Dive into the world of RxJS with our intensive workshop designed to equip you with all the necessary knowledge and tools to harness the power of reactive programming:

Understanding RxJS Primitives: Uncover the difference between Subject and Observable, convert Promise APIs to Observable, and learn about optimal subscribing strategies and the execution context of Observables.

Concepts & Marble Diagrams: Explore useful RxJS learning tools, understand how to read marble diagrams, and delve into various observable and operator types.

Operator Groups: Get hands-on with transform operators, learn about filtering, completion, error handling, and explore the top 4 flattening operators.

Subjects: Understand the producer-consumer pattern with Observers and Subscribers and explore the basic Subject types including Subject and BehaviorSubject.

Reactive Building Blocks: Discover how to manage state with streams, notify with events, and execute logic based on state or events. We'll also discuss the difference between RxJS and Signals.

Custom Sections: Get practical with live-coding sessions in our repositories and in-depth code reviews to refine your understanding and application of RxJS.
