Claude 986a8d5d86 News post → town crier + Discord announcement pipeline
Replace the fire-and-forget Discord-only announce on publish with a
retry-safe, two-leg pipeline. When a post transitions into published-news
(false→true publish while in news, or category→news while published), an
announce_jobs row is enqueued with two INDEPENDENT delivery legs:

  • town crier — sidecar POST /towncrier via uoLinkClient (stable id
    `post-<id>` so a retry replaces rather than duplicates)
  • discord    — bot POST /internal/announce via botInternalClient
    (single source of truth for the #news channel stays in the bot)

An in-process poller (utils/announceWorker) sweeps the table every
ANNOUNCE_POLL_MS and dispatches each due leg with its own exponential
backoff (30s→2h, 6 attempts). A leg is retried on transient failures
(503/504/network) and failed fast on data/config errors (400 over-cap,
401/409). Publishing never blocks on the sidecar or Discord — enqueue is
local DB only. Parent `status` is a done/partial/failed rollup of the two
legs; posts.announced_at is stamped once both deliver.

Admin visibility: GET /admin/posts/:id/announce + a per-leg Retry
(POST .../announce/retry) surfaced in the PostEditor for news posts.

Pure decisions (text build/caps, classification, backoff, rollup) live in
announceJobs.logic and are unit-tested (server/test/announceJobs.test.js,
10 tests). The old manual /admin/uo-link/towncrier form is untouched.

# UOMysticmoon Website
Public site, wiki, and protected admin panel for the **UOMysticmoon** private Ultima Online
shard — a full-stack app in one repo:
- **Backend** — Node.js + Express REST API (layered `router → controller → model → db`), MariaDB, a provider-agnostic session layer (JWT cookie for web, bearer tokens for mobile, pluggable SSO).
- **Frontend** — React + Vite single-page app (public site, wiki, and the admin panel), dark "gothic" theme (Cinzel + Georgia).
- **Deploy** — Docker Compose (app + MariaDB) behind a Pangolin reverse proxy. Express serves the built SPA in production.
- **Shard link** — a live bridge to the in-game ServUO shard through the **uo-link** sidecar ([UOM/link](https://gitea.whitlocktech.com/UOM/link)): the site ingests a live event feed and makes server-side REST calls to show shard status, economy, staff presence, IDOCs, live activity, and per-character sheets. See [Shard integration (uo-link)](#shard-integration-uo-link).
The design reference is [BACKEND_DESIGN.md](BACKEND_DESIGN.md) (API contract, schema, security).

---
## Prerequisites
- **Node.js 20+** and npm (Node 22/24 are fine).
- **Docker Desktop** (for MariaDB, and for the full Compose deploy).
---
## Setup & run
### Option A — Docker Compose (full stack)
The simplest way to run everything. The image installs server deps, **builds the React client**,
and Express serves it; MariaDB runs in its own container; tables + defaults + the first admin are
created automatically on first boot.
```bash
cp .env.example .env
# Edit .env and set at least:
# DB_PASSWORD, DB_ROOT_PASSWORD (any strong values)
# JWT_SECRET (a long random string)
# ADMIN_USERNAME, ADMIN_PASSWORD (your first admin login)
docker compose up -d --build
```
- App: **http://localhost:3000** (binds `0.0.0.0`)
- Health check: `GET http://localhost:3000/api/health``{ "status": "ok" }`
- Logs: `docker compose logs -f app` (and `./logs/app.log` on the host)
- Stop: `docker compose down` (add `-v` to also wipe the database + uploads volumes)
### Option B — Local development (hot reload)
Run the API and the Vite dev server separately. The Vite server proxies `/api` and `/uploads`
to the backend, so the SPA stays same-origin (cookies work).
