on-exit

Easily register tasks to perform when the current node process exits.

Install

npm install on-exit

Usage

Call onExit one or more times to add process cleanup tasks:

var onExit = require('on-exit');
 
onExit(function() {
    console.log('Closing db connections...');
    db.close();
});
 
onExit(function() {
    console.log('Performing other cleanup...');
    app.cleanup();
});

When the process exits handlers will be run in the order that they were added.

Debug logs

You can set a logging function if you would like to log kill signals and exit events:

var onExit = require('on-exit').logger(function(msg) {
    myCustomLogger.log(msg);
});
 
// Or to console.log
onExit.logger(console.log.bind(console));
