High-performance business apps have become a reality in today's evolving technological world. The first app to come to our mind while speaking of business is Angular. Built with a superior open-source framework, all top companies prefer Angular for its fast and impactful app development for all devices. There are several ways to enhance the performance of your Angular app and you can get the support of one of the best  AngularJS app development companies in India.

Benefits of AngularJS

An open-source framework developed by Google, AngularJS is easy to learn for people with the basic knowledge of HTML, JavaScript, and CSS. Emphasising more code quality and testability, web developers prefer Angular all over the world to develop single-page applications.

Supported by a two-way data binding feature, AngularJS facilitates immediate synchronisation between the view and the model. Moreover, the AngularJS framework has a declarative UI that is understandable and easy to manipulate.

Ways to enhance the performance of your angular app

Change detection

One of the best ways to increase Angular runtime performance is change detection. One of the most common features found in JS, change detection represents the ability to detect when the user’s data has changed or altered and render the templates efficiently. However, change detection is a challenge for performing large-scale complex applications and requires a higher level of accuracy and awareness to work on the performance capability.

OnPush feature

OnPush is a change detection strategy used for detecting a value much faster when reference types are immutable objects. Used when in need of re-rendering, Angular uses OnPush to disable change detection and skip the changes in component trees when triggering is not important. Generally used to minimise change detection, the OnPush feature can manually boost performance and render the DOM.

Lazy loading

Another effective feature to optimise your browser is lazy-loading. There is a need for focussing on meticulous details that cannot be ignored while building a large-scale application. This involves loading all the feature modules but one by one instead of all at a time. By initially loading only the necessary modules, you can decrease load time as well as reduce the bundle size. As a result, you can easily boost the productivity of your module.

Using Trackby

Used for repeating over iterables and rendering a huge volume of templates, the directive helps to make an equality check run. The Trackby function helps to optimise DOM manipulation for better speed and performance. Initially tough to perform and expensive, you can better understand using simple primitives such as numbers and strings.

However, it tends to get complicated when you start to work on lists of objects. To provide a solution, the trackby function helps to extract cues from unique ID from objects for easy understanding and assess any level of changes to these objects.

Using cache static content

Caching static content is a massive success in progressive web apps that use javascript files, assets, and CSS files. With this approach, it is not necessary to install various eCommerce apps for end-users, and allows a lightweight user experience.

Moreover, you can disable unnecessary CSS classes and comment directives if they are not important for your project. You can get suggestions and improvement tips from a good  AngularJS application development company in India.

Gzip compression

Website performance is greatly affected by its page load time. One of the ways to increase the angular web app speed and transfer data quickly over the internet is using Gzip. Using fewer resources compared to other methods, Gzip compression can work with little computing power and temporary memory space. Therefore, Gzip facilitates effective compression of web pages and transferring them to high- and low-powered devices.

Ahead-of-Time (AoT) compilation

Playing a significant role in user impact, AoT compilation helps to convert Angular HTML and TypeScript code into more efficient code. This feature allows you to reduce the application of the Angular compiler and skip the compilation procedure. Accordingly, the compiled version of the application provides a faster rendering process, lowers the bootstrap time significantly, and facilitates a smooth user experience.

Server rendering

Crucial for web development, server-side rendering plays a vital role in boosting the load-time of an Angular app. It involves the process of working on the indexed pages and rendering a server despite the rendering of a browser. Being a unique process, server-side rendering involves improving the loading capacity of the pages in the browser and ranking most of the search engine results.

Optimization for improved UX

Significantly required to eliminate unnecessary loading as well as service requests, optimization of events helps to make your business logic compact. Slow DOM results in delayed processing of click events and delivers a bad user experience.

Using an Angular application called optimistic updates, it involves the update in the user interface before being saved on the server and offers a snappy native-like experience.

Using web workers

The user interface tends to get frozen due to main thread processes like encryptions of data and resizing of images. To counter this program, web workers can be used to eliminate the inclusion of the main thread in the background processes and maintain an effortless operation of UI at the same time. Some types of use cases for web workers are complex calculations, real-time content formatting, extensive data update, image filtering, and progressive web apps.

Updating third-party packages

Your Angular application requires updates for a third-party package to show effective improvement in run-time performance. Though being a small process, it is really helpful to resolve the performance issues of your application.

Conclusion

Top companies are betting on Angular to address numerous challenges associated with single-page apps, and the wave of Angular will not subside anytime soon. Through various ways to enhance performance, such as AoT compilation, runtime performance optimization, OnPush, immutability, web workers for non-blocking UI, optimistic updates for faster DOMs, load time performance optimization, lazy loading, and server-side rendering, the Angular apps can be efficient.