**1. Start a MariaDB the backend can reach** (published on `localhost:3306`):
```bash
docker run -d --name uomm-db -p 3306:3306 -e MARIADB_DATABASE=uomysticmoon -e MARIADB_USER=uomm -e MARIADB_PASSWORD=devpass -e MARIADB_ROOT_PASSWORD=rootpass mariadb:11
```
**2. Configure + start the backend** (terminal 1):
```bash
cp server/.env.example server/.env
# Set DB_HOST=127.0.0.1, DB_PORT=3306, DB_USER=uomm, DB_PASSWORD=devpass,
# JWT_SECRET=<anything>, ADMIN_USERNAME=admin, ADMIN_PASSWORD=<your password>
npm run install-server
npm run server # nodemon → http://localhost:3000
```
**3. Start the frontend** (terminal 2):
```bash
npm run install-client
npm run client # Vite → http://localhost:5173
```
Develop at **http://localhost:5173** (hot reload). On Windows, the Vite proxy targets
`127.0.0.1:3000` to avoid the IPv6-`localhost` pitfall.
> Tip: `npm run install-all` installs both server and client deps in one go.
### Option C — Production build without Docker
Build the SPA and let Express serve it on a single port (still needs a MariaDB + `server/.env`):
```bash
npm run install-all
npm run build # → client/dist
npm start # node server → serves API + SPA at http://localhost:3000
```
---
## First admin & site mode
- On first boot, if the `users` table is empty and `ADMIN_USERNAME` / `ADMIN_PASSWORD` are set,
the first admin is created automatically. You can also run `npm run seed`. After it exists you
may blank those env vars.
- The site **starts in `maintenance` mode**: public visitors see the polished "coming soon" page;
the admin login and panel are always reachable.
- Sign in at **`/admin/login`**, then flip **Maintenance → Live** from the Dashboard. A logged-in
admin can preview the live site even while it's in maintenance.
---
## Pages & routes
**Public** (gated by site mode):
| Route | Page |
|---|---|
| `/` | Portal landing (hero + destinations) |
| `/site` | Website index (section cards) |
| `/site/news` | News feed |
| `/site/screenshots` | Screenshot gallery |
| `/site/five-on-friday` | Five on Friday |
| `/site/newsletter` · `/site/newsletter/:id` | Newsletter list + issue |
| `/site/about` · `/site/status` | About · Shard status |
| `/wiki` · `/wiki/:slug` | Wiki landing + article (auto table-of-contents) |
**Admin** (cookie auth, `noindex`):
| Route | View |
|---|---|
| `/admin/login` | Sign in |
| `/admin` | Dashboard (mode toggle, stats, recent activity) |
| `/admin/posts` | Posts CRUD + publish + image upload |
| `/admin/wiki` | Wiki pages CRUD |
| `/admin/settings` | Site settings |
| `/admin/activity` | Activity log |
| `/admin/bot-activity` | Bot activity — banned IPs + recent scoring events, emergency unban (admin only) |
| `/admin/auth-providers` | Authentication — enable/configure SSO providers: built-in Google & Discord + custom OIDC/OAuth2 (admin only) |
| `/admin/users` | User management |
| `/admin/account` | Account security (self-service TOTP two-factor + linked SSO accounts) |
---
## API endpoints
| Group | Base | Auth |
|---|---|---|
| Auth (web) | `/api/v1/auth` (`login`, `login/totp`, `logout`, `me`) | cookie |
| Auth (mobile) | `/api/v1/auth/mobile` (`login`, `refresh`, `logout`) | bearer (access + refresh tokens) |
| SSO | `/api/v1/auth` (`providers` — public discovery; `sso/:provider/start`, `sso/:provider/link`, `sso/:provider/callback`) | redirect flow |
| Public | `/api/v1/public` (`settings`, `status`, `posts/:category`, `posts/:category/:idOrSlug`, `wiki`, `wiki/:slug`, `contact`) | none |
| Admin | `/api/v1/admin` (`dashboard`, `site-mode`, `posts`, `posts/upload`, `wiki`, `settings`, `activity`, `bot-activity`, `bot-activity/unban`, `auth/providers` (CRUD), `users`, `account`, `account/totp/*`, `account/identities`) | cookie (admin) |
| Public · Shard | `/api/v1/public/shard` (`status`, `feed`, `economy`, `online`, `idoc`, `stream`) | none |
| Player · Shard | `/api/v1/player/shard` (`link`, `accounts`, `roster/:account`, `vendors/:account`, `char/:serial`, `sales`) | cookie/bearer (player) |
| Admin · Shard | `/api/v1/admin/shard` (self linking, same as player) · `/api/v1/admin/uo-link` (`config`, `towncrier`, `stream`) | cookie (staff / admin) |
Post categories (URL form): `news`, `five-on-friday`, `newsletter`, `screenshots`.
