A generic interface wrapping multiple backends to provide a consistent pubsub API.
Installation
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
from aio_pubsub.backends.memory import MemoryPubSub
pubsub = MemoryPubSub()
# Create subscriber
subscriber = await pubsub.subscribe("a_chan")
# Push message
await pubsub.publish("a_chan", "hello world!")
await pubsub.publish("a_chan", "hello universe!")
# And listening channel
try:
async for message in subscriber:
print(message, flush=True)
except KeyboardInterrupt:
print("Finish listening")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.
