bot

Discord bot made for Undertale/Deltarune Wiki's Discord server. It is meant to run through Cloudflare Workers.

Configuration

The bot can be configured for local development using either a .dev.vars file (for development) or a .env file (for production). The production file is only used when running maintenance scripts. The available configuration variables are:

• APP_ID: Discord application's ID
• BOT_TOKEN: Discord bot token
• BOT_PUBLIC_KEY: Discord application's public key (for command verification)
• VERIFY_GUILD: ID of the server used for wiki account verification
• VERIFY_ROLE: ID of the role given to users who verify their wiki account
• VERIFY_WEBHOOK: Webhook URL of the webhook which posts whenever a user successfully verifies their wiki account
• VERIFY_CHANNEL: ID of the channel where the bot should post a message with the verification button
• VERIFY_MESSAGE: ID of the message which the bot should edit instead of posting anew
• OAUTH_CLIENT_ID: Client ID of the OAuth application on the wiki used for account verification
• OAUTH_CLIENT_SECRET: Client secret of the OAuth application on the wiki used for account verification
• SECRET_KEY: Randomly generated string used for generating verification state
• WIKI_REST_API: URL to the rest.php endpoint of the target wiki for verification
• ZEPTOMAIL_AUTH: Secret received from Zeptomail to verify their webhook requests
• NOTIFICATION_CHANNEL: Channel ID of the channel where Zeptomail bounces should be sent

Maintenance scripts

These scripts can be run through npm run:

• npm start: Starts a development server at localhost:8787
  • You might want to install ngrok and run ngrok http 8787 to obtain a public IP, then set your public URL as the interaction endpoint in your Discord application
• npm run deploy: Deploys the current code to Cloudflare Workers (production)
• npm run cf-typegen: Regenerates types in worker-configuration.d.ts
• npm run register[-prod]: Registers Discord bot commands so they can be used
• npm run post[-prod]: Posts a message with a verification button

Scripts with a -prod suffix use the .env file for their configuration, whereas the others use the .dev.vars file.
