Deep dive into Reactive Java

Room 4A - Metrosoft

RxJava is prominent amongst only few options for doing reactive streams in Java. It is different than JDK Streams and CompletableFuture and, while this presentation will cover the differences, it seems to be the best option for coordination asynchronous tasks using simple and powerful api.

In this presentation we will not theorise but open up code editor and take a deep dive into code using RxJava.

First we will write simple application that consumes firehose of tweets directly from Twitter. You will learn how to filter, map and throttle them. Then we will look how asynchronous http client emits events into the stream. After this introduction we will write JavaFx based windowed app for posting tweets with asynchronous autocompletion of @mentions and downloading of profile pictures.

I hope this will be fun and at the end of the presentation we will have a working application.
