node.js - Restart current instance using NodeJS -

i'd restart application inside application using nodejs , npm.

it doesn't work child_process :

var exec = require('child_process').exec; exec('npm restart', function(error, stdout, stderr) {     console.log('stdout: ' + stdout);     console.log('stderr: ' + stderr);     if (error !== null) {         console.log('exec error: ' + error);     } }); 

if master process died, there no way reanimate him himself.

have @ nodemon restart script.
