Overview

This intermediate Angular course helps you transform a foundational application into a scalable, API-connected, production-ready system. You’ll integrate real backend services, manage asynchronous data using RxJS and Angular Signals (v18–21), structure maintainable component architectures, and introduce testing practices that improve reliability. The course begins with hands-on HTTP integration, including CRUD operations, interceptors, and error handling. You’ll then strengthen your understanding of reactivity and shared state using RxJS operators, Signals, and service-based state containers. Next, you’ll design scalable component communication patterns, apply dependency injection effectively, and organize feature-based architectures for large applications. Finally, you’ll implement unit and component testing, adding structured test coverage to real project features. By the end, your project evolves into a fully functional, data-driven Angular application built with scalability and maintainability in mind. By the end, you will: • Integrate backend APIs using Angular HttpClient and interceptors • Manage async data and shared state with RxJS and Signals • Design scalable component and feature-based architectures • Apply dependency injection patterns effectively • Write unit and component tests for services and UI logic This course is ideal for: • Developers who completed Angular fundamentals • Frontend engineers building data-driven apps • Developers preparing for mid-level roles • Learners targeting enterprise Angular projects Build Angular applications ready for real-world scale and reliability.

Syllabus

HTTP, APIs & Data Handling

This module focuses on connecting Angular applications to real backend APIs using the HttpClient. Learners perform CRUD operations, handle errors, implement retry strategies, and use interceptors for authentication, caching, and logging. They also apply API integration patterns such as pagination, filtering, real-time UI updates, and service-based design. The module concludes with a project milestone where learners integrate CRUD features and implement an end-to-end UI + API workflow.

State Management & Data Flow in Angular (Angular 21)

This module focuses on managing application state in a scalable and predictable way. You will examine component-level state, shared state through services, and reactive patterns using RxJS Observables, Subjects, and BehaviorSubjects. The module also introduces structured data flow patterns, including smart and presentational components, and provides an overview of store-based state management concepts. You will design a structured state architecture that ensures consistency and maintainability across your application.

Authentication & Authorization in Angular 21

This module covers securing Angular applications through authentication and authorization strategies. You will explore authentication fundamentals, token-based authentication, route guards, HTTP interceptors, and role-based access control. Practical implementation includes login and logout flows, persistence of authentication state, and real-world integration patterns. By the end, you will implement a secure authentication system that protects routes and APIs while managing user roles effectively.

Performance Optimization & Change Detection in Angular 21

This module addresses performance tuning and advanced Angular optimization strategies. You will analyze Angular’s change detection mechanisms, compare detection strategies, and identify common performance bottlenecks. The module introduces template and component optimization, lazy loading, code splitting, signals, zoneless concepts, and performance monitoring practices. You will optimize your application using modern Angular techniques to improve responsiveness, scalability, and runtime efficiency.
