I am using node-schedule to schedule my tasks. Now I need to schedule a job everyday at 12am.
Below given is the code I am using,
var rule3 = schedule.scheduleJob('00 00 00 * * *', function(){
console.log('my test job!');
});
This is not working for me.
Any help appreciated. Thanks in advance.
You can use node-cron module simply.
var CronJob = require('cron').CronJob;
var job = new CronJob('00 00 12 * * 0-6', function() {
/*
* Runs every day
* at 12:00:00 AM.
*/
}, function () {
/* This function is executed when the job stops */
},
true, /* Start the job right now */
timeZone /* Time zone of this job. */
);
Read docs for more pattern.
For anyone who is stuck on this also check what time your app is operating in. Your app by default might be in Greenwich Mean Time which would definitely make you think your schedule is not working. Toss a console.log(Date.now()) in a convenient location and check. You might just have to adjust the time on your schedule by a couple hours.

I'm trying to run a Node task/function at a specific time each day (7am Eastern Time) regardless of Daylight Savings. I've tried cron-based packages, but cron doesn't seem to account for it. The server the app is running on is on GMT/UTC, so that that needs to be taken into consideration as well. Here is my current code:
const schedule = require('node-schedule');
...
const j = schedule.scheduleJob('0 12 * * *', function(){
bot.channels.get(getDefaultChannel().id).send("Hello! Your daily fact for today is", { embed: generateEmbed(getRandomFact()) });
});
This works fine, but since we just moved ahead an hour, the message appears at 8am instead of 7am.
This is a tricky one, I've played about with a couple of ways of doing this, I think the Cron library works the best (https://www.npmjs.com/package/cron). You can schedule a job to run at 7 am in the US/Eastern timezone.
"use strict";
var cron = require('cron');
var job1 = new cron.CronJob({
cronTime: '0 7 * * *',
onTick: function() {
bot.channels.get(getDefaultChannel().id).send("Hello! Your daily fact for today is", { embed: generateEmbed(getRandomFact()) });
},
start: true,
timeZone: 'US/Eastern'
});
I tried with node-schedule package
[https://www.npmjs.com/package/node-schedule][1]
var schedule = require('node-schedule');
var j = schedule.scheduleJob('42 * * * *', function(){
console.log('The answer to life, the universe, and everything!');
});
But if I schedule for 10 minutes and start the process it is processing after 10 minutes.
In my case, I need the process to be run for the first time and later it should run with scheduled time.
Is there any solution for this kind of issue?
Thanks in Advance..
There is a way to do it , just found it
let startTime = new Date(Date.now()) ;
var j = schedule.scheduleJob({ start: startTime, rule:'42 * * * *'},
function(){
console.log('The answer to life, the universe, and everything!');
});
Hope this helps
See this documentation of node-schedule
You can use codes from https://github.com/kelektiv/node-cron.
Then you can fire the crontab job at the second when you start nodejs program. After the crontab job will be run at certain interval.
This is an example to run the job immediately when creating the crontab work.
const CronJob = require('cron').CronJob;
const job = new CronJob({
cronTime: '0 */5 * * * *',
onTick: () => console.log(`Round at ${new Date()}`);
runOnInit: true
});
job.start();
In codes above, the "console.log" will be run when I start my program. Then it will run at every 5 minutes. For more usage, you can refer to the lib provided.
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)
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();
*/
});
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. */
);
I am running a cron job using the module node-cron for node js . My code is below.
var Job = new CronJob({
cronTime: '* * 01 * * *', //Execute at 1 am every day
onTick : function() {
co(function*() {
yield insertToDatabase(); //this is the function that does insert operation
}).catch(ex => {
console.log('error')
});
},
start : false,
timeZone: 'Asia/Kolkata'
});
I need to execute this only one time but this cronjob once starts runs multiple times due to which same data gets inserted to my database. I only need to run this job only one time. What should i do.
I know I am late to the party but I think that I have a solution. I hope this can help someone else in the future (Hi future!)
I encountered what I think to be the same issue as the asker, that is, the OnTick function executes multiple times after the scheduled time, this appeared to the author to be an endless loop. The asker expected this function to run only once at the scheduled time everyday (today, tomorrow, etc).
With that in mind the cause of this "issue" is simple. The cron job is scheduled to to exactly this. The cron time entered is * * 01 * * * which means the hour is 01 (aka 1:00am) but the minutes and seconds are *. This means any minute and any second where the hour is 01. So this will run from 1:00am up until 1:59am. It will run for each second of each minute until 2:00am. If the author had waited until 2:00am the "looping" would have ceased.
The solution is to set the seconds and minutes to anything that is not * (0 in my case worked).
I feel really silly for not having figured this out right away but here it is!
You can call Job.stop() from onTick:
onTick : function() {
Job.stop();
co(function*() {
yield insertToDatabase();
}).catch(ex => {
console.log('error');
});
}
In my case, i changed my code from this :
var job = new CronJob('*/59 * * * *', onTick, onComplete, true, 'Asia/Kolkata'); // onTick and onComplete is a function, which i'm not showing here
job.start();
To this :
var job = new CronJob('*/59 * * * *', onTick, onComplete, false, 'Asia/Kolkata'); // onTick and onComplete is a function, which i'm not showing here
job.start();
Thanks
I try to develop a little browser game based on NodeJS and Angular 4.
I have an API server running on NodeJS which is connected to a MongoDB and a second server running Angular 4.
I want to execute recurring standard functions (like every 15 minutes) in the background.
Do I need a third server which runs that functions? Or can I run that functions independently on my API server - no matter which route is open?
You might want to have a look to this library node-cron. You can set it up to work with your services. You will need to initialise the job right after your sever is initialised. An example:
var CronJob = require('cron').CronJob;
var job = new CronJob({
cronTime: '00 30 11 * * 1-5',
onTick: function() {
/*
* Runs every weekday (Monday through Friday)
* at 11:30:00 AM. It does not run on Saturday
* or Sunday.
*/
},
start: false,
timeZone: 'America/Los_Angeles'
});
job.start();
You can use setTimeout() and setInterval() in Node just like in the browser:
setInterval(() => {
// this runs every 15 minutes
}, 15 * 60 * 1000);
