Why you should use Angular for web development: Key features and benefits

Angular is now a trendy software development tool. It was introduced in 2010 and is still the most recognized name in the world of front-end JavaScript frameworks. According to the Stack Overflow Survey 2019, Angular is the second most used web framework after jQuery. What makes Angular so popular with so many web developers? In this blog, we'll discuss Angular's key features and when Angular is an intelligent choice for web development.

Angular for web development: history and overview.

Angular is an open-source JavaScript framework for creating web applications. Two Google engineers, Misko Hevery and Adam Abrons created the first version of Angular in 2009. It became known as AngularJS and was for internal applications. Soon after, in 2010, Google officially released AngularJS as an open-source framework.

AngularJS

AngularJS was a revolution in web development. Soon after its release, it gained popularity as a full-fledged front-end framework.

AngualrJS became the top choice for web applications, especially single-page applications, due to its robust tools and MVC architecture. Many leading companies such as PayPal, Upwork, and The Guardian have chosen AngularJS to build their websites.

However, the framework was unable to meet the changing needs that came with changing web development trends. So the team decided to improve the original framework and release a completely new version called Angular.

Angular (2+).

The Angular team rewrote all the code and added modern features to the revised framework. They dropped the JS suffix and released Angular 2. In this release, they gave the framework a component-based architecture and a powerful command-line interface. We will learn more about Angular in the next chapter.

Google continues to improve Angular's performance by making regular fixes. From Angular 2 to Angular 9, here is a brief timeline of Angular releases:

Why you should use Angular for web development

Choosing the right technology stack for web development requires either building your accumulation or choosing one of the commonly used stacks. Angular has remained part of popular web development stacks such as MEAN because it makes development easier for front-end developers.

As a leading web application development company, we specialize in building robust applications using the Angular framework. Our Angular developers have worked with it long enough to understand it thoroughly. Here is a detailed look at Angular's key features and how it improves web development and performance.

1. Modular design

The angular framework has a modular structure where it organizes the application code into different buckets (modules). This way, all components, pipes, directives, and services are neatly organized in separate buckets during the build.

It helps to organize the application's overall functionality into exclusive features and reusable code snippets, making it incredibly easy to share work between Angular developers.

Secondly, Angular's modular design allows for "lazy loading" of web applications. With lazy loading, the browser loads various features of the application in the background, enabling users to see and use these features as soon as they arrive at the viewpoint.

Users prefer web applications with lazy loading to those without lazy loading.
Choosing the right technology stack for web development requires considering building a custom stack or choosing one of the commonly used stacks. Angular has remained a part of popular web development stacks, such as MEAN, because of the ease of development it brings to front-end developers.

As a leading web application development company, we specialize in building robust applications using the Angular framework. Our Angular developers have worked with it long enough to understand it by heart. Here's a detailed look at Angular's key features and how it benefits your web development process and performance.

Modular structure

The Angular framework has a modular structure in which it organizes application code into different modules (buckets). Thus, all components, pipes, directives, and services are neatly organized into separate buckets as you build them.

As a result, you can classify your application's overall functionality into exclusive features and reusable pieces of code which, in turn, makes it incredibly easy to divide the work between Angular developers.

Secondly, this modular structure of Angular allows web apps to perform a lazy load. In the case of lazy loading, the browser loads various app features in the background. Thus, users can immediately see these features and use them as soon as they reach the viewpoint.

Users more appreciate web applications with lazy loading compared to those without lazy loading.

2. component-based architecture

When you use Angular for web development, you benefit from the ease of product from its component-based architecture.

The Angular framework divides an application's user interface into independent logical components, and components are organized as a tree and follow a strict hierarchy. You can compress elements with similar functionality into well-defined pieces. Because these components are independent, you can reuse the same features for any part of the user interface that requires identical functionality.

So you can easily detach components you don't want and easily replace them with other features and make maintaining an Angular application straightforward and less time-consuming.

Finally, thanks to all components' independence, you can test even the most minor parts of your application in a more organized and more accessible way.

Essentially, Angular's component-based architecture makes it easy to reuse code, maintain your application, and test as a unit. Also, new developers who join the project will have no trouble navigating and understanding your app code.

3. Angular CLI

The powerful CLI (Command Line Interface) is one of the main advantages of Angular in web development. With quick and straightforward commands, the Angular CLI automates processes such as initialization and application configuration. This automation simplifies the entire Angular web development process and improves code quality.

Using the Angular CLI, you can create new projects and add or remove functionality with a few simple commands. It also allows you to run unit tests and end-to-end tests for your application quickly.

With the release of Angular 6, the NG update command appeared in the Angular CLI, making it easy to upgrade from one major version of Angular to another quickly.

Given how much this command has liked in the ecosystem, the Angular team launched unified localization services with Angular 8, which migrated from AngularJS to Angular super fast and straightforward.

4. TypeScript

In Angular web development, code is written in TypeScript, which is the upper case of JavaScript. The main advantage of using TypeScript is that you can debug and fix code errors as you write code. It also supports types, such as primitives and interfaces, which add security to applications.

Unlike newer languages such as DART, TypeScript is not a standalone language. It is backward compatible to add functionality to your code with ES5 or a unique ECMA script.

TypeScript has built-in auto-injection libraries, so it makes code more predictable and easier to maintain. It has many other advanced tools that allow for smooth navigation and easy refactoring of Angular applications.

While most development communities prefer Angular because of TypeScript, many developers avoid using it for the same reason. TypeScript has a steep learning curve and adds to the burden of learning another language.

Most Angular developers agree that it's worth the effort, given the advantages TypeScript offers. However, if you don't want to learn TypeScript, Angular also allows you to build web applications in JavaScript.

##5. Declarative interface

One of the main advantages of using Angular for web development is the declarative interface. With Angular, you don't need to use JavaScript to define the interface of a web application. Instead, you can do it with HTML, which is much simpler than JavaScript.

HTML also brings declarative and intuitive features to Angular applications' UI components, which means you don't have to create program flows manually. You define the layout of the page and where the data goes, and Angular's declarative UI automatically loads components according to the design. This way, Angular saves you a lot of front-end development work and time.

6. Angular Universal

With Angular Universal, Angular allows you to render your web applications on the server-side instead of the client-side, which is very useful for web applications, especially for improving SEO performance.

Angular Universal provides your app with web code search, which helps your app rank in search engines. It also plays a significant role in reducing your web app's page load time and improving its performance on mobile devices.

All in all, Angular Universal is ideal for making your web app more attractive and user-friendly for users.

Should you use Angular for your next web project?

With its component-based architecture, Angular is an excellent choice for building enterprise-scale applications. Dependency injection makes it an ideal framework even for dynamic single-page applications. However, if you plan to develop lightweight or static applications, avoid Angular as it will only add unnecessary technical debt.
