What is signal-exit?

The signal-exit package is used to capture and handle events that indicate Node.js process is about to exit. This includes handling of signals like SIGINT and SIGTERM, as well as normal process termination. It allows developers to register callbacks that can perform cleanup or other final actions before the process exits.

What are signal-exit's main functionalities?

Capture exit events

This feature allows you to capture any kind of exit, whether it's due to a signal or a normal exit. The callback function is called with the exit code and the signal that caused the exit, if applicable.

const onExit = require('signal-exit');

const removeExitHandler = onExit(function (code, signal) {
  console.log('Process is exiting with code:', code, 'and signal:', signal);
});

// Later, if you decide you do not want to handle the exit:
removeExitHandler();

Unregister exit handler

This feature allows you to unregister a previously registered exit handler. This is useful if the exit handling logic is no longer needed, or if you want to replace it with a different handler.

const onExit = require('signal-exit');

const removeExitHandler = onExit(function () {
  // cleanup logic here
});

// When you no longer need to handle exits:
removeExitHandler();
