aiorabbit 1.0.0a1

An AsyncIO RabbitMQ Client Library

aiorabbit is an opinionated AsyncIO RabbitMQ client for Python 3 (3.7+).

Project Goals

• To create a simple, robust RabbitMQ client library for AsyncIO development in Python 3.

• To make use of new features and capabilities in Python 3.7+.

• Remove some complexity in using an AMQP client by:

  • Abstracting away the AMQP channel and use it only as a protocol coordination mechanism inside the client.

  • Remove the nowait keyword to ensure a single round-trip pattern of behavior for client usage.

• To automatically reconnect when a connection is closed due to an AMQP exception/error.

  When such a behavior is encountered, the exception is raised, but the client continues to operate if the user catches and logs the error.

• To automatically create a new channel when the channel is closed due to an AMQP exception/error.

  When such a behavior is encountered, the exception is raised, but the client continues to operate if the user catches and logs the error.

• To ensure correctness of API usage, including values passed to RabbitMQ in AMQ method calls.

Example Use

The following demonstrates an example of using the library to publish a message with publisher confirmations enabled:

import asyncio
import datetime
import uuid

import aiorabbit

RABBITMQ_URL = 'amqps://guest:guest@localhost:5672/%2f'


async def main():
    async with aiorabbit.connect(RABBITMQ_URL) as client:
        await client.confirm_select()
        if not await client.publish(
                'exchange',
                'routing-key',
                'message-body',
                app_id='example',
                message_id=str(uuid.uuid4()),
                timestamp=datetime.datetime.utcnow()):
            print('Publishing failure')

if __name__ == '__main__':
    asyncio.get_event_loop().run_until_complete(main())
