DnD Discord Bot

Discord helper bot to help with future DnD sessions on Discord

TODO

1. Make commands for most commonly used dice rolls (i.e checks, saving throws, attack rolls, etc)
2. Refactor duplicate code
3. Work on processing multiple, comma-separated dice expressions (i.e 3d8+2, 1d20+1, etc.)
4. Create an auto-updating GitHub wiki page for all slash commands using a GitHub action and Discord API

Setup

1. Install Devbox
2. Setup your Discord application
3. Setup environment variables in a .env file

DISCORD_APPLICATION_ID=""
DISCORD_PUBLIC_KEY=""
DISCORD_TOKEN=""

4. Create an account at ngrok, which will be used to expose the local development server to Discord
5. Use deno task ngrok and deno task start in two separate terminals; one will be for ngrok and another for the server respectively
6. Use the URL given in the ngrok terminal under Forwarding that points to localhost as the Interactions Endpoint URL in your Discord application (change the URL with your production URL when switching to production)
7. Invite the bot to your server at the /invite endpoint and you're done :)
