AngularJS to Angular Migration: Do’s and Don’ts, Pros and Cons

In 2021 AngularJS to Angular became an important issue as the support of AngularJS came to an end. Even so, there are a few companies that haven’t yet completed their AngularJS to Angular migration. If you are one of them, don’t worry, we can guide you through the process.

Why migrate AngularJS to Angular?

First things first. Why migrate from AngularJS to Angular? The reasons for moving from AngularJS to Angular can be varied. Google’s decision to discontinue support is just one of the reasons, but it’s not the only one. 

Let’s start by looking at what Angular and AngularJS are. AngularJS is a JavaScript framework launched by Google in 2012. It was developed to shorten the process of development while making it easier to test. An extended complex code of 17,000 was rewritten to just 1500 in three weeks, which impressed Google executives enough to launch. As demand for AngularJS grew, core developers improved everything they could before hitting the wall. It became clear that a new framework had to be created to meet the new demand and new requirements for app development, which created the need for companies to upgrade AngularJS service to Angular.

AngularJS to Angular Migration Benefits

So, why migrate now? Here are just a few of the benefits of migrating: 

  • Ease of Use: AngularJS is less reusable than the new version. Angular has a component-based architecture, high testability, and easy maintenance. While AngularJS is flexible, Angular is better structured and more manageable if you want to create large-scale applications. 
  • Update: Google has stopped technical support and upgrades for AngularJS, which should be of considerable concern. You need updates to keep your project stable. Angular will launch upgrades every six months. The sooner you shift, the easier and cheaper it will be. 
  • Speed: Angular makes it easier to develop larger apps. There’s a faster compilation, improved debugging, and greater flexibility. Angular uses TypeScript to reduce runtime errors and optimize the code. While AngularJS relies on third-party tools, Angular uses CLI (Command Line Interface), which decreases app development duration. 
  • Mobile-orientated: AngularJS does not support mobile devices, but Angular lets you create lightweight apps for mobile devices.

Do’s and Don’ts: Creating an AngularJS to Angular migration plan

Every business that wants to migrate must have a migration plan in place. Here are just a few of the essentials: 

  • Don’t fail to prepare. The better you prepare, the easier it will be to migrate.
  • Do choose the tools you’ll use. Pick toolkits that the crew knows and will use in your projects, so you don’t need to scramble for a replacement. 
  • Do assign roles within your team. Appoint people responsible for every stage of the work. Work with your CTO to assign team members to implement new features and migrate the old web app functionality. 
  • Do choose steps to migrate from legacy to updated technology. Make sure you make your plan and write down sub-steps for the moves. Some jobs may have additional complexities, require recommendations, or may not be suitable for off-the-shelf solutions. 
  • Do consider additional actions. Teams must plan for extra features that need to be added in the future. You can’t implement everything at once. Consider your Angular-based product as an MVP. Discuss it with your team and decide which functions to implement and which ones to hold back on until a later stage. 

Your goal during the migration should be to minimize the development time of hybrid web applications. The longer a project is in a hybrid mode, the more difficult it becomes to maintain. Two code bases will result in users getting extra megabytes of JS-based code, which can impact the load speed. It can also be hard for your coders to deal with two frameworks while releasing updates and maintaining the web service. 

Google’s announcement to stop updating AngularJS was one that caused ripples of panic in the development community. However, many companies have since migrated successfully and realized the benefits of using Angular. Know that AngularJS to Angular migration is inevitable. Don’t delay. Find a team to help you manage the migration if you need to. The benefits will far outweigh the disadvantages.
