fine

"Fine" [fì-ne] - means "End" in Italian.
The point in time when an action, event, or phenomenon ceases or is completed; the conclusion.

About

Zero dependency and opinionated package that gracefully shutdown Node.js applications.

It provides extendability by taking an array of callbacks that will be executed serially to allow closing user-defined resources, eg: a database connection, drain streams, etc; before timeout exits the main process.

ESM

This package now exports both ESM and CommonJS. If, for some reason, you really really need only the CommonJS version refer to v1.4.0.

    promisify(server.close),
    // or you can just sto accepting new one and continue closing other callbacks
    server.close,

    async () => {
      // Throws will be NOOP-ed
      await db.disconnect();
