Reactive Angular Course (with RxJs, Angular 19)

🎓 Reactive Angular Course (with RxJs, Angular 17)

Course Headline: Build Angular 17 Applications in Reactive style with plain RxJs - Patterns, Anti-Patterns, Lightweight State Management

This Course in a Nutshell 🔍

This course is a comprehensive guide to the most common design patterns (and some anti-patterns) that every Angular developer should master. Our goal is to equip you with the knowledge and skills to comfortably design and develop applications in Angular using only plain RxJs, without relying on any additional state management libraries like NgRx.

• Learn a suite of techniques that are highly adaptable for various applications, particularly enterprise solutions.
• Understand the intricacies of using RxJs for both service and view layers.
• Discover the advantages and pitfalls of the reactive approach, with a focus on simplified state management without extra libraries.

Course Overview 🌟

We start by examining a simple Angular application written in an imperative style, highlighting some common issues. Then, we'll refactor this application to implement it in a reactive style step-by-step, explaining each RxJs operator as we encounter it.

• Begin with a stateless solution and enhance the user experience by applying lightweight state management techniques.
• Cover essential RxJs operators from the ground up and provide detailed explanations of concepts like BehaviorSubject.
• Offer reactive solutions for common UI functionality such as loading indicators, error messages, and more.
