Developed an impressive Angular application but are not able to use it to its full capacity? One possible reason for this is the sluggish performance of the app. When an Angular app or any other app, for that matter of fact, is slow like a snail, its users have endless hassles.

In this crisp post, you have a chance to get familiar with a few tried and tested tips that will help you improve the performance of Angular application in a blink of an eye.

Start Booting the Performance of Your Viable Angular Application

Below-mentioned tips and tricks are here to make sure that your Angular application is as fast as Cheetah. So, check them out today.

#1 — Try AOT Compilation

If the concerned app is slow at the beginning and maintains a sluggish speed during runtime, you must try AOT compilation. Unlike another compilation method, Just-in-Time compilation which happens when a problem occurs, AOT compilation takes place just before the application runs. This way, it’s more effective.

#2 — Lazy Load Modules

Get rid of load time laziness of the application with Lazy Load Modules. In this technique, the application is divided into multiple small modules and loads only crucial modules. This way, the application doesn’t have to waste time loading modules that are not needed.

#3 — Change Detection Optimization

The smart Angular developer is the one who knows what it takes to optimize the change detection mechanism. It’s a resource-intensive feature exerting a great burden on the app. So, optimize it with actions like not using two-way data binding excessively, using unidirectional data flow, and OnPush change detection technique.

#4 — Go for preloading

Preloading is one of the most convenient ways to optimize the Angular app as it makes frequently accessed resources preloaded so that they are easily available for future use. This is already a part of Angular’s router modules and helps in the easy loading of routes and modules.

#5 — Production Mode is a savior

Don’t want to invest much effort in debugging and optimization? Try production mode that automatically disables a few debugging features and optimizes the concerned app.

#6 — Have a hold over network requests

One viable tip for Angular app optimization is reducing the number of network requests.

You can use caching, compression, and minification techniques for this.

#7 — Go with pure pipes

Pipes are the key components of an Angular application, as they are crucial for transforming dates, currency, and strings. While you’re planning to use pipes, make sure that you’re picking pure pipes, as they have no downsides, and their inputs are easy to cache. This way, they are not too heavy and consume more CPU space.

Final Say

All the laudable features of an Angular app will seem useless if it’s not performing at optimal speed. Hire a skilled Angular developer and try these tips to make sure that your app has blazing speed.
