Start and stop MERN app at a particular time

Does anyone have experience of how to start and stop a MERN app cleanly in a production environment at a particular time, say start at 9 am and stop at 5pm? The application is hosted with a client-server part in a virtual environment.S TIA.

Solution

  • You can use a cron job. When the cron job is called you can kill the application or restart it.

    const cron = require('cron')
const nrc = require('node-run-cmd')

cron.schedule('* * 9 * *', () => {
  nrc.run('npm start')
});

cron.schedule('* * 17 * *', () => {
  nrc.run('pkill -f node')
});

    If you don't want to kill all the node apps, get the pid first and use the appropriate pkill command
