OnComplete () not called in node cron

Hi I am trying to check node-cron

but I cannot get the desired answer in one case.

I need to initiate the cron request again when the current cron exits. So, I need onComplete()

to call, but I can't get the callback.

My code snippet:

CronWrapper.prototype.pushNotificationCron = function() {
    // change console to winston in real implementation.
    console.log('Creating job');
    var jobPattern = '*/10 * * * * *';
    var job = new CronJob(jobPattern, onJobStarted, onJobCompleted, false);
    console.log('Starting job');
    job.start();
};

var onJobStarted = function(){
    var date = new Date();
    console.log('Cron started on \t' + date);
    return;
};

var onJobCompleted = function(){
    winston.info('Job completed:');
};

      

Output:

Cron started on     Tue Dec 16 2014 12:59:40 GMT+0530 (IST)
Cron started on     Tue Dec 16 2014 12:59:50 GMT+0530 (IST)
Cron started on     Tue Dec 16 2014 13:00:00 GMT+0530 (IST)

      

Please indicate what mistake I am making.

Lib info:

"cron": "1.0.5"

After more detailed documentation, I found that I was missing the stop () call.

As stated in the documentation

onComplete - [OPTIONAL] - a function that is triggered when the task is completed , when it is stopped .

So now I manually call stop()

on completion and get the callback. So now my code looks like this:



CronWrapper.prototype.pushNotificationCron = function() {
    // change console to winston in real implementation.
    console.log('Creating job');
    var jobPattern = '*/10 * * * * *';
    var job = new CronJob(jobPattern, function(){
        var date = new Date();
        console.log('Cron started on \t' + date);
        job.stop();
    }, onJobCompleted, false);
    console.log('Starting job');
    job.start();
};

// var onJobStarted = function(){
//  var date = new Date();
//  console.log('Cron started on \t' + date);

// };

var onJobCompleted = function(){
    winston.info('Job completed:');
};

      

Output

Cron started on     Tue Dec 16 2014 13:13:30 GMT+0530 (IST)
info: Job completed:
