simple pubsub for golang.

go-pubsub

Simple publish subscribe queue. This is available only inside application. There is no intent to make this span across processes/machines.

Examples

ps := pubsub.New()
subscriber := ps.Subscribe("user:1", "user:2").Do(func(message Message) {
    println("We got meessage on topic", message.Topic())
})

defer subscriber.Close()

count := ps.Publish(NewMessage("user:1:username", "hello"))

fmt.Printf("Published messages to %v subscribers", count)

go-pubsub has also default Hub, if you don't need to track your own Hub.

subscriber := pubsub.Subscribe("user:1", "user:2").Do(func(message Message) {
    println("We got meessage on topic", message.Topic())
})

defer subscriber.Close()

count := pubsub.Publish(NewMessage("user:1:username", "hello"))

fmt.Printf("Published messages to %v subscribers", count)
