Answer 1

Here is:

var CronJob = require('cron').CronJob;

var job = new CronJob('00 00 00 * * *', function() {
  /*
   * Runs every day
   * at 00:00:00 AM. 
   */
   // DO SOMETHING
  }, function () {
    /* This function is executed when the job stops */
  },
  true /* Start the job right now */
);

})

You don't need to set all the fields. Set just first three and it'll take care of running every day at midnight
0 0 0 * * *

Answer 4

You can try this format too.

var CronJob=require('cron').CronJob;
var cronJob1 = new CronJob({

    cronTime: '00 00 00 * * * ',
    onTick: function () {
    //Your code that is to be executed on every midnight
    },
    start: true,
    runOnInit: false
});

To understanding something more about cronTime, See the following codes:

cronTime: '00 */3 * * * * ' => Executes in every 3 seconds.

cronTime: '* */1 * * * * ' => MEANING LESS. Executes every one second.

cronTime: '00 */1 * * * * ' => Executes every 1 minute.

cronTime: '00 30 11 * * 0-5 ' => Runs every weekday (Monday to Friday) @ 11.30 AM

cronTime: '00 56 17 * * * ' => Will execute on every 5:56 PM

Answer 5

0 0 * * *

This pattern will run CronJob job daily at 00:00
