The IT industry is growing by leaps and bounds. Not just businesses but even people are striving hard to become a crucial part of such a profit-spinning realm. And since you are reading the following post, I assume that you are also willing to jump into the development bandwagon and make an insane amount of money out of this lucrative field. Not to mention the tech industry seems to be crying out pretty loud for talent and an insane amount of hard work. The following post basically focuses on what are certain aspects that have to be taken into consideration for becoming a skilled Angular developer.
Now before you begin there are certain basic aspects that must be taken into account. For example, Angular is one of the leading and biggest frameworks available with a wide range of features and functionalities. You see it is strangely believed that in the technological realm, things keep on changing on a regular basis but that’s not always the case. There are certain concepts that have been in vogue for years and still somehow manage to maintain their top spots. Mastering these concepts is extremely important for an Angular developer to succeed.
First and foremost, you need to understand what Angular architecture is truly made of. Well, it comprises Ngmodules where the framework’s building elements are present. Now each one of these is meant for a specific purpose. So if you think an app simply comprises a root module then you are totally mistaken.
Components are one of the basic foundations of any angular architecture. The root component is mainly used to create a tree of loosely linked different components. The child components are added later on. There are basically three main components – one is the root component, TaskAddComponent and TaskComponent. You see this component-based architecture is one of the core features of the Angular framework as due to this it becomes pretty easy for Angular developers to break down large applications into smaller ones.
Now without any further delay let us explore certain aspects and factors to take into account for any and every Angular developer or aspiring programmer across the globe.
Concepts to Master
#1 Modules and Libraries
One of the basic yet most important concepts to take into consideration is modules and libraries here. Unlike other popular frameworks, Angular’s module architecture is a bit different. Still, it turns out to be one of the most challenging aspects to grasp especially for those who have just entered the realm. And you know what’s the trickiest part? Here module architecture is highly preferred, the ES imports.
As a skilled Angular developer, it is extremely important to know whether you can separate and split the app’s functionality precisely in well-defined modules or not. For that, you need to get well-acquainted with the different kinds of modules available.
- Declarations/widget module
- Service module
- Routing module
- Domain/feature module
- Core/Shared module
Also before writing a module, you must know what kind of module you will be writing in prior. In case, you don’t know the answer, it is advisable to learn about all the aforementioned modules, especially routing and service. In addition, you must know when you should use a library and when to use a module. For example, if you are using a monorepo, then the library can work more wonders than a module.
#2 Forms and Validation
Today all sorts of app development is done in terms of CRUD applications. To gain a competitive edge, developers are asked to spend more and more time writing forms and thus, it becomes extremely important to learn and get acquainted with all these Angular forms. Now usually, forms consider ReactiveFormsModule where the concept of two-way data binding and ngModel is completely ditched. Angular forms API are extremely easy to understand and of course, this also includes the right adaption or else, things won’t work out as expected. Now here when you are dealing with forms you must be sure that they are well or should I say very much in sync with the data structure’s types.
Another crucial aspect to take into consideration is learning how validators work in conjunction with CSS. Also, CSS can assist you well in speeding up workflow and turning your app into a seamless error-handling-ready space.
#3 Separating concerns between components, services and directives
Separating concerns is another interesting concept that must be taken into account whether you are just a newbie or a well-experienced Angular developer. Of course, earlier you must have been taught how to keep your components lean and services fat but to be precise there aren’t many substantial differences available in the newest versions.
State – One of the major aspects here to take into account is the state. You need to understand the state, where and how the data can be accessed and shared outside of a component. And it seriously doesn’t matter whether the component turns out to be local and encapsulated. Now further below I would like to mention certain situations that must be taken into account.
- In case, if the state is shared between the components. If not, can it be well accessed from different services? If so, then you need to place the state in a service. Here it doesn’t matter what state management tool is used, all that matters is that it has to be a service.
- Now in case, if the state is local and only used within a component, then developers require to store it in a component.
DOM Manipulation – Another interesting concept that makes the Angular framework a cut above is DOM manipulation. Now, most of the time DOM manipulations happen within Directives. Now here’s an example for you. Let’s say: You are adding a drag-and-drop functionality, so what you can do is create a component and bind events from there but have you well-defined how the components look and how certain components’ features and functionality behave?
Directives are reusable, especially in the Angular framework, so there is no point in keeping them unused. In fact, these can take off lots of responsibility from different components.
Of course, this is not it! There are several other concepts and aspects that can assist you in acing your Angular development game. I hope you did find the following post insightful. Keep watching the space to know more.
