Getting Started

You'll need to setup a new Slack App and add a Bot User, as well as enable Event Subscriptions. Pick any username for your Bot User, and for your Event Subscrition, use the following details:

• Request URL: https://<your-domain>/slack/event
• Add the following Bot Events
  • message.channels
  • message.groups
  • message.im
  • message.mpim

A Firebase project is also required. Slack Team data from the "Add to Slack" OAuth flow, as well as conversation state is stored there. Make sure to add your service account key file as firebase.json and set your FIREBASE_DB_URL environment variable.

Running App

Once you have your app running, if you visit the root, https://<your-domain>/ it will render a page with an "Add to Slack" button you can use to add it to one of your Slack teams and start sending it messages.

Try asking the bot for help in a direct message
