node-reel-cron will use node-cron as default adapter. but you can pass your own adapter and return your own object.

const Reel = require('node-reel-cron').Reel;

const reel = new Reel({
    adapter : (object) => {
    	// use your cron library or custom cron logic
    	// below are the available properties
    	let expression = object.expression;
    	let callback = object.callback;
    	let timezone = object.timezone;
    	return mycron.schedule(expression, callback);

// use it as follows
reel.command('npm run foo').hourly().run();

Monitor the Scheduled Executions

If you want to keep an eye on every execution and make sure they succeed or fail, or even if they execute at all, or make a report of each, you can:

reel().command('npm run clean_trash', (error) => {
    if (error) {
	// Handle the error
    } else {
	// Report the success


issues, pull request and feedback are welcome ! Happy Scheduling !!
