🔍 Type Safety: First-class support for Python type hints and Pydantic validation
📚 OpenAPI Integration: Automatic Swagger/ReDoc documentation generation
🏗️ Modular Architecture: Organize code into reusable modules inspired by NestJS
🔐 Built-in Security: Comprehensive authentication and authorization system
🎨 Template Support: Integrated Jinja2 templating for server-side rendering
🔌 WebSocket Support: Real-time bidirectional communication capabilities
🧪 Testing Utilities: Comprehensive testing tools for unit and integration tests

🚀 Quick Start

Installation

pip install ellar

Basic Example

from ellar.common import get, Controller, ControllerBase
from ellar.app import AppFactory
import uvicorn

@Controller()
class HomeController(ControllerBase):
    @get('/')
    async def index(self):
        return {'message': 'Welcome to Ellar Framework!'}

app = AppFactory.create_app(controllers=[HomeController])

if __name__ == "__main__":
    uvicorn.run("main:app", port=5000, reload=True)

📚 Complete Example

from ellar.common import Body, Controller, ControllerBase, delete, get, post, put, Serializer
from ellar.di import injectable, request_scope
from ellar.app import AppFactory
from pydantic import Field

# Define Data Model
class CreateCarSerializer(Serializer):
    name: str
    year: int = Field(..., gt=0)
    model: str

# Define Service
@injectable(scope=request_scope)
class CarService:
    def __init__(self):
        self.detail = 'car service'

# Define Controller
@Controller
class CarController(ControllerBase):
    def __init__(self, service: CarService):
        self._service = service
    
    @post()
    async def create(self, payload: Body[CreateCarSerializer]):
        result = payload.dict()
        result.update(message='Car created successfully')
        return result

    @get('/{car_id:str}')
    async def get_one(self, car_id: str):
        return f"Retrieved car #{car_id}"

app = AppFactory.create_app(
    controllers=[CarController],
    providers=[CarService]
)
