How to use the async-exit-hook.unhandledRejectionHandler function in async-exit-hook
To help you get started, we’ve selected a few async-exit-hook examples, based on popular ways it is used in public projects.
Secure your code as it's written. Use Snyk Code to scan source code in minutes - no build needed - and fix issues immediately.

Run some code when the process exits (supports async hooks and pm2 clustering)
