sanic-session is session management extension forSanic that integrates server-backed sessions with most convenient API.

sanic-session provides a number ofsession interfaces for you to store a client's session data. The interfaces available right now are:

• Redis (supports both driversaioredis andasyncio_redis)
• Memcache (viaaiomcache)
• Mongodb (viasanic_motor andpymongo)
• In-Memory (suitable for testing and development environments)

Install withpip (there is other options for different drivers, check documentation):

pip install sanic_session

Documentation is available atsanic-session.readthedocs.io.

Also, make sure you readOWASP's Session Management Cheat Sheet for some really useful info on session management.

A simple example uses the in-memory session interface.

fromsanicimportSanicfromsanic.responseimporttextfromsanic_sessionimportSession,InMemorySessionInterfaceapp=Sanic(name="ExampleApp")session=Session(app,interface=InMemorySessionInterface())@app.route("/")asyncdefindex(request):# interact with the session like a normal dictifnotrequest.ctx.session.get('foo'):request.ctx.session['foo']=0request.ctx.session['foo']+=1returntext(str(request.ctx.session["foo"]))if__name__=="__main__":app.run(host="0.0.0.0",port=8000)

Examples of using redis and memcache backed sessions can be found in the documentation, underUsing the Interfaces.
