Angular Signals In Depth (Angular 20)

Explore the Future of Angular Development with Angular Signals!

Discover a modern approach to building Angular applications using Angular Signals, a revolutionary feature offering a new paradigm for reactive programming. Learn how Signals are gradually replacing RxJs in Angular, streamlining development and improving performance.

This course provides a comprehensive guide to crafting Angular applications with minimal reliance on RxJs, focusing on the power and simplicity of Signals.

Course Overview:

This hands-on course will guide you through building a small Angular application from the ground up, leveraging Signals and the new signal-based component authoring API (avoiding the older decorator-based approach). You'll gain practical experience with common signal-based design patterns essential for modern Angular development.

We'll cover:

• Deep Dive into Angular Signals: Understand the core concepts of Signals, why they're beneficial, and master the three fundamental primitives: Signals, Computed Signals, and Effects.
• Signal-Based Component API: Learn to utilize the new signal-based component API for efficient and reactive component development, including handling inputs and outputs.
• Complete CRUD Example: Build a fully functional CRUD (Create, Read, Update, Delete) application using Signals and a local backend.
• HTTP Requests with Optional RxJs: Explore various methods for making HTTP requests in Angular, including using async/await and working with the Angular HTTP client, with and without RxJs.
• Robust Error Handling: Implement effective error handling strategies using Signals to ensure a stable and user-friendly application.
• Loading Indicators: Implement dynamic loading indicators using Signals to provide visual feedback to users.
• User Message Handling: Learn how to effectively manage and display user messages using a signal-based approach.
• Master-Detail Scenarios: Develop efficient master-detail interfaces using Signals for displaying and managing related data.
• Stateful Signal-Based Services: Create reusable and maintainable stateful services using Signals.
• Angular Authentication: Implement frontend authentication using Signals and functional guards.
• RxJs Interoperability: Discover how to seamlessly integrate RxJs with Signals for specific edge cases.
• Signal-Based View Queries: Utilize viewChild, viewChildren, contentChild, and contentChildren for powerful view manipulation.
• Bi-directional Binding: Master bi-directional binding with Signals and the model() API.

What You Will Learn:

By the end of this course, you will:

• Confidently use Signals to build modern Angular applications with the new signal-based component authoring API.
• Become proficient in using async/await for asynchronous operations and minimize your reliance on RxJs.
• Understand and implement common signal-based application patterns for efficient and reactive development.
• Gain a solid understanding of the core concepts of Signals and how to apply them to build Angular applications from start to finish.
