# Reactor Kotlin Extensions

[![Join the chat at https://gitter.im/reactor/reactor](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/reactor/reactor?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)

Add various extensions and adapters for Kotlin programming language. While Reactor Core, Reactor Addons and other Reactor libraries 

are designed to be Kotlin friendly with the use of `@Nullable` and carefully picked signature types, Kotlin developers might 

want to adapt the core functional programming API further.

# Maven Artifacts

With Gradle from repo.spring.io or Maven Central repositories (stable releases only):

```groovy

    repositories {

        //maven { url 'https://repo.spring.io/snapshot' }

        maven { url 'https://repo.spring.io/milestone' }

        mavenCentral()

    }

    dependencies {

        //implementation "io.projectreactor.kotlin:reactor-kotlin-extensions:1.3.0-SNAPSHOT"

        implementation "io.projectreactor.kotlin:reactor-kotlin-extensions:1.3.0-RC1"

    }

```

With Maven from Maven Central repositories (stable releases):

```xml

    io.projectreactor.kotlin

    reactor-kotlin-extensions

    1.3.0-RC1

```

Or from repo.spring.io with access to SNAPSHOT: 

```xml

...

    

        io.projectreactor.kotlin

        reactor-kotlin-extensions

        1.3.0-SNAPSHOT

    

...

    

        spring-milestones

        Spring Milestones

        https://repo.spring.io/milestone

    

    

        spring-snapshots

        Spring Snapshots

        https://repo.spring.io/snapshot

        

            true

        

    

```

# Quick Examples

Tuple destructure:

```kotlin

val (t1, t2, t3) = Tuples.of(O1, O2, O3)

assertEquals(t1, O1)

assertEquals(t2, O2)

assertEquals(t3, O3)

```

Convert, sum (*requires reactor-extra*) and test (*requires reactor-test*):

```kotlin

intArrayOf(2_000_000_000, 200_000_000) //sum overflows an Int

    .toFlux()

    .sum()

    .test()

    .expectNext(2_200_000_000)

    .verifyComplete()

```

Coordinating when two mono completes:

```kotlin

whenComplete("foo1".toMono(), "foo2".toMono())

    .test()

    .verifyComplete()

```
