AWS Workflow Cron

Tip

This page is best viewed through the site search or through the AI.

Creates an AWS Lambda durable workflow and triggers it on a schedule using CronV2.

Since CronV2 accepts a Workflow, the setup is just:

sst.config.ts

const workflow = new sst.aws.Workflow("MyWorkflow", {
  handler: "src/workflow.handler",
});

new sst.aws.CronV2("MyCron", {
  schedule: "rate(1 minute)",
  function: workflow,
});

sst.config.ts

const workflow = new sst.aws.Workflow("MyWorkflow", {
  handler: "src/workflow.handler",
});

const cron = new sst.aws.CronV2("MyCron", {
  schedule: "rate(1 minute)",
  function: workflow,
});

src/workflow.ts

import { workflow } from "sst/aws/workflow";

export const handler = workflow.handler(async (event, ctx) => {
  await ctx.step("start", async ({ logger }) => {
    logger.info("Workflow invoked by cron.");
  });

  await ctx.wait("ten-seconds", { seconds: 10 });

  await ctx.step("finish", async ({ logger }) => {
    logger.info("Workflow finished.");
  });
});
