Getting Started

Wrangler

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
