### Maven Dependency for Reactor Kotlin Extensions

Source: https://github.com/reactor/reactor-kotlin-extensions/blob/main/README.md

Include the reactor-kotlin-extensions library in your Maven project. This example uses a stable release version.

```xml
<dependency>
    <groupId>io.projectreactor.kotlin</groupId>
    <artifactId>reactor-kotlin-extensions</artifactId>
    <version>1.3.1</version>
</dependency>

```

### Maven Dependency with Snapshots and Milestones

Source: https://github.com/reactor/reactor-kotlin-extensions/blob/main/README.md

Configure Maven to use snapshot and milestone repositories for accessing pre-release versions of reactor-kotlin-extensions.

```xml
<dependency>
    <groupId>io.projectreactor.kotlin</groupId>
    <artifactId>reactor-kotlin-extensions</artifactId>
    <version>1.3.2-SNAPSHOT</version>
</dependency>

<repositories>
    <repository>
        <id>spring-milestones</id>
        <name>Spring Milestones</name>
        <url>https://repo.spring.io/milestone</url>
    </repository>
    <repository>
        <id>spring-snapshots</id>
        <name>Spring Snapshots</name>
        <url>https://repo.spring.io/snapshot</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>

```

### Tuple Destructuring in Kotlin

Source: https://github.com/reactor/reactor-kotlin-extensions/blob/main/README.md

Demonstrates how to destructure a Reactor Tuple into individual variables in Kotlin. Ensure Tuples are imported.

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

```

### Flux Summation and Testing

Source: https://github.com/reactor/reactor-kotlin-extensions/blob/main/README.md

Converts an integer array to a Flux, calculates the sum, and verifies the result using reactor-test. Requires reactor-extra for sum() and reactor-test for test().

```kotlin
intArrayOf(2_000_000_000, 200_000_000) //sum overflows an Int
    .toFlux()
    .sum()
    .test()
    .expectNext(2_200_000_000)
    .verifyComplete()

```

--------------------------------

### Gradle Dependencies for Reactor Kotlin Extensions

Source: https://github.com/reactor/reactor-kotlin-extensions/blob/main/README.md

Add the reactor-kotlin-extensions library to your Gradle project. Ensure you have mavenCentral() or repo.spring.io configured in your repositories.

```groovy
repositories {
    //maven { url 'https://repo.spring.io/snapshot' }
    mavenCentral()
}

implementation "io.projectreactor.kotlin:reactor-kotlin-extensions:1.3.1"

```

### Coordinating Mono Completions

Source: https://github.com/reactor/reactor-kotlin-extensions/blob/main/README.md

Waits for two Mono instances to complete using the whenComplete operator. This is useful for synchronizing asynchronous operations.

```kotlin
whenComplete("foo1".toMono(), "foo2".toMono())
    .test()
    .verifyComplete()

```
