use Angular for web application project

Firstly, Thank you for landing upon this page and trusting us that we can provide you enough information about Angular, which other articles may have failed. In this blog, we are going to discuss the Angular and its journey so far. We hope this article makes you well-versed with the Angular introduction, its advantages, and some practical uses of Angular. If you have a project idea in mind, but are confused whether to use Angular or not for app development, then you need to read this blog.

Novice developers are excited to learn Angular and gain enough experience in Angular app development, while most of the startups and company’s CTO are getting inclined towards it. Angular needs no introduction; it is the most versatile and treasured framework in today’s time. It has many brilliant support factors that it is used to develop interactive web applications for mobile devices as well as desktop.

Angular is the best framework in the JavaScript ecosystem, which is used to build some ingenious applications. It is an open-source front-end framework that is developed by Google to build dynamic web applications.

Angular was first introduced by Google engineers, Misko Hevery and Adam Abrons, in 2009 as AngularJS, and since then, various updated versions have been released. Today, we have Angular version 9, which was recently debuted in February ’20. And with every update, Angular development just becomes better and more efficient.

The 2018 Stack Overflow survey counts Angular as the second popular framework used after Node.Js. The top reasons why it is favorite are, it is a robust tool for app development, and it assists developers in writing readable, maintainable, and easy-to-use code.

It is a built in TypeScript and helps in developing client-side web applications. Due to the increasing popularity of SPAs, developers are inclining more towards this framework.

Data-binding, simplified MVC pattern, Cross-platform development, Speed and performance, Flexible development, One-page application, simple & expressive, modularization, AJAX handling, RESTful API handling, etc., Angular has it all. These features are quite compelling, isn’t it?

Additionally, you do not have to rely on third-party libraries while using Angular. Well, with brilliant other players like React, Vue, and Ember frameworks in the market, you may ask why Angular only then?

Here are a few proven reasons Why Angular is the winner of all of them. Find out the strong points about Angular in the next section.

Google Supported:

It is a blessing in disguise for the developers to find out that Google supports Angular. Google’s support for the platform confirms that Angular is trustworthy, and Google will keep on upscaling the ecosystem.

Google’s Long Term Support (LTS) reconfirms that the team is optimistic about Angular, and the framework is here to stay for long.

Detailed Documentation:

What could more a developer have asked for if they can find a solution to each query? Yes, Angular is highly popular for its exhaustive documentation, where a developer can find any information related to the development.

Declarative UI:

Angular uses HTML for UI designing. HTML is a go-to language for developers and is declarative and intuitive in itself. So wonder how does this help? Well, while using HTML for Angular, you do not have to decide the flow; instead, you just have to define what all you need and rest will be handled by Angular.

Perfect ecosystem for third-party components:

Developers wish to add hundreds of features and functionalities in the web app built with Angular. And to do this, they need additional tools and third-party components. Angular extends its support to all these tools and components using which you can build a unique application.

TypeScript:

Angular web apps are built using the TypeScript language. TypeScript is a superscript of JavaScript and more secure than it. TypeScript is capable of finding and eliminating errors made while typing the code.

It highly relies on JSES6, and hence, a developer doesn’t have to learn a new language altogether. But, Angular definitely gets more advanced features like static typing, interfaces, classes, namespaces, etc. TypeScript also improves navigation, refactoring, and auto compilation services.

Component-based architecture:

With regular Angular updates, it moved from MVC to a component-based architecture. This means the app structure can be divided into independent logical and functional components.

This makes it easy for the developers to organize, segregate the components, and also reuse them later. The components can easily be decoupled, tested, and project development can be carried out seamlessly.

POJO (Plain Old JavaScript Object):

It comes as another surprise that you do not have to use any additional getter or setter functions while using Angular. The reason being, Angular facilitates all the conventional JavaScript functionalities, and every object uses POJO. This means you can easily manipulate the object by adding or removing the properties from it.

Ahead-Of-Time (AOT) compiler:

The AOT compiler converts Angular’s TypeScript and HTML into JavaScript right at the initial stage of the building process. Hence, the project code is compiled and loaded at a nimble speed. Additionally, the AOT compiler is more secure than a Just-in-Time compiler.

Ease of testing:

Since the whole web application is divided into parts, aka components, you can automate testing for each part of it. Also, you do not have to remember the order of testing, just follow, “one-file-one-module” principle.

