Start coding your bot: Recast.AI + Slack

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

Requirements

Get your Recast.AI bot token

  • 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!

Get your Slack bot Token

Launch the bot

Complete the config.js file

  • 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,
}

Run

  • install the dependencies
npm install
  • run your bot
npm run start

Go further

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)
  })
})
