## Quick Start (Development)

### Prerequisites

- [Bun](https://bun.sh) ≥ 1.1
- A Minecraft server with RCON enabled (or use the provided `docker-compose.dev.yml`)

### 1. Clone and install

```bash
git clone https://github.com/your-org/cubeadmin.git
cd cubeadmin
bun install
```

### 2. Configure environment

```bash
cp .env.example .env.local
```

Edit `.env.local` — at minimum you need:

```env
BETTER_AUTH_SECRET=your-32-char-secret-here
MC_SERVER_PATH=/path/to/your/minecraft/server
MC_RCON_PASSWORD=your-rcon-password
```

### 3. Spin up a local Minecraft server (optional)

```bash
docker compose -f docker-compose.dev.yml up -d
```

This starts a Paper Minecraft server with RCON exposed on port 25575.

### 4. Run the development server

```bash
bun dev
```

Open [http://localhost:3000](http://localhost:3000). The first account you register automatically becomes the administrator.

---

## Deployment

### Option A — Docker Compose (recommended)

This is the easiest way to run CubeAdmin and a Minecraft server together on a single host.

#### 1. Create your environment file

```bash
cp .env.example .env
```

Fill in all required values (see [Environment Variables](#environment-variables) below).

#### 2. Start the stack

```bash
docker compose up -d
```

This starts three services:

| Service | Description | Port |
|---|---|---|
| `cubeadmin` | The admin panel | 3000 |
| `minecraft` | Paper Minecraft server | 25565 |
| `bluemap` | 3D world map (optional) | 8100 |

#### 3. Reverse proxy (recommended)

Put Nginx or Caddy in front of CubeAdmin on port 3000. Example Caddyfile:

```
cubeadmin.example.com {
    reverse_proxy localhost:3000
}
```

> **Important:** Socket.io requires WebSocket support. Ensure your proxy forwards the `Upgrade` header.

Nginx snippet:

```nginx
location / {
    proxy_pass http://localhost:3000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
}
```

#### 4. First login

Navigate to `https://your-domain.com` and register the first account — it is automatically granted the `superadmin` role.

---

### Option B — Bare Metal (Bun)

#### 1. Build

```bash
bun install
bun run build
```

#### 2. Run

```bash
NODE_ENV=production bun --bun run server.ts
```

The server binds to `0.0.0.0:3000` by default. Use `PORT` and `HOSTNAME` env vars to change this.

#### 3. Run as a systemd service

```ini
# /etc/systemd/system/cubeadmin.service
[Unit]
Description=CubeAdmin
After=network.target

[Service]
Type=simple
User=cubeadmin
WorkingDirectory=/opt/cubeadmin
ExecStart=/usr/local/bin/bun --bun run server.ts
Restart=on-failure
RestartSec=5
Environment=NODE_ENV=production
EnvironmentFile=/opt/cubeadmin/.env

[Install]
WantedBy=multi-user.target
```

```bash
systemctl daemon-reload
systemctl enable --now cubeadmin
```

---

## Database Migrations

CubeAdmin uses Drizzle ORM with a SQLite database. Migrations are applied automatically at startup via `lib/db/migrate.ts`.

To generate a new migration after changing `lib/db/schema.ts`:

```bash
bun run db:generate
```

> **Note:** `bun run db:migrate` (drizzle-kit) does not work with Bun's native `bun:sqlite` driver. Always apply migrations through the app startup migrator or manually with `bun:sqlite` scripts.

To open the Drizzle Studio database browser:

```bash
bun run db:studio
```

---

## Environment Variables

### Authentication

| Variable | Required | Default | Description |
|---|---|---|---|
| `BETTER_AUTH_SECRET` | **Yes** | — | Secret key used to sign sessions and tokens. Must be at least 32 characters. Generate one with `openssl rand -base64 32`. |
| `BETTER_AUTH_URL` | No | `http://localhost:3000` | The public base URL of the CubeAdmin app. Used by Better Auth to construct callback URLs. |
| `NEXT_PUBLIC_BETTER_AUTH_URL` | No | *(inferred from browser)* | Browser-side auth URL. Only needed if the public URL differs from what the browser can infer (e.g. behind a proxy). |
| `BETTER_AUTH_TRUSTED_ORIGINS` | No | `http://localhost:3000` | Comma-separated list of allowed origins for CORS and CSRF protection. Add your public domain in production. |

### Email (SMTP)

CubeAdmin sends email via any standard SMTP server — Gmail, Mailgun, Postfix, Brevo, Amazon SES, or your own self-hosted relay. Email is only used for team invitations and magic-link sign-in. The app starts without email configured; invitations will fail gracefully with a logged error.

| Variable | Required | Default | Description |
|---|---|---|---|
| `SMTP_HOST` | No* | — | SMTP server hostname (e.g. `smtp.gmail.com`, `smtp.mailgun.org`, `localhost`). Required for any email to be sent. |
| `SMTP_PORT` | No | `587` | SMTP server port. Common values: `587` (STARTTLS), `465` (TLS/SSL), `25` (plain, relay), `1025` (local dev). |
| `SMTP_SECURE` | No | `false` | Set to `true` to use implicit TLS (port 465). Leave `false` for STARTTLS (port 587) or plain. |
| `SMTP_USER` | No | — | SMTP authentication username. Leave unset for unauthenticated relay (e.g. local Postfix). |
| `SMTP_PASS` | No | — | SMTP authentication password or app-specific password. |
| `EMAIL_FROM` | No | `CubeAdmin <noreply@example.com>` | The `From` address on outgoing emails. Must be authorised by your SMTP provider to avoid spam filtering. |

