The Common Challenges in Angular js Development Projects

Well Angular Js was originally developed by Misko Hevery and Adam Abrons in 2009 and is maintained by Google. Its latest version is 1.2.21. To know about the challenges faced by Angular Js, let's have a look at the basics of AngularJs, where it is used and how to learn it.

Angular js

AngularJS is a very powerful open source JavaScript framework by Google to build web applications which can be freely used, changed and shared by anyone. It is a tutorial that provides basic and updated concepts of AngularJS for beginners and professionals. The tutorial includes all topics of AngularJS such as mvc, expressions, directives, controllers, modules, scopes, filters, dom, forms, ajax, validation, services, animation, dependency injection, views, w3.css etc.

There are also AngularJS interview questions to help you better understand the AngularJS. AngularJS is a completely free open source Js, used by thousands of developers around the world and is licensed under the Apache license version 2.0.

Read our blog on “Top 6 AngularJS Best Practices and Tips”.

This tutorial is designed for software professionals who want to learn the basics of AngularJS and its programming concepts. For this you need to have a basic knowledge of JavaScript and any text editor.  It will be great if you have an appreciable knowledge in web technologies such as HTML, CSS, AJAX, etc. as we are going to develop web-based applications using AngularJS.

Benefits of Learning AngularJS

AngularJS is a framework to build large scale web applications that have high-performance and are easy-to-maintain.

• AngularJS is open source, completely free, and used by thousands of developers around the world.
•  AngularJS is licensed under the Apache license version 2.0.
• AngularJS is efficient in creating Rich Internet Applications (RIA).
• AngularJS provides developers a wonderful option to write client side applications using JavaScript in a clean Model View Controller (MVC) way.
• AngularJS can automatically handle JavaScript code suitable for each browser.

Challenges Faced

Let’s look at some of the common challenges that impede the success of the Angular app to its full potential. Our experts Angular has also found solutions to address these challenges.

• Angular Apps show Frequent Slowdown: 

From the psychology of the end consumer, it creates immense irritation when an app slows down from running out of its real pace. Naturally, the user chooses to push the app to stop or switch to another similar app.

• Unnecessary use of cloud space:

Unnecessary usage of the server causes threat to the security of any app. The security vulnerabilities in the server are the end product of various cyber attacks. It slows down the functioning of the programme.

• Slow page response of Angular app:

A slow page response makes the user click on another feature and waits, where a user’s attention span is about 5 seconds. You trade your app consumer with a rubbish answer if your app doesn’t offer what the user wants in this time bracket.

• How to Resolve this Problem? 

The best solution to tackle slow page response is to use OnPush at required locations. This will help you to optimize your Angular app’s output. If you are unable to do so, you can recruit an experienced Angular team to help you solve performance problems with Angular.

• Unexpected Crashes:

While using, the App crashes out of nowhere, leaving behind the user’s dilemma of whether to use it or not to use it. In such a scenario, you can check for a solution inside Angular instead of looking at the other best frontend structure.

How to Resolve an App Crash?

To prevent your app from such a sudden attack, you can slow the HTTP response or leverage a good service aggregator. If you can't contact any good service aggregator, you may seek consultation from an experienced Angular development company.

• Unexpected Pop-up of Errors:

Unexpected errors can now pop up due to a heavy load of data streams in your Angular app. This is the outcome of the real-time data stream that you promote to hold the attention of your end user to your app.

How to Resolve an Unexpected Pop-up of Errors?

When your app encounters such a problem, you can bring down the size of the bootstrap logic. The dilemma can be fixed in this way. Anyway, you can employ Angular programmers to support you when you are confused. An AngularJS Developer can be hired for part time, full time and scheduled time of period for your Business Development process.

Advantage of AngularJS

Since there are a lot of JavaScript frameworks for building web applications, why to use AngularJS becomes a genuine question.

• Dependency Injection

Dependency Injection is a design pattern in which components are given their dependencies instead of hard coding them within the component.

• Two way Data Binding

AngularJS creates a two way data-binding between the select element and the orderProp model. The orderProp model is then used as the input for the orderBy filter.

• Testing

AngularJS has a specific design in which we can test it right from the start. It’s very easy to test any of its components through unit testing and end-to-end testing.

• Directives, filters, modules, routes etc.

• Model View Controller

It is very easy to develop applications in a clean MVC way in AngularJS . All you need to do is to split your application code into MVC components. (Model, View and the Controller)

Model View Controller also known as MVC is a software design pattern for developing web applications. It has the power to isolate the application logic from the user interface layer and supports separation of concerns.

Model is responsible for managing application data and it responds to the requests from view and to the instructions from the controller to update itself.

View is responsible for displaying all data or only a portion of data to the users. It specifies the data in a particular format triggered by the controller's decision to present the data. They are script-based template systems such as JSP, ASP, PHP which can easily be integrated with AJAX technology.

Controller is responsible for controlling the relation between models and views. It responds to user input and performs interactions on the data model objects. The controller receives input, validates it, and then performs business operations that modify the state of the data model.
