A modern Python web framework with **intuitive developer experience** and exceptional performance.

> **🎯 Modern DX**: Zero-config setup, database models with chainable queries, one-liner features, and clean architecture patterns - making Python web development incredibly productive.

## What is Zenith?

Zenith brings together **exceptional productivity**, **outstanding performance**, and **full type safety**:

- **🚀 Zero-config setup** - `app = Zenith()` just works with intelligent defaults
- **🏗️ Intuitive models** - `User.where(active=True).order_by('-created_at').limit(10)`
- **⚡ One-liner features** - `app.add_auth()`, `app.add_admin()`, `app.add_api()`
- **🎯 Enhanced DX** - No session management, ZenithModel handles it automatically
- **🏎️ High performance** - Fast async architecture with production-tested throughput
- **🛡️ Production-ready** - Security, monitoring, and middleware built-in

## 🚀 Zero-Config Quick Start

```bash
pip install zenithweb
```

```python
from zenith import Zenith
from zenith import Session  # Database session dependency
from zenith.db import ZenithModel  # Modern database models
from sqlmodel import Field
from pydantic import BaseModel
from typing import Optional

# 🎯 Zero-config setup - just works!
app = Zenith()

# ⚡ Add features in one line each
app.add_auth()    # JWT authentication + /auth/login
app.add_admin()   # Admin dashboard at /admin
app.add_api("My API", "1.0.0")  # API docs at /docs

# 🏗️ Modern models with chainable query patterns
class User(ZenithModel, table=True):
    id: Optional[int] = Field(primary_key=True)
    name: str = Field(max_length=100)
    email: str = Field(unique=True)
    active: bool = Field(default=True)

class UserCreate(BaseModel):
    name: str
    email: str
    active: bool = True

# 🎨 Clean routes with enhanced DX
@app.get("/")
async def home():
    return {"message": "Modern DX in Python!"}

@app.get("/users")
async def list_users():  # ✨ No session management needed!
    # Clean chaining: User.where().order_by().limit()
    users = await User.where(active=True).order_by('-id').limit(10).all()
    return {"users": [user.model_dump() for user in users]}

@app.post("/users")
async def create_user(user_data: UserCreate):
    # Clean API: User.create() - no session management!
    user = await User.create(**user_data.model_dump())
    return {"user": user.model_dump()}

@app.get("/users/{user_id}")
async def get_user(user_id: int):
    # Automatic 404 handling
    user = await User.find_or_404(user_id)
    return {"user": user.model_dump()}

# 🏃‍♂️ Run it
if __name__ == "__main__":
    import uvicorn
    uvicorn.run(app, host="127.0.0.1", port=8000)
```

Run with:
```bash
uvicorn main:app --reload
```

## 🎯 Modern DX Features

### 🚀 **Zero-Config Setup (for Development)**
```python
app = Zenith()  # Just works! No complex configuration needed
```
- **Intelligent defaults** - Development uses SQLite, auto-generated dev keys
- **Production ready** - Set `DATABASE_URL` and `SECRET_KEY` env vars for production
- **Automatic middleware** - Security, CORS, logging configured automatically
- **Environment-aware** - Uses `ZENITH_ENV` or intelligent detection

### 🏗️ **Intuitive Database Models**
```python
# Intuitive database operations - seamless chaining!
users = await User.where(active=True).order_by('-created_at').limit(10).all()
user = await User.find_or_404(123)  # Automatic 404 handling
user = await User.create(name="Alice", email="alice@example.com")
```
- **ZenithModel** - Modern ORM with chainable queries
- **Automatic sessions** - No manual database session management
- **Type-safe queries** - Full async support with SQLModel integration

### ⚡ **One-Liner Features**
```python
app.add_auth()     # JWT authentication + /auth/login endpoint
app.add_admin()    # Admin dashboard at /admin with health checks
app.add_api()      # API documentation at /docs and /redoc
```
- **Instant features** - Complex functionality in single lines
- **Production-ready** - Each feature includes monitoring and security
- **Configurable** - Sensible defaults with full customization options

### 🎯 **Clean Dependency Injection**
```python
@app.get("/users")
async def get_users(session: AsyncSession = Session):
    # Simple database session injection
    users = await User.all()  # ZenithModel uses the session automatically
    return users
```
- **Simple patterns** - `Session` for database, `Auth` for current user
- **Service injection** - `Inject(ServiceClass)` for business logic
- **Type-safe** - Full IDE support and autocompletion

### 🏎️ **High Performance**
- **Fast async architecture** - Thousands of requests per second
- **Production-tested** - Comprehensive benchmark suite validates throughput
- **Async-first** - Full async/await with Python 3.12+ optimizations
- **Optimized** - Connection pooling, slotted classes, efficient middleware

### 🛡️ **Production-Ready**
- **Security by default** - CSRF, CORS, security headers automatic
- **Built-in monitoring** - `/health`, `/metrics`, request tracing
- **Error handling** - Structured errors with proper HTTP status codes
- **Testing framework** - Comprehensive testing utilities included

### 🌐 **Full-Stack Support**
- Serve SPAs (React, Vue, SolidJS) with `app.spa("dist")`
- WebSocket support with connection management
- Static file serving with caching
- Database integration with async SQLAlchemy

## 📁 Project Structure

Clean organization with zero configuration:

```
your-app/
├── main.py         # app = Zenith() + routes
├── models.py       # ZenithModel classes
├── services.py     # Business logic (optional)
├── migrations/     # Database migrations (auto-generated)
└── tests/          # Testing with built-in TestClient
```

**Or traditional clean architecture:**
```
your-app/
├── main.py         # Application entry point
├── models/         # ZenithModel classes
├── services/       # Service classes with @Service decorator
├── routes/         # Route modules (optional)
├── middleware/     # Custom middleware
└── tests/          # Comprehensive test suite
```

## Performance

Zenith delivers **high-performance async request handling** with production-tested throughput.

**Run your own benchmarks:**
```bash
uv run pytest tests/performance/ -v
```

The framework is optimized with connection pooling, slotted classes, and efficient middleware. Performance varies by hardware, middleware configuration, and application complexity.
