I use express.js and 'cron' module for auto db updating, so I dont know where should I add my cron init code, so I added it to my 'bin/www' , but after server started it spams like every seconds(but I need every 2 minutes), but if I changed 2 on 5 , its never started. here is my cron update js:
var catalogUpdater = require('../utils/catalogUpdater');
var descriptionDownloader = require('../utils/descriptionDownloader');
var CronJob = require('cron').CronJob;
var job = new CronJob('* */2 * * * *', function(){
console.log('started');
},
function(){console.log('stop')},
true);
module.exports = job;
here is my ' bin/www ' code:
var app = require('../app');
var debug = require('debug')('shopnagby:server');
var http = require('http');
var config = require('../config');
var job = require('../cron/updateCron'); // include job updateCron to server startup;
/**
* Get port from environment and store in Express.
*/
var port = normalizePort(config.get("port"));
app.set('port', port);
/**
* Create HTTP server.
*/
var server = http.createServer(app);
/**
* Listen on provided port, on all network interfaces.
*/
server.listen(port);
server.on('error', onError);
server.on('listening', onListening);
.....
Where should I put my updateCron script?
You have incorrect cron syntax. Correct syntax have only 5 fields:
field allowed values
----- --------------
minute 0-59
hour 0-23
day of month 0-31
month 0-12 (or names, see below)
day of week 0-7 (0 or 7 is Sun, or use names)
To run in every two minutes:
var job = new CronJob('*/2 * * * *', function(){
console.log('started');
},
function(){console.log('stop')},
true);
