from redis import Redis

async def setup_session(request: Request) -> JSONResponse:
    request.session.update({"data": "session_data"})
    return JSONResponse({"session": request.session})


async def clear_session(request: Request):
    request.session.clear()
    return JSONResponse({"session": request.session})


def view_session(request: Request) -> JSONResponse:

routes = [

redis_client = Redis(host="localhost", port=6379)
app = Starlette(debug=True, routes=routes)

Using a custom backend

You can provide a custom backend to be used. This backend has simply to implement the interface ISessionBackend

class ISessionBackend(ABC):
    @abstractmethod
    async def get(self, key: str) -> Optional[dict]:
        raise NotImplementedError()

    @abstractmethod
    async def set(self, key: str, value: dict, exp_in_mins: str) -> Optional[str]:
        raise NotImplementedError()

    @abstractmethod
    async def delete(key: str) -> Any:
        raise NotImplementedError()
