5 AngularJS Development Best Practices

The success and sustainability of the application you develop significantly depend on the kind of development practices you employ. AngularJS development isn’t an exception to it.

Developed and maintained by Google, AngularJS is an open-source JavaScript framework that helps build frontend applications. It has modular support and enjoys extensive community support.

Based on experience and expertise, developers worldwide have come up with AngularJS best practices to help their counterparts develop incredible applications on the framework. Here are five of the best AngularJS best practices our developers have developed, basis their interactions with AngularJS development.

These AngularJS best practices can help simplify work and contribute to the success of your frontend application. Let us look at each one by one.

1. Code Writing Practices

Here are some practices for code. Use small and pure functions. Small functions are easy to test and maintain. Pure functions yield output, based on the input. They do not change the input and only deliver the output. Further, divide your code into separate modules and let every module be responsible for a single functionality. Use controller as syntax and only to make specific data available. Return promises from data cells.

2. Organizing Files

Precisely, the practice refers to structuring. When you start building an AngularJS application, you might be unsure about organizing your files or even know what files you would need.

Here, you can use the Angular-seed project, a skeleton of a usual AngularJS application. All you need to do is clone the repository and proceed. Another suggestion is using Yeoman, a tool that will create the skeleton, and add tools like Grunt and Bower.

However, before you use these tools, you must review their applicability in the context of your project. Additionally, you must consider the app’s nature to ensure you use the tools optimally and appropriately.

3. Using HTML Extension

AngularJS is not a framework to write codes that change or modify the DOM (Document Object Model). You can do it using an HTML extension, which can help you accomplish through directives.

People who have worked on JavaScript, purely or with jQuery, intend to create behavior in the DOM with the former. AngularJS offers many directives to do so. If you do not find something that fulfills your needs, you can create your directive to do the DOM manipulation. It proves advantageous, as you would have your DOM modification code in a single place, and you can unit test all your directives.

4. Checking the Digest Cycle

Let us turn to another significant aspect of AngularJS development – optimizing its performance. The digest cycle is an indicator of how an AngularJS app is performing. Additionally, it is a loop that keeps an eye on changes to monitor variables. A shorter digest cycle signifies that your app will run faster. It is vital to enhance the app’s competence, as the quicker the application responds, the more the users like it.

5. Restrict the Number of Watchers

Another crucial practice concerning optimizing the performance of your AngularJS application is limiting the number of watchers. When you introduce data-bindings, you might create more watchers and scope. However, the higher the number of watchers and scopes, the longer the digest cycle. Accordingly, and to avoid lag, you must limit the number of watchers.
