Asynchronous message dispatcher for concurrent tasks processing

pyinsole is an asynchronous message dispatcher inpired by loafer designed to provide a flexible and efficient way to consume messages from Amazon SQS queues. The pyinsole simplifies the process of integrating with SQS by offering multiple consumption strategies, allowing you to choose the best approach for your application's needs.

💻 Usage

The script defines an asynchronous message handler function (my_handler) that will be invoked whenever a message is received from the SQS queue. The SQSRoute class is used to route messages from the example-queue to the handler.

Example Code

Here’s the main code that processes messages from the example-queue. The script will listen for messages on the example-queue, and for each message received, it will print the message content, associated metadata, and any additional keyword arguments.

import os

from pyinsole import Manager
from pyinsole.ext.aws import SQSRoute

async def my_handler(message: dict, metadata: dict, **kwargs):
    print(f"message={message}, metadata={metadata}, kwargs={kwargs}")
    return True

provider_options = {
    "endpoint_url": os.getenv("AWS_ENDPOINT_URL"),
    "options": {
        "MaxNumberOfMessages": 10,
        "WaitTimeSeconds": os.getenv("AWS_WAIT_TIME_SECONDS", 20),
    },
}

routes = [
    SQSRoute('example-queue', handler=my_handler, provider_options=provider_options),
]

if __name__ == '__main__':
    manager = Manager(routes)
    manager.run()

Running the Script

This setup allows you to easily process messages from an SQS queue using the pyinsole library. You can modify the my_handler function to implement your specific message processing logic.

1. Start LocalStack (or ensure you have access to AWS SQS). If you are using LocalStack, make sure it's running and the example-queue is created:

   aws --endpoint-url=http://localhost:4566 sqs create-queue --queue-name example-queue
   

2. Run the script:

   python your_script.py
   

3. Push some messages:

   aws --endpoint-url=http://localhost:4566 sqs send-message --queue-url http://localhost:4566/000000000000/example-queue --message-body "Your message body"
