# Module kotlinx-coroutines-reactive
Utilities for [Reactive Streams](http://www.reactive-streams.org).
Coroutine builders:
| **Name** | **Result** | **Scope** | **Description**
| --------------- | ----------------------------- | ---------------- | ---------------
| [publish] | `Publisher` | [ProducerScope] | Cold reactive publisher that starts coroutine on subscribe
Suspending extension functions and suspending iteration:
| **Name** | **Description**
| -------- | ---------------
| [Publisher.awaitFirst][org.reactivestreams.Publisher.awaitFirst] | Returns the first value from the given publisher
| [Publisher.awaitFirstOrDefault][org.reactivestreams.Publisher.awaitFirstOrDefault] | Returns the first value from the given publisher or default
| [Publisher.awaitFirstOrElse][org.reactivestreams.Publisher.awaitFirstOrElse] | Returns the first value from the given publisher or default from a function
| [Publisher.awaitFirstOrNull][org.reactivestreams.Publisher.awaitFirstOrNull] | Returns the first value from the given publisher or null
| [Publisher.awaitLast][org.reactivestreams.Publisher.awaitFirst] | Returns the last value from the given publisher
| [Publisher.awaitSingle][org.reactivestreams.Publisher.awaitSingle] | Returns the single value from the given publisher
| [Publisher.openSubscription][org.reactivestreams.Publisher.openSubscription] | Subscribes to publisher and returns [ReceiveChannel]
Conversion functions:
| **Name** | **Description**
| -------- | ---------------
| [ReceiveChannel.asPublisher][kotlinx.coroutines.channels.ReceiveChannel.asPublisher] | Converts streaming channel to hot publisher
