A generic interface wrapping multiple backends to provide a consistent pubsub API.

Installation

------------

.. code-block:: bash

    pip install aio-pubsub

    # for redis backend

    pip install aio-pubsub[aioredis]

    # for postgresql backend

    pip install aio-pubsub[aiopg]

Usage

------

To use it, you need to implement your pubsub implementation from interfaces or use backends

from ``aio_pubsub.backends`` package

.. code-block:: python

    import asyncio

    from aio_pubsub.backends.memory import MemoryPubSub

    pubsub = MemoryPubSub()

    async def sender():

        """Publish a new message each second"""

        counter = 0

        while True:

            await pubsub.publish("a_chan", "hello world %s !" % counter)

            await asyncio.sleep(1)

            counter += 1

    async def receiver():

        """Print all message received from channel"""

        subscriber = await pubsub.subscribe("a_chan")

        async for message in subscriber:

            print("Received message: '%s'" % message)

    loop = asyncio.get_event_loop()

    loop.run_until_complete(

        asyncio.gather(sender(), receiver())

    )

    loop.close()

Supported backends

---------------------

``Disclaimer``: I would not advise you to use this backend, because it is shown only for testing purposes.

Better develop your own implementation.

* memory

* redis

* postgresql

* mongodb
