django-queuebie 0.5.0

A simple and synchronous message queue for commands and events for Django.

PyPI • GitHub • Full documentation

Creator & Maintainer: Beyonder Deutschland

Features

• Split up your business logic in commands and events
• Commands are imperatives telling your system what to do, events reflect that something has happened
• Register light-weight functions via a decorator to listen to your commands and events
• Message handlers receive the context of the message (command or event), providing an explicit API
• No magic, no side effects since the queue works synchronously

import dataclasses

from queuebie.runner import handle_message
from queuebie.messages import Command, Event
from queuebie import message_registry


# Example command
@dataclasses.dataclass(kw_only=True)
class BuyProduct(Command):
    product_id: int
    customer_id: int
    price: float
    currency: str


# Example event
@dataclasses.dataclass(kw_only=True)
class ProductBought(Event):
    product_id: int
    customer_id: int


# Example handler
@message_registry.register_command(BuyProduct)
def handle_buy_product(context: BuyProduct) -> Event:
    # Here lives your business logic

    return ProductBought(
        product_id=context.product_id,
        customer_id=context.customer_id,
    )


# Start queue and process messages
handle_message(
    BuyProduct(
        product_id=product.id,
        customer_id=customer.id,
        price=12.99,
        currency="EUR",
    )
)

Installation

• Install the package via pip:

  pip install django_queuebie

  or via uv:

  uv add django_queuebie

• Add module to INSTALLED_APPS within the main django settings.py:

INSTALLED_APPS = (
    # ...
    "queuebie",
)

Releasing a new version

Releases are fully automated. Push a version tag and the pipeline will build, sign with Sigstore, publish to PyPI via Trusted Publishing, and create a GitHub Release — no API tokens needed.

git tag v<version>          # e.g. git tag v1.2.3
git push origin v<version>

Tags must start with v. Tags without the prefix won't trigger the pipeline.

First-time setup

Before the pipeline can run for the first time, an admin must:

1. Create GitHub Environment pypi

   • Go to Settings → Environments → New environment, name it exactly pypi
   • Under Deployment branches and tags, add a tag rule with pattern v*
   • Optionally add required reviewers for a manual approval gate

2. Configure PyPI Trusted Publisher

   • Go to PyPI → Project settings → Publishing → Add a new publisher
   • Fill in: Owner ambient-innovation, Repository django-queuebie, Workflow release.yml, Environment pypi

Publish to ReadTheDocs.io

• Fetch the latest changes in GitHub mirror and push them
• Trigger new build at ReadTheDocs.io (follow instructions in admin panel at RTD) if the GitHub webhook is not yet set up.

Maintenance

Please note that this package supports the ambient-package-update. So you don't have to worry about the maintenance of this package. This updater is rendering all important configuration and setup files. It works similar to well-known updaters like pyupgrade or django-upgrade.

To run an update, refer to the documentation page of the "ambient-package-update".
