Last call metaphor

Finish in-flight work, then shut down — like closing time at a bar

📶

Signal-aware

SIGTERM, SIGINT, SIGHUP — built for Docker, Kubernetes, and PM2

🌊

Phased shutdown

pre → drain → cleanup → post with priorities and dependencies

🌐

HTTP drain

withHttpServer() stops accepting connections and drains in-flight requests

📊

Observable

Lifecycle events, metrics hooks, and optional verbose test logging

✅

Verified

Full line/function coverage, integration tests via child processes, verification matrix enforced in CI

Quick example

import { createLastcall } from 'lastcall';

const lastcall = createLastcall();

lastcall.withHttpServer(server);
lastcall.register(
  'database',
  async () => {
    await db.disconnect();
  },
  { critical: true, phase: 'cleanup' },
);

Send SIGTERM — lastcall runs your handlers in order and exits.
