rabbitmq-pika-adapter 0.2.1

Lightweight RabbitMQ client helpers (blocking/pika) with Sender and Listener utilities.

rabbitmq-pika-adapter

Lightweight RabbitMQ client helpers built on pika (sync) and aio-pika (async).

Core API:

• Sync publish: PublisherPool (recommended)
• Sync consume: Listener
• Async publish/consume: AsyncSender, AsyncListener (optional extra)
• Facade: RabbitMQClient (recommended entrypoint)

Acknowledgements (auto_ack)

Consumers support two acknowledgement modes:

• auto_ack=False (default): at-least-once delivery. The library will ack after your callback returns successfully, and nack/requeue on exception. Your handler should be idempotent because messages may be redelivered.
• auto_ack=True (legacy): at-most-once delivery. Messages are considered acknowledged on delivery. If your callback raises or the process crashes mid-processing, RabbitMQ will not redeliver that message.

Recommendation: for most "work queue" style consumers, use auto_ack=False.

See docs/USAGE.md for details and examples.

Installation

From PyPI:

pip install rabbitmq-pika-adapter

Async support:

pip install rabbitmq-pika-adapter[async]

This enables AsyncSender and AsyncListener.

Usage

Recommended entrypoint:

• RabbitMQClient(...).publisher(...) / .listener(...)

Direct usage (advanced/explicit):

• Listener(message_type, callback, ...) - thread-based consumer.
• PublisherPool(message_type, ...) - sync publisher with pooled channels.
• AsyncListener(message_type, callback, ...) - asyncio-based consumer.
• AsyncSender(message_type, ...) - asyncio-based publisher.

See examples/usage.py and docs/USAGE.md.

Examples

• High-throughput sync publish+consume demo (prints stats for both):

  python examples/usage.py throughput

Notes:

• The repo uses a src/ layout. If you want to run examples without installing the package, examples/usage.py will automatically add src/ to sys.path.

Testing

Install test deps:

pip install -e .[test]

Run unit tests:

python -m pytest -q

Integration tests (no Docker)

Integration tests are opt-in and require a reachable RabbitMQ. Set env vars:

• RABBITMQ_HOST (or RABBITMQ_SERVER)
• RABBITMQ_PORT
• RABBITMQ_VHOST
• RABBITMQ_USER
• RABBITMQ_PASSWORD

Then run:

python -m pytest -m integration -q

Publishing to PyPI

This repo publishes from GitHub Actions:

• Pushes to develop publish to TestPyPI.
• Pushes to release publish to PyPI.

Manual build/publish:

python -m pip install build twine
python -m build
python -m twine check dist/*
python -m twine upload dist/*
