gundyr

Gundyr provides an easy to use interface to the Helix Twitch API and Twitch PubSub.

It handles both app access as well as user access tokens. All tokens used are automatically refreshed.

This is a work in progress and not all Helix or PubSub endpoints are supported yet.

Usage

Helix - Getting a User ID

cfg := &gundyr.HelixConfig{
	ClientID:     clientID, 
	ClientSecret: clientSecret,
}

c, err := gundyr.NewHelix(cfg)
if err != nil {
	log.Fatal(err)
}

userID, err := c.UserToID("kyrotobi")
if err != nil {
	log.Fatal(err)
}
log.Println(userID)

Helix - Using User Access Tokens

If an OAuth2 token is not provided to HelixConfig, authentication will attempt to use the OAuth2 Client Credentials flow to obtain a App Access token.

// See examples/auth_token.go on creating/retrieving tokens.
cfg := &gundyr.HelixConfig{
	ClientID:     clientID,
	ClientSecret: clientSecret,
	Scopes:       []string{"user:read:email"},
	RedirectURI:  redirectURI,
	Token:        token,
}

c, err := gundyr.NewHelix(cfg)
if err != nil {
	log.Fatal(err)
}

email, err := c.GetUserEmail("your-username")
if err != nil {
	log.Fatal(err)
}
log.Println(email)

PubSub - Subscribing to Channel Point Redemptions

func handleChannelPoints(event *pubsub.ChannelPointsEvent) {
	fmt.Println(event.Redemption.Reward.Title)
}

func main() {
	scopes := []string{"channel:read:redemptions"}

	// Setup OAuth2 configuration
	config, err := auth.NewUserAuth(clientID, clientSecret, redirectURI, &scopes)
	if err != nil {
		log.Fatal(err)
	}

	// See examples/auth_token.go for an example on creating a new token.
	token, err := auth.RetrieveTokenFile(config, tokenFile)
	if err != nil {
		log.Fatal(err)
	}

	// Create a PubSub client and listen to the topics.
	client := pubsub.NewClient(userID, token)
	client.ListenChannelPoints(handleChannelPoints)
	client.Connect()
	select {}
}
