Migration from AngularJS To Angular: Why And How You Do It

Hello developers’ community! Recently, in the world of web development, many IT professionals have begun to switch from one framework to another, such as from AngularJS to standard Angular. And it’s not just for fun, it’s for a number of reasons to improve the overall development process. If you have long been interested in the question if this approach is receptive to the development of large projects, whether all the progress of work is lost in the process and how to do it, then this article, which is called ‘Migration From AngularJS To Angular: Why And How You Do It’ definitely needs your attention. Read more and discover!

To begin with, it is necessary to understand the main reason for migrating to Angular. First of all, any web project that is developed must be highly functional and user-friendly, so the developer tries to make the most convenient interface, quick response and full functionality. Since the technical part of the whole development process is the most important, the Angular specialist pays attention to things that slow down the entire speed of the development process and, accordingly, further functionality.

In the forums about AngularJS you can read about a number of things that slow down the work of developed applications, such as poor performance and durability. And during the creation process, there may be problems with the behavior of the framework when working with scopes and controllers. As well as the lack of server visualization, which interferes with the work speed of the developer and thus the productivity of his workflow. You may wonder if Angular really solves all these problems? The answer is obviously yes.

When developing with Angular you will get high performance, flexibility, clear behavior, and server visualization. The Angular is simply filled with the perfect feature set for these requirements. Also note that the migration from AngularJS is clear and concise, and further work with TypeScript is a convenient style of work even for beginners in web development. In addition, Angular has features to speed up optimization. It is a large ecosystem that has a core on which a developer can impose everything he needs, i.e. work with forms, backend, and even development for mobile applications. A distinctive feature is the ability to control the framework, which means you can call or stop a certain process during development if you need it.

Now that you know the main reasons for migrating from AngularJS to Angular, we can move on to how to make it a reality. In general, there are several methods of this transition, some of which are more manual, while others are automated and facilitate this process. If you have enough time and patience, you can rewrite your codebase on Angular manually. One of the advantages of this method is that in the process of migration everything is clear, you do not have to learn anything new. But the main disadvantage is the delay in development, and therefore the postponement of deadlines and the possibility of not completing the project on time. A more automated method is to use ng-metadata. This is a library, a set of decorators that allow you to write code in AngularJS as if you were doing it in Angular. As a result, you get code almost identical to Angular, although it was originally written on AngularJS. As for the advantages of this method, there is a simple integration that is almost completely automated, but at the same time you will not get high code performance. And you probably read about the third way of the migration from AngularJS on the forums – a hybrid transition. With this option, part of the program works in the context of Angular, and you get almost all the benefits of the framework. But here you need to pay attention to the fact that as a result your application will be seamlessly integrated for Angular, so you need to be careful in the process. Absolutely all migration methods require a stage of preparation for this process in order to obtain a high-quality transition of big data of your project without any losses.

I would also like to draw your attention to the fact that the Angular team of creators has developed two tools that greatly facilitate the migration process. Their big advantage is the ability to find out if the transition is correct and how to avoid any errors that may affect the functionality in the future. The first ngMigration Assistant tool runs on the command line and analyzes any size of the code base while recommending the optimal migration way. The developer can even see special statistics that are created for his project and show how difficult the transition, size, content and architecture of the project is. According to these characteristics, the ngMigration Assistant offers some recommendations for migration and takes into account all the features of your project. It will be important for the developer to be able to see the stages required for migration. The second tool, which is still similar to the developer community, is called ngMigration Forum. It contains all the relevant information on migration methods, and you can find solutions to all questions and problems that can arise during the transition. You can completely rely on the information of the ngMigration Forum because there are experienced IT experts.


In the article ‘Migration From AngularJS To Angular: Why And How You Do It’ you read about the main reasons for switching to Angular, which is primarily related to the functionality of the developed web applications and the speed of the work process of frontend specialist. There were also migration methods, as well as more manual and even automated. Hope this information was useful and interesting for you. I wish you an easy and stress-free migration process to Angular!
