Study Notes
Other JavaScript MV* Frameworks
- BackboneJS and EmberJS are notable alternatives to AngularJS.
Conceptual Overview of AngularJS
- Utilizes two-way data binding, treating the model as a single source of truth.
- Directives allow HTML to be extended for richer functionality.
- Follows the MVC (Model-View-Controller) architecture.
- Employs dependency injection to manage services and components effectively.
- Facilitates testing, ensuring code reliability and robustness.
- Supports deep linking, allowing URLs to map directly to application routes.
- Enhances server-side communication, making data retrieval seamless.
MVC Architecture
- MVC is a software design pattern for web application development consisting of three components:
- Model: Maintains and manages application data.
- View: Displays data to the user and presents it using UI templates.
- Controller: Interacts with the model and view, managing application logic.
Key Concepts in AngularJS
- AngularJS is based on the MVC framework, isolating application logic from UI for better maintenance.
- Controllers handle requests, prepare data from models, and facilitate communication between the view and model.
MVC Explanation
- Model: Manages data, processes updates, and responds to the view's requests.
- View: Presents data in a specific format, often using template systems like JSP and integrates with AJAX.
- Controller: Responds to user interactions, manipulating the model's data according to user input.
Benefits of AngularJS
- Well-established framework with a robust community and extensive learning resources.
- Particularly effective for Single Page Applications (SPAs), allowing dynamic updates without full page reloads.
- Promotes structure and maintainability through MVC, making it suitable for complex applications.
- Large development community provides ample resources for troubleshooting and understanding.
Features of AngularJS
- Open-source and free framework under Apache License version 2.0.
- Employs the MVC approach for clear client-side application development using JavaScript.
- Supports development of Rich Internet Applications (RIA) with cross-browser compliance.
- Automatically manages JavaScript code, optimizing for different browsers.
Document Object Model (DOM)
- DOM represents structured HTML and XML documents as a tree of objects.
- Defines methods for accessing, manipulating, and modifying document elements via JavaScript.
Directives in AngularJS
- Directives are markers on DOM elements that enhance functionality or behavior.
- Extend HTML with new attributes, enhancing interactivity and capabilities.
- AngularJS includes a set of built-in directives while allowing custom directive creation.
Important AngularJS Directives
- ng-app: Initializes the AngularJS application and defines its scope.
- ng-controller: Assigns a controller to the view, enabling methods and variables for interaction.
- ng-bind: Binds the text content of elements to expressions, updating content automatically.
Purpose of Directives
- Directives enable the creation of custom behaviors for various elements, enhancing reusability and modularity in applications.
