Sanic Cookie and Session Management

Project description

Build Status Software License

Sanic Cookies

Code here is mostly borrowed from sanic_session.

I wanted to make some changes that would break a big part of sanic_session's API, so I decided to create this repo instead.

Some of the main deviations from sanic_session are:

  1. Interfaces are only responsible for reading/writing the session_dict. Session management logic is handled by the session object

  2. No race conditions:

    By using:

     async with request['session']:
         request['session']['foo'] = 'bar'
    

    instead of:

     request['session']['foo'] = 'bar'
    

    It is still however possible to use the session_dict without a context manager, but it will raise some warnings, unless it's explicitly turned off (warn_lock=False)

  3. A more simple implementation of SessionDict that helps me sleep in peace at night. (Probably less performant)

  4. In memory interface schedules cleanup to avoid running out of memory

Quick Start

from sanic_cookies import Session, InMemory

interface = InMemory()
app = Sanic()
Session(app, master_interface=interface)

# You can skip this part if you don't want scheduled interface cleanup
@app.listener('before_server_start')
def init_inmemory(app, loop):
    interface.init()
@app.listener('after_server_stop')
def kill_inmemory(app, loop):
    interface.kill()

@app.route('/')
async def handler(request):
    async with request['session'] as sess:
        sess['foo'] = 'bar'

If enough people are interested, I can write some docs. Meanwhile, if you excuse me...

Gotta go fast!!
