Workflow.sendEvent()

The .sendEvent() resumes execution when an event is sent.

Usage example​

run.sendEvent("event-name", { value: "data" });

Parameters​

eventName:

string
The name of the event to send

step:

Step
The step to resume after the event is sent

Returns​

workflow:

Workflow
The workflow instance for method chaining

Extended usage example​

import { mastra } from "./mastra";

const run = await mastra.getWorkflow("testWorkflow").createRunAsync();

const result = run.start({
  inputData: {
    value: "hello",
  },
});

setTimeout(() => {
  run.sendEvent("event-name", { value: "from event" });
}, 3000);

In this example, avoid using await run.start() directly, as it would block sending the event before the workflow reaches its waiting state.
