Dependencies

Install

go get github.com/shomali11/slacker

Preparing your Slack App

To use Slacker you'll need to create a Slack App, either manually or with an app manifest. The app manifest feature is easier, but is a beta feature from Slack and thus may break/change without much notice.

Manual Steps

Slacker works by communicating with the Slack Events API using the Socket Mode connection protocol.

To get started, you must have or create a Slack App and enable Socket Mode, which will generate your app token (SLACK_APP_TOKEN in the examples) that will be needed to authenticate.

Additionally, you need to subscribe to events for your bot to respond to under the Event Subscriptions section. Common event subscriptions for bots include app_mention or message.im.

After setting up your subscriptions, add scopes necessary to your bot in the OAuth & Permissions. The following scopes are recommended for getting started, though you may need to add/remove scopes depending on your bots purpose:

  • app_mentions:read
  • channels:history
  • chat:write
  • groups:history
  • im:history
  • mpim:history

Once you've selected your scopes install your app to the workspace and navigate back to the OAuth & Permissions section. Here you can retrieve yor bot's OAuth token (SLACK_BOT_TOKEN in the examples) from the top of the page.

With both tokens in hand, you can now proceed with the examples below.

App Manifest

Slack App Manifests make it easy to share a app configurations. We provide a simple manifest that should work with all the examples provided below.

The manifest provided will send all messages in channels your bot is in to the bot (including DMs) and not just ones that actually mention them in the message.

If you wish to only have your bot respond to messages they are directly messaged in, you will need to add the app_mentions:read scope, and remove:

  • im:history # single-person dm
  • mpim:history # multi-person dm
  • channels:history # public channels
  • groups:history # private channels

You'll also need to adjust the event subscriptions, adding app_mention and removing:

  • message.channels
  • message.groups
  • message.im
  • message.mpim

Examples

Example 1

Defining a command using slacker

package main

import (
	"context"
	"log"
	"os"

	"github.com/shomali11/slacker"
)

func main() {
	bot := slacker.NewClient(os.Getenv("SLACK_BOT_TOKEN"), os.Getenv("SLACK_APP_TOKEN"))

	definition := &slacker.CommandDefinition{
		Handler: func(botCtx slacker.BotContext, request slacker.Request, response slacker.ResponseWriter) {
			response.Reply("pong")
		},
	}

	bot.Command("ping", definition)

	ctx, cancel := context.WithCancel(context.Background())
	defer cancel()

	err := bot.Listen(ctx)
	if err != nil {
		log.Fatal(err)
	}
}

Example 2

Defining a command with an optional description and example. The handler replies to a thread.

package main

import (
	"context"
	"log"
	"os"

	"github.com/shomali11/slacker"
)

func main() {
	bot := slacker.NewClient(os.Getenv("SLACK_BOT_TOKEN"), os.Getenv("SLACK_APP_TOKEN"))

	definition := &slacker.CommandDefinition{
		Description: "Ping!",
		Examples:    []string{"ping"},
		Handler: func(botCtx slacker.BotContext, request slacker.Request, response slacker.ResponseWriter) {
			response.Reply("pong", slacker.WithThreadReply(true))
		},
	}

	bot.Command("ping", definition)

	ctx, cancel := context.WithCancel(context.Background())
	defer cancel()

	err := bot.Listen(ctx)
	if err != nil {
		log.Fatal(err)
	}
}

Example 3

Defining a command with a parameter. Parameters surrounded with {} will be satisfied with a word. Parameters surrounded with <> are "greedy" and will take as much input as fed.

package main

import (
	"context"
	"log"
	"os"

