Overview

This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. In this comprehensive course, you'll dive into the fundamentals of RxJS, starting with setting up your environment and understanding its core principles. You'll explore key concepts like observables, operators, and the relationship between observers and observables, setting a solid foundation for building reactive applications. Through hands-on exercises, you will master essential operators, including map, filter, and error handling strategies, while learning how RxJS can handle asynchronous data streams more efficiently than promises. As the course progresses, you'll venture into advanced topics such as using subjects, combining observables with operators like combineLatest and forkJoin, and implementing debouncing and throttling techniques. This course also emphasizes practical usage by applying the skills learned to real-world projects, allowing you to integrate RxJS into modern web applications. By the end of the course, you will be able to confidently implement RxJS in your applications, handle complex data flows, create custom observables, and apply advanced reactive programming concepts to real-world projects.

Syllabus

Introduction

In this module, we will introduce you to the foundational concepts of RxJS and its importance in modern web development. You will also learn how to set up your development environment and project structure to begin coding with RxJS, as well as how to maintain clean code using tools like Prettier.

RxJS Basics

In this module, we will dive into the core concepts of RxJS, including observables, observers, and methods like of and from. You will learn how to work with these reactive constructs, build custom observables, and understand how RxJS handles asynchronous data streams in a more powerful way than promises.

Most Important Operators

In this module, we will explore the most important RxJS operators that will empower you to create dynamic and efficient data flows. You'll learn how to use operators like map, filter, and merge, and how to apply them in real-world scenarios like HTTP requests, error handling, and memory management.

Advanced RxJS

In this module, we will take your RxJS skills to the next level by exploring advanced operators and techniques. You will learn how to combine observables, control emissions, and debug your streams, all while solving practical exercises that challenge you to apply what you've learned.

RxJS Subjects

In this module, we will explore the powerful concept of RxJS subjects, including BehaviorSubject and ReplaySubject. You'll learn how to use these subjects to manage shared state, refactor complex observable chains, and apply the retry operator to handle transient errors.

What's Next?

In this module, we will conclude the course with homework tasks designed to solidify your understanding of RxJS. You’ll have the opportunity to apply the concepts and techniques learned in the course to real-world problems, setting you up for success in your future RxJS projects.
