This Starter-Kit will help you start coding a bot connected to Slack with Recast.AI.

• Create an account on Recast.AI
• Create an account on Slack

• Log in to your Recast.AI account
• Create your Bot
• Create intents and fill them with some expressions
• Build your conversation flow on bot builder in the 'Build' tab
• In the tab menu, click on the the little screw
• Here is the request access token you will need to configure your bot!

• Go to https://YOUR_ORGANISATION.slack.com/services/new/bot (replace it with the name of your team)
• Create a new bot and follow the procedure
• That's it, you can now get the code located in the API Token field!

• Clone this Repository

git clone https://github.com/RecastAI/bot-slack.git

• Fill the config.js with your tokens

const config =
{
	recast: {
		token: 'RECAST TOKEN',
		language: 'en',
	},
	slack: {
		token: 'SLACK TOKEN',
	},
	port: 8080,
}

• install the dependencies

npm install

• run your bot

npm run start

Here is the heart of your bot. The following function is called every time your bot receives a message. 'res' is full of precious information:

• use res.memory('notion') to access a notion you just got in the input like a email address, a datetime etc...
• use res.action to get the current action according to your bot builder flow
• in action, you can find a done boolean to know if this action is complete according to the requirements (ex: booking need to signin, signin needs a login)
• use res.reply() to get the reply you've set for this action
• use res.replies to get an array containing the reply set for the action && the following one if the next action is complete
• use res.nextActions to get an array of all the following actions

For more information, please read the SDK NodeJS documentation

rtm.on(slackEvent.MESSAGE, (message) => {
  const user = rtm.dataStore.getUserById(message.user)
  const dm = rtm.dataStore.getDMByName(user.name).id

	// CALL TO RECAST.AI: message.user contains a unique ID of your conversation in Slack
  // The conversationToken is what lets Recast.AI identify your conversation.
  // As message.user is what identifies your Slack conversation, you can use it as conversationToken.

  recastClient.textConverse(message.text, { conversationToken: message.user })
  .then((res) => {
    const replies = res.replies
    const action = res.action

    if (!replies.length) {
      rtm.sendMessage('I didn\'t understand... Sorry :(', dm)
      return
    }

    if (action && action.done) {
      // Use external services: use res.memory('notion') if you got a notion from this action
    }

    replies.forEach(reply => rtm.sendMessage(reply, dm))
  })
  .catch(() => {
    rtm.sendMessage("I'm getting tired, let's talk later", dm)
  })
})
