In modern, fast-paced digital times, every web-based application would demand more fluency and responsiveness. For this reason, an Angular performance optimization will allow you to make your app really faster in case you develop with Angular. This article will break down various easy-to-understand strategies to improve the performance of your Angular applications.
What is Angular?
Before moving to the optimization part, let’s understand what Angular performance optimization is in a nutshell. So, Angular is one of the popular frameworks that generally are being used to develop web-based applications. It provides developers with an easy way to create interactive and dynamic websites. Like any other tool, it should be wisely used in order for the applications to keep running smoothly.
Why Does Performance Matter?
Imagine going to a website that takes an age to load or just generally feels slow. Annoying right? Users want, and indeed expect, applications to be quick, responsive, and not slow. If your application is slow, users will leave and never come back. Optimizing performance is pretty crucial in keeping users happy and engaged with your application.
Simple Ways to Optimize Your Angular App
1. Putting Analytic Into Production Mode
When you build an Angular performance optimization app, by default, it runs in a mode that’s really handy in finding bugs. The problem’s that it tends to be a little slower. By going into production mode, you’re significantly speeding things up. It turns off all of the extra checks that are useful in developmental time but aren’t needed once your app’s live.
2. Ahead-of-Time Compilation
AOT compilation is like preparing your meal in advance of serving. Instead of cooking everything once a user visits your app, AOT will compile in advance. The added advantages are that users will have a faster experience when the app loads.
3. Lazy Loading of Application Sections
Think of your app as a big book. Instead of giving users the complete book, you would just allow them to open the chapters they want to read. The technique is known as lazy loading, and it works by reducing the time taken during the initial load of the application, merely loading what is needed when users need it.
4. Do the Data Transformation Using Pure Pipes
When data is transformed in your application, pure pipes can definitely help the performance. Pure pipes run only when their input does; thus, they never perform an execution when it is not needed, and things keep smooth and efficient.
5. Change Detection Strategy: Simple is Better
Angular periodically goes through components to make sure everything is updated. Well, the thing is, this makes performance suffer if you’re working with many components. You can use an easier change detection strategy called OnPush, where you tell Angular performance optimization the checks only when certain inputs will change. That really speeds everything up.
6. Track Items in Lists Efficiently
However, regarding lists of items displaying, for example, products or messages, Angular needs to know what item has changed in order to update it effectively. You can use methods usually called trackBy whereby Angular identifies what has changed or stayed the same and reduces unnecessary updates, hence increasing the speed of rendering.
7. Async Pipe for Observables
In Angular, data often arrives by way of observables, which can be cumbersome to handle. Async pipe similarly automates subscription and cleanup of an observable on your behalf, hence making your code cleaner while improving performance by preventing memory leaks.
8. Minimize HTTP Requests
Your application communicates with a server each time it needs something from the server via an HTTP request. Too many requests will noticeably slow down your app. To improve this:
Batch Requests Wherever possible, combine multiple requests into one.
Cache Responses: responses should be cached, that is, whether the same data is needed again, it needn’t get fetched from the server time and again.
9. Tree Shaking Unused Code
Think of tree shaking as clean-out-your-closet time. You remove stuff you no longer need so that it’s easier to find what you want. In the Angular build process, tree shaking finds unused code and removes it; the files are now smaller, which in turn makes for quicker load times.
10. Optimizing Images with Other Assets
Large images can really slow down your application. To keep things speedy:
- Compressing images involves the use of tools that can minimize image size with minimal loss in quality.
- SVGs: When icons or other very simple graphics, consider using SVG files over larger image formats.

11. Cache resources using Service Workers
The service worker acts like an indispensable assistant in caching such files and data locally within users’ devices. This means that during return visits, your app will load much faster because the information does not need to fetch from the server any longer.
12. Optimizer: Cleaning Up Your Code
The Build Optimizer is a utility that takes care of the elimination of the extra parts of your code. This saves a lot of time during the build process. Cleaning up your code before it goes live makes sure only those pieces of code that are deemed necessary to make it up are what gets downloaded by the users.
13. Avoid Complex Expressions within Templates
When showing data in the templates – the visual part of your app, do not use complex expressions or functions directly in the templates. First pre-calculate the values in your component class, and then show them in your template. That’s how you avoid unnecessary calculations on every change detection performed by Angular performance optimization.
Performance to Watch
Regularly profile the performance of your application, being that optimization is often an ongoing process. Make use of performance profiling tools such as Google Chrome DevTools or Angular DevTools to figure out where a bottleneck-a region of slowdown in performance-lies and make relevant edits.
CONCLUSION: Now is Time to Take Action!
Optimizing an Angular performance optimization is not just about having things faster; it’s about creating a far more superior experience for those users that get to interact with your app daily. Techniques range from enabling production mode down to lazy loading modules. You will be well on your way to creating a high-performing application that keeps users engaged.