`authMethod` on a session ∈ `local · totp · mobile · google · discord · oidc`.
See [BACKEND_DESIGN.md](BACKEND_DESIGN.md) §4 for the full contract, or the interactive Swagger
docs below for a per-endpoint reference (parameters, request bodies, response codes).
---
## API documentation (Swagger)
The full API is documented as an **OpenAPI 3.0** spec and served with **Swagger UI**:
| URL | What |
|---|---|
| `http://localhost:3000/api/docs` | Interactive Swagger UI (try-it-out, auth) |
| `http://localhost:3000/api/docs.json` | Raw OpenAPI 3.0 spec (JSON) |
Every endpoint is tagged and grouped (Auth, Auth · Mobile, Auth · SSO, Public, and the Admin
groups) with its summary, parameters, request body, security requirement, and the response codes it
actually returns (`400` validation, `401`/`403` auth, `404`, `409` conflicts, `429` rate limits, …).
**Authentication in the UI** — click **Authorize** and provide either:
- `cookieAuth` — the `uomm_token` session cookie (set automatically in the browser after
`POST /api/v1/auth/login`), or
- `bearerAuth` — a mobile access token from `POST /api/v1/auth/mobile/login` (sent as
`Authorization: Bearer <token>`).
**Regenerating the spec** — the spec is generated from `#swagger.*` annotations next to each route
(`server/src/router/**`) plus the shared definitions in `server/swagger/swagger.js`
([swagger-autogen](https://github.com/davibaltar/swagger-autogen)). The output
`server/swagger/swagger-output.json` is committed so the docs work with no build step. After adding
or changing a route, regenerate it:
```bash
cd server
npm run swagger # → server/swagger/swagger-output.json
```
If the generated spec is missing, the server logs a warning and simply disables `/api/docs` (it does
not crash).
---
## Shard integration (uo-link)
The site is wired to the live in-game world through **uo-link**, a standalone sidecar service that
runs next to the ServUO shard. Its source lives in a separate repo:
**[UOM/link](https://gitea.whitlocktech.com/UOM/link)**. uo-link speaks the shard's internals and
exposes a small, authenticated HTTP + WebSocket API; this website is a *client* of it. The shard
itself is never exposed to the internet — only the sidecar is, and only the website's backend talks
to it.
### How it works
```
ServUO shard ──▶ uo-link sidecar (UOM/link) ──▶ website backend ──▶ browser
REST + WebSocket, bearer-auth ingest + REST same-origin JSON/SSE
```
- **Connection is admin-managed, not env.** The sidecar's base URL, WebSocket URL, shared-secret
token, and protocol version are stored in the database (`uoLinkConfig`), edited from the
**Admin → Shard** panel. The token is **encrypted at rest** (AES-256-GCM) and is **write-only** in
the API — it is never returned to any client and never sent to the browser. Every call the backend
makes carries `Authorization: Bearer <token>` and an `X-UOLink-Version` header (a protocol
mismatch fails fast with `409` instead of being mis-parsed).
