# Website — Architecture
|
||||
|
||||
How the pieces of `RunicGateway/website` fit together. The React SPA and the native mobile app
|
||||
talk to one Express backend (`router → controller → model → db`), which persists to MariaDB and
|
||||
bridges to the live game world **only** through the **uo-link** sidecar. The ServUO shard itself is
|
||||
never internet-facing — it dials out to the sidecar over loopback, and only the sidecar is exposed.
|
||||
|
||||
This is the canonical copy of the diagram; the same diagram is embedded in the website's
|
||||
[`README.md`](https://gitea.whitlocktech.com/RunicGateway/website/src/branch/main/README.md#architecture).
|
||||
See [BACKEND_DESIGN.md](BACKEND_DESIGN.md) for the full API / schema / security contract, and
|
||||
[`docs/link/`](../link/) for the wire protocol between the sidecar and the shard.

## Notes on the diagram
|
||||
|
||||
- **One backend, layered.** Every request flows `middleware → router → controller → model → db`.
|
||||
Web browsers authenticate with an httpOnly JWT cookie; the native app uses short-lived bearer
|
||||
access tokens plus rotated, hashed, revocable refresh tokens; SSO (Google/Discord/OIDC) is
|
||||
link-only and PKCE-guarded. All three surfaces resolve to the *same* session model via the session
|
||||
layer, and admin routes are re-validated against the DB on every request.
|
||||
- **The shard is never reachable.** The ServUO shard *dials out* over loopback TCP `127.0.0.1:7788`
|
||||
(newline-delimited JSON) to the uo-link sidecar; only the sidecar is exposed, and only the backend
|
||||
talks to it. Every backend→sidecar call carries `Authorization: Bearer <token>` and an
|
||||
`X-UOLink-Version` header (a protocol mismatch fails fast with `409`). The REST client
|
||||
(`uoLinkClient.js`) never throws — every call returns `{ ok, data, status }` — so the site degrades
|
||||
gracefully when the shard is down.
|
||||
- **Two ways in from the sidecar.** Live game events arrive over an outbound **WebSocket** and are
|
||||
routed by the `shardIngest.js` dispatcher (state-changing kinds update `shard_*` tables, notable
|
||||
kinds append to `shard_events`, high-frequency kinds only update state). Point-in-time reads and
|
||||
commands go over **REST** through `uoLinkClient.js`.
|
||||
- **Sensitive events stay private.** Ingested events fan out to browsers over two **SSE** channels —
|
||||
a public allowlist stream and an admin-only stream that additionally carries staff audit, cheat
|
||||
detection, and login-attempt events. The allowlist split is a security boundary; sensitive kinds
|
||||
can never leak onto the public channel.
|
||||
- **Secrets at rest.** OAuth client secrets, the uo-link token, and the Gmail refresh token are
|
||||
AES-256-GCM encrypted via `secretBox.js` (keyed by `SECRET_ENC_KEY`). The uo-link token is
|
||||
write-only in the API — never returned to any client.
