Common Mistakes That Should Be Avoided When Using AngularJS Web Development

The main goal of AngularJS web development is to explicate the web development process that makes it an ideal software for making prototypes of smaller applications. Furthermore, it is used in developing a Single Page Application that can help in providing a sophisticated User Experience to the user. In other words, it makes scalable applications that can be used on multiple devices.

And if you want to reap the maximum possible assistance from this scalable web software, you should steer clear of the below-mentioned booby traps.

Today, in this blog post, we will talk about the top 7 common mistakes that AngularJS developers should avoid while developing a web application.

  1. ngOnChanges vs ngDoCheck

AngularJS has a watch feature whenever a value is changed. However, AngularJS does not have this feature of watching and scoping anymore, and some components are input as the properties. Apart from that, we have the non-changes lifecycle hook from AngularJS Web Development.

For improving run times, the event of OnChanges does not change every time there is an input property changed in the deep field. When developers are unaware of this format, they fall into the booby trap quite easily.

  1. Not unsubscribing at the right time

If you are a member of a team of AngularJS developers in an AngularJS Development company, then you cannot have an excuse for failing to unsubscribe. For AngularJS Web Development, you have to clean up all the subscriptions made. After completing the use of an event or observable in JavaScript, you are required to contemplate the existence of various strategies and libraries which have been built to deal with these acts of not unsubscribing.

These continuous subscriptions lead to memory leaks in the entire system and thereby become a huge problem.

In other words, you are supposed to unsubscribe from a service or component in AngularJS, if you are not using it.

  1. Haphazard arranging of codes

One of the key components of writing the code in AngularJS app development is to arrange the code in an apt format. Usually, you are required to have a Controller for the View when you are working with the MVC. This controller will be the principle layer that you will use, and you are required to make sure that there are compact components inside the layer of the apps.

Developers tend to make one common mistake, and that is, placing the additional concept into a single controller. When compartmentalizing the principle layer for the app, you must ensure that you do not substitute ways for it. Instead of doing that, you can have some small units organized for having a single logical layer.

Since we have demonstrated the fact that you need to segregate the code, you will be able to see that with the help of prices and compartmentalized code, you will be able to make sure that your app is flexible enough and assists in the progress of your mobile application development company too.

  1. Involvement in jQuery

One of the customary libraries used to deal with certain events and also make some changes and alterations into the DOM is jQuery. Furthermore, AngularJS is a platform that is used for developing scalable apps, app building, app testing, so this makes it impossible for you to use the HTML documents.

Here is the section where you are making a mistake and falling into an app development pitfall. A developer needs to have all the info about the accessible features in the AngularJS Framework before engaging with jQuery. This is one of the most essential things that a developer has to consider if he/she wants zero complications in the app-building and development process. 

  1. Making direct changes to DOM

Many a time, developers tend to make some direct changes to DOM. These changes are made using the controller, which is one of the problems. However, altering the DOM is required to operate the platform of JavaScript. But, if you do so, you have to refresh the title of the page according to the change in context, or you just have to execute SVG. There can also be a situation when you have to place your main focus on the control after a validation error occurs.

The possibilities are endless. If you encounter such problems, you need to use jQuery since it is a global object. You can also use Renderer2service. In this way, it will be easier for you to manage and not make direct changes to the DOM.

  1. Examination failure

Another common mistake that developers need to avoid is not examining your app before launching it. This will cause some bugs to creep in, and eventually cause the application to malfunction. Thereby, affecting the app’s performance. There are a ton of cross-browser tools that can be used to examine the application for potential bugs before launching it.

Well, we aren’t advising you to test every single environment with the OS but you can always have a thorough examination.

  1. Settled Scope Binding

AngularJS has an entire framework that consists of many scoping principles. Let’s look at an example to make it clear for you. A mishap can be caused in the specific binding system due to the restrictions AngularJS has on the easy application of various sources of data on any particular model.

However, these complications are caused to ensure the names used are properly overhauled. Value passes primitives and reference passes non-primitives in the case of AngularJS Web Development. To fix this issue, you are recommended to assemble all the objects of scoping in an accurate and right manner.