- **Live ingest (WebSocket).** When enabled, the backend opens an outbound WebSocket to the sidecar
and receives a stream of game events — `mob.login`/`logout`, `char.vitals`, `economy.supply`,
`vendor.sale`, `player.death`/`murdered`, `house.decay` (IDOC), staff `audit.*`/`cheat.*`,
`link.request`, and `server.hello`/`shutdown`. A single dispatcher (`utils/shardIngest.js`) routes
each event: state-changing kinds update `shard_online` / `shard_economy` / `shard_houses`; notable
kinds are appended to an append-only `shard_events` log; high-frequency kinds (vitals, supply
ticks) only update state and are not logged. A changed boot id on `server.hello` is detected as a
restart and stale "online" rows are cleared. On reconnect the backend backfills missed events via
the sidecar's `/history`.
- **Live round-trips (REST).** For point-in-time reads the backend calls the sidecar directly —
`/char/serial/:serial`, `/roster/:account`, `/vendors/:account`, `/economy`, `/history` — plus
commands `/link/confirm` and `/towncrier`. The REST client (`utils/uoLinkClient.js`) **never
throws**: every call returns `{ ok, data, status }`, so a shard that is down or mid-restart
degrades to a `503`/retry banner instead of a 500.
- **Fan-out to the browser.** Ingested events are pushed to browsers over **Server-Sent Events**.
Two channels exist: a **public** stream carrying only a safe allowlist of kinds, and an
**admin-only** stream that also includes sensitive kinds (staff audit, cheat detection, login
attempts, IPs). Sensitive kinds can never leak onto the public channel.
### Account linking
A player (or staff member) proves ownership of a game account without sharing any game credentials:
1. In game, the player runs **`[link`** and receives a one-time code.
2. On the website (Player portal, or Admin → Account for staff) they enter the code.
3. The backend confirms the code with the sidecar (`POST /link/confirm`), which permanently tags the
game account with the website user id, and mirrors the link locally in `shard_account_links`.
That mirror is the authorization basis for character reads: roster/vendor/character-sheet endpoints
are **ownership-checked** so a user only sees accounts they linked. **Admins may view any
character**; players and editor/moderator staff are limited to their own linked accounts.
### What each audience sees
| Surface | Endpoints | Who | Data |
|---|---|---|---|
| **Public** | `/api/v1/public/shard/*` (`status`, `feed`, `economy`, `online`, `idoc`, `stream`) | anyone | Shard up/down, gold-supply series, IDOC houses, a curated live feed, and **"Staff online"** — only players whose account is linked to a **staff** user (admin/editor/moderator), shown with name + map location. Linked *players* are never listed publicly; no vitals or account are exposed. |
| **Player** | `/api/v1/player/shard/*` (`link`, `accounts`, `roster/:account`, `vendors/:account`, `char/:serial`, `sales`) | logged-in player | Their own linked accounts: character rosters, character sheets, player-vendor snapshots, and recent vendor sales. |
| **Admin** | `/api/v1/admin/shard/*` (self-linking, same as player) · `/api/v1/admin/uo-link/*` (`config`, `towncrier`, `stream`) | staff / admin | Staff link their own accounts like players; **admins** additionally read *any* character's data, edit the sidecar connection config, publish/remove **town-crier** messages, and subscribe to the full event stream (incl. audit/cheat). |
The sidecar URL and token are set once in **Admin → Shard**; if uo-link is not configured (or the
shard is offline), every shard surface degrades gracefully — the public page still renders, showing
the shard as offline.

