signal-exit
Advanced tools
When you want to fire an event no matter how a process exits:
process.exit(code) called.process.kill(pid, sig) called.Use signal-exit.
var onExit = require('signal-exit')
onExit(function (code, signal) {
console.log('process exited!')
})
var remove = onExit(function (code, signal) {}, options)
The return value of the function is a function that will remove the handler.
Note that the function only fires for signals if the signal would cause the process to exit. That is, there are no other listeners, and it is a fatal signal.
alwaysLast: Run this handler after any other signal or exit
handlers. This causes process.emit to be monkeypatched.The exit-hook package provides similar functionality to signal-exit, allowing developers to register callbacks that are executed when the process exits. It also captures uncaught exceptions and unhandled promise rejections. Compared to signal-exit, exit-hook may offer a simpler API but might not handle all the edge cases that signal-exit does.
async-exit-hook is another package that allows you to run asynchronous code when the process exits. It is similar to signal-exit but focuses on supporting asynchronous operations during the exit handling. This can be particularly useful for ensuring that database connections are closed or files are written before the process terminates.
The death package (also known as DEATH on npm) is a simple utility to make handling UNIX signals and uncaught exceptions in Node.js easier. It provides a straightforward way to clean up after your script without much fuss. Compared to signal-exit, death has a more focused scope and does not handle normal process termination.
