Run your function on a schedule

Easily define your function with a cron schedule and Inngest will automatically invoke your function on that schedule.

Run code at a specific time

Using Inngest's step.sleepUntil to delay running code to an exact timestamp. Schedule any work based off user input.

Automatic retries

Failures happen. Inngest retries your functions automatically.

Schedule work in a few lines of code

→ Define a function using a cron schedule

Use when your code needs to run periodically.

1import { inngest } from "./client";
2
3// Define a function to run on a cron-schedule:
4inngest.createFunction(
5  { id: "send-weekly-digest-email" },
6  { cron: "TZ=America/New_York 0 9 * * MON " },
7  async () => {
8    // This function will run every Monday at 9am New York time
9  }
10);

→ Run at a specific timestamp defined in an event

Use when you needs to schedule something dynamically, like a reminder time set by a user.

1import { inngest } from "./client";
2
3// Define a function which sleeps until a given timestamp:
4inngest.createFunction(
5  { id: "post-slack-reminder" },
6  { event: "slack.reminder.scheduled" },
7  async ({ event, step }) => {
8    await step.sleepUntil(
9      "wait-for-reminder-time",
10      event.data.reminderTimestamp
11    );
12
13    await step.run("send-slack-notification", async () => {
14      // This will run after the given reminder timestamp
15    });
16  }
17);
