AngularJS Best Practices for Building Scalable Applications

In today’s time, organizations and businesses are always wandering to create web applications that will be user-friendly as well as scalable. These web apps should be able to meet the changing expectations of customers and the standards of the market. With this vision, AngularJS has received a lot of popularity.

AngularJS is a highly popular JavaScript framework which is used for developing dynamic, interactive, and scalable web applications. It has a lot of powerful features like two-way data binding, dependency injection, and built-in directives. All these features make it a great option for developing complex and feature-rich web applications. However, as the traffic, size,  and complexity of web applications grow, the first major concern that organizations face is its scalability. AngularJS is a reliable framework that facilitates the development of scalable and responsive web applications, enhancing both the user experience and development efficiency.

In this article, we will go through various aspects of AngularJS and what are the best practices for building scalable applications.

Knowing Scalability for Applications Using AngularJS

In web app development, scalability is a crucial aspect. It is the web application’s ability to handle increasing numbers of users, data, traffic, orders, transactions, and other instances while not compromising on performance or functionality. If the web application is scalable it would be able to handle changing traffic patterns, handle large data sets, and will perform with great efficiency even during large data loads.

Why does Scalability matter in AngularJS applications?

In today’s time, everyone is equipped with faster internet connections and smoother user experiences. Thus, the users have expectations of web applications to be faster, responsive, and always up to date. Scalability is crucial because it becomes progressively more important when an application handles more users and more data. Applications that are scalable can manage the heightened volume of traffic and data loads. The apps thus provide a satisfactory user experience and the continuous availability and responsiveness of the program.

Scalability Factors in AngularJS Applications:

Several factors influence the scalability of AngularJS applications. The major factors are:

·  Data Management: It becomes difficult for an application to handle large data sets and provide real-time up-to-date data updates.

·  State Management: It is troublesome to manage complex state and data flow and leads to scalability issues.

·  Performance: It is critical to optimize performance and load times to maintain scalability.

·  Codebase Management: Managing and organizing a large codebase can be challenging and can negatively impact scalability.

You must remember that scalability is not a one-time task but a regular practice. You have to put in consistent efforts to ensure that your applications are scalable. It is a trade-off between performance, cost, and maintenance. Thus, you must know the requirements of scalability of a web application and curate the scalability solutions accordingly.

Best Practices for Building Scalable Applications:

A perfect combination of design, development, and deployment practices determines the scalability of AngularJS applications. Here are the major practices to follow for building scalable AngularJS applications:

1. Employ Modular Architecture:

A modular architecture is a methodology in which the application is divided into smaller, self-contained modules. Thus, in this approach, it becomes easier to manage and organize code. The application also becomes easier to scale. In AngularJS, there are a lot of modules that you can use to implement modular architecture.

2. Proper use of dependency injection:

By following the dependency injection approach, a class can create dependencies from external sources instead of creating them from scratch. This method will highly increase the scalability and facilitate code testing. The dependency injection technology that is integrated into AngularJS makes this technique simple to use.

3. Use automation tools and build process:

You can increase the scalability of an AngularJS web application by automating the build and deployment process. It facilitates the testing and deployment of code modifications. Angular CLI, the command-line interface, has a collection of tools for automating the development and deployment process.

4. Use of a linter and code quality tools:

The code quality tools and linter ensure that the code is written as per the best practices and with good consistency. Thus, If you hire AngularJS developers that are well-versed with this technology, they can easily manage, review, and maintain the code. This ultimately results in better scalability. AngularJS has multiple linters and code quality tools like TSLint and Codelyzer.

5. Employ Performance Monitoring tools:

The performance monitoring tools serve the purpose of identifying performance issues and related bottlenecks of the application. After fixing the performance issues, the scalability can be improved to a great extent. In Angular, you get a built-in performance monitoring tool, the Angular Augur. You can also use third-party tools like New Relic, and AppDynamics.

Common Scalability Roadblocks and How to Overcome Them?

Developing a scalable AngularJS is a challenging task. However, as we mentioned, scalability is not a one-time task but a continuous effort. Let’s know about the most common scalability challenges that you may encounter and how to overcome them.

1. Handling large data sets with real-time data updates:

The foremost roadblock in a scalable Angular application is handling large datasets and real-time data updates. Since AngularJS is two-way data binding, it could be a problem. To overcome this issue, you can use a state management library like NgRx which simplifies state management and improves performance.

2. Complex State and Data flow management:

Another major scalability challenge in AngularJS applications is complex state and data flow management. Since there is no in-built state management solution in AngularJS, it becomes a roadblock. To overcome this roadblock, you can use a state management library, such as Akita. It will help in simplifying state management and improve scalability.

3. Optimizing performance and load times:

Last but not least, optimizing performance and load times is a special scalability challenge that AngularJS apps face. Due to the two-way data binding feature of AngularJS, which can lead to performance issues, it become a major problem. You have to use process and automation tools to overcome this problem. You can use Angular CLI which improves performance and load times.
