The nodejs command is:

require('child_process').exec('sudo /sbin/shutdown -r now', function (msg) { console.log(msg) });

To avoid running nodejs as su you must give permission to run this command. Give permissions by creating a file under the /etc/sudoers.d/ directory, e.g.

$ sudo nano /etc/sudoers.d/mysudoersfile

Add the following lines and change pi in the below snippet to the user nodejs will be running as:

pi ALL=/sbin/shutdown
pi ALL=NOPASSWD: /sbin/shutdown

This technique can also be applied to other commands. For example if you want to allow the user (in turn nodejs) to restart networking then add the following to your sudoers file.

pi ALL=/etc/init.d/networking
pi ALL=NOPASSWD: /etc/init.d/networking

I use the Paules reply and the reboot npm package docs, and now its working as expected.

Permissions (Linux only)

If you are to run node process under non-superuser, be sure to give node permissions to reboot the system:

sudo setcap CAP_SYS_BOOT=+ep usr/local/bin/node

thanks for so far. I got a solution thats working with that now. only it has no response that the command has been executed. For the rest it's working.

code:

console.log('loaded.....');
var exec = require('child_process').exec;

function execute(command, callback){
    exec(command, function(error, stdout, stderr){ callback(stdout); });
}



execute('shutdown -r now', function(callback){
    console.log(callback);
});

You should use child_process and a command like sudo /sbin/reboot. Also you need to configure sudo to allow node.js user run /sbin/reboot w/o a password prompt. see /etc/sudoers.
