Angular – Features of Angular framework
The Angular framework is packed with robust features that make it a popular choice for building modern web applications. Here are the key features of Angular:
1. Component-Based Architecture
- Applications are developed as a collection of reusable components, making it easier to organize and maintain the codebase.
- Each component encapsulates its logic, template, and styles.
2. Two-Way Data Binding
- Synchronizes data between the model (TypeScript class) and the view (HTML template) in real time.
- Ensures that UI changes automatically reflect in the underlying data model and vice versa.
3. Dependency Injection
- A built-in mechanism for creating and managing dependencies in an application.
- Promotes code reusability and easier testing by injecting services into components.
4. Directives
- Structural Directives: Used to change the structure of the DOM (e.g., *ngIf, *ngFor).
- Attribute Directives: Used to change the appearance or behavior of an element (e.g., [ngClass], [ngStyle]).
5. Modular Development
- Applications are divided into modules (NgModules) that group related components, directives, services, and pipes.
- Facilitates lazy loading for performance optimization.
6. Reactive Programming with RxJS
- Angular integrates with RxJS for reactive programming.
- Enables handling asynchronous events, streams, and complex data flows effectively.
7. Router for SPA
- Angular Router provides powerful navigation and routing features, including:
- Nested routes.
- Lazy loading of modules.
- Guards to control access to routes.
8. Built-In Form Handling
- Template-Driven Forms: Easier to use for simple forms.
- Reactive Forms: More flexible and suited for dynamic or complex forms.
9. TypeScript Integration
- Built using TypeScript, offering:
- Static typing for catching errors at compile time.
- Advanced features like interfaces, generics, and decorators.
- Enhanced tooling support (e.g., IntelliSense, autocompletion).
10. Ahead-of-Time (AOT) Compilation
- Compiles the application during the build process, resulting in:
- Faster rendering.
- Smaller bundle sizes.
- Fewer runtime errors.
11. Angular CLI (Command-Line Interface)
- Simplifies development tasks such as scaffolding components, services, and modules.
- Provides tools for testing, building, and deploying applications.
12. Testing Support
- Built-in support for unit testing (Jasmine, Karma) and end-to-end testing (Protractor, Cypress).
- Encourages test-driven development.
13. Cross-Platform Development
- Angular supports building web, mobile, and desktop applications with a consistent codebase.
- Can be extended to create Progressive Web Applications (PWAs).
14. Internationalization (i18n)
- Built-in tools for supporting multiple languages and locales.
- Allows easy translation of content in applications.
15. Angular Universal
- Enables server-side rendering (SSR) for improved performance and SEO.
- Renders applications on the server and serves fully rendered pages to the client.
16. Angular Material
- A UI component library based on Google’s Material Design guidelines.
- Provides pre-built, customizable components for rapid development.
17. Security
- Prevents common vulnerabilities like Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF).
- Sanitizes inputs and templates automatically.
Angular’s comprehensive feature set makes it ideal for creating highly interactive, scalable, and maintainable web applications.