## Environment variables
Copy `.env.example` (Compose) or `server/.env.example` (local) and fill in. **`.env` is git-ignored.**
| Var | Default | Notes |
|---|---|---|
| `NODE_ENV` | `production` | |
| `PORT` | `3000` | server listens on `0.0.0.0:PORT` |
| `UPLOAD_DIR` | `<server>/uploads` | where post images are written (`/app/uploads`, volume-mounted, in Compose) |
| `DB_HOST` / `DB_PORT` | `db` / `3306` | `db` in Compose; `127.0.0.1` for local dev |
| `DB_NAME` / `DB_USER` / `DB_PASSWORD` | `uomysticmoon` / `uomm` / — | app database credentials |
| `DB_ROOT_PASSWORD` | — | MariaDB root (Compose only) |
| `JWT_SECRET` | — | **required** — long random string; signs session, mobile, and SSO-flow tokens |
| `JWT_EXPIRES_IN` | `1d` | web session token + cookie lifetime |
| `COOKIE_SECURE` | `auto` | `auto` = Secure only over HTTPS (works on LAN HTTP + Pangolin HTTPS) |
| `COOKIE_NAME` | `uomm_token` | |
| `SECRET_ENC_KEY` | — | **required in prod** — key for AES-256-GCM encryption of stored OAuth client secrets. Dev falls back to a key derived from `JWT_SECRET` (with a warning) |
| `APP_BASE_URL` | — | public base URL, used to build the SSO OAuth `redirect_uri` (`${APP_BASE_URL}/api/v1/auth/sso/:provider/callback`). Set in prod to match what you register with Google/Discord; if unset it is derived from the request (fine for local dev) |
| `MOBILE_ACCESS_TTL` | `15m` | mobile bearer **access** token lifetime (short-lived) |
| `MOBILE_REFRESH_TTL_DAYS` | `30` | mobile **refresh** token lifetime (long-lived, rotated on use) |
| `TRUST_PROXY` | `1` | reverse-proxy trust for correct `req.ip` / `req.secure` (rate limiting, backoff, bot-ban). Pin to the proxy hop's LAN IP in prod. A blanket `true` is rejected (coerced to `1`) to block `X-Forwarded-For` spoofing |
| `DEBUG_TRUST_PROXY` | `0` | `1` logs raw peer address + `X-Forwarded-For` + resolved `req.ip` per request (to verify/refresh the proxy IP). Noisy — leave off |
| `TOTP_ISSUER` | `UOMysticmoon` | label shown in authenticator apps for optional per-user 2FA |
| `TOTP_CHALLENGE_TTL` | `5m` | lifetime of the short-lived post-password "awaiting code" step |

| `CLIENT_ORIGIN` | `http://localhost:5173` | enables CORS in dev only |
| `LOG_LEVEL` / `FILE_LOG_LEVEL` | `info` / `debug` | console / file verbosity |
| `LOG_TO_FILE` / `LOG_DIR` / `LOG_FILE` | `true` / `<server>/logs` / `app.log` | log file (bind-mounted to `./logs` in Docker) |
| `ANNOUNCE_POLL_MS` | `15000` | how often the news-announcement dispatcher sweeps `announce_jobs` for due/retry legs (town crier + Discord) |
| `TOWNCRIER_DURATION_SEC` | `3600` | how long a news post's in-game town-crier message stays up (≤ `86400`) |
---
## Security
**Session & authorization**
- All auth flows go through one **session service** (`server/src/auth/`): controllers call
`sessionService.createSession(user, authMethod)` and middleware calls `validateSession()`, so web
cookies, mobile bearer tokens, and SSO all produce the *same* authenticated session model.
`utils/auth.js` remains a thin backward-compat facade.
- JWT in an httpOnly, `SameSite=Lax` cookie (`Secure` auto-detected), bcrypt password hashing.
- Admin routes are **re-validated against the database on every request**, so a demoted or deleted
user loses access immediately instead of keeping their old role until the token expires.
- **Role-based authorization** — admin-only endpoints (users, site mode, settings, auth providers)
are gated by a `requireRole` check, so a lower-privilege editor can't reach them.
**Mobile bearer auth**
- Native clients use `/api/v1/auth/mobile/*`: a short-lived **access token** (bearer JWT, validated
by the same middleware as the cookie) plus a long-lived, **server-stored, revocable refresh
token** that is **rotated on every refresh** (a replayed refresh token is single-use). Refresh
tokens are stored **hashed** (never in the clear); logout revokes one or all. Mobile login reuses
the same bot-scoring + backoff defenses as web, with single-request TOTP.
