Migrate from AngularJS to a Newer Technology
AngularJS is needed to be migrated when keeping the dependencies up to date and some security Upgradation. It increases the code maintainability, performance, tools, language, and better architecture which are measured as flaws in the previous version. Migration considers some major points such as codebase size and skillsets.
Code Maintainability: Once the application code gets longer, there will be some complexities like tight coupling, longer methods, large classes, duplicate codes, and bugs filled will be there in the code. If we do change in the same version, we need to rewrite the code. But migrating makes the way easier by re-factoring facilities.
Performance: If an application code has a large code, the performance will be degraded with the data count. But the higher version reduced the file size by 60% compared to the previous. It leads to accelerate the application performance by Code Generation facilities.
Tools: Many external tools will be used for testing the application developed in AngularJS which can be reduced in the migrated versions by its inbuilt command line, testing, and debugging tools that have unique installation procedures, syntax, and configuration.
Language: Angular uses TypeScript for type safety while javascript does not offer to store any value for typescript. TypeScript supports TLS for type inference (TypeScript Language Service).
BetterArchitecture:
AngularJSTwoway binding sometimes results in delays. When migrating to the higher version it will be resolved with the hierarchy of components and services to reuse the elements.
Size of CodeBase: Code size will be reduced in a higher version when migrating that helps a more robust and structured code.
Skillsets: Migration of AngularJS to the higher version will also give the benefits such as Type Inference, Optional static typing, Access to ES6 and ES7 features which attract more people to the project.
Must-know facts for migrating from AngularJS to Angular
AngularJS will be stopped its support officially on 1st July 2021. But updated Plugin supports Angular
The application developed for the longer purpose should be migrated to the higher version which should be adequate to the existing base code support.
Migration required to decrease the risks of delayed launches which is done with the lower version which has inconsistent codes.
Best Migration Processes
The migration of the older versions to the new one can be done in two approaches effectively.
Incremental (Modular Approach): the First approach is to migrate the application module by module. It would be better for large and complex applications. Successful upgrade lies in migrating the application incrementally by running two frameworks of the same application in a parallel manner.
Big Bang: This is another approach which can be done for small and medium size of applications. Big Bang approach fastens the implementation process of migration by lesser efforts. However, it is a bit complicated to the users by learning a new system and it involves a lot of risks that can not be predicted easily.
Benefits of Migrating from AngularJS to Angular
Our application will be easily understandable and migrated when the logic has AngularJS code which is UI (User Interface) ready.
l The migration does not require to update new plugins when AngularJS and Angular support mere plugins.
l TypeScript is the main advantage of Angular which consists of type-checking feature and reduced runtime errors that helps the developers to identify the bugs and errors even the beginning of writing the code. TypeScript of Angular splits the compilation error which is done as interpretation in JavaScript.
l Migration to Angular reduces the time taken for configuring separate tools used for the unit testing process.
l Anyhow, the support of AngularJS will be stopped and it is better to migrate to the higher version within July 2021.
l Comparing to AngularJS, Angular has delivered a high performance with less data size.
l Angular has effective page data which is far better than of AngularJS which forces to the migration process without delay.
l Ionic frameworks supported by Angular that leads easy developing of Mobile Apps, Web Apps with all the special features required for basic applications like Cameras, Notifications, etc.
l Angular simplifies the process of migration which improves the performance for our applications regardless of large, small, medium sizes.
Conclusion
Migration process is required for the applications developed in AngularJS as it has the complications as said above. Learn more about the migration in our AngularJS Training in Chennai at SLA Jobs.
