Write functions, send events.

Create and deploy background jobs or scheduled functions right in your existing JavaScript or TypeScript codebase.

Works with:

Try the new SDK →

myGreatFunction.ts

1import { inngest } from "./client";
2import { DemoEventTrigger } from "./types"
3
4export default inngest.createFunction<DemoEventTrigger>(
5  { name: "My Great Function" },
6  { event: "demo/event.trigger" },
7  async ({ event }) => {
8    return { message: "success" }
9  }
10)

api/someEndpoint.ts

1import { Inngest } from "inngest"
2import { Events } from "../../__generated__/inngest"
3const inngest = new Inngest<Events>({ name: "My App" })
4await inngest.send({
5  name: "demo/event.name",
6  data: { something: req.body.something }
7})

Simple, yet powerful

inngest/myGreatFunction.ts

1import { inngest } from "./client";
2import { DemoEventTrigger } from "./types"
3
4export default inngest.createFunction<DemoEventTrigger>(
5  { name: "My Great Function" },
6  { event: "demo/event.trigger" },
7  async ({ event }) => {
8    return { message: "success" }
9  }
10)

Run your code in response to events

Easily define functions that run in response to events. Background jobs, scheduled tasks, webhooks are all made easy with Inngest's SDK.

Trigger jobs with events from anywhere

Send events with our SDK to trigger background jobs and move longer running code out of the critical path of an API request.

inngest/scheduledTask.ts

1import { inngest } from "./client";
2
3export default inngest.createFunction(
4  { name: "A scheduled function" },
5  { cron: "0 9 * * MON" }, // any cron expression
6  async () => {
7    // Do work regulary at 9AM monday...
8    return { message: "success" };
9  }
10)

Schedule jobs easily

Run your code on a schedule using basic cron expressions. Cron jobs made simple with observability & logs.

1import { Inngest } from "inngest"
2import { serve } from "inngest/next"
3import { Events } from "../../__generated__/inngest"
4
5import { myGreatFunction } from "../../myGreatFunction"
6import { scheduledTask } from "../../scheduledTask"
7
8const inngest = new Inngest<Events>({ name: "My App" })
9
10export default serve(inngest, [
11  myGreatFunction,
12  scheduledTask
13])

Deploy to your existing setup

Inngest can remotely run your background tasks via secure HTTP handler. You keep your existing deployment workflow and we'll call your code where it is.
