Automate method call in NodeJS API

  • 772

I have developed a REST API in NodeJS and I need to automate the call to a method that retrieves the information from another API (a third party) every minute to insert it into my back-end .

My OS is Centos 6.9. I have read in some posts that it is possible to use cron to automate tasks, but I don't know if it is possible to carry out this task from NodeJS in the back-end itself .

Is there a way to do it from NodeJS ?

Thanks greetings

nodejs

    Better than using setIntervalis to create a cron.

    Example

    const  { CronJob } = require('cron');

// significa cada minuto
new CronJob('* * * * * *', function() {
  // llamar a método que consume el API
});

    For this example I have used the cron package . You can see about the cron syntax at this link .

  2. If you have a function let's say helloWorld() and you want to automate its call, I think you could use this way of doing it:

    helloWorld();
setInterval(helloWorld, 30000);

    What this would do is while you have the app up on the server, every 30000 ms it will make a call to the function that you pass to it as a parameter.
