Send a push notification from Node.js

Setup (once, under a minute)

Install the Webhooky app (Android / iOS) – your endpoint URL is ready the moment it opens, no account needed.

The one-liner

await fetch("https://api.webhooky.app/YOUR_KEY", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ title: "✅ Deploy done", message: "v2.4.1 is live" }),
});

The catch-block pattern

async function notify(title, message, sound = "notification_1") {
  try {
    await fetch("https://api.webhooky.app/YOUR_KEY", {
      method: "POST",
      headers: { "Content-Type": "application/json" },
      body: JSON.stringify({ title, message, sound }),
    });
  } catch {} // never let the alert break the job
}

try {
  await chargeCustomer(order);
  await notify("💶 Payment received", `Order ${order.id} · €${order.total}`, "cash_register");
} catch (err) {
  await notify("🚨 Payment FAILED", String(err).slice(0, 500), "error_1");
  throw err;
}

Catch crashes process-wide

process.on("uncaughtException", async (err) => {
  await notify("🚨 Process crashed", String(err).slice(0, 500), "error_1");
  process.exit(1);
});

The same idea works in an express error middleware or a PM2 restart hook – and of course in Firebase Cloud Functions and Supabase Edge Functions.

All fields

title, message, sound (one of 40 ids like cash_register or error_1) and vibrate – everything optional, everything per message. Details in the API docs; the Python version of this guide is here.
