Example

package main

import (
	"go.thethings.network/lorawan-stack/v3/pkg/events"
	"go.thethings.network/lorawan-stack/v3/pkg/events/redis"

	ttnredis "go.thethings.network/lorawan-stack/v3/pkg/redis"
)

func main() {
	// This sends all events received from Redis to the default pubsub.
	redisPubSub := redis.WrapPubSub(events.DefaultPubSub(), ttnredis.Config{
		// Config here...
	})
	// Replace the default pubsub so that we will now publish to Redis.
	events.SetDefaultPubSub(redisPubSub)
}
