AngularJS Architecture
Table of Content:
AngularJS is built on the Model-View-Controller (MVC) architectural pattern. This pattern is used to separate the concerns of an application into three distinct parts: the Model, the View, and the Controller.
The Model represents the data and business logic of the application. It is responsible for managing the data and providing methods for accessing and manipulating it. In AngularJS, the Model is typically implemented using JavaScript objects and can be defined using the $scope object.
The View is the presentation layer of the application and is responsible for displaying the data to the user. In AngularJS, the View is implemented using HTML templates and directives. Directives are special AngularJS attributes that can be added to HTML elements to extend their functionality.
The Controller is the intermediary between the Model and the View. It is responsible for handling user interactions, updating the Model and updating the View accordingly. In AngularJS, the Controller is implemented using JavaScript functions that are attached to the $scope object.
The MVC architecture allows for a separation of concerns and makes it easy to build and maintain large-scale applications. AngularJS provides powerful features such as two-way data binding, dependency injection and directives that make it easy to implement the MVC pattern and build complex applications.
In summary, AngularJS is a powerful JavaScript framework that is built on the MVC architectural pattern. It provides a powerful set of features that make it easy to build and maintain large-scale applications and its MVC architecture makes it easy to separate concerns for better maintainability.
What is module in AngularJS Architecture?
In AngularJS, a module is a container for various parts of an application, such as controllers, services, filters, and directives. It serves as a way to organize and group related functionality together. Each module has a unique name and can be defined using the angular.module() function. Once a module is created, it can be added as a dependency to other modules, allowing the different parts of an application to communicate and share functionality. This modular structure helps to make code more manageable and easier to understand, and allows developers to create reusable and maintainable code.
What is Directives and Factory in AngularJS Architecture?
In AngularJS architecture, Directives are used to extend the functionality of HTML by providing new syntax and elements. They allow developers to create custom elements and attributes that can be used in the HTML template. Directives can be used to create reusable components, add dynamic behavior to elements, and manipulate the DOM.
Factory is a design pattern in AngularJS that is used to create reusable objects. A factory is a function that returns an object and can be injected into controllers, services, and other components. The factory pattern allows developers to create objects that can be reused across the application, making it easier to maintain and test the code. Factories can be used to create services, which can be used to share data and logic across the application.
