How to think in streams and observables
Importance of reactive programming in modern apps
How to integrate RxJS with Angular
Differences between Signals and RxJS observables
What problems RxJS can solve in async workflows
How to create custom pipelines for your use cases
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.

Frequently Asked Questions
What is Mastering RxJS: A Compact Journey from Beginner to Pro?
In this course we'll cover the core concepts of RxJS—observables, operators, and subscriptions—and how to apply them in real-world applications. We'll build a hands-on reactive project that handles live async data streams. This project is valuable because it mirrors real production challenges and shows you exactly how RxJS can simplify complex async logic.
Who is this course for?
This course was produced for beginners and intermediate developers who are transitioning into reactive programming and want a clear, practical introduction to RxJS.
What if I don't like the course?
We offer a 30-day money-back guarantee, so if you're not satisfied with the course, you can request a refund within 30 days of purchase by sending us a message.
What is included in the course?
This course include 17 videos, totaling 88 minutes. You'll have access to every lesson video, textual lesson content, downloadable project code files, interactive IDE, and AI Tutor.
What are there prerequisites for this course?
You should have a basic understanding of Angular (components, services, and dependency injection) as well as solid JavaScript fundamentals (functions, arrays, promises, ES6+ syntax). No prior experience with RxJS is required, we'll cover it from the ground up within the Angular context.
How long will it take to complete the course?
The course offers flexibility, allowing you to learn at your own pace. Start, stop, re-watch anytime. It's expected that you'd spend approximately 2-3 hours going through the entire course materials.
Can I access the course on my mobile device?.
Yes, the course is fully responsive and can be accessed on your mobile device.
Is there a certificate upon completion of the course?
Yes, you can get a certificate by sending us a message.
Can I ask questions during the course?
Yes, you can ask questions in the comments section of each lesson, and our team will respond as quickly as possible. You can also ask us questions anytime through the community driven Discord channel.
Can I download the course videos?
No, the course videos cannot be downloaded, but they can be accessed online at any time.
What is the price of the course?
The course is currently priced at [$X USD]. Alternatively, you can access the complete course as part of the "newline Pro subscription", which costs $20/month.
How is this course different then other content available on RxJS?
This course is different because it doesn't just show you a laundry list of operators, it gives you a hands-on path to learning RxJS the right way. Many developers struggle with the steep learning curve, confusing operator choices, and unreadable chains scattered through Angular codebases. In this course we start simple and build gradually, always tying concepts back to real Angular use cases. Instead of drowning in abstractions, you'll see practical examples that emphasize clarity and maintainability, so RxJS becomes a tool you want to use rather than something you try to avoid.
