When creating apps for mobile and desktop platforms, Angular is a top choice for many developers. Its popularity among front-end and back-end developers has skyrocketed since its 2016 debut.
It has cutting-edge features that improve code organization and productivity. Business owners and managers should be aware of and prepared to implement the steps necessary to transition from AngularJS to Angular.
Angular Vs. AngularJS – The Main Difference
The primary distinction between Angular and AngularJS is the scripting language upon which each is based; Angular is written in TypeScript, whereas AngularJS is written in JavaScript. These two front-end open-source frameworks share many commonalities in developing dynamic web apps and SPAs.
Why Migrate from AngularJS to Angular- Top Reasons
Remember that the two frameworks are very different; Angular is not an updated version of AngularJS. However, this fact alone does not fully explain why some developers have made the switch. Below we have enlisted some reasons why AngularJS to Angular migration is essential.
Structure Design
Compared to Angular JS, Angular has a cleaner structure that allows for more efficient development thanks to features like improved dependency injection.
Add to it the fact that you want to create a website using a standard, accepted format. You can create a dynamic website if you use Angular and Bootstrap.
Bootstrap is an extensive repository of code snippets in CSS, HTML, and JavaScript that can be used repeatedly. Moreover, it is a front-end framework that helps programmers make responsive websites.
Architecture Model
While Angular has a component-based architecture, AngularJS employs the model-view-controller (MVC) pattern. That's right; it has both components and directives, with the former functioning more like a directive than a templated one. For creating a highly adaptable user experience, Angular architecture is the go-to choice due to the independence of its components.
Type of Language
The primary distinction between Angular and AngularJS is TypeScript versus JavaScript. Indeed, TypeScript excels in many respects. It can manage massive projects with ease.
Since a programmer's work is checked for mistakes as they type, productivity decreases, and inefficiency decreases. In conclusion, TypeScript's object-oriented nature makes it easier to produce more reusable code.
Materialistic Design
Google's well-known Material Design Specification was brought to life with AngularJS material, which received support from 2014 to 2017. In 2016, Google released a major update introducing Angular Material, a TypeScript-based material design. In addition to being more adaptable than its predecessor, Angular Material makes responsive design implementation a breeze.
Performance
Even in speed, Angular is vastly improved over its predecessor, AngularJS. Angular is superior to AngularJS because it uses a component-based architecture rather than the more conventional MVC.
Mobile Support
Though it may be used to create dynamic web pages, AngularJS does not yet support mobile browsers, and there are no plans to add this feature to a future version of the framework.
Benefits of Migrating from AngularJS To Angular
The justifications above are primarily technical in nature. Of course, there are practical reasons for doing so as well. Following are some of the benefits of the AngularJS to Angular migration plan.
Support and Updates
That is the single most important benefit of switching to Angular from AngularJS. AngularJS hasn't seen any significant updates in eight years. However, Angular continues to have robust support, and new upgrades are regularly issued.
Optimized Development
Remember that Angular was not created as an improved version of AngularJS. Angular is more advanced than AngularJS in terms of its architecture, structure, and functionalities. Cleaner code, more efficient architecture, and a more fruitful development process are just a few reasons why Angular is the superior framework to AngularJS.
Because of this, as well as the fact that TypeScript is used instead of JavaScript, the framework is compatible with a wide range of devices and browsers and employs a sophisticated data binding technique. It is far more effective than AngularJS.
Mobile Directed App development
According to Statista, mobile devices accounted for 54.8% of global internet traffic in the first quarter of 2021. Internet use through mobile devices has increased over the years in every region.
The ability to function on mobile devices should be a top focus. A fortunate opportunity exists for AngularJS users to upgrade AngularJS service to Angular and add functionality for mobile devices to their commercial applications.
Cost Optimized
The ultimate goal of migration is to increase development efficiency by enhancing code efficiency.
Consequently, the development life cycle is shortened, allowing you to save money while achieving significantly superior results. Additionally, your team can reduce its reliance on external resources by using the official Command Line Interface that Angular provides.
AngularJS to Angular Migration – The Bullet Point Steps
When your business or service delivery model depends on a certain piece of software, this problem can have serious repercussions. This is why a strong AngularJS to Angular migration strategy is essential. Even though it is not comprehensive, this brief guide should give you a sense of the project's scope.
- Get ready by installing the @types/Angular package for TypeScript. Next, with the help of the TypeScript Compiler and integration of TypeScript modules, make TypeScript compatible with the legacy JavaScript code.
- Build a new version of the app using the Angular CLI framework. Some developers bypass Angular CLI's built-in support for Webpack and use Webpack directly instead. The AngularJS files should be copied to a new folder. In this way, the Angular app's functionalities would be linked to one another without any manual work on your part.
- Take advantage of the ngUpgrade's handy toolbox to run two versions of your app's framework in parallel after implementing a hybrid update. Because of this, moving is less of a hassle.
- Send across specific components and services. Suppose you want to use an Angular component in an AngularJS part of your project. In that case, you can use the degraded components to accomplish so. Transferring the AngularJS part of the app to the new Angular version could necessitate rewriting parts of the code.
- Last but not least is routing, which is typically accomplished with UI-Router. Both ngUpgrade and UI-Router have built-in support for hybrid migration, and ngUpgrade does so automatically.
Wrapping Up
The fact that AngularJS is about to reach the end of its support lifespan should be strong enough to switch to the more modern and updated Angular framework. We also recommend moving from AngularJS to Angular due to the fact that Angular is more robust and efficient than its predecessor.
