Sending events from invoked async function

[daring topaz]

I have an asynchronous function that runs a loop from which I want to grab updated data for each iteration. Is it possible to send an event to the machine that invoked the async function in the way one can use sendParent() from an invoked machine?

You can invoke a callback to do this:

invoke: {
  src: (ctx, ev) => (sendBack) => {
    // do anything here; e.g. call an async function
    sendBack({ type: 'someEvent', data: ... })
  }
}
