When designing a web application with AngularJS, here are some key considerations:
MVC Architecture: AngularJS follows the Model-View-Controller (MVC) architectural pattern. This separation of concerns helps in organizing the codebase and improves maintainability. The model represents the data, the view handles the user interface, and the controller manages the interaction between the model and the view.
Directives: AngularJS uses directives to extend HTML with additional functionality. Directives allow you to create reusable components, define custom behavior, and manipulate the DOM. They are marked by attributes or elements in HTML and are a powerful tool for building dynamic and interactive interfaces.
Data Binding: One of the key features of AngularJS is two-way data binding. It automatically synchronizes data between the model and the view, eliminating the need for manual DOM manipulation. Changes in the model are reflected in the view, and user interactions in the view can update the model.
Templating: AngularJS provides a powerful templating system that allows you to define dynamic views using HTML templates. You can incorporate expressions, filters, and directives within the templates to manipulate and display data. Templating makes it easier to create reusable and maintainable UI components.
Services and Dependency Injection: AngularJS utilizes services to share code and data across different components of an application. Services are singleton objects that can be injected into controllers, directives, and other services. The dependency injection system handles the wiring and instantiation of these services, promoting modularity and testability.
Routing: AngularJS includes a built-in routing mechanism that enables the creation of single-page applications (SPAs). You can define routes for different URLs and associate them with templates and controllers. This allows for the loading of different views and updating the URL without reloading the entire page.
Integration with RESTful APIs: AngularJS can seamlessly integrate with RESTful APIs to fetch and manipulate data from the server. You can use AngularJS's $http service or third-party libraries like ngResourceM or axios to make HTTP requests and handle responses.
AngularJS Modules: Modules in AngularJS help in organizing and structuring your application. They allow you to encapsulate related components, services, and directives. AngularJS modules provide a way to manage dependencies and enable code modularity.
