Project Description


Loafer is an asynchronous message dispatcher for concurrent tasks processing.

Currently, only AWS SQS is supported

Features:

  • Encourages decoupling from message providers and consumers
  • Easy to extend and customize
  • Easy error handling, including integration with sentry
  • Easy to create one or multiple services
  • Generic Handlers
  • Amazon SQS integration

It requires Python 3.5+ and is very experimental at the moment, expect a lot of changes until the first major version.

Example

A simple message forwader, from source-queue to destination-queue:

from loafer.ext.aws.handlers import SQSHandler
from loafer.ext.aws.routes import SQSRoute
from loafer.managers import LoaferManager


routes = [
    SQSRoute('source-queue', handler=SQSHandler('destination-queue'),
]


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