Greetings to you, my friends and colleagues. Do you have a few minutes? I have prepared for you a new topic about “Pros and cons of Angular migration.” App’s popularity has definitely grown in the digital age, and a large number of apps have hit different heights in the business. In this article, I would like to provide you with the information about Angular. To be specific, I will tell you about pros and cons of Angular migration.
Let’s take a closer look below:
What’s Angular?
First of all, it is worth remembering what Angular is. Angular is a framework that makes it easy to develop web applications. According to modern research, Angular is supposed to be the most commonly used technology. Of course, I want to present you a list of some most important Angular concepts:
Modules
It is used to speed up complicated app development. To provide help for the development of complicated applications, the code can be organized into different useful modules. Containers produce a sense of how the application components fit together. Their main aim is to organize and combine the functional pieces such as elements, directives, services.
Components
It goes without saying that they are supposed to be the building blocks of Angular apps. Any app should have at least one element, associated as a root component that includes all different components. I strongly believe in the fact that they represent the views that Angular can choose among components and change them according to the program’s thought and data.
Directives
Needless to say that the custom attributes turn to the HTML-based syntax. As a rule, they connect ways to the special page details. The research has established the fact that there are three types of directives. As a result, attribute directives that modify the behavior or appearance of an element, component, or another directive; components – directives with a template; and basic directives that are able to add or remove DOM elements.
Data binding
Clearly that data binding is the process that combines a component with its template and allows data and events to flow between them. On the other hand, there are two types of data binding – event binding that provides an app the possibility to reply to the user’s input in the target environment, and kind binding that supports the addition of values that were calculated from application data into the HTML.
Metadata
It instructs Angular about how to prepare or finish a class so that it can configure the normal behavior of the class. The metadata for a service class gives the information that is needed to be given to the elements through dependency injection (DI).
Services
As usual, services are reusable functionalities that are independent from the views and can be called from one central source, and then can repeat the same role in various areas.
So, as you can see, there is a list of some most important Angular concepts. And now let’s move to the next point and gain the knowledge about pros and cons of Angular migration.
The pros and cons of choosing Angular
Like everything in this life, Angular migration has its own advantages and disadvantages. I hope this information will be very useful to you. Let’s observe all of the positive and negative aspects:
The pros of Angular
Below you can read about the most important advantages of Angular:
1. MVC structure implementation
As for Model-View-Controller or MVC structure, I may say that it connects its value to the framework while it creates a client-side app. In addition to this, it sets the foundation for the other important points, like data binding and fields. It connects all the app details automatically without adding a new code. Another factor that must be considered about MVC architecture, is a desire to separate the app logic from the user interface layer and to provide a division of concerns. When we talk about this aspect, the controller takes all requests for the application and then works with the model in order to make any data that is needed by the view. When it comes to the view, then you can use the data that is provided by the controller in order to present a final satisfying answer.
2. Modules
According to the experts’ opinion, the module is identified as a tool that is used to form organizations, which are compared to each other’s directives, elements, pipes, and services so that they can be connected with other modules to create an app. In this regard, Angular-based apps can be held as a puzzle where each module is required to be able to show the whole picture. It is clear from the facts that there is a large number of methods that can be used to add various elements to a module.
3. Services and Dependency Injection
You must admit that a service or element may require other conditional help in order to create a task. A dependency needle design original is used to satisfy these dependencies. You must remember its advantage – dividing the task among several services. It is generally accepted that the customer service will not create the dependent object itself, it will rather be created and injected by an Angular injector. As for the responsibility of Angular injector, I may say that performing service instances includes them into groups like parts and assistants.
4. Testing option
As everyone knows, testing is usually supposed to be an important part of the improvement and creation processes. What I am trying to say is that this framework has been created with the comments that support testing. Furthermore, one should not forget that with the help of DI features, testers can simply include the test data in the controller to check its production and performance.
The cons of Angular
Here you can read about some disadvantages of Angular. It is still considered to be an important tool for the web app community.
1. Learning curve
One of the most striking features of this is that it’s simple to learn Angular during the elementary stages. Needless to say, some individual features of Angular are very difficult, so developers find it hard working with states, DI works at the very beginning.
2. Documentation
It is often said that it’s constantly important to have good documentation to control it when you are planning an app. While the documentation for the framework has been renewed, it still requires some improvement. It should be noted that it would be enough to add more valuable information to some rules and features, identification and changes. It is important to add well-written documentation with step-by-step instructions in order to save time and to explain the method of development.
3. Debugging
I am convinced that debugging is an important step when you create an app. It is easy to use the fields, but trying to debug them might be difficult. Unfortunately, developers were frustrated because there is no idea what scope is being used and what value is being debugged in the app.
4. Search engine indexing
On the whole, I think that search engines still need to see the content and elements of the page in the reference code to prove that it will be recorded perfectly. Don’t forget that there are some difficulties that might occur when you promote up pages.
On the final note, I want to say that Angular is supposed to be a full-featured and effective framework. Adaptability, usability, and maintainability make it individual and give significant possibilities to create attractive and strong web-based applications.
Conclusion
