Serverless Discord bot in webhook mode to quickly interface with OpenAI's Chat Completion API

Note: This is mainly for personal use, if you would like to add features, do fork the repository. Do perform PRs back if you would be so kind!

• A Cloudflare account with Workers (at least free-tier) enabled
• Completed the Discord Developers - Getting Started - Creating an App with the same scopes and have added the bot to your target server
• An OpenAI API key that has the ability to use the Chat Completion API

1. Clone this repository
2. Run npm ci or yarn install
3. Replace {DISCORD_TOKEN} and {DISCORD_APPLICATION_ID} in the following DISCORD_TOKEN={DISCORD_TOKEN} DISCORD_APPLICATION_ID={DISCORD_APPLICATION_ID} npx node src/register.js and run it to register the bot commands
4. Run npx wrangler secret put DISCORD_APPLICATION_ID and set the Discord app's ID
5. Run npx wrangler secret put DISCORD_PUBLIC_KEY and set the Discord app's public key
6. Run npx wrangler secret put DISCORD_TOKEN and set the Discord bot's token
7. Run npx wrangler secret put OPENAI_API_KEY and set the OpenAI API key
8. Add space-delimited user IDs to whitelist in DISCORD_USERID_WHITELIST in wrangler.toml
9. (Optional) To allow extra lines of context, run npx wrangler kv:namespace create context and replace the ID of CHATGPT_DISCORD_BOT_KV and increase CONTEXT to more than 0 in wrangler.toml (will consume a lot more tokens), else remove kv_namespaces block entirely from wrangler.toml
10. (Optional) To change the model, update CHATGPT_MODEL in wrangler.toml to whatever you want as documented at https://platform.openai.com/docs/api-reference/chat/create#chat/create-model
