Split the original 309-line poll() into single-responsibility helpers and a thin orchestrator. No behavior change — every Gmail API call, Discord call, DB write, and log line stays in the same order with the same arguments. Helpers extracted (module-private): - locateGuild(client) — DISCORD_GUILD_ID lookup with fallback warning. - parseGmailMessage(email) — header parsing, body decode, dual cleanup (firstBody for new-ticket message, followupBody for thread append). - findOrCreateTicketChannel(guild, parsed, number) — category resolution + channel.create with the existing two-stage error handling. - linkPreviousTranscripts(ticketChan, threadId, client) — best-effort prior-transcript link on reopen. - markGmailMessageRead(gmail, msgRef) — wraps the batchModify call used in five places across the original. - oauthSuspendIfPermanent(err, client) — invalid_grant/invalid_client classify, suspend polling, clear interval, DM admin once. Returns bool. poll() is now the orchestrator: list → locate guild → for each message, parse → look up existing ticket → branch (append-followup vs new-ticket flow) → mark read. The new-ticket branch stays inline in poll() per the "keep poll() as orchestration" intent.
Broccolini Bot
A Node.js Discord bot that bridges Gmail ↔ Discord for support ticketing, with MongoDB for state. Built for Indifferent Broccoli (game-server hosting).
- Inbound email → Discord ticket channel.
- Staff messages in that channel → Gmail reply (threaded).
- Discord-originated tickets (panel / context menu) live entirely in Discord.
For an architectural overview, see HOWITWORKS.md. For agent/contributor conventions, see CLAUDE.md.
Quick start
git clone <repo-url>
cd broccolini-bot
npm install
cp .env.example .env
# fill DISCORD_TOKEN, DISCORD_APPLICATION_ID, DISCORD_GUILD_ID, TICKET_CATEGORY_ID,
# ROLE_ID_TO_PING, MONGODB_URI, GOOGLE_CLIENT_ID/SECRET, REFRESH_TOKEN, MY_EMAIL
npm start
Need a Gmail refresh token? node get-refresh-token.js (redirect URI http://localhost:3000/oauth2callback). Probe Mongo with npm run test-mongodb.
Restart the bot after any .env change. Restart also re-registers slash commands.
Deploy (Docker)
docker compose up --build -d
docker logs broccolini --tail 50 -f
Host port 8892 → container 5000 (DISCORD_ONLY_PORT).
Configuration
All config is environment variables loaded by config.js into CONFIG. The full list — with descriptions and defaults — lives in .env.example. Highlights:
| Variable | Notes |
|---|---|
DISCORD_TOKEN / DISCORD_BOT_TOKEN |
Bot token. First non-empty after trim wins. |
DISCORD_APPLICATION_ID, DISCORD_GUILD_ID |
Required for slash command registration. |
TICKET_CATEGORY_ID |
Default category for email tickets. Validated at startup. |
DISCORD_TICKET_CATEGORY_ID |
Category for Discord panel/context tickets (falls back to TICKET_CATEGORY_ID). |
ROLE_ID_TO_PING |
Support role pinged on new tickets. |
MONGODB_URI |
Mongo connection string. |
GOOGLE_CLIENT_ID / GOOGLE_CLIENT_SECRET / REFRESH_TOKEN / MY_EMAIL |
Gmail OAuth + canonical inbox address. |
RENAMER_BOT |
Optional secondary token used for channel renames. |
INTERNAL_API_SECRET / INTERNAL_API_PORT |
Enable the internal config API used by the settings UI. |
Slash commands
| Command | Purpose |
|---|---|
/escalate, /deescalate |
Move ticket between tier 2/3 categories. |
/add, /remove |
Add/remove user from current ticket channel. |
/transfer |
Hand the claim to another staff member. |
/move |
Reparent the channel to another category. |
/force-close, /cancel-close, /closetimer |

Settings UI (optional)
settings-site/ is a separate Express app that talks to the bot's internal config API over the broccoli-net Docker network using INTERNAL_API_SECRET. It is not part of this bot's process. See settings-site/CLAUDE.md.
Troubleshooting
| Symptom | Check |
|---|---|
| Slash commands missing | Correct DISCORD_APPLICATION_ID + DISCORD_GUILD_ID; restart; Discord can take a minute to sync. |
| Gmail not ingesting | REFRESH_TOKEN valid? Auth failure halts polling — re-auth and restart. |
| Mongo errors at startup | MONGODB_URI reachable? npm run test-mongodb to confirm. |
| Channel rename "too quickly" | Discord limit is 2 renames/10 min per channel — the queue serializes; wait it out. |
| Modal/button no response | Bot online + intents enabled; check DEBUGGING_CHANNEL_ID / container logs. |
