Introduction to Flowfull

Welcome to Flowfull - the fastest way to build production-ready backends with the Pubflow architecture!

What is Flowfull?

Flowfull is your custom backend layer that connects to Pubflow for authentication. It's designed to help you build scalable, secure backends in record time by providing:

• ✅ Pre-built authentication - No need to build login, registration, sessions
• ✅ Trust-based validation - Secure session validation with Bridge Validation
• ✅ Advanced caching - 3-tier HybridCache for lightning-fast performance
• ✅ Multi-database support - PostgreSQL, MySQL, LibSQL/Turso
• ✅ Language agnostic - Portable concepts for Node.js, Go, Python, Rust
• ✅ Production ready - Battle-tested patterns and security

The Pubflow Ecosystem

Flowfull is part of a complete architecture:

The Three Layers

1. 🔐 Flowless - Core authentication backend

   • Deployed on Pubflow
   • Handles all authentication (login, registration, sessions)
   • Managed service - no setup required
   • Validates sessions for your Flowfull backend

2. ⚡ Flowfull - Your custom backend (this documentation)

   • Connects to Flowless via Bridge Validation
   • Implements your business logic and APIs
   • Manages your database and cache
   • Stateless and horizontally scalable

3. 🎨 Flowfull-Client - Your frontend

   • React, Next.js, React Native, or any framework
   • Connects to your Flowfull backend
   • Uses Pubflow authentication seamlessly

Why Flowfull?

🚀 Build in Record Time

Instead of spending weeks building authentication, validation, and security:

// Traditional approach (weeks of work)
- Build user registration ❌
- Build login system ❌
- Build session management ❌
- Build password reset ❌
- Build email verification ❌
- Build security layers ❌
- Build caching system ❌

// Flowfull approach (30 minutes)
import { requireAuth } from './lib/auth/middleware';

app.get('/api/profile', requireAuth(), async (c) => {
  const userId = c.get('user_id');  // ✅ Done!
  return c.json({ profile: await getProfile(userId) });
});

⚡ Lightning Fast Performance

3-tier HybridCache system:

• 97% cache hit rate in production
• 50x faster responses (1-2ms vs 50ms)
• Automatic fallback (LRU → Redis → Database)
• Horizontal scaling with shared Redis cache

🔐 Enterprise Security

6-layer security validation:

1. PASETO signature verification (Ed25519)
2. Expiration check
3. Redis status check
4. Database status check
5. User ownership validation
6. Resource validation

🌍 Language Agnostic

Portable concepts that work in any language:

• Flowfull-Node.js - TypeScript/JavaScript (Bun, Node.js)
• Flowfull-Go - Go implementation
• Flowfull-Python - Python/FastAPI implementation
• Flowfull-Rust - Rust implementation

Core Concepts

Flowfull is built on 7 portable concepts:

1. Bridge Validation - Distributed authentication
2. Validation Modes - Layered security
3. HybridCache - 3-tier caching
4. Trust Tokens - PASETO tokens
5. Auth Middleware - Route protection
6. Multi-Database - Database abstraction
7. Environment Config - Configuration management

Real-World Usage

Flowfull concepts are used in many production systems worldwide:

• Gaming platforms - High-traffic applications with millions of requests per day
• SaaS applications - Multi-tenant systems with complex authentication
• E-commerce platforms - Payment processing and order management
• Enterprise systems - Internal tools and business applications
