Workflows 1.0: A Lightweight Framework for Agentic systems

  I notice that the python versions and typescript versions are pretty different. Python is sort of class based, with python magic decorators

      class MyWorkflow(Workflow):
          @step
          async def start(self, ctx: Context, ev: StartEvent) -> MyEvent:
              num_runs = await ctx.get("num_runs", default=0)
  

  whereas TS is sort of builder/function based

      import { createWorkflow } from "@llamaindex/workflow-core";
      
      const convertEvent = workflowEvent();
      
      const workflow = createWorkflow();
      
      workflow.handle([startEvent], (start) => {
        return convertEvent.with(Number.parseInt(start.data, 10));
  
  

  Is there reason for this? });

    yea good callout -- python workflows came first, and while we could have directly translated these, the ergonomics around classes in python are not exactly what JS/TS devs expect.

    So instead, the goal was to capture the spirit of event-driven workflows, and implement them in a more TS-native way and improve the dev-ux for those developers. This means it might be harder to jump between the two, but I'd argue most people are not doing that anyways.
