Library for inter-service event-based communication
Project description
Inter-service event communication
This library handles inter (micro)services communication in a decoupled way using the event/observer pattern.
The code raises an event when something happens and that event fires notifications to the registered listeners.
Implemented notifications are:
- Celery task
- HTTP request
YAML file configuration
Can be configured with a yaml file like this, passed as initialization argument or in environment variable EVENTISC_CONFIG
name_prefix: myapp.
listeners:
- kind: http
event_name: myapp.user_created
url: http://notification-service.mycompany.com/send-welcome/
requests_kwargs:
auth: ["myuser", "password"]
request_format: json
data:
user_id: "{event_data['user'].id}"
email: "{event_data['user'].email}"
- kind: celery
event_name_regex: myapp[.].*_created
queue: foo_service
task_name: foo_handle_created
task_kwargs:
event_name: {event_name}
event_data: {event_data}
Usage
import eventisc
...
eventisc.trigger("user_created", {"user": user}) # Should fire both listeners
eventisc.trigger("foo_created", {"foo": "bar"}) # Should fire only celery
