Sleep step.sleep()

Use step.sleep() to pause the execution of your function for a specific amount of time. At maximum, functions can sleep for a year (seven days for the free tier plans).

Functions that are sleeping do not count towards concurrency limits.

export default inngest.createFunction(
  { id: "send-delayed-email" },
  { event: "app/user.signup" },
  async ({ event, step }) => {
    await step.sleep("wait-a-couple-of-days", "2d");
    // Do something else
  }
);

To sleep until a particular date time, use step.sleepUntil() instead.

step.sleep(id, duration): Promise

  • Name
    id
    Type
    string
    Required
    required
    Description

    The ID of the step. This will be what appears in your function's logs and is used to memoize step state across function versions.

  • Name
    duration
    Type
    number | string
    Required
    required
    Description

    The duration of time to sleep:

    • Number of milliseconds
    • Time string compatible with the ms package, e.g. "30m", "3 hours", or "2.5d"
// Sleep for 30 minutes
await step.sleep("wait-with-string", "30m");
await step.sleep("wait-with-string-alt", "30 minutes");
await step.sleep("wait-with-ms", 30 * 60 * 1000);

step.sleep() must be called using await or some other Promise handler to ensure your function sleeps correctly.