Code Consistency:

As much as it is important for a content writer to maintain consistency in the flow of content, it is equally important for a developer to maintain the code consistency while developing a project. Any inconsistency can increase the risk of delayed launches or an increase in the development cost. Since Angular relies heavily on component-based architecture, every line of code begins with the same style.

Angular CLI:

The command-line interface tool is used to initialize, develop, scaffold, and maintain the Angular application. It automates the angular development workflow, which further enhances the code quality. Using Angular CLI, it becomes easy for you to create a new Angular project, add features, run unit testing by writing a few lines of code.

Angular Elements:

Angular version 6 and onwards allow you to add custom elements to the web applications built with React, JQuery, or Vue.

Ivy Renderer:

Angular 6 seems to have changed the game. This is another great feature that became available after Angular 6. Ivy Renderer’s role is to interpret the Angular components and templates into JavaScript, which can further be visible on a browser. The tree shaking technique removes unnecessary code, making the codebase smaller and clear.

Dependency injection:

Dependency injection means one object supplying dependencies of another object. The ultimate benefit of having dependency injection is that if you make changes in any part of the code, it will show how other parts are affected by the change. This also makes the code readable and maintainable and saves a lot of time while testing.

However, it is difficult as well as time-consuming to create dependencies for the components.

Ease of Maintenance:

Angular app’s components are decoupled and replaceable. Which means it is easy to update and maintain the code for better.

When to use Angular

Angular Universal:

Angular Universal provides ample benefits for project development. It is primarily used for server-side rendering and makes it easy for the search engine bots to crawl your web app. Additionally, it decreases the page loading time, thereby improving the performance of apps on mobile phones.

This all being said and written, Angular is not perfect. It has its loopholes, which can be a barrier for app development. Let’s find out the weakness of Angular.

Difficult to learn:

Angular is difficult, specially for a newbie developer; it is a strenuous job to learn Angular. The component-based structure is easy to understand, only if you have prior experience in dealing with it. A newcomer may find it hard to manage and set the dependencies.

Poor SEO:

Many developers still have complaints regarding the search engine bots’ inability to crawl through the web pages. No doubt that the entire Angular team is working behind making the Angular apps SEO-friendly, but it looks like they need to make a little more effort in doing so. Since the SPA content changes quite frequently, web crawlers are unable to identify the change, which further affects the web app’s indexing.

Difficulty with backward compatibility:

This weakness can definitely be overlooked because you can easily migrate backward, i.e., from Angular’s fifth version to the fourth version. But, the problem is to move backward from Angular to AngularJS.

As you can observe, the benefits overrule the weaknesses, and hence, many businesses opt for Angular for web application development.

When to use Angular

Here are some businesses that would make the most of the Angular Web App Development.

Progressive Web Apps:

Progressive web apps are changing the dynamics of application development, and it looks like they are here to stay for long. It was first developed by Google in the year 2015, and the Angular version 5 released after 2015, has built-in PWA support. It looks like Angular holds a real potential to build a dynamic Progressive Web Application.

Enterprise Web Apps:

As we all know, Angular is based on TypeScript, which comprises all the features that are required to build an enterprise web application. As mentioned above, the advanced refactoring, navigation, autocompletion, etc., make the process easy.

Apps with dynamic content:

Angular lays the grounds for Single Page Applications. It is ideal for the projects where the content changes dynamically as per the user behavior and movement. Additionally, the dependency injections aid in changing the response of connected components.

Some of the admired apps built using Angular include,

YouTubeTV

Crunchbase

Aiesec

Blispay

NBA.com

For which projects you should not use Angular?


Many times, Angular puts an extra burden on the projects for which it is not suitable for. Hence, you should not use Angular if you are planning to develop a project related to the below-mentioned cases.

SEO-optimized websites:

Angular is not SEO-friendly unless you make additional efforts to optimize the apps developed with it. Hence, if your aim is to top the search engine results, then Angular is not recommended.

Short-term projects:

Project development with Angular should not be preferred if you are tight on budget & resources. It is difficult to learn and manage the framework with a team of few developers.

Apps designed with the microservice approach:

Angular is not preferred for applications with a microservice architecture because it doesn’t give you flexibility in terms of tools selection.

Lightweight apps having static content:

If you use Angular to build small websites with static content, it will only add to the complexity, thereby increasing the load time. Hence, do not use Angular for such projects.

Summary:


Angular provides multiple & significant benefits for a fully-fledged web application development. Hopefully, you are clear with the features and concepts of Angular and how it will assist you in building a robust application.
