Enhanced and flexible ASGI session middleware for Starlette applications

Starlette Session Middleware ·

Purpose

The purpose of this project is to provide an enhanced, more flexible ASGI session middleware

Getting started

In the project root, you will want to create and activate a Python virtual environment in a folder called .venv. On Fedora 38 this can be done by running python3.9 -m venv .venv && source .venv/bin/activate. You will then want to pip install all of the dependencies for local development. This can be done by running pip install -r requirements.txt in your Python 3.9 virtual environment. After that, you will want to run pre-commit install to install all of the pre-commit hooks. This ensures that we reduce unneeded pipeline failures.

Running the Tests

You can run the tests by running python -m pytest -n auto --cov. This will use pytest-xdist to parallelize the tests and provide a code coverage report by using pytest-cov.

Usage

FastAPI

In order to use a JWT persisted with a cookie and passed through a cookie, you would create the middleware as follows.

from fastapi import FastAPI
from starlette_session.middleware import SessionMiddleware
from starlette_session.middleware.codecbackends.jwt import JwtCodecBackend
from starlette_session.middleware.storagebackends.cookie import CookieStorageBackend
from starlette_session.middleware.authorizationbackends.cookie import CookieAuthorizationBackend


app = FastAPI()

app.add_middleware(
    SessionMiddleware,
    codec_backend=JwtCodecBackend(key="somesuperdupersecurekey")
    storage_backend=CookieStorageBackend()
    authorization_backend=CookieAuthorizationBackend()
)

In order to use a JWT persisted with a cookie and passed through the Authorization header, you would create the middleware as follows.

from fastapi import FastAPI
from starlette_session.middleware import SessionMiddleware
from starlette_session.middleware.codecbackends.jwt import JwtCodecBackend
from starlette_session.middleware.storagebackends.cookie import CookieStorageBackend
from starlette_session.middleware.authorizationbackends.authorizationheader import AuthorizationHeaderAuthorizationBackend


app = FastAPI()

app.add_middleware(
    SessionMiddleware,
    codec_backend=JwtCodecBackend(key="somesuperdupersecurekey")
    storage_backend=CookieStorageBackend()
    authorization_backend=AuthorizationHeaderAuthorizationBackend()
)
