The main goal of AngularJS web development is to explicate the web development process and make it an ideal software for making prototypes of other smaller applications. Furthermore, it is used in developing a Single Page Application to provide a sophisticated User Experience to the user. In other words, it makes scalable applications to 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.
ngOnChanges vs ngDoCheck
AngularJS has a watch feature whenever a value is changed. However, AngularJS does not have the watching and scoping feature 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 ngOnChanges 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.
Not unsubscribing at the right time
These continuous subscriptions lead to memory leaks in the entire system and thereby becomes a huge problem. In other words, you must unsubscribe from a service or component in AngularJS, if you are not using it.
Haphazard arranging of codes
Cose arrangement in an apt formation is one of the key components of writing the code in AngularJS app development. 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. However, you must ensure that the compact components are inside the layer of the apps.
Many times developers tend to place the additional concept into a single controller. While compartmentalizing the principle layer for the app, you must ensure that you do not use substitute ways for it. Instead of doing that, have small units organized for having a single logical layer. It will ensure your app is flexible enough, and assists in the progress of your mobile application development company too.
Involvement in jQuery
One of the customary libraries used to deal with certain events, and also make some changes and alterations to the DOM is jQuery. Furthermore, AngularJS is a platform that is used for developing scalable apps, app building, app testing. This makes it impossible for you to use it as HTML documents.
There is a section where a developer can make a mistake, and fall into an app development pitfall. The developer must have all the info about the accessible features in the AngularJS Framework before engaging with jQuery. This will help them to avoid complications related to the app-building and development process.
Making direct changes to DOM
Sometimes you need to focus on the control after a validation error occurs. Chances of making mistakes increases that time. 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 without making direct changes to the DOM.
Another common mistake that developers must 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. Tons of cross-browser tools available online 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 have a thorough examination every time.
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, complications occur while ensuring if 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.
