I need to schedule a function in a future

Question

I want to schedule a function in a future. This is my code:

var timeout = setTimeout(function() {
                function();
                console.log("UNO");
            }, 5000);

But I don't like this solution, so Anyone know some method in nodejs that I use to schedule a function in the future?

Why put the function in another function? Can't you just add the console.log to function() itself?, that would make it a nicer solution. — Gilles Lesire, Aug 22 '17 at 14:10
`Because if I restart server, the timeout is detroied!` Please update your question with important information such as this that could explain exactly what you are trying to achieve. — Nope, Aug 22 '17 at 14:12
No need to offload the function, but you either need the timer to run in another place (ie. redis queue) or use `setTimeout` and check the current time to see if the function should run or not. — Robert Rossmann, Aug 22 '17 at 14:13

There is this: https://www.npmjs.com/package/node-schedule

Also, you could set interval of 1 second (or millisecond or hour or whatever depending on precision you need) and inside of it check current time. If time is right, you trigger function.

Use can use node-schedule package

var scheduler = require('node-schedule');

var date = new Date(2018, 1, 1, 0, 0, 0);

var newYearJob = scheduler.scheduleJob(date, function() {
 console.log("Happy new year");
});

In case not needed

newYearJob.cancel();

You can use: https://www.npmjs.com/package/agenda

With this package the scheduler will still work after system or script restart thanks to persitant storage (MongoDB, Redis, ...)
