Quick Start

from application_sdk.application import BaseApplication
from application_sdk.workflows import WorkflowInterface
from application_sdk.activities import ActivitiesInterface

# Define your workflow
class MyWorkflow(WorkflowInterface):
    @staticmethod
    def get_activities(activities):
        return [activities.my_activity]

# Define your activities
class MyActivities(ActivitiesInterface):
    async def my_activity(self, workflow_args):
        # Activity implementation
        pass

# Create and start application
app = BaseApplication(name="my-app")
await app.setup_workflow(
    workflow_and_activities_classes=[
        (MyWorkflow, MyActivities)
    ]
)
await app.start(workflow_class=MyWorkflow)
