Relé makes integration with Google PubSub straightforward and easy.

Motivation and Features

The Publish-Subscribe pattern and specifically the Google Cloud Pub/Sub library are very powerful tools but you can easily cut your fingers on it. Relé makes integration seamless by providing Publisher, Subscriber and Worker classes with the following features:

• Powerful Publishing API
• Highly Scalable Worker
• Intuitive Subscription Management
• Easily Extensible Middleware
• Ready to go Django/Flask integration
• CLI
• And much more!

What it looks like

# Publish to the topic
import rele

rele.publish(topic='photo-uploaded', data={'customer_id': 123})

# Subscribe to the Pub/Sub topic
from rele import sub

@sub(topic='photo-uploaded')
def photo_uploaded(data, **kwargs):
    print(f"Customer {data['customer_id']} has uploaded an image")
