Benefits of Using Angular App Development

  • Speed

Speed is a critical factor when it comes to applications. By leveraging HTML5 features like Data Binding and Templating, the speed of loading applications is accelerated compared to more conventional MVC frameworks. 

Additionally, the use of directives for state management can significantly improve the application’s responsiveness and overall user experience. 

  • Reactivity

Angular applications utilize reactive programming to ensure they stay current with the most up-to-date features of browser technology, thereby negating the requirement for developers to continuously refresh their browsers or re-compile their code with the introduction of new functions.

  • Scalability

Angular provides impressive scalability with its capacity to manage larger applications with less likelihood of mistakes. Plus, there is virtually no need to modify views or the code base, as data changes manually.

  • Modularity

Angular simplifies app development by allowing developers to split their apps into separate components, which enhances manageability and extensibility.

  • Security

Rest easy knowing that the Angular framework is created with top-notch security protocols, ensuring the safety of your apps from any harmful attacks and data breaches.

  • Interoperability

Interoperability enables the ability to employ existing segments of your code for multiple projects, ultimately resulting in major time savings for Angular application development.

  • Flexibility

Angular is the ideal solution for creating complex apps that are simple to manage and update. Its customizable and extensible capabilities enable developers to adjust and supplement existing features to meet their needs.

10 Ways to Angular Performance Optimization Techniques

Ways to Angular Performance optimization techniques

  • Efficient Change Detection Strategies

When it comes to Angular, change detection strategy is an extremely effective tool that can assist with optimizing performance metrics. It detects new entries and updates and instantly displays the changes in the application’s view. With large and complex applications, though, the regularity of change detection can be challenging to keep up with and slow down the browser’s processes. In these instances, we can use three effective strategies to optimize the process: OnPush change detection strategy & Immutability, Pure Pipes instead of methods, and Detach change detection.

  • Code-Splitting and Lazy Loading 

When a user interacts with an application, initial load time plays a crucial role, as it directly affects the business end of the program. A delayed reaction to the user’s commands can indicate a weak load time performance.

There are many ways to increase the speed of an Angular app, including Code Splitting for improved Time To Interactive (TTI) and Lazy Loading for better program Operation. We may split our application into feature modules and load them as needed using lazy loading.

  • Utilize Web Workers to Ensure Non-Blocking User Interface

Encrypting data and resizing images are processes that, if run on the main thread, can annoy users since they cause the user interface to freeze. To prevent the main thread from becoming bogged down with these complex tasks, web workers separate them into separate threads, allowing the user interface to operate seamlessly. 

Web workers have a variety of applications, including complex calculations, real-time content formatting, progressive web apps, extensive database updates, and image filtering.

  • Optimize Events for Faster DOMs

By optimizing Events, one can avoid excessive loading and server requests. Minifying the business logic associated with events helps to expedite the DOM. When DOMs are slower, processing click events is delayed, leading to a poor user experience.

  • Optimize DOM Manipulation for Better Performance

For a high-performance application, optimizing DOM manipulation is essential. Utilizing the ngFor directive enables the successful management of multiple iterable objects. To achieve optimal performance with your AngularJs mobile app development, implementing best practices for the layout is key, as well as reducing the amount of CSS rules used. If implemented correctly, it can be a powerful tool for efficiently handling iterable objects and enhancing the performance and speed of an application.

  • Remove Unused Code Using Tree-Shaking

Tree-shaking is an effective dead-code elimination technique that can be employed to optimize Javascript code. One can eliminate all unnecessary code by utilizing Tree-shaking, resulting in a minimized build size. Interestingly, Tree-shaking is enabled by default when you use Angular CLI, and it automatically removes unused modules during build time. 

  • Remove Third Party Packages for Smaller Build

For smaller builds, Dedicated Angular Developers suggest using native JavaScript as much as possible instead of relying on third-party packages. These packages can add to the size of your app, causing it to take longer to load and reducing its performance.

  • Ensure Server-Side Rendering Using Angular Universal

The fact that over half of users won’t wait for a page to load for more than three seconds, server-side rendering is critical for web development. Angular Universal allows an application to be rendered to HTML on a server instead of the typical Angular application, which would render it on the browser.

Usually, when a user requests, the browser first displays a blank page. However, server-side rendering eliminates this problem, instantly presenting users with relevant data.

  • Use AoT Compilation for Faster Rendering Speeds

Angular provides two compilation types, Just-in-Time (JIT) and Ahead-of-Time (AoT). Before the release of version 8, JIT compilation was the only option. Now, AoT compilation has been added, resulting in significantly improved performance.

Unlike the JIT compilation, which bundles the compiler with itself and increases the bundle size, AoT compiles the program while it is being constructed and leaves out the compiler from the bundle. This leads to much faster rendering and much smaller bundle size. AOT anticipates compilation at build time and produces only the compiled templates.

  • Cache Static Content for Lightweight UI Experience

Static content caching enables a lightweight user interface for progressive web apps, making them highly successful. E-commerce customers can enjoy different platforms with a single shortcut on their home screens, avoiding the need to install a multitude of different apps while still having a native-like experience.
