A NodeJS fork of jamespadolsey's cron.js.


var cronJob = require('cron'), sys = require('sys');
cronJob('* * * * * *', function(){
    sys.puts('You will see this message every second');

Available Cron patterns:

Asterisk. E.g. *
Ranges. E.g. 1-3,5
Steps. E.g. */2

Read up on cron patterns here.

Another example

var cronJob = require('cron2'), sys = require('sys');

cronJob('00 30 11 * * 2-6', function(){ // Runs every weekday (Monday through Friday) // at 11:30:00 AM. It does not run on Saturday // or Sunday. });

How to check if a cron pattern is valid:

    try {
        cronJob('invalid cron pattern', function() {
            sys.puts('this should not be printed');
    } catch(ex) {
        sys.puts("cron pattern not valid");
