random-cron

generate random cron task string in a humane way:

var rc = require('random-cron');
var job = rc.some('weekday').between(1, 3).generate();

/**
 * Then it will generate cron string like: * * * * 2
 */

Installation

npm install random-cron

Function

• some(time)

  add available rule to generate random cron string. Support time rule:

  • minute
  • hour
  • day
  • month
  • weekday

• between(start, end)

  set the temporal interval for the last time rule. The range must be within the cron time range definition:

  • minute: 0 - 59
  • hour: 0 - g
  • day: 0 - 31
  • month: 1 - 12
  • weekday: 0 - 6

• generate()

  generate cron task string. Be aware that random-cron doesn't validate the output and it could generate invalid cron string if you give an incorrect time range.

Example

You can chain these functions to create more complicated string.

var rc = require('random-cron');
var job = rc.some('weekday').between(1, 3)
            .some('hour').between(1, 12)
            .generate();

/**
 * Then it will generate cron string like: * 7 * * 2
 */
