Angular-Based Web Development

Web development has seen changes over the past years. Back in the day, it was all about jQuery. But now, with platforms such as Angular, developers can drop runtime errors and significantly improve their performance. It’s also much easier to create professional and modern user interfaces. Let’s get into the why of it all.

Where it all began 

Released in 2010, AngularJS took the web development world by storm. It was based on three pillars:

  1. Two-way data binding: In a nutshell, whatever happens in models also happens in view. 
  2. Dependency injection: Traditionally, each object in code would have a dependency. But in dependency injection, injectors are attached to objects that link them to dependencies. These are stored in a central location. 
  3. Directives: These make it possible for HTML to make dynamic content. 

However, this wasn’t built to last. And when competitors like React came to the scene, it was time for a change. 

Angular’s release

And then came along Angular.

This framework was created in 2016, and like React, it was designed to be component-based. It no longer followed the Model-View-Controller (MVC) architecture. Components are independent features of the user interface (UI). Each has its own structure and application programming interface (API). 

Components can easily be:

  • Reused
  • Copied 
  • Replaced
  • Retested

But aside from this, what makes Angular such an upgrade from AngularJS? Well, we’ll get to that in a moment. 

But before we do, let’s examine why some developers continue using AngularJS

The great debate

While you might presume that everyone would immediately switch to Angular from the upgrade, it didn’t happen that way. In fact, to this day, nearly seven years later, many still use AngularJS. 

But what’s driving this? 

Well, it’s several factors: 

  1. There’s a learning curve: With great power comes great responsibility. And the responsibility here is learning many new architectural patterns. For many developers, sticking to the tried and true is easier.
  2. Angular frequently updates: Every six months, Google releases an update for the framework, compounding the complexity of learning how to use it.
  3. Code will have to be rewritten: Companies with applications working well on AngularJS will have no interest in making the significant investment to move forward. What’s that old adage? Don’t fix what isn’t broken. 

In summary, it’s about cost-saving, convenience, and familiarity. Change isn’t always easy.

The benefits of Angular

Okay, so now that we’ve gone over why people may not decide to switch to Angular, it’s worth going over what makes the platform great (aside from what we’ve already covered):

So one of the primary benefits of Angular is that it runs on typescript. You see, typescript has numerous upsides:

  • It captures more mistakes before production.
  • The code is relatively easy to read.
  • And it supports javascript libraries.

This isn’t even mentioning how typescript makes it easier for developers to look towards mobile development. This is because typescript is used in nativescript, which is the mobile framework for building cross-platform apps.

Along with the above, the Angular framework boasts numerous data-binding mechanisms:

  1. Unidirectional binding: As the name suggests, this lets data flow in a single direction, from the component to the view. While changes in the component will affect the view, the reverse is not true. 
  2. Two-way binding: Unlike unidirectional binding, changes in the view or the component will affect the other in two-way binding. 
  3. Event binding: The view can trigger events with the component based on events such as keyboard inputs or mouse clicks. 
  4. Property binding: This lets values from the component become bound to properties of HTML elements in the view. 

And what is the benefit of having all these mechanisms? In a word, flexibility. Developers can make use of the appropriate binding mechanism as it fits the scenario they’re in. 

(As you can imagine, all these options add to the complexity of the issues we mentioned earlier.)

Addressing the complication: documentation 

So we’ve now mentioned more than once how complicated Angular can be. 

But keep in mind Angular has plenty of documentation to get you up to speed. This includes illustrations, visual code examples, rules, and recommendations, among others. 

The open-source community is also regularly updating the documentation as per the frequent updates. 

Installing Angular 

So at this point (hopefully), we’ve convinced you why Angular is one of the must-use development tools of the present day. In this case, you will want to get ready with a few prerequisites.

Firstly, you’ll need to get yourself a node packet manager (NPM). Angular depends on this to function. 

Secondly, you’ll have to install Node.js. This server environment runs on Windows, Linux, Unix, and macOS. 

After this, you can get started with your Angular download. And the best part? It’s an open-source application that’s completely free. 

Happy coding

Overall, Angular is an excellent application that boasts a wide variety of features, and while not initially easy to use, it’s undoubtedly an excellent choice for the ambitious developer. Ensure that you take your time reviewing all the training materials available and be ready to be in it for the long haul.
