import (

    commandbus "github.com/edwin-luijten/go_command_bus"

)

func main() {

    bus := commandbus.New()

    

    bus.RegisterHandler(&RegisterUserCommand{}, func(command interface{}) {

        cmd := command.(*RegisterUserCommand)

        

        fmt.Sprintf("Registered %s", cmd.Username)

A middleware has a handler and a priority.  

Where priority of 0 is the least amount of priority.  

```go

import (

    commandbus "github.com/edwin-luijten/go_command_bus"

)

func main() {

    bus := commandbus.New()

    

    bus.RegisterMiddleware(func(command interface{}, next HandlerFunc) {

        

    	// your logic here

    

        next(command)

    

        // or here

    }, 1) 

}

```
