Quick Start

Using the API Client

config = Configuration(host="http://localhost:8080")
client = ApiClient(configuration=config)
flow_api = FlowApi(client)

# Submit a workflow
response = flow_api.submit_flow(flow_definition)

Building a Worker (Component Server)

from stepflow_py.worker import StepflowServer, StepflowContext
import msgspec

class MyInput(msgspec.Struct):
    message: str

class MyOutput(msgspec.Struct):
    result: str

server = StepflowServer()

@server.component
async def my_component(input: MyInput, context: StepflowContext) -> MyOutput:
    return MyOutput(result=f"Processed: {input.message}")

if __name__ == "__main__":
    import asyncio
    asyncio.run(server.run())