**Single sign-on (OAuth2 / OIDC)**
- Pluggable providers — built-in **Google** and **Discord** (endpoints fixed in code; admins supply
only client id/secret) plus fully-configurable **custom OIDC/OAuth2** providers, managed from the
**Authentication** admin panel. Only `enabled` + fully-configured providers are shown to users.
- **Link-only** by policy: an SSO login succeeds *only* if the external identity is already linked to
an existing account (linked by the user from **Account**). External identities are **never
auto-provisioned** — no one gains access without an account you created.
- The redirect flow is CSRF-protected with a signed, httpOnly, short-lived transaction cookie plus
**PKCE**; OAuth client secrets are **encrypted at rest** (AES-256-GCM) and never returned to any
client. SSO logins go through the same `sessionService`, so login/activity logging, RBAC, and bot
protection are identical to a local login.
**Login hardening**
- **Optional per-user TOTP two-factor** (opt-in, self-service on `/admin/account`). When enabled,
the password step issues only a short-lived, non-session `stage:'totp'` challenge; a session
cookie is granted only after the second factor verifies.
- **Login throttling** — `express-slow-down` + a hard rate cap + a separate per-IP exponential
backoff, with generic error messages that don't reveal whether the username exists.
- **Honeypot** field on the login form; submissions that fill it are treated as bots.
- **Bot-scoring + automatic IP ban** — weighted scoring of CMS-scanner paths and junk 404s (with a
periodic sweep of stale entries) bans hostile scanners; failed logins and honeypot hits feed the
score. Admins get visibility into this on the **Bot Activity** panel: currently banned IPs and a
recent-events feed (in-memory, most-recent-first), plus a logged emergency **unban** for false
positives — read + unban only, not a scoring-config surface.
**Uploads & input**
- Uploaded file extensions are derived from the **validated mimetype**, not the client-supplied
filename (prevents a disguised-extension upload).
- `express-validator` on all writes; usernames are validated **and** uniqueness-checked on update.
**Platform**
- `helmet`, admin routes `noindex` + `robots.txt` disallow, `trust proxy` for correct client IPs
behind Pangolin (see `TRUST_PROXY`), first admin seeded from env (no hardcoded credentials),
`.env` git-ignored. Passwords and request bodies are never logged. Email sends through Gmail
OAuth2 configured in the admin (refresh token stored AES-GCM-encrypted, never in env); the
contact form falls back to a `mailto:` link when unconfigured.
---
## Logging
Every log line goes to **both the console and a log file**, timestamped and leveled
(`error` / `warn` / `info` / `debug`):
```
2026-06-26T18:55:01.123Z INFO [server] listening on http://0.0.0.0:3000 ...
2026-06-26T18:55:09.880Z INFO [http] 192.168.1.40 admin POST /api/v1/auth/login 200 12 ms - 48 bytes
2026-06-26T18:55:14.402Z WARN [auth] login failed {"username":"root","ip":"192.168.1.40"}
2026-06-26T18:55:20.110Z ERROR [error] GET /api/v1/public/wiki -> 500 ... {"stack":"..."}
```
Captured: startup config banner, schema/seed steps, **HTTP access logs** (real client IP via
`trust proxy`, the authenticated admin, method/URL/status/time/size), login success/failure,
rate-limit hits, site-mode changes, all errors with stack traces, and graceful shutdown. Console
verbosity is `LOG_LEVEL`; the file keeps the fuller `FILE_LOG_LEVEL` record. In Docker the file is
bind-mounted to `./logs/app.log` and `docker compose logs -f app` shows the console stream.
---
## Deployment behind Pangolin
`docker compose up -d --build` exposes the `app` container on `0.0.0.0:3000` (no `127.0.0.1`
binding) so Pangolin can reach it. Point a Pangolin resource at `app:3000`. Because `COOKIE_SECURE`
defaults to `auto`, the admin login works both directly via the LAN IP over HTTP **and** through
Pangolin over HTTPS — no config change needed. MariaDB stays on the private Compose network
(no published port by default); data persists in the `dbdata` volume, uploads in `uploads`.
