In order to manage the decreasing attention span of people on their screens around the world, developers need to make faster and more responsive applications.
So naturally, if you do not improve the performance of your application, you will probably lose significant traffic and suffer huge opportunity losses.
With this blog, we want to bring the solutions for managing an Angular front-end and talk about how the performance and hence the viability of an app built with AngularJS can be improved.
Most Common Performance Issues in Angular Apps
Angular apps have a lot of performance difficulties. The following are a few of the most important:
- Memory leaks: Memory leaks occur when circular references are used. This occurs because Angular must keep track of all references in order to remove them; yet, if we do not remove them, the app will continue to expand and eventually crash.
- Too many watchers: Watchers are used to monitor changes, and having too many on an object or property might cause performance concerns.
- Excessive DOM manipulation: While Angular strives to change the DOM as little as possible, there is a limit to how much it can do without negatively impacting performance.
- A large number of bindings: When we attach an event handler, it creates a binding, which means Angular has to do additional effort to establish another binding.
Why There’s A Need for Performance Optimization for Angular Apps
An important aspect of web development is performance optimization. This is a process that requires constant vigilance and attention to detail. For Angular apps, this is necessary because Angular has a lot of features and should be optimized to provide the best user experience.
It’s critical that your app is quick and responsive so that consumers don’t have to wait. By modifying the code and reducing unneeded weight from the browser, the optimization process achieves this.
Best Practices for Improving Angular App Performance
Here are a few suggestions for enhancing the performance of your Angular app from the industry’s best angular js developer.
Utilize the AoT Compilation
The advantages of AoT compilation are as follows:
- Improved user experience through faster performance
- Improved SEO performance
- Memory usage is reduced
Lazy loading is an optimization approach that allows content to be loaded only when it is needed. It’s done to speed up the app’s initial load time and improve its overall performance. This strategy is used in mobile apps to improve overall performance and user experience.
Some of the benefits of slow loading:
- Before interacting with the content and receiving relevant responses, the user does not have to wait for all of it to load.
- Users will feel more comfortable with an application if they can interact with it sooner.
- Lazy loading decreases server requests, resulting in improved application performance and lower data consumption.
- The user only downloads what they require, conserving bandwidth and device storage space.

Assets are being compressed
If your Angular app is slow and you want it to run faster, make sure the assets are compressed. Assets can be compressed by minifying them (removing any extraneous characters) and combining them into a zip file. The smaller an asset file is, the quicker it will load.
Server-Side Rendering is a safe bet
One of the most prevalent approaches for enhancing the performance of web applications is server-side rendering. Before any browser queries are made and transmitted to the client, an HTML document is created on the server using this technique. This results in a faster reaction time & avoids some of the problems that come with traditional browser renderings, such as blank screens and long page load times.
This approach has been around for a while and is utilized by a number of organizations, including Facebook, Twitter, and Google. It’s more than a buzzword or a fad; it’s a technology that has been shown to improve the performance of online apps.
The goal of tree-shaking is to get rid of code that isn’t being used by the application. You can shrink the size of your software and increase its loading speed this way. Tree-shaking provides a distinct function for each language to accomplish this.
The best part about Angular is that tree-shaking can be done directly from the CLI.
DOM Elements that have been reduced in size
The Document Object Model (DOM) is the browser’s representation of a web page’s content and structure. It can cause performance concerns for websites if it isn’t optimized. The number of DOM elements in an application is frequently reduced by app developers. Because DOM elements are large and slow down the program, this is the case.
Reducing the number of DOM elements can help with performance and memory utilization. It can also speed up the loading of your website and reduce the amount of data carried over the internet.
Make Use of Caching Options
When a page takes time to load, users become annoyed and leave. We can lower the load time of an Angular project and make it more user-friendly by caching resources.
Caching is a technique for storing data or information in order to retrieve it more quickly in the future. It might happen locally on a computer or remotely on a server. By storing resources locally and retrieving them when needed, this strategy decreases load times. With the use of Angular’s built-in service named $http configuration and object to true, we may cache resources in Angular apps.
This will make parsing and execution considerably easier for browsers, potentially resulting in quicker performance.
So there you have it: the most important Angular app performance tips and strategies. If you stick to our recommendations, you’ll be able to significantly improve the speed of slow Angular apps.
