# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Scope
This is the **settings-site** subdirectory of the broccolini-bot repo. It is a **separate Express process** that provides an admin web UI for editing the bot's runtime config. It is **not** part of the bot's Node process.
The parent repo's rules in `/opt/broccolini-bot/CLAUDE.md` still apply here — especially **CommonJS only**, **read before write**, and **no unsolicited refactors**. Read that file alongside this one.
## Commands
- `npm start` — run the settings site (`node server.js`).
- `npm run dev` — run with `node --watch` for auto-reload.
- No lint, no test framework, no build step. Frontend is vanilla JS served from `public/` — no bundler.
- Deploy via its own compose file: `docker compose up --build -d` from this directory. Container name `broccolini-settings`, joins external `broccoli-net`.
## Architecture
### Two processes, one `.env`
The settings site is a thin HTTPS-oriented proxy in front of the bot's internal API:
```
browser ──► settings server.js (:SETTINGS_PORT, default 12752)
│ session auth (SETTINGS_ADMIN_PASSWORD)
bot internalApp (127.0.0.1:INTERNAL_API_PORT, default 12753)
│ header auth (x-internal-secret = INTERNAL_API_SECRET)
routes/internalApi.js in /opt/broccolini-bot
```
`server.js` loads `../.env` (the **bot's** env file) — both processes share it. `docker-compose.yml` also mounts `env_file: ../.env`, not a local one. There is no settings-site-specific env beyond what's in `.env.example`.
### Proxied endpoints
`server.js` exposes five authenticated endpoints that forward to the bot's `/internal/*` API via `callBot()`:
| Settings route | Bot route |
|---|---|
| `GET /api/config` | `GET /internal/config` |
| `POST /api/config` | `POST /internal/config` |
| `GET /api/discord/guild` | `GET /internal/discord/guild` |
| `POST /api/restart` | `POST /internal/restart` |
| `GET /api/restart/status` | `GET /internal/restart/status` |
Every response-shape change in the bot's `/internal/*` handlers (`routes/internalApi.js`) is a breaking change here. The bot also gates `POST /internal/config` on an `ALLOWED_CONFIG_KEYS` allowlist — **adding a new field to the UI requires adding the key to that Set in the bot first**, otherwise the save returns 400 for that key.
### Session cookie requires HTTPS
`server.js:20-26` sets `cookie.secure: true`. Browsers will refuse to persist the session cookie over plain HTTP, so login silently fails when not behind an HTTPS reverse proxy (`SETTINGS_DOMAIN` is the deployed domain). If you're reproducing a login bug, check this first before debugging auth logic. The `session secret` falls back to `'fallback-secret-change-me'` when `INTERNAL_API_SECRET` is unset — don't rely on the fallback in any environment that matters.
### Client-side routing
`public/index.html` is a single page with all sections rendered; `public/js/app.js` toggles `.hidden` on sections based on `location.pathname`. Routes live in the `ROUTES` map (`app.js:425`). The server has `app.get('*', requireAuth, …)` as a catch-all back to `index.html` (`server.js:97`), so any new client route works without server changes as long as it's added to `ROUTES`.
### Config field binding (frontend)
Any form element with `data-key="SOME_CONFIG_KEY"` participates in the editor:
- `populateFields()` (`app.js:102`) fills it from `GET /api/config` and wires change listeners.
- Checkboxes serialize to the strings `'true'` / `'false'`, and `<input type="color">` serializes to `0xRRGGBB` — this matches how the bot stores these values.
- `pendingChanges` accumulates diffs; `saveConfig()` POSTs the whole diff at once.
- `data-smart="channel|category|role|member|multi-member"` swaps the bare `<input>` for a searchable Discord picker backed by `GET /api/discord/guild` (see `public/js/discord.js`).
**To add a new editable config field:** (1) add the key to the bot's `ALLOWED_CONFIG_KEYS`, (2) add a `<input data-key="NEW_KEY">` (optionally `data-smart=…`) inside the appropriate `.section` in `public/index.html`. No JS changes needed.
### Notification thresholds editor
The Notifications section is **not** a simple `data-key` field — it's a custom editor (`app.js:239-423`) that serializes into a single hidden `NOTIFICATION_THRESHOLDS_JSON` field. Alert keys are hard-coded in `NOTIFICATION_TAB_KEYS` (surge / patterns / unclaimed / chat) and described in `NOTIFICATION_ALERT_DESCRIPTIONS`. **Adding a new alert key requires editing both of those objects** — otherwise it won't show up in any tab. Threshold values accept whole numbers or duration strings matching `^(\d+[mhd])+$` (e.g. `15m`, `1h`, `1d6h`).
## Gotchas
- The frontend has no framework and no build — edit `public/js/*.js` directly; changes are live on reload.
- `getaddrinfo` failures from `callBot()` surface to the UI as "Bot unreachable" (502). This is almost always the bot process being down or the internal port being wrong, not a bug in this codebase.
- `docker-compose.yml` binds the port to the Tailscale IP `100.114.205.53:12752` — not `0.0.0.0`. Changing that binding has security implications.
