Quick Start

# Clone the repository
git clone https://github.com/lizzyman04/ntsava-app
cd ntsava-app

# Install dependencies
composer install

# Configure environment
cp .env.example .env
nano .env  # Add your database and domain settings

# Run database migrations (Phinx)
composer migrate

# Seed default plans into the database
composer seed

# Set up subdomains in your hosting panel
# - cdn.yourdomain.com -> /storage
# - api.yourdomain.com -> /public

# Start the application
composer dev

You're now running Ntsava CDN.

Documentation

Document Description Topics Covered
ARCHITECTURE.md System design & data models Database schema, Request flow, Component interaction, Security model
SETUP.md Installation & DNS configuration Requirements, Environment setup, Subdomain config, CDN integration
DEPLOYMENT.md Deployment & PoP strategies Multiple CDN providers, Edge nodes, Load balancing, Monitoring

CDN Integration

Ntsava is CDN-agnostic - it works with any CDN provider that supports origin pull. The architecture separates static file serving (cdn.yourdomain.com) from dynamic API operations (api.yourdomain.com), making it compatible with:

  • Cloudflare (recommended for free tier)
  • Bunny.net (best for video)
  • AWS CloudFront (for AWS ecosystems)
  • Akamai (enterprise)
  • Custom Varnish edge nodes

While Ntsava works with any CDN, the documentation and examples focus on Cloudflare because:

  • Free tier supports unlimited bandwidth
  • 300+ global PoPs
  • Built-in DDoS protection
  • Automatic HTTPS and HTTP/2
  • Simple configuration via DNS proxy

But you can use any provider - see DEPLOYMENT.md for alternative configurations.

Technology Stack

Category Technology Version Purpose
Framework Fluxor PHP ^1.0 File-based routing, MVC pattern, security-first
ORM Cycle ORM ^2.15 DataMapper pattern, Entity management
Database MySQL / PostgreSQL 5.7+ / 12+ Data persistence (agnostic, tested on both)
Image Processing GD Library PHP 8.1+ Resize, filters, format conversion
CDN Any provider - Global edge caching (Cloudflare, Bunny, AWS, Akamai)
Authentication Token-based - API security

Use Cases

Image/Media Hosting Platform 
Scenario: A photography portfolio website
Solution:
  - Users upload high-res images
  - CDN serves optimized versions
  - On-the-fly resizing for thumbnails
  - WebP conversion for modern browsers
  - 90% bandwidth savings
Software Distribution 
Scenario: Distributing large files (ISOs, updates)
Solution:
  - Global edge caching
  - Resumable downloads support
  - Bandwidth quotas per user
  - Analytics dashboard
  - 95% reduction in origin load

Security Features

Authentication:
  - Token-based: X-User-UUID + X-Token headers
  - Password hashing: bcrypt (cost factor 10+)
  - Session management: Secure cookies, HTTP-only

Authorization:
  - Granular permissions: upload, delete, read
  - Per-token expiration: configurable TTL
  - Role-based: admin, moderator, user

Data Protection:
  - Input validation: All user inputs sanitized
  - SQL injection: ORM parameter binding
  - XSS prevention: Output encoding
  - CSRF protection: Token validation

File Security:
  - MIME type validation: Whitelist approach
  - Malware scanning: Content inspection
  - Path traversal: Directory sanitization
  - PHP execution: Blocked in storage

Database Schema Overview

users ──┬── files (owns)
        ├── api_tokens (has)
        ├── credits (has)
        ├── user_roles (assigned)
        └── plans (subscribes)

credits ──┬── credit_transactions (generates)
users ────┴── notifications (receives)

Key tables:
  - users: UUID, email, plan_id, storage_used_bytes, bandwidth_used_bytes
  - files: user_id, uuid, storage_path, size_bytes, mime_type, deleted_at
  - api_tokens: user_id, token_hash, permissions, expires_at
  - plans: slug, storage_limit_bytes, bandwidth_limit_bytes, max_file_size_bytes, allowed_mime_types, price

Examples

Upload a File

curl -X POST https://api.yourdomain.com/api/v1/upload \
  -H "X-User-UUID: 550e8400-e29b-41d4-a716-446655440000" \
  -H "X-Token: your-secret-token" \
  -F "file=@/path/to/image.jpg" \
  -F "path=gallery/2026"

Response:

{
  "success": true,
  "data": {
    "url": "https://cdn.yourdomain.com/u/johndoe/gallery/2026/image_a1b2c3.jpg",
    "uuid": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
    "size": 245760,
    "size_mb": 0.23,
    "mime": "image/jpeg",
    "path": "gallery/2026/image_a1b2c3.jpg"
  }
}
