@kbn/cleanup-before-exit

Utilities for registering asynchronous cleanup tasks that should run before a Node.js process exits.

Usage

import { cleanupBeforeExit } from '@kbn/cleanup-before-exit';

cleanupBeforeExit(
  async () => {
    await closeServices();
  },
  { blockExit: true, timeout: 10_000 }
);

Options

Option	Default	Description
`blockExit`	`false`	When `true`, overrides `process.exit` so the process waits for the handler to settle.
`timeout`	`5000`	Milliseconds to wait before the handler is considered timed out; the timeout error is logged and ignored.

Handlers are guaranteed to only run once, all run in parallel, and any rejections are logged via OpenTelemetry diag.
