A slack bot that proxies messages out to OpenAI's ChatGPT API.
A Dockerfile is provided to bundle up the application, if Heroku is not an option for you.
To easily create the Slack app, use slack-manifest-template.yaml in the "create new apps" page on Slack. Make sure to update the event subscription URL once the gpt-slack application is deployed.

SLACK_BOT_TOKEN: Obtain this (and the other slack variables) from the Slack Bolt JS getting started guide.SLACK_SIGNING_SECRETSLACK_APP_TOKEN: If an app token is provided, the application will run in "socket mode," and will not need to have an incoming request URL configured. Only set this value if you intend to run in socket mode. Attempting to do a webhook event subscription with this value set may fail.OPENAI_API_KEY: Obtain this from OpenAI
