如何立即执行节点计划作业并每30分钟重复一次

Question

I have written a nodejs program, and want to schedule it using node-schedule npm, recurring every 30 mins. I have scheduled it using

var nodeSchedule = require('node-schedule');
nodeSchedule.scheduleJob('* /30 * * * *',require('./devModules.js').runDev);

Instead of executing immediately it is going for a sleep of 30 mins and then executing every 30 mins. How do I schedule it immediately and reoccur after every 30 mins?

Please help.

Answer 1

I think node-scheduler does not support this and things like this can be done with setInterval but to use it with corn use "corn" module:- Cron npm

 var cronJob = require('cron').CronJob; var myJob = new cronJob('0 */10 * * * *', function(){ console.log(new Date().toLocaleString()); },function(){ },true); // true value will start it once you start cron job
