Getting started

Install Inngest:

npm install inngest  # or yarn install inngest

Writing functions: Write serverless functions and background jobs right in your own code:

import { createFunction } from "inngest";

export default createFunction(
  "Send welcome email",
  "app/user.created", // Subscribe to the `app/user.created` event.
  ({ event }) => {
    sendEmailTo(event.data.id, "Welcome!");
  }
);

Functions listen to events which can be triggered by API calls, webhooks, integrations, or external services. When a matching event is received, the serverless function runs automatically, with built in retries.

Triggering functions by events: Send events to trigger functions automatically.

// Send events
import { Inngest } from "inngest";
const inngest = new Inngest({ name: "My App" });

// This will run the function above automatically, in the background
inngest.send("app/user.created", { data: { id: 123 } });

Events trigger any number of functions automatically, in parallel, in the background.

Features

• Fully serverless: Run background jobs, scheduled functions, and build event-driven systems without any servers, state, or setup
• Deploy anywhere: works with NextJS, Netlify, Vercel, Redwood, Express, Cloudflare, and Lambda
• Use your existing code: write functions within your current project, zero learning required
• A complete platform: complex functionality built in, such as event replay, canary deploys, version management and git integration
• Fully typed: Event schemas, versioning, and governance out of the box
• Observable: A full UI for managing and inspecting your functions
• Any language: Use our CLI to write functions using any language
