Nodejs once every eight hours

Question

I am trying to impliment into my nodejs script a function to allow once per 8 hours a select command.

example:

!hug <--- would let bot respond with a hug but only once every 8 hours

I've been scouring online but cannot find what I need... I am trying to get it as simplified as possible.. (i.e without mongo... etc)

Answer 1

You can use node-schedule for this and for more versatility where you can configure days, hours and minutes and cancel on particular conditions being met this also gives you to use cron expressions as well.

var schedule = require("node-schedule");

var rule = new schedule.RecurrenceRule();
//Will run at 1am 9am and 5pm
rule.hour = [1, 9, 17];

var task = schedule.scheduleJob(rule, function(){
     //Do Stuff
     console.log("Scheduled Task Running...")
     /*
     if(condition met)
        task.cancel();
     */
});

Answer 2

You can use node-cron

var CronJob = require('cron').CronJob;
var job = new CronJob('00 30 11 * * 1-5', function() {
  /*
   * Runs every weekday (Monday through Friday)
   * at 11:30:00 AM. It does not run on Saturday
   * or Sunday.
   */
  }, function () {
    /* This function is executed when the job stops */
  },
  true, /* Start the job right now */
  timeZone /* Time zone of this job. */
);
