Bun — Postel

Bun.serve is Fetch-native — verify with @postel/http's fetchWebhook today; a dedicated @postel/bun adapter is planned.

Bun.serve hands your fetch handler a Web Request, so the framework-agnostic @postel/http handler works directly:

import { fetchWebhook } from "@postel/http";
import { postel } from "./postel";

const handler = fetchWebhook(postel.inbound.vendor, {
  onVerified: async ({ event }) => {
    await handleOrder(event);
  },
});

Bun.serve({
  fetch(req) {
    if (new URL(req.url).pathname === "/webhooks/vendor") return handler(req);
    return new Response("not found", { status: 404 });
  },
});

The @postel/bun package name is reserved — a stub today. A future release adds Bun-specific ergonomics on top of @postel/http; until then, use @postel/http directly.
