Connect to redis with golang on heroku

golang_redis.go

import 	"gopkg.in/redis.v3"

var (
	//Client for the database connection
	client *redis.Client
)

func connect() {
	var resolvedURL = os.Getenv("REDIS_URL")
	var password = ""
	if !strings.Contains(herokuURL, "localhost") {
		parsedURL, _ := url.Parse(herokuURL)
		password, _ = parsedURL.User.Password()
		resolvedURL = parsedURL.Host
	}
	fmt.Printf("connecting to %s", herokuURL)
	client = redis.NewClient(&redis.Options{
		Addr:     resolvedURL,
		Password: password,
		DB:       0, // use default DB
	})
}

Hey! I just found this, thanks for sharing it -- very helpful. I do see that herokuURL is undefined. It looks like putting a var herokuURL = "" (e.g. after line 10) or just replacing herokuURL with resolvedURL would work

Yup, that was helpful! You're also missing the net/url import :)

welp thanks for posting this, just saved me some a considerable number of hours 👯
