ctrlc-exit

Exit the process when Ctrl+C is pressed

Useful for CLI tools when default behavior to exit is disabled (e.g. raw mode is enabled).

Install

$ npm install ctrlc-exit

const ctrlcExit = require('ctrlc-exit');

ctrlcExit();

Using this prevents the process from exiting normally.

There are multiple ways you can handle this:

Call ctrlcExit.done() when you're done listening. It will then let the process exit normally.
Use process.stdin.unref() if you don't intend to use process.stdin afterwards. It will let the process exit normally.
Call process.exit() to exit the process directly.
