/**
This connector required a Slack App to be configured:
  - Go to https://api.slack.com/apps
  - Click on `Create New App`
- Enter a `name` and select a `workspace`
- Click on `Create App`
- Click on your new app
- The signing secret is under `Basic Information` > `App Credentials`
- The token is under `Settings` > `Install App` > OAuth Access Token
*/

const main = async () => {
  // Create a new Slack Connector: Token and signingSecret are found at https://api.slack.com/apps/<your_slack_app_id>/event-subscriptions
  const slackConnector = new SlackConnector(app, {
    token: '<your_slack_token_starting_with_xox>',
    signingSecret: '<your_slack_signing_secret>',
    port: '<slack_receiver_port>', // Default to 3000
    endpoints: '<slack_receiver_endpoints>', // Default to '/'
  })

  /** How to setup events in Slack:
   1 - Go to https://api.slack.com/apps/<your_slack_app_id>/event-subscriptions
   2 - Change request URL to <your_runtime_url>:<slack_receiver_port>/<slack_receiver_endpoints>
   3 - Subscribe to bot events. For example 'message.channels' for notifying Reshuffle when a new message was posted to a channel
   4 - In Reshuffle, use the correct SlackEvents (e.g. SlackEvents.MESSAGE in example below)