	"github.com/shomali11/slacker"
)

func main() {
	bot := slacker.NewClient(os.Getenv("SLACK_BOT_TOKEN"), os.Getenv("SLACK_APP_TOKEN"))

	bot.Command("echo {word}", &slacker.CommandDefinition{
		Description: "Echo a word!",
		Examples:    []string{"echo hello"},
		Handler: func(botCtx slacker.BotContext, request slacker.Request, response slacker.ResponseWriter) {
			word := request.Param("word")
			response.Reply(word)
		},
	})

	bot.Command("say <sentence>", &slacker.CommandDefinition{
		Description: "Say a sentence!",
		Examples:    []string{"say hello there everyone!"},
		Handler: func(botCtx slacker.BotContext, request slacker.Request, response slacker.ResponseWriter) {
			sentence := request.Param("sentence")
			response.Reply(sentence)
		},
	})

	ctx, cancel := context.WithCancel(context.Background())
	defer cancel()

	err := bot.Listen(ctx)
	if err != nil {
		log.Fatal(err)
	}
}

Example 4

Defining a command with two parameters. Parsing one as a string and the other as an integer. (The second parameter is the default value in case no parameter was passed or could not parse the value)

package main

import (
	"context"
	"log"
	"os"

	"github.com/shomali11/slacker"
)

func main() {
	bot := slacker.NewClient(os.Getenv("SLACK_BOT_TOKEN"), os.Getenv("SLACK_APP_TOKEN"))

	definition := &slacker.CommandDefinition{
		Description: "Repeat a word a number of times!",
		Examples:    []string{"repeat hello 10"},
		Handler: func(botCtx slacker.BotContext, request slacker.Request, response slacker.ResponseWriter) {
			word := request.StringParam("word", "Hello!")
			number := request.IntegerParam("number", 1)
			for i := 0; i < number; i++ {
				response.Reply(word)
			}
		},
	}

	bot.Command("repeat {word} {number}", definition)

	ctx, cancel := context.WithCancel(context.Background())
	defer cancel()

	err := bot.Listen(ctx)
	if err != nil {
		log.Fatal(err)
	}
}

Example 5

Defines two commands that display sending errors to the Slack channel. One that replies as a new message. The other replies to the thread.

package main

import (
	"context"
	"errors"
	"log"
	"os"

	"github.com/shomali11/slacker"
)

func main() {
	bot := slacker.NewClient(os.Getenv("SLACK_BOT_TOKEN"), os.Getenv("SLACK_APP_TOKEN"))

	messageReplyDefinition := &slacker.CommandDefinition{
		Description: "Tests errors in new messages",
		Handler: func(botCtx slacker.BotContext, request slacker.Request, response slacker.ResponseWriter) {
			response.ReportError(errors.New("Oops!"))
		},
	}

	threadReplyDefinition := &slacker.CommandDefinition{
		Description: "Tests errors in threads",
		Handler: func(botCtx slacker.BotContext, request slacker.Request, response slacker.ResponseWriter) {
			response.ReportError(errors.New("Oops!"), slacker.WithThreadError(true))
		},
	}

	bot.Command("message", messageReplyDefinition)
	bot.Command("thread", threadReplyDefinition)

	ctx, cancel := context.WithCancel(context.Background())
	defer cancel()

	err := bot.Listen(ctx)
	if err != nil {
		log.Fatal(err)
	}
}

	definition := &slacker.CommandDefinition{
		Description: "Upload a sentence!",
		Handler: func(botCtx slacker.BotContext, request slacker.Request, response slacker.ResponseWriter) {
			sentence := request.Param("sentence")
			client := botCtx.Client()
			ev := botCtx.Event()

			if ev.Channel != "" {
				client.PostMessage(ev.Channel, slack.MsgOptionText("Uploading file ...", false))
				_, err := client.UploadFile(slack.FileUploadParameters{Content: sentence, Channels: []string{ev.Channel}})
				if err != nil {
					fmt.Printf("Error encountered when uploading file: %+v\n", err)
				}
			}
		},
	}

	bot.Command("upload <sentence>", definition)

Troubleshooting

My bot is not responding to events

There are a few common issues that can cause this:

  • The OAuth (bot) Token may be incorrect. In this case authentication does not fail like it does if the App Token is incorrect, and the bot will simply have no scopes and be unable to respond.
  • Required scopes are missing from the OAuth (bot) Token. Similar to the incorrect OAuth Token, without the necessary scopes, the bot cannot respond.
  • The bot does not have the correct event subscriptions setup, and is not receiving events to respond to.
