This Course In a Nutshell 🚀

Angular Signals are revolutionizing the way we build applications. If you've been keeping up with the latest in Angular, you know that RxJs is gradually taking a backseat, making room for this powerful new feature. But what does an Angular application look like when it leverages Signals and minimal RxJs? 🤔

  • The Essence: We're diving deep into the world of Angular Signals to show you how to create modern applications with this new API.
  • Practical Approach: By building a full application from scratch, we'll cover essential signal-based UI patterns that you'll use time and time again.
  • Hands-On Learning: You'll get hands-on experience with real-world scenarios, including CRUD operations, HTTP requests, and more.

Course Overview 📚

We're breaking down the course into digestible segments to ensure you understand each part before moving on to the next:

  1. Introduction to Signals: We'll start by demystifying what signals are and why they're a game-changer for Angular applications.
  2. Core Primitives: A detailed exploration of the three fundamental signal types: signals, computed signals, and effects.
  3. Building an Application: Using the new signal-based component API, we'll construct a full application, avoiding the old decorator-based approach.
  4. Real-World Features: We'll cover implementing essential features like loading indicators, user messages, master-detail scenarios, and stateful services.
  5. Authentication: You'll learn how to handle authentication on the frontend with signals and functional guards.
  6. RxJs Interoperability: For cases where RxJs is still your best tool, we'll show you how to integrate it seamlessly with signals.

Course Review Synthesis

Pros

  • Comprehensive for All Levels: The course is beneficial not only for newcomers but also for seasoned Angular developers, providing insights into the latest framework features and syntax, such as signals, standalone components, and functional guards and resolvers.
  • Ease of Understanding: The content is easy to understand, very clear, and well-explained, which makes it accessible to those who may have found Angular challenging in the past.
  • High-Quality Instruction: The instructor's teaching style is excellent, making angular concepts easier to grasp for learners. This approach likely attracts developers who were previously apprehensive about using Angular.
  • Well-Structured and Managed: The course has a well-structured and managed format, clarifying edge cases and scenarios with brilliant explanations.

Cons

  • Bias Towards Certain Techniques: There seems to be an emphasis on using 'bare' JavaScript and third-party libraries over the established RxJS infrastructure and tools, which may not align with best practices for all use cases.
  • Incomplete Coverage of Signals: The course does not fully explain how signals work within their graph or provide a clear understanding of proper usage.
  • Error Handling with Signals: Specifically in lesson 66, the approach to handling errors with try-catch is misleading if applied directly to a signal block without considering its placement within an effect.

Additional Feedback

  • Real-World Application: Users have expressed the need for real-world examples that demonstrate when and how to use signals versus observables, particularly differentiating state-like tasks from event-like tasks.
  • Quality Assurance: Angular University's reputation for quality course development is reaffirmed with this offering on Angular Signals.

Recommendations

  • Revise RxJS Content: To ensure a balanced approach that includes the use of RxJS alongside new features like signals.
  • Enhance Signal Graph and Usage Explanation: To provide a more comprehensive understanding of how signals operate internally and their proper usage within applications.
  • Improve Error Handling Instruction: Specifically in relation to handling errors within signal blocks, ensuring that the explanation is accurate and contextually relevant.

In conclusion, this course on Angular Signals is highly recommended for both new and experienced developers. It is well-crafted, clear, and structured, offering valuable insights into the latest Angular features. However, it would benefit from addressing the mentioned areas to ensure a complete understanding of signals and their role in Angular applications alongside the use of RxJS.
