## 🛠️ Installation

### Prerequisites

- Rust (latest stable)

- Node.js 18+ and pnpm

- SQLite (automatic setup)

- Docker (optional)

### Quick Start

1. **Clone the repository**:

   ```bash

   git clone 

   cd rust-gallery

   ```

2. **Backend setup**:

   ```bash

   # Build the Rust backend

   cargo build --release

   # Database migrations run automatically on first start

   ```

3. **Frontend setup**:

   ```bash

   cd src-ui

   pnpm install

   pnpm dev  # Development server

   # or

   pnpm build  # Production build

   ```

4. **Run the application**:

   ```bash

   # Backend (from root directory)

   cargo run --release

   # Frontend development (in src-ui/)

   pnpm dev

   ```

5. **Access the application**:

   - Development: `http://localhost:3000` (frontend) → `http://localhost:8000` (API)

   - Production: `http://localhost:8000` (serves both frontend and API)

### Docker Deployment

```bash

# Build and run

docker build -t rust-gallery .

docker run -p 8000:8000 -v /path/to/images:/build/images rust-gallery

# Access at http://localhost:8000

```

## ⚙️ Configuration

### Application Configuration (`Rocket.toml`)

```toml

[default]

address = "0.0.0.0"

port = 8000

workers = 16

keep_alive = 5

log_level = "normal"

[default.databases]

sqlite_database = { url = "db.sqlite" }

[default.limits]

forms = "64 kB"

json = "1 MiB"

# Custom configuration

images_dirs = ["/path/to/your/images"]

```

### Environment Variables

```bash

# Server Configuration

ROCKET_ADDRESS=0.0.0.0

ROCKET_PORT=8000

ROCKET_WORKERS=16

# Database

DATABASE_URL=db.sqlite

# Frontend (for development)

REACT_APP_API_URL=http://localhost:8000

```

### Performance Tuning

The application uses configurable constants for optimal performance:

```rust

// Cache configuration

pub const MAX_CACHE_CAPACITY: u64 = 10_000;

pub const CACHE_TTL_1_DAY: u64 = 86400;

pub const CACHE_TTL_4_DAYS: u64 = 345600;

// Image processing

pub const DEFAULT_THUMBNAIL_WIDTH: u32 = 150;

pub const DEFAULT_THUMBNAIL_HEIGHT: u32 = 150;

// Validation limits

pub const MAX_PAGINATION_SIZE: usize = 1000;

pub const MAX_ITEMS_PER_PAGE: usize = 1000;

pub const MAX_FOLDER_NAME_LENGTH: usize = 255;

```

## 🎯 Usage

### Image Management

1. **Browse Albums**: View organized photo collections

2. **Full-Screen Viewing**: PhotoSwipe integration with touch gestures

3. **Download Images**: Direct download with proper caching headers

4. **Tag Management**: Add/edit tags for images and albums

5. **Search & Filter**: Real-time filtering by tags and folders

6. **Random Discovery**: Random photo viewer for rediscovering content

### Performance Features

1. **Smart Caching**: Thumbnails cached client-side for instant loading

2. **Progressive Loading**: Images load as needed with preloading strategies

3. **Virtual Scrolling**: Smooth performance with large collections

4. **Lazy Loading**: Images load only when in viewport

### Error Handling Architecture

The application implements comprehensive error handling:

```rust

pub enum AppError {

    DatabaseError(diesel::result::Error),

    IoError(std::io::Error),

    ImageError(image::ImageError),

    NotFound(String),

    BadRequest(String),

    ValidationError(String),

    // Future-ready error types

    InternalError(String),

    Unauthorized(String),

}

```

All endpoints return proper HTTP status codes with JSON error responses.

## 🔒 Security Features

### DoS Protection

- **Image resize limits**: Maximum 4096x4096 pixels (16.7M pixels total)

- **Dimension validation**: Strict validation preventing resource exhaustion attacks

- **Request validation**: Parameter bounds checking on all endpoints

- **Pixel count limits**: Maximum total pixels validated to prevent memory attacks

### Input Validation

- **Hash validation**: Alphanumeric characters only, length 10-128 characters

- **Path traversal protection**: Folder names sanitized, no `..`, `/`, or `\` allowed

- **Pagination limits**: Maximum 1000 items per page to prevent resource exhaustion

- **Folder name length**: Maximum 255 characters

- **SQL injection protection**: Diesel ORM with parameterized queries

### Error Handling

- **Proper HTTP status codes**: 400 (Bad Request), 404 (Not Found), 500 (Internal Server Error)

- **Structured error responses**: JSON error messages with details

- **No information leakage**: Safe error messages without exposing internals

- **Graceful degradation**: Handles missing files and database errors cleanly

### Performance Security

- **Non-blocking I/O**: Image processing offloaded to dedicated thread pool

- **Concurrent access control**: Lock-free data structures prevent deadlocks

- **Cache TTL limits**: Automatic cache expiration prevents memory leaks

- **File existence checks**: Validates files before attempting operations
