Socket.io Emitter

Library supporting send message from non-socket.io process via redis. (Mostly configured by socket.io and socket.io-redis in NodeJs)

Example

go get -u github.com/ginkcode/socket.io-emitter

import "github.com/ginkcode/socket.io-emitter"
import "github.com/go-redis/redis/v7"

func Test() {
    opts := &redis.Options{Addr: "localhost:6379"}
    rdWrapper, err := NewWrapperWithOptions(opts)
    if err != nil {
        panic("Can't create Redis wrapper")
    }
    emitter := NewEmitter("prefix", "/namespace", rdWrapper)
    if err := emitter.To("chat").Emit("Hello world"); err != nil {
        panic("Can't send message to chat room")
    }
    
    if err := emitter.Broadcast("Hello World"); err != nil {
        panic("Can't broadcast message")
    }
}

Notes

• emitter use its own Rooms to combine and pack the message before emitting and then reset it. Let's create new instance or check mutex lock to avoid race condition.
• Can reuse redis connection by passing redis.Client or redis.ClusterClient by NewWrapper() or NewWrapperWithCluster()
