Package Exports

cron

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cron) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

A NodeJS fork of jamespadolsey's cron.js.

Usage:

var cron = require('cron'), sys = require('sys');
new cron.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 cron = require('cron'), sys = require('sys');
new 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 {
        new cron.CronTime('invalid cron pattern', function() {
            sys.puts('this should not be printed');
        })
    } catch(ex) {
        sys.puts("cron pattern not valid");
    }
