Easily register tasks to perform when the current node process exits.
npm install on-exit
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.
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));
