🚀 Quick Start

Prerequisites

• Web server with PHP 8.0+ (Apache or Nginx)
• PHP extensions: pdo_sqlite, curl, mbstring, json
• HTTPS recommended (required for camera access on mobile)

Installation

# 1. Clone the repository
git clone https://github.com/dadaloop82/dispensa.git
cd dispensa

# 2. Create configuration file
cp .env.example .env

# 3. Set permissions
chmod 755 data/
chmod 664 data/.gitkeep
chown -R www-data:www-data data/

# 4. Edit your configuration
nano .env

Configuration (.env)

# Required for AI features (get a key at https://aistudio.google.com/app/apikey)
GEMINI_API_KEY=your_api_key_here

# Optional: Bring! shopping list integration
BRING_EMAIL=your_email@example.com
BRING_PASSWORD=your_password

# Optional: Text-to-Speech for cooking mode
TTS_URL=http://your-home-assistant:8123/api/events/tts_speak
TTS_TOKEN=your_long_lived_token
TTS_ENABLED=true

Web Server Configuration

Apache (.htaccess)

The app works out of the box with Apache if placed in the web root or a subdirectory. Make sure mod_rewrite is enabled and AllowOverride All is set.

<Directory /var/www/html/dispensa>
    AllowOverride All
    Require all granted
</Directory>

Nginx

server {
    listen 80;
    server_name your-server.local;
    root /var/www/html/dispensa;
    index index.html;

    location /api/ {
        try_files $uri $uri/ =404;
        location ~ \.php$ {
            fastcgi_pass unix:/run/php/php8.2-fpm.sock;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
        }
    }

    # Deny access to sensitive files
    location ~ /\.env { deny all; }
    location ~ /data/ { deny all; }
    location ~ /backup\.sh { deny all; }
}

HTTPS Setup (Recommended)

Camera access requires HTTPS on most mobile browsers. Options:

• Let's Encrypt with Certbot (for public-facing servers)
• Self-signed certificate (for local network only)
• Reverse proxy (e.g., Caddy, Traefik) with automatic TLS

Cron Job (Optional)

Set up a cron job for smart shopping predictions:

# Run every 5 minutes
*/5 * * * * php /path/to/dispensa/api/cron_smart_shopping.php >> /path/to/dispensa/data/cron.log 2>&1

Backup (Optional)

The included backup.sh creates local daily backups of your database:

# Run daily at 3 AM
0 3 * * * /path/to/dispensa/backup.sh

🔒 Security Notes

• Credentials are stored in .env (server-side, never committed to Git)
• Database stays local — never pushed to remote repositories
• API keys are passed server-side only — never exposed to the browser
• The API uses parameterized SQL queries (PDO prepared statements) against injection
• Input validation on all inventory operations (quantity bounds, location whitelist)
• Consider adding authentication if the server is accessible from the internet

---

🛠️ Development

# Run PHP's built-in server for local development
php -S localhost:8080 -t /path/to/dispensa

# Check PHP syntax
php -l api/index.php
php -l api/database.php

The application uses no build tools — edit files directly and refresh.

📋 Roadmap

• Multi-language support (i18n)
• User authentication / multi-user support
• Docker container for easy deployment
• REST API documentation (OpenAPI/Swagger)
• Offline mode with service worker
• Export/import inventory data
• Notification system (Telegram, email) for expiring products
