Top 10 Tips to Enhance AngularJS App Performance

Pay Close Attention To Your AngularJS Apps
Digest Cycle
The digest cycle is believed to be the most
accurate gauge of an AngularJS application's
performance. It is a looping cycle that checks
for and records any changes made to the
variables. As a result, the shorter your digest
cycle, the faster your software operates.

Put Limit On Watcher and Scope Usage
Dirty checking is a technique used by AngularJS
to track all code modifications. If two watchers
are linked, the digest cycle is run twice to
ensure that all data is updated. As a result, you
must minimize the use of watchers and scopes in
your app to increase its efficiency.
02
5
Deactivate CSS
You can utilize a directive as an element,
attribute, CSS class, or comment in AngularJS.
However, if you don't need CSS class and comment
directives, you can disable them for faster
smoother app performance.

6
Reduce DOM Access
The DOM is the heart of your application,
representing the entire ideology of page
documents. You can easily modify the page and
make performance optimization suggestions for
AngularJS using the DOM. As a result, you should
only use DOM when absolutely necessary.
04
7
Dismiss ng-model
Data is connected between the Model and View
levels using the ng-model directive. You may
reduce input bounce by using ng-model-options. It
will provide you complete control over the timing
and operation of the digest cycle for that
input. By establishing a limit, you may now
manage the length of your digest cycle. This will
significantly improve AngularJS performance and
prevent UI lags.

8
Implement One-Time Binding
The AngularJS framework offers developers the
option to connect data to an object just once.
Putting a double colon in front of the value will
enable you to achieve this. One-time binding
gives the user interface (UI) a single instance
of the object's data. It greatly improves
performance.
06
9
Rather Than Using ng-show, Use ng-if Or ng-switch
Conditionals are used extensively in every
programming language. AngularJS development
follows the same process. Developers use ng-show
to examine the specified condition and show or
hide the CSS display for that element. As a
result, the developer must use ng-if and
ng-switch to remove a superfluous element from
the DOM.

10
Utilize External Performance-Improving Instruments
We suggest you try third-party tools like
Batarang, Chrome Profiler, and Timeline to
increase the performance of your code. You may
find performance-degrading code fragments with
the aid of these AngularJS performance enhancer
tools and perhaps tweak your application to get
better overall results.

AOT Collection
The default language for Angular is Typescript.
For the browser to understand it and run web
apps, you must translate the Typescript code into
JavaScript. Angular provides the AOT (Ahead of
time) and JIT compilation options (Just In
Time). Throughout the development process, you
ought to use Ahead of time Compilation. This
technique reduces payload time and enhances
application performance.
09
12
Make Use of Lodash or Native JavaScript
The performance will be enhanced by the usage of
Lodash and native JavaScript coding. Lodash is a
JavaScript package that will rebuild the core
logic of your application. You can save time and
memory by using Lodash instead of the built-in
AngularJS functions.

Conclusion
Among JavaScript frameworks, AngularJS is one of
the most well-known. And because of this,
AngularJS has a solid reputation for producing
online and mobile applications that perform
effectively. But not everything is as perfect as
it appears to be. Since their initial release,
AngularJS-powered web applications have gotten
slower. Not to worry, though. As a seasoned
Angular development company, we have a number of
tips and shortcuts to enhance the speed and
performance of AngularJS applications. Hire
