# Fan Out

Fan Out design pattern, using channels with generics.

## What problem does it solve?

Fan Out pattern is a software architecture pattern that involves distributing data (messages / payloads) from a single

sender (publisher) to multiple receivers (listeners).

Each recipient receives a copy of the message - if your `payload` is a pointer, that would violate the pattern. 

The Fan Out pattern is useful in situations where multiple components of a system need to `react` to the same `event` or

receive the same `data`.

This is a naive implementation of the Fan Out pattern, using channels and generics. 

In its shortest form, it looks like this:

```go

package mypack

func FanOut[T any](from <-chan T, to ...chan<- T) {

	for v := range from {

		for _, ch := range to {

			ch <- v

		}

	}

}

```
