This a supported Redis Based Session Storage for you FastAPI Application, you can use it with any Session Backend.

Before doing that check that you install the pre-built requirements.

We use redis-py a Python client for Redis that is built on top of the Redis server.


  • Dependency injection to protect routes
  • Compatible with FastAPI's auto generated docs
  • Pydantic models for verifying session data
  • Abstract session backend so you can build one that fits your needs
  • Abstract frontends to choose how you extract the session ids (cookies, header, etc.)
  • Create verifiers based on the session data.
  • Compatible with any Redis Configuration.

Redis Configuration

Before setting up our Sessions Storage and our CRUD Backend, we need to configure our Redis Instance.

BasicConfig is a function help us setting up the Instance Information like Redis Link Connection or ID Name or Expiration Time.

Default Config

  • url of Redis: redis://localhost:6379/0
  • name of sessionId: ssid
  • generator function of sessionId: lambda :uuid.uuid4().hex
  • expire time of session in redis: 6 hours
import random
from datetime import timedelta
from authx.cache import basicConfig

    sessionIdGenerator=lambda: str(random.randint(1000, 9999)),

Sessions Functions

When it come to way of storing our sessions, we need to create a function that will be used to store our sessions.

Authx give the developer the choice of using between a pre setting Crud Functionalities like getSession or deleteSession..

Also a SessionStorage Class where we initial the connections and the functions to store and get or delete our sessions.

from typing import Any

from fastapi import Depends, FastAPI, Request, Response

from authx.core import (

app = FastAPI(title=__name__)"/setSession")
async def _setSession(
    request: Request, response: Response, sessionStorage: SessionStorage = Depends(getSessionStorage)
    sessionData = await request.json()
    setSession(response, sessionData, sessionStorage)

async def _setSession(session: Any = Depends(getSession)):
    return session"/deleteSession")
async def _deleteSession(
    sessionId: str = Depends(getSessionId), sessionStorage: SessionStorage = Depends(getSessionStorage)
    deleteSession(sessionId, sessionStorage)
    return None
