Need Help With Your SEO?

Are you ready to know what I’m gonna tell you about not serious but a really important and valuable topic at the same time – “Converting an AngularJS app to Angular – know the tools.”  I’ve been thinking about what article to choose for drawing your attention.  In my opinion, you will like this topic because AngularJS to Angular is one of the important technologies. Therefore, many people want to start learning this material. This is not particularly new and has been used for many years. If you are a newcomer to this, I highly recommend you to read this topic. For very active beginners it will be very useful. As you understood today I will help you convert an AngularJS to Angular.

Now, let’s examine this in a little more detail.

Tools to help with AngularJS to Angular Migrations

Many developers are starting on the migration journey of making AngularJS applications up to modern-day web development models with Angular, and there are a lot of ways. It can be exciting to know which upgrading path is right and where to find direction on how to migrate, but it doesn’t have to be. Have you ever heard of tools? If , no. It is time to discuss them. I want to introduce to you two new tools that will help you. These tools are very popular and used very often.

ngMigration Assistant

ngMigration Assistant is a command-line tool that explains an AngularJS application and supports a migration path. It presents statistics on the complexity, size, and models of an app. It describes the important development work for migrating to Angular. ngMigration Assistant is intended to provide easy, clear, and helpful directions for how to migrate your application. It explains any AngularJS app — large or small — and offers suggestions about potential strategies that may suit your application. It doesn’t take into account every possibility but holds some of the most important parts to consider, such as code area and complexity. The ngMigration Assistant tool is an excellent place to start when thinking of migrating an AngularJS project. Be informed that the tool doesn’t include everything and there will be new areas of the application outside libraries and some thought, for example, that will need some reworking during migration. It’s a good first step but not easy to complete.

ngMigration Forum

The new ngMigration Forum is a community hub that gives you the possibility to join an open place where you can find information about migration paths, tools, and to incorporate some of the best information and specialists from the web. ngMigration Forum is provided towards answering your migration questions, knowing helpful tools, and guiding you to a migration solution. To put it simply, it is a community to learn, review, and share information on migrating to Angular. From my point of view, in the Forum, you will find an array of valuable information covering from examples of why upgrading is important and from a professional and business aspect to an overview of the possible migration paths. You must admit that there are many migration paths.

It is usually accepted that ngMigration Forum is the place to produce all our opinions and insights together, to share valuable information and wonderful tools.

I hope all these tools will help you to make the right decision of choosing the correct variant. Please, choose one of these tools for the best results. Some time ago, one American businessman said: “You don’t have to be a genius or a visionary or even a college graduate to be successful. You just need tools and a dream.” It may be an interesting option for all who want to start converting an AngularJS to Angular.

Deciding how to migrate

I want to introduce three main ways of migrating an AngularJS application to Angular. I will clarify the most important approaches.

Complete Rewrite in Angular

I recommend you the first choice to make when thinking about migrating your Angular application. Especially, whether you will do it incrementally or not. If you need to support an actual application or the application is too large to migrate it completely in a reasonable time frame then an incremental upgrade may be the only way open. Well, my personal feeling is, if the application is small enough or if you are ready to stop holding the actual application or allocate enough devices then a complete rewrite is actually the most honest approach. Migrate the whole application without supporting the AngularJS version:

Pros

  1. You don’t have to worry about upgrading or downgrading elements.
  2. No interoperability problems between AngularJS and Angular.
  3. Chance to refactor areas of the code.
  4. Can benefit from Angular pieces quickly.

Cons

  1. The application will be offline while the migration or you will need to copy the codebase to a new container.
  2. You don’t see the profits until the whole application is migrated which could take some time depending on the overall size.
  3. As you will not see the whole application going until the end of the migration you may see results as you build more features.

So, as you can see, this point will help you in deciding how to migrate. Please, follow these points and the work will be performed successfully.

Hybrid applications

ngUpgrade

Another point worth noting is ngUpgrade. IT is an Angular library that enables you to build a hybrid Angular application. The library can bootstrap an AngularJS application to an Angular application enabling you to mix AngularJS and Angular elements inside the same application. It’s important to know that ngUpgrade allows you to upgrade AngularJS directives to run in Angular and downgrade Angular elements to run in AngularJS.

Horizontal Slicing

When migrating is performed with the usage of a Hybrid approach two methods will slowly move your application from AngularJS to Angular. As everything in this life, the horizontal slicing has its advantages and disadvantages which I’ll explain further.

Horizontal Slicing is a term used to explain the method of migrating which uses building block elements first and then all components that use these elements and so on until you have upgraded the whole component tree.

Vertical Slicing

Vertical Slicing illustrates the method of migrating where each program or feature of the application are migrated simultaneously. Unlike horizontal slicing, views won’t mix AngularJS and Angular components, in turn, each view will consist only of components from one framework or the other. According to different thought of experts, if services or elements are shared across the application then they are repeated for each version.

So, in this point you’ve read interesting facts about deciding how to migrate. Please be very attentive and the results will be very good.

Conclusion

So, in conclusion, I hope this article about converting an AngularJS app to Angular gave you some useful information. I also recommend you to take a look at the list of these useful tools. Here is the list of them:

  1. ngMigration Forum

So, I know a famous quote: “You cannot judge a book by its cover.” Please choose one of these tools and try them out in your work.

Also, I recommend you to read useful points about deciding how to migrate. Here are those important points:

  1. Complete Rewrite in Angular
  2. Hybrid Applications
  3. Horizontal Slicing
  4. Vertical Slicing

As you can see, this service is represented by a great variety. Of course, if you ask me what to choose, in my opinion, Angular will be the right variant for you. So, try and begin to use this framework. Thank you for reading! Stay safe and have an amazing day or evening!
