Implementing Custom Operators in RxJava 1. Overview In this quick tutorial, we’ll show how to write a custom operator using RxJava. We’ll discuss how to build this simple operator, as well as a transformer – both as a class or as a simple function. 2. Maven Configuration First, we need… Continue Reading rxjava-custom-operators

RxJava 2 – Flowable 1. Introduction RxJava is a Reactive Extensions Java implementation that allows us to write event-driven, and asynchronous applications. More information on how to use RxJava can be found in our intro article here. RxJava 2 was rewritten from scratch, which brought multiple new features; some of… Continue Reading rxjava-2-flowable

RxJava StringObservable 1. Introduction to StringObservable Working with String sequences in RxJava may be challenging; luckily RxJavaString provides us with all necessary utilities. In this article, we’ll cover StringObservable which contains some helpful String operators. Therefore, before getting started, it’s advised to have a look at the Introduction to RxJava… Continue Reading rxjava-string

Observable Utility Operators in RxJava 1. Overview In this article, we’ll discover some utility operators for working with Observables in RxJava and how to implement custom ones. An operator is a function that takes and alters the behavior of an upstream Observable<T> and returns a downstream Observable<R> or Subscriber, where… Continue Reading rxjava-observable-operators

RxJava Tutorial RxJava is a Reactive Extensions implementation for Java environment. The library utilizes a combination of functional and reactive techniques that can represent an elegant approach to event-driven programming – with values that change over time and where the consumer reacts to the data as it comes in. RxJava… Continue Reading rxjava-tutorial

Converting Synchronous and Asynchronous APIs to Observables using RxJava2 1. Overview In this tutorial, we’re going to learn how to transform traditional synchronous and asynchronous APIs into Observables using RxJava2 operators. We’ll create a few simple functions that will help us discuss these operators in detail. 2. Maven Dependencies First,… Continue Reading rxjava-apis-to-observables

Dealing with Backpressure with RxJava 1. Overview In this article, we will look at the way the RxJava library helps us to handle backpressure. Simply put – RxJava utilizes a concept of reactive streams by introducing Observables, to which one or many Observers can subscribe to. Dealing with possibly infinite… Continue Reading rxjava-backpressure

RxJava Hooks 1. Overview In this tutorial, we’re going to learn about RxJava hooks. We’ll be creating short examples to demonstrate how the hooks work in different situations. 2. What are RxJava Hooks? As the name depicts, RxJava hooks allow us to hook into the lifecycle of Observable, _Completable, Maybe,… Continue Reading rxjava-hooks
