Angular is a favorite of both front-end and rear-end developers. It’s unsurprising that Angular has become a favorite among front-end and back-end developers. Businesses should start planning the migration from AngularJS into Angular. The migration is now a crucial issue for developers and companies, as AngularJS’s support will end on December 31, 2021.
AngularJS projects are also susceptible to security vulnerabilities and threats. Before migrating a project, it is crucial to understand the business case and consider its benefits. Let’s start with the “Why ‘…” section.
Why migrate from AngularJS
Consider these important reasons to migrate:
Architecture
AngularJS uses the MVC architecture, whereas Angular is a component-based architecture. The Angular architecture, which is based on components that are independent of each other, is preferred for creating the user interface.
Language
The main difference between AngularJS and TypeScript is that TypeScript is used in the former, while JavaScript is used in the latter.
TypeScript is based on Javascript but has more features. TypeScript, and by extension, Angular, is a powerful tool for front-end web development. This also increases efficiency as the programmer can detect errors while coding automatically. TypeScript is an object-oriented programming language that helps programmers write code that can be reused easily.
Mobile support
AngularJS is a mobile-friendly framework that can create native mobile apps.
Performance
AngularJS is faster than Angular in many aspects, including performance. AngularJS is much slower than AngularJS because of its component-based architecture.
AngularJS’s TypeScript language is static-typed, eliminating various runtime errors.
Let’s now look at the benefits of migration for businesses.
The Business Benefits of Migrating from AngularJS To Angular
This article will explain how this migration is beneficial for your business.
Sustainable and safe
Angular has architecture-supported components or services, in other words — modules. Modules enable the organization of functionalities in an application by breaking them down into reusable bits of knowledge. Each bit is responsible only for a single feature, independent of the system and its APIs. This ensures that maintenance is easier when the development team can swap out one component for another without having to rewrite the entire code.
Code Optimization
Every little cost saved adds up. Cost optimization isn’t only about reducing costs. It’s about getting enough value for your money.
AngularJS has a command-line interface allowing your developers to work without many third-party tools.
You should not hesitate to migrate if you can save money by switching from AngularJS and achieving better results with Angular.
Mobile-driven approach
Angular allows lightweight applications to be created, offering faster downloads. This is just one of many reasons Angular uses “lazy scripting.” It would then only load modules when they are needed. Certain packages (such as animations) have also been removed from the Angular core. This allows for lighter and faster performance.
After you’ve learned about the benefits of this migration, let’s look at the two approaches.
AngularJS Migration: AngularJS Migration Approaches
Rewrite
Many legacy applications need rewriting as they are often out of touch with current principles. Migration can be difficult if a new code is not developed.
Even more modern applications may need to be rewritten for various reasons. Rewriting, for example, allows you to add new features or make improvements that would not be possible with an update.
Challenge:
It takes more time to do the same work.
Update
Updates are not as flexible regarding options for the new application as rewriting when migrating AngularJS from AngularJS or any other platform. An update is a great option if you already have the most recent version of Angular. AngularJS can be updated using Upgrade – a library provided by Angular that allows you to run both frameworks simultaneously.
Update:
Audit and evaluation of software
Check the stack of tools and libraries that are used to build the project
Define the software modules
Prepare code structure
Upgrade to a newer version
Create the target project using AngularJS with legacy AngularJS Project Parallel
Select the appropriate libraries according to your requirements
Add new features and create modules according to the priority of your Angular project.
Tests
Introduce manual or automated testing
Install CI/CD pipeline
Challenge:
It is more difficult to maintain
AngularJS is a powerful tool for building web applications.
Futuristic, smart thinking will include upgrading the AngularJS framework to Angular. This is a newer, more updated version. Make a plan to upgrade from AngularJS.
