Running a NodeJS cron from cron-job.org

I am trying to run a NodeJS cron at a set interval using cron-job.org, but they don't have any documentation about how to actually run the script.

Basically the service visits a URL that you provide at a set interval, but I am specifically confused about what kind of code I can put on the endpoint (specifically what type of code will actually run). Can someone provide an example of what I would put at the endpoint URL?

cron-job.org only allows you to call an endpoint at a set time interval.

If you want to have some code run at a set interval without worrying about HTTP server, deploying, etc... Check out services like chunk.run

Here's an example code: https://chunk.run/c/scheduled-run-example

Then you can just select the trigger "Scheduled" like so:

scheduled trigger chunk run

You can do something really simple using either the HTTP module in Node.js or the popular Express module. Using express you can do something really simple like: 

var express = require('express');
var app = express();

app.get("/test", function(req, res, next){
    res.setHeader('Content-Type', 'application/json');
    res.send(JSON.stringify({ status: 'OK', timeStamp: new Date().toISOString() }));
});

console.log('Express listening.. on 3000');
app.listen(3000);

You can really run anything you like in the /test endpoint, though when it's being called from cron-job.org they'll probably stop if you keep throwing back 400 errors at them or the script takes really long to execute.

You'd call this using the url

http://yourdomain:3000/test

And of course you might well want to change the port number and path!
