Understanding the Architecture Overview & Concepts of Angular
Understanding Angular Architecture Overview
Angular’s architecture is based on modular and component-based design principles that make it scalable and flexible. Its architecture is divided into three main parts:
A component is a reusable Angular code block that represents a specific part of the user interface. It can be seen as a combination of HTML, CSS, and TypeScript files that work together to form a single user interface. Each component in Angular has its unique properties and methods and can be used to build complex user interfaces. Components also allow you to separate the business logic and display the content of your application into easily digestible pieces.
A module is a container for a particular collection of related components and services. It serves as a logical boundary in your application. Modules allow you to organize your application into related collections of code blocks, making it easier to manage. A module can be seen as a unit of functionality that can be loaded lazily or eagerly depending on your application’s needs.
A service in Angular is a singleton object shared amongst components that handle the business logic of an application. Services are responsible for providing application logic that is not component-specific, such as data storage, API calls, and other business logic operations.
Understanding Angular Concepts
Data binding is the process of connecting the application’s data model with its user interface. Angular provides a robust data binding mechanism that enables developers to reduce boilerplate code and increase efficiency. There are four types of data bindings in Angular:
– Interpolation: For displaying the values of variables
– Property binding: For passing values to elements’ properties
– Event binding: To handle events such as click, keypress, mouseover, etc.
– Two-way binding: To bind both input and output variables at the same time.
Dependency injection is a design pattern that enhances the flexibility, scalability, and testability of Angular applications. Angular application components rely on various services and objects to function correctly. Dependency injection enables these components to access these services and objects effortlessly. It helps eliminate tight coupling and enables developers to build applications that can easily be tested and modified.
Routing enables developers to navigate between pages and components in an Angular application. It involves mapping URLs to specific components. Angular provides a powerful and flexible routing system that enables developers to create complex routes quickly.
