#serverless #typescript #api #webdev

Inngest is a serverless event-driven platform for building reliable background jobs, workflows, and scheduled tasks without managing queues.

Define Functions

import { Inngest } from "inngest";

const inngest = new Inngest({ id: "my-app" });

export const processOrder = inngest.createFunction(
  { id: "process-order", retries: 3 },
  { event: "order/created" },
  async ({ event, step }) => {
    const payment = await step.run("charge-payment", async () => {
      return stripe.charges.create({ amount: event.data.amount });
    });

    await step.run("send-confirmation", async () => {
      return sendEmail(event.data.email, { orderId: event.data.id });
    });

    await step.sleep("wait-for-delivery", "3 days");

    await step.run("send-review-request", async () => {
      return sendEmail(event.data.email, { template: "review-request" });
    });

    return { success: true, paymentId: payment.id };
  }
);

Send Events

await inngest.send({ name: "order/created", data: { id: "123", email: "user@example.com", amount: 4999 } });

Scheduled (Cron)

export const dailyReport = inngest.createFunction(
  { id: "daily-report" },
  { cron: "0 9 * * *" },
  async ({ step }) => {
    const stats = await step.run("get-stats", () => getStats());
    await step.run("send-report", () => sendSlack(stats));
  }
);
