    handlers,
    redis_host={
        "host": "localhost",
        "port": 6379,
        "db": 0,
        "password": None,
        "decode_responses": True,
    },
    cookie_secret="YOUR_SECRET_KEY",
)

---

Usage

Create a base handler:

import tornado
from tornado_auth_sessions import TornadoSessionsMixin


class BaseHandler(
    TornadoSessionsMixin,
    tornado.web.RequestHandler,
):
    pass

Example

Login

class LoginHandler(BaseHandler):
    def post(self):
        # authenticate user...
        self.set_session(user.id)
        self.redirect("/dashboard")

Protected route

class DashboardHandler(BaseHandler):
    def get(self):
        user_id = self.get_session()
        if not user_id:
            self.redirect("/login")
            return

        self.write(f"Welcome user {user_id}") 

Logout

class LogoutHandler(BaseHandler):
    def post(self):
        self.remove_session(user.id)
        self.redirect("/")

Authentication (Tornado Native)

This library integrates seamlessly with Tornado’s built-in authentication system via get_current_user.

Add this to your base handler:

def get_current_user(self):
    return self.get_session()
