Random Cron Generator
This package provides tools to generate random cron expressions based on configurable parameters and calculate the next run time for any given cron expression. It uses cron-validate
to ensure generated cron expressions are valid and cron-parser
integrated with luxon
for calculating run times.
Features
- Generate random cron expressions with configurable settings.
- Validate cron expressions for correctness.
- Calculate the next run time of a cron expression.
- Optional logging of next run times during cron generation.
Installation
Install the package with npm:
npm install random-cron-generator
Usage
Importing the module
import { RandomCronGenerator, generateRandomCron, getNextRunTime } from 'random-cron-generator';
Generating a Random Cron Expression
// Generate a cron expression with default settings:
const cronExpression = generateRandomCron();
console.log(cronExpression); // Outputs a valid cron string (e.g. '0 0 * * *')
// Generate a cron expression with custom settings:
const customCronExpression = generateRandomCron({
randomConfig: {
minute: { min: 0, max: 59 }, // range of minutes
hour: true, // random hour. If false, it will be * (default)
dayOfMonth: '*/7', // string cron expression
month: 5, // specific month
dayOfWeek: undefined // * (default)
},
log: true // log the next run time
}
);
console.log(customCronExpression); // Outputs a valid cron string and logs the next run time (e.g. '33 * 1 10 *')
