cronjo v1.1.6

Introduction

Lets you create scheduled jobs. Unlike other packages, it uses the power of the cronti package. So you don't need to master crontime expressions to create scheduled jobs.

Unlike other packages that do similar work, it does not require mastery of crontime expressions. In this regard, other packages also have date input support. But you have to calculate and enter this date yourself. You don't need to do such a calculation in the cronjo package. Because it uses the power of the cronti package.

With the power of the cronti package, you can create scheduled jobs with scheduling/timing expressions used in daily life.

Install

Using npm:

npm i cronjo # Locale Install. For use in spesific project.
npm i -g cronjo # Global Install. For use in general projects.

Note: Add --save if you are using npm < 5.0.0

Documentation

The cronjo function can take the job function, options, or "HELPERS" in the first parameter, or take no value at all. If it is used with the job function, the crontime expression should be written in the second parameter. If used with options values, the next parameters are filled in accordance with the requirements in the cronti package. If used with "HELPERS" then no parameter input is needed. If no parameter values are sent, all created scheduled jobs are returned.

cronjo(<job(function)|options(object)|"HELPERS"(string)>, <crontime(string)|...args>)

job

It can be used when you want to use the crontime expression while creating a scheduled job. The job function is entered in the first parameter. A valid crontime expression is entered in the second parameter.

The id of the scheduled job is sent to the job function as a parameter.

Input

Output (object)

Example

const cronjo = require("cronjo")
cronjo((scheduleId) => { console.log("OK", scheduleId) }, "0 12 * * *")

options

4 features are offered. These are called method, job, name, and firstDayOfWeek.

options.method

Features brought by cronti package are discussed. The only difference is in the "HELPERS" method. This method returns the helper functions from the cronjo package.

options.method.onWeek

Used to create a scheduled job that will be triggered every day in the week of the entered date. Creates the scheduled job that will be triggered before the entered date based on the tick value.

A valid date value must be sent as a parameter. Any numeric value can be used for the tick value.

Input

Output (object)

}, "2022-05-26T09:30:00.000Z")

options.method.onIntervalTime

It is used to create a scheduled job based on the start and end date. According to the Step Parameter, the intervals between two dates are specified. The Step Parameter is used in days, hours, or minutes.

• If only the month(0..11) parameter is populated, the scheduled job is created for each day in that month.
• If only parameter weekDays(0..6) is populated, scheduled job will be created for this week day (Mon,Sl,Wed,Thur,cm,cm,Mon) every month.
• If only the month(0..11) and weekDays(0..6) parameters are populated, the scheduled job is created for the day of this week of this month.
