Restart a node.js app from code level

Question

I\'ve an app which initially creates static config files (once) and after files were written I need to reinitialize/restart the application. Is there something

Answer 1

Found a working case to get node.js restarted from app itself:

Example:

// Optional part (if there's an running webserver which blocks a port required for next startup
try {
  APP.webserver.close(); // Express.js instance
  APP.logger("Webserver was halted", 'success');
} catch (e) {
  APP.logger("Cant't stop webserver:", 'error'); // No server started
  APP.logger(e, 'error');
}


// First I create an exec command which is executed before current process is killed
var cmd = "node " + APP.config.settings.ROOT_DIR + 'app.js';

// Then I look if there's already something ele killing the process  
if (APP.killed === undefined) {
  APP.killed = true;

  // Then I excute the command and kill the app if starting was successful
  var exec = require('child_process').exec;
  exec(cmd, function () {
    APP.logger('APPLICATION RESTARTED', 'success');
    process.kill();
  });
}

The only con I can see here is to loose outputs on console but if anything is logged into logfiles it's not a problem.
