• Explore the latest Angular features
• Learn about various RxJS operators and techniques

Book Description
RxJS is a powerful reactive extension for JavaScript, specializing in asynchronous and event-driven programming. This book serves as a comprehensive, step-by-step guide to learning RxJS and reactivity, helping you navigate reactive patterns, efficient data management, and the streamlined implementation of common features with minimal code.
This second edition aligns with the latest version of Angular, introducing new reactive patterns based on Angular Signals, which play a pivotal role in enabling fine-grained reactivity within Angular and enhancing change detection and user interface rendering. Throughout the book, you’ll construct a complete application that incorporates the latest Angular features, such as standalone components, new built-in control flow, deferrable views, and more. You’ll focus on cultivating skills to handle data reactively, thus improving the application's overall quality, user experience, and developer productivity. As you progress, the book covers best practices for testing asynchronous streams and optimizing app performance.
By the end of this RxJS and Angular book, you’ll not only be able to develop Angular applications by implementing reactive patterns, but also grasp all the best practices, ensuring a well-rounded understanding of RxJS within the Angular framework.
What you will learn

• Get to grips with RxJS core concepts such as Observables, subjects, and operators
• Use the marble diagram in reactive patterns
• Delve into stream manipulation, including transforming and combining them
• Understand memory leak problems using RxJS and best practices to avoid them
• Build reactive patterns using Angular Signals and RxJS
• Explore different testing strategies for RxJS apps