#### Common SMTP configurations

**Gmail** (app password required — enable 2FA first):
```env
SMTP_HOST=smtp.gmail.com
SMTP_PORT=587
SMTP_SECURE=false
SMTP_USER=you@gmail.com
SMTP_PASS=your-app-password
EMAIL_FROM=CubeAdmin <you@gmail.com>
```

**Mailgun**:
```env
SMTP_HOST=smtp.mailgun.org
SMTP_PORT=587
SMTP_SECURE=false
SMTP_USER=postmaster@mg.yourdomain.com
SMTP_PASS=your-mailgun-smtp-password
EMAIL_FROM=CubeAdmin <noreply@yourdomain.com>
```

**Amazon SES**:
```env
SMTP_HOST=email-smtp.us-east-1.amazonaws.com
SMTP_PORT=587
SMTP_SECURE=false
SMTP_USER=your-ses-access-key-id
SMTP_PASS=your-ses-smtp-secret
EMAIL_FROM=CubeAdmin <noreply@yourdomain.com>
```

**Local dev with Mailpit** (catches all emails, no real sending):
```env
SMTP_HOST=localhost
SMTP_PORT=1025
SMTP_SECURE=false
# no SMTP_USER / SMTP_PASS needed
```
Run Mailpit with `docker run -p 1025:1025 -p 8025:8025 axllent/mailpit` and view emails at [http://localhost:8025](http://localhost:8025).

### Minecraft Server

| Variable | Required | Default | Description |
|---|---|---|---|
| `MC_SERVER_PATH` | No | `/opt/minecraft/server` | Absolute path to the Minecraft server directory on the host. CubeAdmin reads/writes files here and spawns the server process from this directory. |
| `MC_RCON_HOST` | No | `127.0.0.1` | Hostname or IP where the Minecraft RCON interface is listening. Use `minecraft` when running the Docker Compose stack. |
| `MC_RCON_PORT` | No | `25575` | TCP port for the Minecraft RCON interface. Must match `rcon.port` in `server.properties`. |
| `MC_RCON_PASSWORD` | **Yes*** | — | Password for the Minecraft RCON interface. Must match `rcon.password` in `server.properties`. Required for player management, whitelist, and scheduler features. |

*Only truly required if you want RCON-based features (player commands, scheduler). The app will start without it.

### Database

| Variable | Required | Default | Description |
|---|---|---|---|
| `DATABASE_PATH` | No | `./data/cubeadmin.db` | Path to the SQLite database file. The directory must exist and be writable. In Docker, this is mapped to a named volume. |

### Server

| Variable | Required | Default | Description |
|---|---|---|---|
| `PORT` | No | `3000` | TCP port the HTTP server listens on. |
| `HOSTNAME` | No | `0.0.0.0` | Hostname the HTTP server binds to. |
| `NODE_ENV` | No | `development` | Set to `production` for production deployments. Affects CSP headers, error verbosity, and Hot Module Replacement. |

### Optional / Advanced

| Variable | Required | Default | Description |
|---|---|---|---|
| `BLUEMAP_URL` | No | — | URL where BlueMap is accessible from the browser (e.g. `http://localhost:8100`). Enables the Map page. Configurable from the Server Settings UI as well. |
| `RATE_LIMIT_RPM` | No | `100` | Maximum number of API requests per minute per IP address. Applied to all `/api/*` routes by the middleware. |

---

## Role System

CubeAdmin has three roles:

| Role | Description |
|---|---|
| `superadmin` | Full access — server control, settings, team management, everything. Automatically granted to the first registered user. |
| `admin` | Can manage players, plugins, files, backups, and the scheduler. Cannot change server settings or manage team roles. |
| `moderator` | Read-only access to most sections. Can send console commands and manage players. |

Roles are assigned when inviting team members. The initial superadmin can promote/demote others from the Team page.

## Enabling RCON on Your Minecraft Server

Add these lines to your `server.properties`:

```properties
enable-rcon=true
rcon.port=25575
rcon.password=your-strong-password
broadcast-rcon-to-ops=false
```

Restart the Minecraft server after editing `server.properties`.

---

## Security Notes

- **Change the default `BETTER_AUTH_SECRET`** before going to production. A leaked secret allows anyone to forge session tokens.
- **Use a strong RCON password.** RCON has full server control — never expose RCON port 25575 to the public internet.
- **HTTPS in production.** Better Auth cookies are `Secure` in production; the app will not authenticate over plain HTTP.
- **`BETTER_AUTH_TRUSTED_ORIGINS`** — add your production domain to prevent CSRF attacks from other origins.
- The middleware (`proxy.ts`) enforces a strict Content Security Policy with per-request nonces. No inline scripts are permitted.
- All API routes are rate-limited to 100 requests/minute per IP by default.
