ExpressWebJs Scheduler Typescript Version

The software utility cron also known as cron job is a time-based job scheduler in computer operating systems. Users that set up and maintain software environments use cron to schedule jobs to run periodically at fixed times, dates, or intervals. ExpressWebJs Scheduler makes that really easy to achieve.

Getting started

• First install expressweb-scheduler-ts

    npm install --save expressweb-scheduler-ts

• Import Scheduler

import { Schedule } from "expressweb-scheduler-ts";

• Schedule a command

Schedule.command("sendNewsletter").everySecond().run();

• You can also run a closure function using the call method

Schedule.call(() => {
  console.log("this is a closure that is been run every seconds");
})
  .everySecond()
  .run();

• You can also use the cron method:

Schedule.command("sendNewsletter").cron("* * * * * *").run();
