I need a Nodejs scheduler that allows for tasks at different intervals

Question

I am looking for a node job schedule that will allow me to schedule a number of tasks at different intervals  For instance     call function A every 30 seconds call function B every 60 seconds call function C every 7 days   I also want to be able to start and stop the process   So far  I have looked at    later - the syntax confuses me  also apparently you cant schedule tasks beyond a month agenda- seems the most promising  however I m confused about the database functionality timeplan - too simple  can t start and stop   I find the syntax of the latter confusing

I have written a small module to do just that, called timexe:

Its simple,small reliable code and has no dependencies
Resolution is in milliseconds and has high precision over time
Cron like, but not compatible (reversed order and other Improvements)
I works in the browser too

Install:

npm install timexe

use:

var timexe = require('timexe');
//Every 30 sec
var res1=timexe(”* * * * * /30”, function() console.log(“Its time again”)});

//Every minute
var res2=timexe(”* * * * *”,function() console.log(“a minute has passed”)});

//Every 7 days
var res3=timexe(”* y/7”,function() console.log(“its the 7th day”)});

//Every Wednesdays 
var res3=timexe(”* * w3”,function() console.log(“its Wednesdays”)});

// Stop "every 30 sec. timer"
timexe.remove(res1.id);

you can achieve start/stop functionality by removing/re-adding the entry directly in the timexe job array. But its not an express function.

I would recommend node-cron  It allows to run tasks using Cron patterns e g                 - runs every second    5            - runs every 5 seconds  10 20 30            - run at 10th  20th and 30th second of every minute  0            - runs every minute  0 0          - runs every hour  at 0 minutes and 0 seconds    But also more complex schedules e g    00 30 11     1-5  - Runs every weekday  Monday through Friday  at 11 30 00 AM  It does not run on Saturday or Sunday    Sample code  running job every 10 minutes    var cron   require  cron    var cronJob   cron job  0   10           function           perform operation e g  GET request http get   etc      console info  cron job completed         cronJob start      You can find more examples in node-cron wiki  More on cron configuration can be found on cron wiki  I ve been using that library in many projects and it does the job  I hope that will help

I ve used node-cron and agenda    node-cron is a very simple library  which provide very basic and easy to understand api like crontab  It doesn t need any config and just works   var cronJob   require  cron   CronJob  var myJob   new cronJob  00 30 11     1-5   function          myJob start      agenda is very powerful and fit for much more complex services  Think about ifttt  you have to run millions of tasks  agenda would be the best choice   Note  You need Mongodb to use Agenda  var Agenda   require  Agenda    var agenda   new Agenda  db    address   localhost 27017 agenda-example      agenda every    3            delete old users    agenda start
