abs-utils 0.4.0

AutoBridge Systems Utility Library

Utils Package

This package provides utility functions and classes for common operations in the application, including logging and Azure Service Bus integration.

Installation

The package is managed using Poetry. To install dependencies:

poetry install

Features

Logger

A simple logging utility that provides a standardized way to set up logging across the application.

Usage

from abs_utils.logger import setup_logger

# Create a logger instance
logger = setup_logger("my_module")

# Use the logger
logger.info("This is an info message")
logger.error("This is an error message")

Azure Service Bus Integration

Provides functionality to interact with Azure Service Bus for message queuing and event handling.

AzureServiceBus Class

A wrapper class for Azure Service Bus operations.

from abs_utils.azure_service_bus import AzureServiceBus

# Initialize the service bus client
service_bus = AzureServiceBus(
    connection_string="your_connection_string",
    queue_name="your_queue_name"
)

# Send a message
await service_bus.send({"key": "value"})

Event Decorator

A decorator that automatically sends events to Azure Service Bus after function execution. This is particularly useful for tracking entity operations in your application.

from fastapi import APIRouter, Depends, Request
from dependency_injector.wiring import inject, Provide
from abs_utils.azure_service_bus import azure_event_decorator, AzureServiceBus

router = APIRouter()

@router.post("/{entity_name}/records")
@inject
@azure_event_decorator(event_type="record_created")
async def create_record(
    entity_name: str,
    data: dict,
    request: Request,
    azure_service_bus: AzureServiceBus = Depends(Provide[Container.azure_service_bus]),
    service: YourService = Depends(Provide[Container.yourService])
):
    # Your function logic here
    return await service.create(data, entity_name)

The decorator automatically creates and sends an event payload with the following structure:

{
    "event_id": "uuid",
    "event_type": "record_created",
    "entity_name": "your_entity_name",
    "entity_id": "record_id",
    "payload": {
        // Your data payload
    },
    "user": {
        "id": "user_id",
        "uuid": "user_uuid",
        "email": "user_email",
        "name": "user_name"
    }
}

Key features of the decorator:

1. Automatically captures the entity name from the route parameters
2. Extracts user information from the request state
3. Generates a unique event ID for each event
4. Handles errors gracefully with logging
5. Works seamlessly with FastAPI dependency injection
