4 Common Bugs We Face in Angular

Angular developers regularly experience bugs in their applications, which make them revile the framework and mourn at some cryptic red lines on their consoles.

In any case, in light of the fact that Angular is fast, versatile, and optimized for different platforms, it ought not to be disappointing when utilizing it to fabricate dynamic SAP.

In this article, I will discuss four regular causes of Angular bugs and defects and how to avoid them (like the plague!).

1. Confusion in Terminology:

Angular, which as a rule refers to Angular v2 or more, ought not to be mistaken for its predecessor, AngularJS.

Angular does not simply refer to another version of AngularJS; it is a revise of the first framework.

Presently, AngularJS refers to version 1 of the framework. Also, the later versions, from version 2 on, are called Angular without the "JS."

This disarray in terminology frequently causes developers to lose and confound the execution of concepts when building applications utilizing the framework, particularly while working together in a group.

In this way, to keep away from Angular bugs, you have to know the version you are managing.

2. Utilizing Modules Incorrectly:

Angular modules, called NgModules, are what enable you to compose your application to such an extent that it can understand your objectives—from start to finish.

In any case, if not utilized well, these modules can be a wellspring of grief that can handicap your development efforts.

From the beginning, you ought to make a root module. This module serves the basic job of pulling together alternate modules, as your app keeps on developing.

In the event that you do exclude it, consolidating extra highlights a short time later could be dangerous and mistake inclined.

Besides, as your app develops, you ought to guarantee you just import the privilege and vital modules.

Bringing in modules you don't realize well will expand the bugs in your application.

3. Inappropriate Naming:

Angular developers who don't hold fast to appropriate naming practices frequently make mistake inclined and hard-to-debug applications.

In the event that you pursue the right naming traditions, you'll reduce naming conflicts, conflicting references, and inefficient coordinated effort.

Here are a few things you can do to keep off naming-related bugs in your Angular applications:

Name folders and files to exhibit their utilization, without a second a speculation. For instance, app/users/users-list.component.ts might refer an app part that deals with a rundown of users.

Utilize a predictable naming approach all through your Angular app. For instance, you can utilize a procedure that first names a segment's component trailed by its sort (feature.type.ts, for example, naming a file app.component.ts.

When naming classes, utilize the customary upper camel case. Along these lines, it shows that the classes can be instantiated and built as cases.

4. Directly Mutating the DOM:

Another basic bug that plagues Angular applications is straightforwardly mutating the DOM.

Other than being viewed as an awful practice, this misstep can likewise make your Angular app run bleakly in platforms other than the program.

The getAngularBugs work exhibits three different ways to collaborate with the DOM specifically: utilizing jQuery, ElementRef.nativeElement, and the worldwide report protest. In any case, that approach makes your app vulnerable to errors.

To change the DOM in Angular and maintain a strategic distance from errors, utilize the Renderer2 benefit (accessible in v4 or more).

The Renderer2 accompanies different strategies to change an element, much the same as the JavaScript DOM API.


The article exhibited four of the most widely recognized issues Angular developers experience while making their applications.

As an Angular engineer, you ought to always gain from your programming botches and abstain from rehashing them in future.

Furthermore, always enhancing your abilities utilizing practical projects is the most ideal approach to guarantee that bugs don't find you napping, regardless of whether you are a prepared designer.

Happy bug-free Angular coding!
