Course introduction

Application demo

RxJS History

Signals and RxJS

Application setup

Learn the fundamentals of reactive programming by exploring asynchronous JavaScript, Angular signals, and setting up a foundational Angular app to prepare for advanced RxJS concepts.

Intro & Getting Started

Fetching and Displaying Data

Async Pipe

Operators

Filtering Data Part 1

Filtering Data Part 2

Learn to handle data streams using observables, operators, and subjects for efficient reactive programming.

Managing Streams, Operators, and Subjects

Infinite Scrolling

Higher Order Observables, SwitchMap operator

MergeMap operator

ConcatMap operator

ExhaustMap operator

Master higher-order RxJS operators like switchMap, mergeMap, concatMap, and exhaustMap to handle complex, concurrent, and sequential asynchronous data streams efficiently.

Higher-Order Observables

Composing with Higher-Order Operators

Final Words

Apply everything learned to implement an efficient, scalable search and infinite scrolling with clean, maintainable reactive pipelines.

Wrapping Up

In this course we dive into the world of RxJS and reactive programming. RxJS makes managing asynchronous data streams elegant and powerful, but the concepts of observables, operators, and subscriptions can be overwhelming without a clear path..

In just a few focused lessons we cover the essentials of observables, how to compose operators to transform data, and how to use RxJS in real applications. The course is concise, just the right length to get you productive quickly, and comes with full code examples, exercises, and step-by-step walkthroughs.

It's taught by Victor, who has years of experience building large-scale applications with RxJS and Angular, and has trained development teams on adopting reactive programming in production. The course distills real-world experience using RxJS in production apps into practical lessons you can immediately apply.

You'll walk away knowing not just *how* to use RxJS, but also *when* it makes sense, the trade-offs compared to promises and callbacks, and how it can solve everyday async challenges in your projects.

In this course we explore reactive programming with RxJS. It makes handling async data streams elegant and powerful, but its learning curve can feel steep without guidance.

Hi guys, my name is Victor Tignomirov, I'm a full-stack developer and I'll be

Throughout my career, I have seen several Angular code bases using rxjs and I

the same mistakes popping up over and over again.

After doing some research, I found out that I wasn't the only one who I've

That's why I decided to make this course, I want to share my knowledge and

In this course, we will build an application from scratch and while doing it,

learn new concepts and immediately apply them.

I will also share lots of tips and tricks and common mistakes that I have

By the end of this course, you will feel comfortable in writing reactive

The first module, we will go through a brief rxjs history, then we will make a

In the next module, we'll cover imperative versus declarative programming, we

how to think about our data in streams of data, we will have a look at what

We will also look at best practices and common pitfalls.

After that, we will learn how to combine multiple streams of data into a single

With a deep dive practical approach, we will learn how to pick the right one.

I hope you will enjoy this course as much as I enjoyed making it.
