online platform. For entrepreneurs, ensuring a seamless and engaging user experience is paramount in retaining customers, attracting new ones, and ultimately growing their businesses.
One Javascript framework that has proven to be a game-changer in this regard is Angular, a popular front-end framework for building web applications. This article will explore how entrepreneurs can leverage Angular’s loading features to elevate user experience and gain a competitive edge in the digital marketplace.
Furthermore, you can also hire dedicated Angularjs developers and get the needed technical assistance to elevate your web app’s performance.

How Angular’s Loading Features Help Elevate UX?
Angular, developed and maintained by Google, is known for its robust set of features that simplify web application development. One of its standout features is its loading mechanisms, which are designed to optimize the loading and rendering of web pages. Entrepreneurs can harness these features to enhance user experience in various ways.
Deferrable Views for Next-Level Lazy Loading
The new Angular 17 update, up for release in November 2023, includes an extremely useful functionality of deferrable views. It is a way to make your web applications run faster.
Before deferrable views were brought into the picture, you were able to lazy load certain parts of the web page using ViewContainerRef. However, you had to manage loading errors, cleanup complexities, show a placeholder, and so on.
Managing all these aspects requires you to add some non-trivial code which is difficult to test and debug. That often led to complexities.
With the new Deferrable Views in Angular 17, you can use a single line of declarative code to lazy load parts of a web page.
@defer {
<comment-list />
}
For example, if you want to load the comment list in a blog, you can do so with this declarative piece of code. It allows you to load the comments list alongside its transitive dependencies lazily.
The amazing thing is that Angular handles all of this behind the scenes during compile-time transformation. It identifies components, directives, and pipes used within a @defer block, generates dynamic imports, and takes care of loading and switching between states.
When it comes to lazy loading a component when a specific part of the webpage becomes visible, it usually involves complex logic and the IntersectionObserver API. However, the Angular 17 new features simplify this by just requiring a deferrable view trigger, making it much easier to use IntersectionObservers.
@defer (on viewport) {
<comment-list />
} @placeholder {
<!– A placeholder content to show until the comments load –>
<img src=”comments-placeholder.png”>
}
So, for the example mentioned above, Angular initially displays the placeholder content. Angular begins loading the <comment-list/> component when this content becomes visible on the Viewport. After the loading finishes, Angular removes the placeholder and displays the component.
It also takes care of loading and error states for you.
@defer (on viewport) {
<comment-list/>
} @loading {
Loading…
} @error {
Loading failed 🙁
} @placeholder {
<img src=”comments-placeholder.png”>
}
So, these Angular 17 changes manage a lot of app complexity for you, making development easier for you.
Besides making lazy loading an easy feat, it also offers a range of triggers as mentioned below.
- On idle: Lazy loading of the block when the browser is not doing any heavy processing.
- On immediate: Begin automatic lazy loading without blocking the browser.
- On timer (<time>): Delay loading with the help of a timer.
- On viewport and on viewport (<ref>): The viewport feature also enables you to set a reference point using an anchor element. When this anchor element becomes visible, Angular will initiate the lazy loading process for the component and then render it.
- On interaction and on interaction (<ref>): It allows you to lazy load when the user interacts with certain elements on the web page.
- On hover and on hover (<ref>): This helps trigger lazy loading when the user hovers over an element on the web interface.
- When <expr>: It allows the user to specify their own condition using an expression that returns a promise.
Deferrable views also grant the capability to preload dependencies before rendering them. Incorporating prefetching is straightforward; you can achieve it by including a prefetch statement within the defer block, and it works seamlessly with all the same triggers.
@defer (on interaction; prefetch on hover) {
<app-c3/>
}
@placeholder {
<span>Placeholder (hover it, then click on it!)</span>
}
What Other Angular Features Help Achieve Faster Loading Times?
- AOT Compilation: Ahead-of-time compilation is a build process that compiles Angular templates and components during development, rather than at runtime. This results in smaller bundle sizes and faster loading times for your application.
- Code Splitting: Angular supports code splitting, allowing you to split your application into smaller chunks. These chunks can be loaded on-demand, reducing the initial load time. Code splitting is particularly useful for large applications with complex routing.
- Tree Shaking: Angular’s build tools, such as the Angular CLI, incorporate tree shaking. Tree shaking eliminates unused code and dependencies during the build process, reducing the size of the JavaScript bundles. Smaller bundles load faster, leading to a better user experience.
- Angular Universal: Angular Universal is a server-side rendering (SSR) solution that pre-renders your application on the server and delivers pre-rendered HTML to the client. This drastically reduces the initial load time, as users receive a fully rendered page. SSR improves both SEO and user experience.
- Angular CLI: The Angular CLI provides built-in optimization features and commands for generating production-ready builds. It simplifies the process of optimizing your application for fast loading and improved user experience.
Conclusion
Angular’s deferrable loading features offer entrepreneurs a remarkable opportunity to revolutionize their web applications and take user experience to new heights. As an entrepreneur, you understand that the online landscape is fiercely competitive, and user experience can be the key differentiator.
By harnessing Angular’s capabilities for faster loading, progressive web app transformation, optimized content delivery, and dynamic loading, you can create web experiences that not only captivate users but also keep them coming back for more.
In the ever-evolving world of digital entrepreneurship, the ability to provide a seamless, lightning-fast, and engaging user experience is a game-changer. Angular’s deferrable loading features empower you to do just that, giving your business a competitive edge and setting you on a path to success in the dynamic online marketplace.
So, take the plunge, explore these features, and embark on a journey to create web applications that not only meet but exceed user expectations. Your users will have better user experience and your business will thrive in an environment where user experience reigns supreme.
