Developing Your First AngularJS App – 5 Expert Tips You Need

For a considerable time, developers relied on JavaScript for front-end development. Now that technology has evolved with advancements and modern architecture. As a result, the new backbone of front-end development is AngularJS.
Being an extension framework of JavaScript, AngularJS has become the need of the hour for businesses. Without this heroic framework, one cannot imagine developing Single Page Applications (SPAs). Since more and more enterprises are looking to hire Angular developers. You can employ Angular developers and come up with a business solution. However, they need a comprehensive guide to some of the best Angular practices in development. These tips and techniques will not only help you improve the coding. But will also ease the burden of maintaining it.

So, let’s try adopting some of the expert’s secret Angular development tips for a smoother run without any further wait. Oh, wait! Before we start, we should also glance at AngularJS for business.

What is AngularJS?

AngularJS is an open-source JavaScript MVC framework created by Google. It is one of the most popular platforms for developing dynamic and efficient client-based web applications, structures, and modules.
Due to the MVC (Model View Controller) model of Angular, many enterprises find working with the framework challenges. But for powerful syntax and functionality. One must try learning about modern frameworks and tools. So, if you are new to Angular tools, here are some development practices to increase your expertise in managing your upcoming Angular projects.

1. Redrafting the default directory structure-

AngularJS enables the restructuring of the default directories. How? It gives you the fault directories based on the size and type of application you are working on. In addition, you get available options for services, templates, models, controllers, and other objects for locating directories with specific modules.

But if your application becomes more extensive, you will have to manage many files. Further, finding specific modules for these directories might also become tiresome for you.
This is why large data files need to group into logical sections with Angular restructuring. You can take a look at the below sample structure for large projects.
app/
app.js/
dashboard/
frontpage.html/
FrontPage controller.js/
frontpageservice.js
order/
order.html
ordercontroller.js
orderservice.js
As you can see, there are different locations for the front page and order components in this structure. Therefore, even if these components break in the future, you can still identify them in the directories.

2. Presentation out of Controllers

If you hire AngularJS programmers, ensure that they do not manipulate the presentation logic in DOM (Document Object Model) structure. This will end up getting malfunctioned in the MVC structure.
AngularJS is based on the MVC structure, where each module gives a separate model. The presentation logic is coded in the View structure, so if there are any changes to make in the HTML element. Ensure that the presentation layer is not interrupted.
If you keep the presentation in the Controller, it might break the layer. So whenever the developer misses any code inside the controller, it results in a bug. Hence, the best hack is to keep the Presentation logic out of the Controller.

3. Using trackBy function-

One common practice in Angular developers is to create lists from Objects in AngularJS. Unfortunately, this makes the code less dynamic and efficient when put in the DOM structure. Although we cannot avoid this process, the number of times your code interfaces can reduce.
Using the “track by” function in your code limits the number of times a list is re-rendered. If you look at the syntax below, notice how the list is re-rendered every time in the DOM.
<div ng-repeat = “list item in Order List”>
</div>
Except, the more convenient method of writing this syntax is:
<div ng-repeat = “list item in order List trackby item.orderid”>
</div>
Here, the second block of the code “item. Order id” helps simplify the process by allowing only one key at a time to generate unique IDs. This is how the item “trackBy” can save you.

4. Injecting Dependency

Dependency injection is a process of disassociating several elements from the application to the main logic. This injector helps modify the core logic without disrupting other aspects of the application.
A dependency injection looks like this in AngularJS:
angular.module(‘YourAppName’).controller(‘YourControllerName,’[‘$scope’,’YourServiceName’,function($scope,YourServiceName){//Controller Code goes here
}
]);
You can change your core logic using the above syntax without affecting other services. This trick is best suited for enterprise-level applications where code changes are often required.

5. Using Specialized Angular tools:

Testing any application or software is crucial since it includes the performance results and future success rate. There are many testing tools available in the market. But, we would recommend using the specific tools ideal for Angular applications.
Angular is an updated and modified version of JavaScript that asks for tools dedicated to debugging the code, reviewing performance, and identifying bugs and errors. In addition, you can consider the ng-inspector extension from Google Chrome. Some other tools can be Mocha, Jasmine, and Protractor.

Wrapping Up!

The above five Angular development practices might not solve all your queries and challenges but can be helpful for a smoother developmental run. Using these tips, you can set up a good foundation for your AngularJS application and avoid frequent issues for more insights on well-structured applications. You can hire Angular developers and come up with a business solution.
