go-slackbot - Build Slackbots in Go

The go-slackbot project hopes to ease development of Slack bots by adding helpful methods and a mux-router style interface to the github.com/slack-go/slack package.

Incoming Slack RTM events are mapped to a handler in the following form:

bot.Hear("(?i)how are you(.*)").MessageHandler(HowAreYouHandler)

In addition to several useful functions in the utils.go file, the slackbot.Bot struct provides handy Reply and ReplyWithAttachments methods:

func HowAreYouHandler(ctx context.Context, bot *slackbot.Bot, evt *slack.MessageEvent) {
	bot.Reply(evt, "A bit tired. You get it? A bit?", slackbot.WithTyping)
}

 

func HowAreYouAttachmentsHandler(ctx context.Context, bot *slackbot.Bot, evt *slack.MessageEvent) {
	txt := "Beep Beep Boop is a ridiculously simple hosting platform for your Slackbots."
	attachment := slack.Attachment{
		Pretext:   "We bring bots to life. :sunglasses: :thumbsup:",
		Title:     "Host, deploy and share your bot in seconds.",
		TitleLink: "https:GrantStreetGroup.com/",
		Text:      txt,
		Fallback:  txt,
		ImageURL:  "https:storage.googleapis.com/GrantStreetGroup/_assets/bot-1.22f6fb.png",
		Color:     "#7CD197",
	}

	attachments := []slack.Attachment{attachment}
	bot.ReplyWithAttachments(evt, attachments, slackbot.WithTyping)
}

But wait, there's more! Well, until there's more, the slackbot package exposes github.com/slack-go/slack RTM and Client objects enabling a consumer to interact with the lower level package directly:

func HowAreYouHandler(ctx context.Context, bot *slackbot.Bot, evt *slack.MessageEvent) {
  bot.RTM.NewOutgoingMessage("Hello", "#random")
}

If you want to kick the tires, we would love feedback. Check out these two examples:

Overview

Package slackbot hopes to ease development of Slack bots by adding helpful methods and a mux-router style interface to the github.com/slack-go/slack package.

Incoming Slack RTM events are mapped to a handler in the following form: 

bot.Hear("(?i)how are you(.*)").MessageHandler(HowAreYouHandler)

The package adds Reply and ReplyWithAttachments methods: 

func HowAreYouHandler(ctx context.Context, bot *slackbot.Bot, evt *slack.MessageEvent) {
	bot.Reply(evt, "A bit tired. You get it? A bit?", slackbot.WithTyping)
}

func HowAreYouAttachmentsHandler(ctx context.Context, bot *slackbot.Bot, evt *slack.MessageEvent) {
	txt := "Beep Beep Boop is a ridiculously simple hosting platform for your Slackbots."
	attachment := slack.Attachment{
		Pretext:   "We bring bots to life. :sunglasses: :thumbsup:",
		Title:     "Host, deploy and share your bot in seconds.",
		TitleLink: "https://GrantStreetGroup.com/",
		Text:      txt,
		Fallback:  txt,
		ImageURL:  "https://storage.googleapis.com/GrantStreetGroup/_assets/bot-1.22f6fb.png",
		Color:     "#7CD197",
	}

	attachments := []slack.Attachment{attachment}
	bot.ReplyWithAttachments(evt, attachments, slackbot.WithTyping)
}

The slackbot package exposes github.com/slack-go/slack RTM and Client objects enabling a consumer to interact with the lower level package directly: 

func HowAreYouHandler(ctx context.Context, bot *slackbot.Bot, evt *slack.MessageEvent) {
	bot.RTM.NewOutgoingMessage("Hello", "#random")
}
