## Overview
<img align="right" src="https://raw.githubusercontent.com/rezwanahmedsami/catzilla/main/logo.png" width="250px" alt="Catzilla Logo" />

Catzilla is a modern Python web framework purpose-built for extreme performance and developer productivity.
At its heart is a sophisticated C HTTP engine—built using **libuv** and **llhttp**—featuring an advanced **trie-based routing system** that delivers O(log n) route lookup performance.

By exposing its speed-focused C core through a clean, Pythonic decorator API, Catzilla gives developers full control with minimal overhead.
Whether you're building **real-time AI applications**, **low-latency APIs**, or **high-throughput microservices**, Catzilla is engineered to deliver maximum efficiency with minimal boilerplate.

<br>


## ✨ Features

### Core Performance
- ⚡ **Hybrid C/Python Core** — Event-driven I/O in C, exposed to Python
- 🔥 **Advanced Trie-Based Routing** — O(log n) lookup with dynamic path parameters
- 🧱 **Zero Boilerplate** — Decorator-style routing: `@app.get(...)`
- 🔁 **Concurrency First** — GIL-aware bindings, supports streaming & WebSockets
- 📦 **Zero Dependencies** — Uses only Python standard library (no pydantic, no bloat!)

### Advanced Routing System
- 🛣️ **Dynamic Path Parameters** — `/users/{user_id}`, `/posts/{post_id}/comments/{comment_id}`
- 🚦 **HTTP Status Code Handling** — 404, 405 Method Not Allowed, 415 Unsupported Media Type
- 🔍 **Route Introspection** — Debug routes, detect conflicts, performance monitoring
- 📊 **Production-Grade Memory Management** — Zero memory leaks, efficient allocation

### Developer Experience
- 🧩 **Modular Architecture** — Add plugins, middleware, or extend protocols easily
- 🧪 **Comprehensive Testing** — 90 tests covering C core and Python integration
- 📖 **Developer-Friendly** — Clear documentation and contribution guidelines
- 🔧 **Method Normalization** — Case-insensitive HTTP methods (`get` → `GET`)

## 🚀 NEW in v0.2.0: Memory Revolution

**The Python Framework That BREAKS THE RULES**

### **"Zero-Python-Overhead Architecture"**
- 🔥 **30-35% Memory Efficiency** — Automatic jemalloc optimization
- ⚡ **C-Speed Allocations** — Specialized arenas for web workloads
- 🎯 **Zero Configuration** — Works automatically out of the box
- 📈 **Gets Faster Over Time** — Adaptive memory management
- 🛡️ **Production Ready** — Graceful fallback to standard malloc

### **Memory Features**
```python
app = Catzilla()  # Memory revolution activated!

# Real-time memory statistics
stats = app.get_memory_stats()
print(f"Memory efficiency: {stats['fragmentation_percent']:.1f}%")
print(f"Allocated: {stats['allocated_mb']:.2f} MB")

# Automatic optimization - no configuration needed!
```

### **Performance Gains**
- **Request Arena**: Optimized for short-lived request processing
- **Response Arena**: Efficient response building and serialization
- **Cache Arena**: Long-lived data with minimal fragmentation
- **Static Arena**: Static file serving with memory pooling
- **Task Arena**: Background operations with isolated allocation

# app.py
from catzilla import (
    Catzilla, Request, Response, JSONResponse, BaseModel,
    Query, Path, ValidationError
)
from typing import Optional
import asyncio

# Initialize Catzilla
app = Catzilla(
    production=False,      # Enable development features
    show_banner=True,      # Show startup banner
    log_requests=True      # Log requests in development
)

# Data model for validation
class UserCreate(BaseModel):
    """User creation model with auto-validation"""
    id: Optional[int] = 1
    name: str = "Unknown"
    email: Optional[str] = None

# Basic sync route
@app.get("/")
def home(request: Request) -> Response:
    """Home endpoint - SYNC handler"""
    return JSONResponse({
        "message": "Welcome to Catzilla v0.2.0!",
        "framework": "Catzilla v0.2.0",
        "router": "C-Accelerated with Async Support",
        "handler_type": "sync"
    })

# Async route with I/O simulation
@app.get("/async-home")
async def async_home(request: Request) -> Response:
    """Async home endpoint - ASYNC handler"""
    await asyncio.sleep(0.1)  # Simulate async I/O
    return JSONResponse({
        "message": "Welcome to Async Catzilla!",
        "framework": "Catzilla v0.2.0",
        "handler_type": "async",
        "async_feature": "Non-blocking I/O"
    })

# Route with path parameters and validation
@app.get("/users/{user_id}")
def get_user(request, user_id: int = Path(..., description="User ID", ge=1)) -> Response:
    """Get user by ID with path parameter validation"""
    return JSONResponse({
        "user_id": user_id,
        "message": f"Retrieved user {user_id}",
        "handler_type": "sync"
    })

# Route with query parameters
@app.get("/search")
def search(
    request,
    q: str = Query("", description="Search query"),
    limit: int = Query(10, ge=1, le=100, description="Results limit")
) -> Response:
    """Search with query parameter validation"""
    return JSONResponse({
        "query": q,
        "limit": limit,
        "results": [{"id": i, "title": f"Result {i}"} for i in range(limit)]
    })

# POST route with JSON body validation
@app.post("/users")
def create_user(request, user: UserCreate) -> Response:
    """Create user with automatic JSON validation"""
    return JSONResponse({
        "message": "User created successfully",
        "user": {"id": user.id, "name": user.name, "email": user.email}
    }, status_code=201)

# Health check
@app.get("/health")
def health_check(request: Request) -> Response:
    """Health check endpoint"""
    return JSONResponse({
        "status": "healthy",
        "version": "0.2.0",
        "async_support": "enabled"
    })

if __name__ == "__main__":
    app.listen(port=8000, host="0.0.0.0")
```

Run your app:

```bash
python app.py
```

Visit `http://localhost:8000` to see your blazing-fast API with **30% memory efficiency** in action! 🚀
