Triggering workflows through events

[aswanthkrishna]

Hi, I just started exploring hatchet and looks very promising for my use case .

From a quick browse through the examples I have seen setting up workflows and manually triggering them.

I was wondering if it is possible to have multiple workflows listen to an event and programmatically create events from the sdk.

Hey @aswanthkrishna, when you define your workflows, you have to make it listen to the event and then You can trigger the workflow based on the event.

sample workflow code:

from hatchet_sdk import Hatchet
 
hatchet = Hatchet()
 
@hatchet.workflow(on_events=["user:create"])
class MyWorkflow:
    @hatchet.step()
    def step1(self, context):
        print("executed step1")
        pass
 
    @hatchet.step(parents=["step1"])
    def step2(self, context):
        print("executed step2")
        pass
