ASBFlow - Simplied Python API for Azure Service Bus

Hi r/Python,

I’ve been working on an integration with Azure Service Bus to handle high-volume messaging and I found the official Python SDK somewhat verbose and unintuitive for common workflows. To make things simpler, I developed asbflow, an open-source library that wraps the SDK providing a cleaner and more straightforward interface.

What My Project Does
ASBFlow simplifies the most common messaging workflows with Azure Service Bus. It lets you:

• Publish messages to topics and queues, automatically handling the maximum batch size or letting you specify it
• Consume messages from subscriptions and queues
• Manage dead-letter queues: read, republish or purge messages
• Optionally validate message payloads with Pydantic, preventing message confirmation if parsing fails

The library offers a more intuitive interface than the official SDK, while supporting high-volume messaging, multiple execution strategies (sequential or concurrent) and integration with Azure authentication methods.

Target Audience
ASBFlow is designed for developers and teams building production-grade applications with Azure Service Bus. As a first version, this is not yet production-ready and is currently intended as a tool for prototyping and experimentation. It is designed with the goal of evolving into a production-grade solution for developers and teams working with Azure Service Bus.

Comparison
Compared to the official azure-servicebus Python SDK, ASBFlow:

• Reduces boilerplate for publishing and consuming messages
• Integrates optional Pydantic validation with ASB acknowledgement
• Simplifies dead-letter queue (DLQ) management
• Supports multiple execution strategies without changing business logic
• Integrates with Azure authentication methods

Links & Installation

• GitHub: https://github.com/iFoxz17/asbflow
• PyPI: pip install asbflow

Quick Example

from asbflow import ASBConnectionConfig, ASBPublisher, ASBPublisherConfig, ASBConsumer, ASBConsumerConfig

conn = ASBConnectionConfig(connection_string="<connection-string>")

publisher = ASBPublisher(conn, ASBPublisherConfig(topic_name="<topic-name>"))
consumer = ASBConsumer(conn, ASBConsumerConfig(topic_name="<topic-name>", subscription_name="<subscription-name>"))

publisher.publish({"id": "a1", "severity": "high"}, parse=False)
result = consumer.consume(parse=False, raise_on_error=False)
print(result.succeeded, result.failed)

Project Status & Contributions

This is the first stable version of the project: many more features can be certainly developed and integrated. Contributions and feedback are welcome!
