# event-bus
[](https://github.com/hvuhsg/event-bus/actions/workflows/test.yml)
EventBus implementation in python
### Examples
#### sync
```python
from multi_event_bus import EventBus
eb = EventBus(redis_host="127.0.0.1", redis_port=6379)
eb.dispatch("event-name", payload={"num": 1})
eb.subscribe_to("event-name", consumer_id="consumer-1", offset=0)
event, topic = eb.get(consumer_id="consumer-1") # Blocking
print(event.payload) # -> {"num": 1}
```
#### async
```python
from multi_event_bus import AsyncEventBus
eb = AsyncEventBus(redis_host="127.0.0.1", redis_port=6379)
eb.dispatch("event-name", payload={"num": 1})
eb.subscribe_to("event-name", consumer_id="consumer-2", offset=0)
event, topic = await eb.get(consumer_id="consumer-2")
print(event.payload) # -> {"num": 1}
```
#### register event schema
```python
from multi_event_bus import EventBus
eb = EventBus(redis_host="127.0.0.1", redis_port=6379)
# Enforce json schema of event
json_schema = {
"type": "object",
"properties": {"num": {"type": "string"}}
}
eb.register_event_schema("event-name", schema=json_schema)
eb.dispatch("event-name", payload={"num": "7854"})
eb.subscribe_to("event-name", consumer_id="consumer-3", offset=0)
event, topic = eb.get(consumer_id="consumer-3") # Blocking
print(event.payload) # -> {"num": "7854"}
```
