# MineSeeker

A real-time **1v1 multiplayer minesweeper** game played in the browser.
Two players race on the same hidden minefield — uncover safe cells to score points, but hit a mine and you hand the advantage to your opponent.
Games are live and synchronised instantly via a Mercure hub; no page reloads, no polling.

## Features

- **Real-time 1v1 gameplay** — moves broadcast instantly over Mercure (server-sent events)
- **Guest & registered play** — jump in anonymously or create an account for stats and history
- **Full authentication stack** — email/password, passkeys (WebAuthn), TOTP 2FA with backup codes
- **Player profiles** — win/loss/draw stats, per-month charts, recent battle history with shareable replay links
- **Profile pictures** — uploaded to MinIO object storage, thumbnails generated on-the-fly by LiipImagine
- **Battle replay sharing** — share a direct link to any finished game
- **Docker-ready** — single `make start-build` brings up the full production-like stack

## Requirements

### Bare-metal development
- PHP >= 8.5 with extensions: `pdo_pgsql`, `gd`, `intl`, `zip`, `sodium`
- Composer 2
- Node.js 22 + Bun
- PostgreSQL 18
- Caddy with FrankenPHP and the Mercure module
- MailHog (or any SMTP server on port 1025)
- MinIO (listening on port 9000)

### Docker
- Docker Engine 24+
- Docker Compose v2
- Bun (for building frontend assets before `make start-build`)
- Composer (for `make start-build`)

---

## Installation

### 1. Clone the repository

```bash
git clone https://github.com/splendidbear/mineseeker.git
cd mineseeker
```

### 2. Configure environment

```bash
cp .env.dist .env
```

Edit `.env` and fill in every value. Key ones:

| Variable | What to set |
|---|---|
| `APP_SECRET` | Random 32-byte hex: `openssl rand -hex 32` |
| `POSTGRES_USER/PASSWORD/DB` | Your PostgreSQL credentials |
| `MINIO_ROOT_USER/PASSWORD` | MinIO admin credentials |
| `MINIO_ENDPOINT` | `http://localhost:9000` (bare-metal) |
| `MINIO_PUBLIC_URL` | Public URL browsers use to reach MinIO |
| `RECAPTCHA_SITE_KEY/SECRET_KEY` | Google reCAPTCHA v3 keys for your domain |
| `MERCURE_JWT_SECRET` | Random secret (generated in step 3) |
| `MERCURE_JWT_TOKEN` | Signed publisher JWT (generated in step 3) |
| `MERCURE_SUBSCRIBER_JWT` | Signed subscriber JWT (generated in step 3) |
| `MAILER_DSN` | `smtp://localhost:1025` for MailHog in dev |

### 3. Generate Mercure JWT tokens

```bash
composer install
make mercure-jwt
```

Copy the printed values into `.env` and into the `publisher_jwt` / `subscriber_jwt` lines of your Caddy Mercure block, then reload Caddy:

```bash
sudo systemctl reload caddy
```

### 4a. Run with Docker

```bash
make start-build
```

This installs PHP dependencies, builds the frontend assets with Bun, builds the Docker image, and starts all services (`app`, `db`, `mail`, `minio`, `minio_init`).

The app is available at `http://localhost:10080` (or the domain set in `APP_PUBLIC_HOSTNAME`).

To apply any code changes later, run the same command again.

### 4b. Run bare-metal (development)

```bash
composer install
bun install
bun run dev            # Vite dev server with hot-reload
php bin/console doctrine:migrations:migrate --no-interaction
```

Start MinIO and MailHog, then open the URL configured in your Caddy vhost.

### 5. MinIO bucket setup

**Docker** — handled automatically on first start by the `minio_init` service. No action needed.

**Bare-metal** — run once after MinIO is up:

```bash
mc alias set local http://localhost:9000 $MINIO_ROOT_USER $MINIO_ROOT_PASSWORD
mc mb local/mineseeker
echo '' | mc pipe local/mineseeker/media/.keep
echo '' | mc pipe local/mineseeker/cache/.keep
# Apply public-read policy for media/ and cache/ — see docker/minio-init.sh for the JSON
```
