## Install

```sh

go get -u github.com/jjeffcaii/reactor-go

```

## Example

### Mono

```go

package mono_test

import (

	"context"

	"fmt"

	"github.com/jjeffcaii/reactor-go"

	"github.com/jjeffcaii/reactor-go/mono"

)

func Example() {

	gen := func(ctx context.Context, sink mono.Sink) {

		sink.Success("World")

	}

	mono.

		Create(gen).

		Map(func(input reactor.Any) (output reactor.Any, err error) {

			output = "Hello " + input.(string) + "!"

			return

		}).

		DoOnNext(func(v reactor.Any) error {

			fmt.Println(v)

			return nil

		}).

		Subscribe(context.Background())

}

// Should print

// Hello World!

```

### Flux

```go

package flux_test

import (

	"context"

	"fmt"

	"github.com/jjeffcaii/reactor-go"

	"github.com/jjeffcaii/reactor-go/flux"

	"github.com/jjeffcaii/reactor-go/scheduler"

)

func Example() {

	gen := func(ctx context.Context, sink flux.Sink) {

		for i := 0; i < 10; i++ {

			v := i

			sink.Next(v)

		}

		sink.Complete()

	}

	done := make(chan struct{})

	var su reactor.Subscription

	flux.Create(gen).

		Filter(func(i interface{}) bool {

			return i.(int)%2 == 0

		}).

		Map(func(input reactor.Any) (output reactor.Any, err error) {

			output = fmt.Sprintf("#HELLO_%04d", input.(int))

			return

		}).

		SubscribeOn(scheduler.Elastic()).

		Subscribe(context.Background(),

			reactor.OnSubscribe(func(s reactor.Subscription) {

				su = s

				s.Request(1)

			}),

			reactor.OnNext(func(v reactor.Any) error {

				fmt.Println("next:", v)

				su.Request(1)

				return nil

			}),

			reactor.OnComplete(func() {

				close(done)

			}),

		)

	<-done

}

// Should print:

// next: #HELLO_0000

// next: #HELLO_0002

// next: #HELLO_0004

// next: #HELLO_0006

// next: #HELLO_0008

```
