CRONY

Manage all your cron jobs in one file

Features

• Maintain one master crontab job.
• Jobs run via DENO, so you can run them under any programmatic conditions.
• Use ordinary crontab schedule syntax.

Getting Started

Create File

create main.ts file and import crony

import {Crony} from "https://deno.land/x/crony/mod.ts";


// Create a new instance of Crony
const crony = new Crony();

// Every job has a name
crony.add({
    name:'Task1',
    schedule : "* * * * *",
    enabled: true,
    debug:true,
    command: "ps -ax | grep deno | cut -d ' ' -f 1"
})

// Or with function

crony.add({
    name: "Task2",
    schedule : "*/2 * * * *",
    debug: true,
    command: async () => {
        const res =  await fetch('https://deno.land/').then(body => body.text())
        return {res}
    },
    enabled: true
})


await crony.run();

after that add the following line to your crontab:

* * * * * cd ~/your/project/path/ && deno run --allow-run --allow-net --allow-read --allow-write --unstable main.ts >> /dev/null 2>&1

Note: you might need to specify fully qualified deno path in order to run crontab. Also make sure that commands you running inside crontab is available

Available Options

Each job requires these configurations to run:

Key	Type	Description
