I'm using pm2 to running node application. I must save data before application will be closed. This code works fine in shell:

process.on('exit', function(){
    log.debug('exit');
});

process.on('SIGINT', function(){
    log.debug('SIGINT');
});

process.on('uncaughtException', function(){
    log.debug('uncaughtException');
});

When I'm stopping the application using "pm2 stop" the code doesn't work. I think that pm2 kills process.

SIGINT is generally triggered after a user-invoked shutdown (e.g. Ctrl+C). Assuming pm2 is triggering an abrupt shutdown then SIGINT won't be triggered.

Instead, you should listen for the termination signal SIGTERM which should cover both scenarios

process.on('SIGTERM', function() {
    // clean up
});
