sindresorhus/loud-rejection

loud‑rejection is a tiny Node.js utility that globally watches for unhandled promise rejections, logs the error to stderr and forces the process to exit with a non‑zero code. It’s intended for top‑level scripts such as CLI tools, test runners, or server entry points where silent promise failures would be hard to spot, but not for reusable libraries. It works by installing an `unhandledRejection` listener (or via a simple `require('loud-rejection/register')`).
