Description:

pyzeus 0.1.3

pyzeus ⚡
The cors middleware that enables a FastAPI server to handle cors requests. It also handles preflight requests 😃.
Installation
pip install pyzeus

or
pip3 install pyzeus

Default Response Headers
If no options are provided, the response headers will be as follows:
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET,HEAD,PUT,PATCH,POST,DELETE
Access-Control-Allow-Headers: Content-Type,Origin
Access-Control-Max-Age: 5

NOTES

The allow_headers will always append Content-Type and Origin to your response headers so no need to add it to the list
To handle preflight requests you will specifically need to add a @router.options(...) to your router

Usage Examples
Router Instance
This implementation is equally
from pyzeus import zeus
from fastapi import APIRouter, Depends

router = APIRouter(dependencies=[Depends(zeus().thunder)])

@router.get("/")
async def hander():
return { "message": "lorem ipsum" }

@router.options("/")
async def options_hander():
return None

Specific Route
This implements a sync or async agnostic decorator that requires you to add request and response parameters in your route handler. Worry not, it works if you have pydanyic classes too! Needs python 3.8+ or run pip install typing_extensions
from pyzeus import zeus
from fastapi import APIRouter, Depends

router = APIRouter()

# Synchronous example
@router.get("/")
@zeus().smite
def synchronous_handler(request: Request, response: Response):
return { "message": "lorem ipsum" }

# Asynchronous example
@router.get("/")
@zeus().smite
async def asynchronous_handler(request: Request, response: Response):
return { "message": "lorem ipsum" }

# Pydantic example
class Item(BaseModel):
name: str

@router.post("/")
@zeus().smite
async def asynchronous_handler(request: Request, response: Response, item: Item):
return { "message": item }
