This section lays the foundation for your journey into Angular development. You’ll explore the core building blocks of Angular, understand how Angular applications are structured, and get familiar with key concepts like components, modules, templates, and data binding. Through easy-to-follow explanations and hands-on examples, you'll learn how Angular works behind the scenes and why it’s one of the most popular frameworks for building modern web applications. By the end of this section, you'll be ready to create your first Angular component and understand how different parts of an Angular app work together.

Before diving deep into Angular, it's crucial to understand TypeScript—the programming language that powers Angular. This module introduces you to the core features of TypeScript and explains how it enhances JavaScript by adding strong typing, interfaces, classes, and modern ES6+ features. You'll learn how TypeScript helps write cleaner, more reliable code, and why it’s essential for developing Angular applications. Through hands-on examples, you'll build the confidence to use TypeScript effectively in real Angular projects.

Components and templates are at the heart of every Angular application. This module provides a comprehensive introduction to how Angular apps are built using reusable components and how they interact with the user interface through templates. You’ll learn how to create, organize, and communicate between components using decorators, data binding, and lifecycle hooks. We'll also explore how Angular templates use directives and expressions to dynamically update the view based on user interaction and data changes. By the end of this module, you’ll be able to build custom UI components, connect them with data and events, and structure your application in a modular, maintainable way.

Directives and pipes are powerful features that make Angular templates dynamic and user-friendly. This module introduces you to Angular directives, which allow you to manipulate the DOM, control rendering, and apply logic in your templates. You'll also explore pipes, which help you format data directly in the view without changing the underlying data. You’ll learn how to use built-in structural directives like *ngIf and *ngFor, apply attribute directives like ngClass and ngStyle, and even create custom directives for reusable logic. On the other hand, you'll discover how pipes transform data for display—like formatting dates, currencies, or filtering lists—and how to create custom pipes for your own use cases. By the end of this module, you’ll be able to control the structure and style of your templates and transform data on the fly using Angular’s directive and pipe system.

Services and Dependency Injection (DI) are essential for writing clean, modular, and testable Angular applications. This module will introduce you to the concept of services, which are used to share logic, data, and functions across multiple components without duplication. You’ll learn how to create and inject services using Angular's built-in dependency injection system, allowing your components to stay focused on the UI while services handle tasks like data fetching, business logic, logging, and state management. By the end of this module, you’ll be able to build reusable and maintainable services, understand the @Injectable decorator, and configure service providers correctly for application-wide or component-level usage.

Routing is what allows Angular applications to behave like multi-page apps while actually being single-page applications (SPAs). This module introduces you to Angular’s powerful routing system, which lets users navigate between views, load different components based on URLs, and pass data through routes. You’ll learn how to configure routes, create navigation links, and handle route parameters and guards. This makes your Angular app feel more like a traditional website—fast, responsive, and intuitive to navigate. By the end of this module, you’ll be able to build Angular applications with multiple views, implement navigation logic, and manage route access with guards.

Forms are a crucial part of any web application that requires user interaction. In Angular, you have two powerful ways to handle forms: Template-driven forms and Reactive forms. This module provides an in-depth understanding of both approaches and teaches you how to manage user input, validation, and dynamic forms. You’ll start by learning template-driven forms, which are simpler to set up and ideal for simple scenarios. Then, you’ll dive into reactive forms, which offer more control, flexibility, and are suited for more complex forms and scenarios. Throughout the module, you'll also explore form validation, both built-in and custom, to ensure that your forms meet the required standards. You’ll also learn about FormGroup, FormControl, and FormBuilder to handle forms programmatically in Reactive forms. By the end of this module, you’ll be confident in creating, validating, and submitting forms in Angular, ensuring smooth user interactions and seamless application workflows.

In modern web applications, interacting with backend services is essential. This module introduces you to Angular’s HTTP Client, which makes it easy to send and receive data from RESTful APIs. You’ll learn how to perform HTTP requests, such as GET, POST, PUT, and DELETE, and handle responses in a clean and structured way. You’ll also understand how to work with observables and handle errors efficiently, ensuring your app remains responsive and stable. By the end of this module, you will be able to connect your Angular application to external APIs, retrieve and send data, and manage the flow of HTTP requests and responses in a way that supports real-world applications.

