events

Crazy Fast Event Dispatcher for golang.

1. NO REFLECTION
2. Async
3. Error Handler
4. Additional Event Store

Events are somethings that happened in the past, are executed async, and you should call it with past name and do not rely on what the listener returns...

Usage example:

helloListener := func(a interface{}) error {
    fmt.Print("Hello ", in)
    return nil
}
errorListener := func(e ListenerError){
    wasError = true
}
 
e := events.New()
e.On("hailed", helloListener)
e.OnError(errorListener) // If one listeners return error != nil

e.Raise("hailed", "World")

e.Wait() // optional

see readme_test.go

Event repository with assertion on events (optional)

Is so useful in our tests to add an event store in order to make assertion on what happened in your system

e := events.New()
e.AddInMemoryEventRepo() // or if you have one inject it see: AddEventRepo

e.On("hailed", helloListener)
e.Contains("hailed")     // true

Test it

install deps go get ./...

and go test ./... -v
