Unlock the power of Angular by mastering reactive programming with our course, "Reactive Angular Course (with RxJs)." This course is your comprehensive guide to understanding and applying common design patterns and some anti-patterns in Angular development. Designed for developers eager to leverage plain RxJs for crafting responsive applications, this course ensures a practical learning experience with a running GitHub repository containing finished code and starting points for various sections.
Why Learn Reactive Angular?
The course addresses a crucial question for developers: How much can you achieve in Angular using only plain RxJs? Without the need for external state management libraries, the techniques taught here are ideal for a vast range of applications, particularly enterprise-level projects. You'll discover the potent combination of Angular and RxJs in designing and developing both service and view layers, while understanding the merits and challenges of the reactive approach.
These simplified state management techniques are efficient and sufficient for many applications, promoting them as a first-choice solution before considering robust state management libraries like NgRx.
Course Overview
We begin by examining a small Angular application written in imperative style, highlighting some inherent issues. Subsequently, you'll refactor this application, learning step-by-step to adopt a reactive style.
Throughout the course, you'll gain detailed insights into every RxJs operator used. Initially, we'll focus on a purely stateless solution, eventually enhancing the user experience with simple RxJs-only state management techniques, including handling application data and user authentication profiles.
A key feature of lightweight state management is understanding RxJs behavior subjects, which we'll explore in depth. You'll also learn step-by-step solutions for common UI functionalities like loading indicators and error messages in a reactive style.
