Creating a Simple Workflow

A workflow allows you to define and execute sequences of operations in a structured path. This example shows a workflow with a single step.


import { Step, Workflow } from "@mastra/core/workflows";
import { z } from "zod";
 
const myWorkflow = new Workflow({
  name: "my-workflow",
  triggerSchema: z.object({
    input: z.number(),
  }),
});
 
const stepOne = new Step({
  id: "stepOne",
  inputSchema: z.object({
    value: z.number(),
  }),
  outputSchema: z.object({
    doubledValue: z.number(),
  }),
  execute: async ({ context }) => {
    const doubledValue = context?.triggerData?.input * 2;
    return { doubledValue };
  },
});
 
myWorkflow.step(stepOne).commit();
 
const { runId, start } = myWorkflow.createRun();
 
const res = await start({
  triggerData: { input: 90 },
});
 
console.log(res.results);
