There are a lot of means to facilitate the development of web apps nowadays and some of them are based on Angular templates. Usually, such packages include design patterns and view-layer UI components combined and based with the help of user-experience guidelines. The majority of such projects are open source what makes these Angular-backboned solutions very famous in the development world.
Initially, Angular development has not been planned as a big project. It was a single-man project which later grabbed Google’s attention. Basically, due to Google’s intervention the old framework that was best suitable for small apps became obsolete and the development shifted to huge web apps building. But then, one thing should be mentioned, these changes brought to life that total reconstruction of the Angular templates to meet the demands of the growing industry
From the developer’s point of view the biggest improvement to the AngularJS 1 framework introduced by Google was the application of the component approach. Angular programming basically is not very beginners-friendly because of its directives abundancy in setups and services. Though, to think logically, the ones that are frequently used could be counted with the help of 10 fingers on your 2 hands. This particular situation put many of the developers in the state of frustration and the juniors, in particular, were not happy about the framework at all.
The main idea of this approach is that the components could be developed independently and be compatible afterward. Such attitude is ideal if the development stages of your app are shared between several teams of Angular developers who do not necessarily work together. At the same time, it is very beneficial for the whole architecture of the project because it makes any code change happen fast and easy.
But Angular JS 1 wasn’t designed in this way because of the difficult syntax and various methods of directives coding put obstacles to truly component approach from the side of the framework. With the time, it became truly problematic to meet the deadlines, especially if the projects developed on Angular were big, heavily functional apps. Developers had to dedicate much of their time to understand the logic of the code written earlier by the other team and this led to bugs overloading and slowing the whole process of development down.
Angular JS 2.0 is on rise
AngularJS 2.0 has a better-organized syntax and the framework facilitating the development of apps. The documentation for this version of Angular is transparent and occupies only a couple of pages and to the top of everything it’s self-explanatory. This Angular framework has the ability to use different components and the code tends to be better supported. One of the biggest pluses of the Angular framework is clear architecture, the language, and easy-to-use attitude. These three main factors are the best binding means for big teams that are doing their best and build complicated and large apps. Anyway, the only way to make you comfortable while working with AngularJS 2.0 development is practice as much as possible.
AngularJS vs. ReactJS
The differences between the two frameworks are minimal and if someone decides to recommend one over the other that’s a difficult task to do. The slight difference could be in the fact that AngularJS development is positioning itself as a dictating or prescribing one, so it tries to ‘show’ the developers how the future app should look like. It’s really great from the documentation point of view and very helpful at each development stage of the project. The guidelines originated by the framework itself go through app development stages: accessibility, page-profs, inquiries, etc. Even if you compare the communities behind ReactJA and Angular JS, the latter will be greatly favored by a much bigger community. There are millions of contributors to give professional advice on how to migrate to AngularJS 2.0 though there are still many of those remaining faithful to the old one AngularJS 1.
Migration to AngularJS 2.0
Different kinds of projects could be subjected to migration: small and mid-scaled and even big projects could be moved to the enhanced framework under the condition that it could be an expensive thing to do. The process is eased if your initial project is written in the latest version of AngularJS 1.x, then the transformation to AngularJS 2.0 could be a very seamless one. The most drastic change is made to syntax more than to semantics. In some cases, you have to rewrite the syntax and redo the app. Of course, small apps are easier and less expensive to redo and, eventually, to migrate.
Anyway, before you even consider migrating, please, pay attention to the following issues and the way you would answer these questions:
- The time period of the project development.
- Any anticipated changes to the project during its development.
- What is the stage of complexity for the support of the future project?
- What are the changes in the development teams (location, skills, number, etc.)?
The reality of the development world is that there are still many teams who keep building up apps using AngularJS 1.x but this could change in the coming future as the old technology could be more expensive than the new one. It’s a proved fact that to enter into the development using AngularJS 2.0 is already more cost-effective than its forerunner.
If the development team could provide a module upgrade and the documentation side is relevant and neat the migration process is facilitated as well. On the every stage of migration, please, do check with Angular Style Guide. It’s even better to do so before the upgrade process. So, you’ll have a clear picture on the level of the components coupling inside the project and shed some light on the directives and methods used. Your final decision should be based on the capabilities of your development team and the basic features of the apps you would like to build.
