Angular provides built-in support for lazy loading, making it easy to implement. Developers can organize their application into feature modules and load them asynchronously when required.


  • Reactive Forms


Angular’s reactive forms offer a more robust and scalable approach to form handling compared to template-driven forms. Reactive forms are based on reactive programming principles and leverage the power of reactive extensions (RxJS) to manage form data and handle complex validation scenarios. With reactive forms, developers can create dynamic forms, handle form input changes, implement custom validators, and perform advanced form manipulation.


  • Custom Directives


Directives are a key aspect of Angular’s architecture, enabling developers to extend HTML with custom behaviors. While Angular provides several built-in directives, such as ngIf and ngFor, developers can also create their own custom directives. Custom directives offer a powerful way to encapsulate complex behavior into reusable components, enhancing code maintainability and modularity. Whether you need to create attribute directives or structural directives, Angular’s directive API provides the flexibility to implement advanced functionalities.


  • Advanced Routing


Angular’s powerful routing module offers much more than simple navigation between views. Developers can leverage advanced routing features to handle complex scenarios like route guards, lazy-loaded routes, route resolvers, and child routes. Route guards allow developers to control access to specific routes based on authentication or user roles. Route resolvers help in fetching data before a route is activated, ensuring that the route’s dependencies are resolved beforehand. With advanced routing, developers can create highly interactive and secure Angular applications.


  • Performance Optimization


As applications grow in complexity, performance optimization becomes crucial. Angular provides various techniques to enhance the performance of an application. AOT (Ahead-of-Time) compilation can significantly reduce the bundle size and improve the initial load time. Change detection strategies like OnPush enable developers to optimize rendering by selectively triggering change detection based on component input changes. Developers can also leverage Angular’s built-in profiler, the Angular DevTools, to identify performance bottlenecks and optimize critical areas of their application.



  • Dependency Injection


Dependency injection (DI) is a core concept in Angular that promotes loose coupling and modular design. While DI is commonly used for injecting services into components, it can be extended to other areas like directives and pipes as well. Advanced usage of DI includes hierarchical injectors, custom providers, and conditional injection. Understanding the intricacies of DI enables developers to write cleaner, more maintainable code and facilitates unit testing.


  • Internationalization and Localization


Angular provides robust support for internationalization (i18n) and localization (l10n) out of the box. Developers can easily create multi-language applications by leveraging Angular’s i18n capabilities. By marking translatable text in templates, extracting messages, and generating translation files, developers can build applications that cater to users from different regions. Angular also supports dynamic language switching and advanced localization techniques, making it easier to provide a localized experience for users worldwide.


  • Server-side Rendering (SSR)


Angular Universal, the server-side rendering (SSR) solution for Angular, enables developers to render Angular applications on the server and send fully rendered pages to the client. SSR offers benefits like improved initial load time, better search engine optimization (SEO), and enhanced user experience, especially for users on slow networks. Advanced SSR techniques include state transfer, handling dynamic data, and optimizing server-side rendering for performance.


  • Advanced Testing Techniques


Testing is a crucial aspect of software development, and Angular provides a robust testing infrastructure. Developers can go beyond basic unit tests and explore advanced testing techniques like component testing, integration testing, and end-to-end (e2e) testing using tools like Karma, Jasmine, and Protractor. Advanced testing techniques also include mocking dependencies, testing complex data flows, and generating code coverage reports. Comprehensive testing ensures the stability and reliability of Angular applications.


  • PWA (Progressive Web Apps) Support


Progressive Web Apps combine the best features of web and mobile applications, providing an engaging and reliable user experience. Angular offers built-in support for creating Progressive Web Apps, including features like service workers, app manifest, and offline caching. By leveraging Angular’s PWA capabilities, developers can transform their applications into installable, offline-ready experiences that work seamlessly across different devices and platforms.



  • Web Workers


Angular allows developers to leverage web workers to offload expensive tasks to background threads, improving overall performance and responsiveness. Web workers enable concurrent processing by running scripts in the background without blocking the main UI thread. With Angular, developers can easily create and communicate with web workers, enabling the execution of complex computations, data processing, and heavy calculations without impacting the user interface.


  • Reactive Extensions (RxJS)


RxJS is a powerful library for reactive programming that Angular heavily relies on. By embracing the principles of observable streams and operators, developers can handle asynchronous operations, event handling, and complex data transformations more effectively. With RxJS, developers can create responsive, event-driven applications, implement advanced caching strategies, and handle complex scenarios like debounce, throttling, and combining multiple streams of data.


  • Dynamic Component Loading


Angular provides the capability to dynamically load components at runtime, offering flexibility and extensibility to applications. Developers can take advantage of this feature to create dynamic and customizable user interfaces. Dynamic component loading is particularly useful when dealing with scenarios like user-generated content, plugins, or dynamically changing UI requirements. It allows developers to load components on demand, saving initial load time and enabling a more interactive user experience.


  • Angular Material


Angular Material is a UI component library developed and maintained by the Angular team. It provides a set of pre-built, customizable components following Material Design guidelines, offering a consistent and visually appealing user interface. Advanced usage of Angular Material includes theming, custom component styling, and creating complex layouts. By leveraging Angular Material, developers can save time, ensure UI consistency, and focus on building core application logic.


  • Advanced State Management


As applications grow in complexity, managing state across components becomes crucial. Angular provides various options for advanced state management, including libraries like NgRx and Akita. These libraries leverage concepts like Redux and reactive programming to handle complex state management scenarios, including immutable state, time-travel debugging, and advanced data flow patterns. Advanced state management libraries enable developers to create scalable, maintainable applications with a clear separation of concerns.


  • Cross-platform Development


Angular allows developers to build not only web applications but also cross-platform desktop and mobile applications using frameworks like Electron and Ionic. Electron enables developers to package Angular applications as standalone desktop applications for Windows, macOS, and Linux. Ionic leverages Angular to create mobile applications that run on multiple platforms like iOS and Android.
