Learning RxJava - Second Edition

Configuring RxJava and RxKotlin

In this chapter, we will also be using RxJava as well as an extension library called RxKotlin. For Gradle, add these two libraries as your dependencies as follows:

implementation 'io.reactivex.rxjava3:rxjava:3.0.0'implementation 'io.reactivex.rxjava3:rxkotlin:3.0.0-RC1'

For Maven, set them up like this:

<dependency>    <groupId>io.reactivex.rxjava3</groupId>    <artifactId>rxjava</artifactId>    <version>3.0.0</version></dependency><dependency>    <groupId>io.reactivex.rxjava3</groupId>    <artifactId>rxkotlin</artifactId>    <version>3.0.0-RC1</version></dependency>

With the configuration completed, we can now start coding using the Kotlin language. But first, let's review the basics of Kotlin.
