About RxJS

What is RxJS?

RxJS is the reactive extensions library for JavaScript. It's a library for reactive programming using Observables, to make it easier to compose asynchronous or callback-based code. RxJS 6 is a rewrite of Reactive-Extensions/RxJS with better performance, better modularity, better debuggable call stacks, while staying mostly backwards compatible, with some breaking changes that reduce the API surface.  Version 7 is currently in public beta, but is currently used by Google in production.  To learn more about RxJS, please come to the conference or visit the documentation at is also an amazing resource for learning RxJS in preparation for RxJS Live! On Air.

Welcome & Intros


Ben Lesh - RxJS 7 & The Future of RxJS

09:15 am -

10:30 am

RxJS 7 is here. The future of RxJS is bright! Ben will give us a preview into the RxJS Roadmap for 2021 and beyond.


Deborah Kurata - RxJS in Angular: Pipeline Patterns

10:30 am -

11:00 am

Getting just the right combination of operators in an RxJS pipeline can seem like magic. But peek behind the curtain, and you'll see familiar patterns emerging.

In this talk, we'll examine several common RxJS pipelines for retrieving and processing data in Angular. We'll leverage Subjects, creation functions, higher order mapping and combination operators to implement real world scenarios.


By the end of this talk you'll wield the magical power of RxJS pipelines!

Zack DeRose - Visualizing the Timeline: Simplifying and Diagraming to Make Sense of RxJS

11:00 am -

11:30 am

Testing complex async code can be challenging. But, since we’re using RxJS, there are utilities and patterns that can help us tremendously.

In this talk, we’ll cover the various ways you can test your RxJS code, including how to effectively use the TestScheduler with ASCII marble diagrams to virtualize time, which gives us fast, deterministic tests.


Estefania Garcia Gallardo & Carlos Caballero - The power of RxJS: Building Flappy Bird in TypeScript

11:30 am -

12:00 noon 

To introduce reactive programming with RxJS, we will be building the famous Flappy Bird minigame. We will cover everything from the basic concepts of reactive programming (observables, observers, subscriptions etc) to an advanced use of RxJS operators, as well as the latest versions of powerful web technologies like TypeScript and Pixi.js

Lamis Chebbi - Healthy recipes using RxJS in Angular

01:00 pm -

01:45 pm

In this talk I will walk you through some common use cases in an Angular application many developers have experienced or can face in the future, and the implementation to put in place to achieve it in a reactive, clean, performant and readable way using RxJS

Jan-Niklas Wortmann - A Practical Guide for Testing Observables

01:45 pm -

02:15 pm

Hands down, testing Observables is hard. Even though RxJS comes with marble testing, that does not necessarily make it easier. In this talk you will learn very practical methods to test your RxJS code in an efficient and sustainable way and in the end, you probably don’t even need marble testing.

Tane Piper - How to Publish your own RxJS Libraries

02:15 pm -

02:45 pm

This talk will cover -

- How to set up the repository with NX using Github Actions to publish code to NPM 

- How to add a library and an operator - will briefly cover how the operator was created

- How to create a new Observable

- How to publish the documentation and make developers happy


Coffee Break

Josep Sobrepere - React-RxJS: Bringing Reactivity to React

03:15 pm -

04:15 pm

Seven years ago React taught us the value of using composable and declarative entities for describing our user interfaces. Wouldn't it be nice to also use composable and declarative entities to describe the dynamic behaviour of our domain state?


That's precisely why React-RxJS was created. In this talk, we demonstrate how this approach can greatly improve the performance and the maintenance of certain React applications, along with the challenges we've encountered along this journey.

Younes Jaaidi - What Happens When You Cancel an HTTP Request?

04:15 pm - 

04:45 pm

With reactive libraries like RxJS, we got used to easily canceling requests on the client-side… but what really happens on the back-end? Is the request really canceled? Did we really improve the app’s performance and reduce cloud costs? Or did we just trigger some crazy chaos?


Let’s dig deeper into how request cancelation works from the front-end to the back-end and how we can leverage reactive frameworks and libraries like Angular, RxJS, and NestJS to boost performance and reduce costs from the front-end to the database with some reactive programming.

Panel Discussion - RxJS Community Partners

04:45 pm -

05:00 pm

We will have a short panel discussion with our Community Partners in Asia


Matthew Podwysocki  - Going Beyond the Observable

05:00 pm - 

05:30 pm

In the past we've talked about Observables and how they're really good for handling events and asynchronous programming.  In this talk, we'll go beyond the Observable, to look at the overall landscape of asynchronous landscape, where Observable fits, and well, where it might not.


To do that, we need to explore the asynchronous world, both single value and multi-value, push versus pull and hybrid approaches such as push-pull and pull-push.  From this, we'll introduce both the AsyncIterable and AsyncObservable, both as implemented in IxJS, the partner library to RxJS, which implements these to open up a new world of possibilities.

Next Workshop - July 29-30, 2021

RxJS Basics and Beyond
(by Ben Lesh)

This workshop starts off basic but dives deep, but by the end of the day gets very far into strategies and patterns you can use with RxJS to build applications anywhere JavaScript runs


This is a framework-agnostic class. We will talk about React, Angular, Node and others as we learn the fundamentals and hidden secrets of RxJS, starting with subscriptions, going through multicasting, creating custom operators, testing strategies and more.


The workshop will be run at a pace pursuant to the attendees' abilities, and we'll make sure that everyone gets a lot out of the course whether they're deeply knowledgable or new to RxJS.


Because this is an RxJS conference, please bring your advanced questions and scenarios to discuss at the end of the workshop.
