Popular social media sites like Facebook, Instagram, Twitter and even e-commerce sites like Amazon, Myntra, Flipkart etc. are all equipped with dynamic features to provide a user friendly experience. The banking and healthcare industry uses the internet and mobile apps to provide services to their customers. Have you ever wondered how to develop these applications? How do developers create such dynamic user interfaces? If so, then the answer is Angular.
A brief introduction to Angular
Angular is an open source framework that software developers and engineers use to create single-page dynamic web applications. This is the most popular framework used by many organizations around the world to provide a web-friendly experience to their customers. Angular was developed in 2009 by Google and was originally known as Angular 1. Eventually, its name was changed to AngularJS or Angular JavaScript because Angular uses TypeScript language which is a type of JavaScript.
The Angular framework provides developers with a consistent structure to work with. By using this framework, developers do not have to rebuild codes from scratch. Thus, it saves extra time and effort. Also, JavaScript which is the most common scripting language has failed to create single page applications or SPAs that require better fluidity and modularity. AngularJS was able to provide just that, and frontline web development has become much easier with this framework.
Angular has a number of features such as modules, components, templates, services and dependency injection. In this article we will discuss Angular services and their importance.
What are Angular Services?
Angular services Are used to complete a specific task in a web application. They are reusable codes with a targeted purpose. They provide services to the various components of Angular. Angular Services performs all the operational tasks of the Angular components. When there is data or business logic that needs to be shared across the angular components, a service department is created. A service class is a TypeScript class with a defined function. You can write it once and then inject all the components that require this service. They are implemented through dependency injection.
Angular services carry a single piece of code that symbolizes business logic. This code can then be shared across a number of angular components that use this service. It can be anything, for example a variable, function or feature that the web application needs. Components interact with the user, while services help get back-up support.
Why should we use Angular services?
As discussed above, services in Angular perform the essential function of receiving data from the backend server. Writing a data access code in any component of angular is very inefficient. Thus, a service department is created to perform the specific task.
Here are some of the key uses of Angular services:
- For sharing business logic or data across multiple components
- For features like registration services that are not component dependent
- To contain external interactions such as data access
If the business logic is written in the components, then it will become very difficult to maintain and cannot be reused anywhere. However, creating a service class will keep the components clean and can be reused wherever it is necessary to apply business logic.
Angular services can also be used to create communication between two separate components. Logically this service can be infused into both components to share data back and forth. Because Angular services are individual by default, communication between the two components is possible.
Summary
Easier to check and debug Angular services. They can be used over and over again to provide business logic wherever it is needed. Thus, they play an important role in the Angular framework. Developers use Angular to create visually appealing and functionally efficient user interfaces. And services in Angular help these developers achieve this. Angular developers help their organizations meet their customer requirements and achieve business goals successfully.