RxJS (Reactive Extensions for JavaScript) is a library for reactive programming using Observables. It's used extensively in Angular to handle asynchronous data streams such as HTTP requests, user input events, WebSocket messages, etc. RxJS provides operators to transform, filter, combine, and manipulate streams of data. It's built around the idea of reacting to data as it arrives, instead of actively fetching or polling for it. An Observable is a stream of data that you can subscribe to. Think of it as a way to manage asynchronous data (like promises, but more powerful).

State management is a critical part of building large-scale, maintainable Angular applications. In this module, you’ll be introduced to NgRx, a powerful library that provides a reactive state management solution for Angular apps, inspired by Redux. You’ll learn how NgRx helps you manage global state in your app by using a store that holds the state, and a set of actions and reducers to modify that state in a predictable and testable manner. This ensures your app’s state remains consistent, even as it grows in complexity. By the end of this module, you'll understand how to use the NgRx store, dispatch actions, and select state in a way that keeps your app’s data flow clear, predictable, and scalable.

Angular Material is a UI component library for Angular applications that implements Google’s Material Design specifications. It provides a set of well-designed, accessible, and responsive UI components out-of-the-box. It helps developers build consistent and professional-looking interfaces quickly without having to design from scratch. UI libraries are collections of reusable UI components and design tools built specifically for Angular or compatible with it. Besides Angular Material, there are many other UI libraries developers can choose from based on design preferences and project needs.

Testing is an essential part of building robust Angular applications. This module introduces you to the world of unit testing and end-to-end (E2E) testing in Angular, using tools like Jasmine, Karma, and Protractor (or Cypress for modern apps). You’ll learn how to write tests for Angular components, services, pipes, and other application logic. The goal is to ensure your app works as expected and can easily be maintained and refactored in the future. Through real-world examples and hands-on exercises, you'll gain confidence in using Angular’s TestBed for unit tests, understanding the basics of mocking dependencies, and running E2E tests to simulate user interactions. By the end of this module, you'll be able to create a test suite that validates the functionality of your Angular app, ensuring quality, reliability, and preventing regressions.

Performance Optimization in Angular refers to a set of techniques and best practices used to enhance the speed, responsiveness, and efficiency of Angular applications. The goal is to ensure that the application runs smoothly, consumes minimal resources, and provides a fast and seamless user experience. Angular applications, especially as they grow in size and complexity, can experience performance bottlenecks due to factors like frequent change detection cycles, large initial bundle sizes, or inefficient rendering of dynamic content. Performance optimization focuses on identifying and eliminating these bottlenecks.

Deploying your Angular application and following best practices is essential to ensure that your app runs efficiently, securely, and is easy to maintain as it grows. This module will guide you through the process of deploying your Angular application to different environments, including production and cloud-based platforms, while also introducing you to the best practices for building scalable, performant Angular apps. You’ll learn how to optimize your app for production, handle configuration settings, and ensure secure deployments. Additionally, we’ll cover code splitting, lazy loading, caching, and other techniques to boost performance. The module also focuses on coding standards, modular architecture, and testing, helping you build apps that are not only functional but also maintainable and easy to scale. By the end of this module, you’ll be equipped with the knowledge to deploy your Angular app seamlessly and follow industry-standard best practices to ensure top-notch quality and performance.

Angular 20 introduces the stable Signals API for fine-grained reactivity and better state management. It offers zoneless change detection (preview), improving performance without relying on Zone.js. Incremental hydration and enhanced SSR make apps load faster and more SEO-friendly. New template control flow syntax (@if, @for, @switch) replaces older structural directives. Resource APIs (resource(), httpResource()) simplify async data handling with caching and errors. Standalone components, improved CLI builds, and modern TypeScript support boost developer productivity.
