Steps to reproduce

I'm trying to use kue for scheduled jobs on my Parse Server. For now I've modified my index.js file like so as stated in the several tutorials I found about Kue :

var express = require('express')
  , kue = require('due')
  , redis = require('redis');

var ParseServer = require('parse-server').ParseServer;

var databaseUri = process.env.DATABASE_URI || process.env.MONGOLAB_URI;

if (!databaseUri) {
  console.log('DATABASE_URI not specified, falling back to localhost.');
}

var api = new ParseServer({
  databaseURI: databaseUri || 'mongodb://localhost:27017/dev',
  cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js',
  appId: process.env.APP_ID || 'myAppId',
  masterKey: process.env.MASTER_KEY || '',
  serverURL: process.env.SERVER_URL
});
// Client-keys like the javascript key or the .NET key are not necessary with parse-server
// If you wish you require them, you can set them as options in the initialization above:
// javascriptKey, restAPIKey, dotNetKey, clientKey

// connect to REDIS
var client = redis.createClient(process.env.REDIS_URL);

var app = express();

// Serve the Parse API on the /parse URL prefix
var mountPath = process.env.PARSE_MOUNT || '/parse';
app.use(mountPath, api)
.use(kue.app); // wire up Kue (see /active for queue interface)


// Parse Server plays nicely with the rest of your web routes
app.get('/', function(req, res) {
  res.status(200).send('I dream of being a web site.');
});

var port = process.env.PORT || 1337;
app.listen(port, function() {
    console.log('parse-server-example running on port ' + port + '.');
});

I've found out that the app crashes at the line : .use(kue.app). Here is the error I get :

Starting process with command `node index.js`
parse-server-example running on port 22995.
/app/node_modules/parse-server/lib/index.js:298
        throw err;
        ^

Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6379
    at Object.exports._errnoException (util.js:890:11)
    at exports._exceptionWithHostPort (util.js:913:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1057:14)
Process exited with status 7
State changed from starting to crashed

I don't know why this is happening. And I need help on that as I'm not a Node/Express/Redis/Kue/Heroku ninja at all. :)

Why bother ?

I'm setting up a tutorial for anyone trying to get Kue up and running for Parse Server on Heroku. This could be useful according to #153. So any help could help me finish this for the community !

It seems that kue is not able to connect to Redis. Is it Redis installed in your server and the connection (127.0.0.1:6379) valid?

[gfosco]

Yeah this seems to be a pretty straightforward error, your Kue instance cannot connect to Redis.

I found out my mistake here. Thank you for your help.

Does anyone know of a working tutorial for this. I am having a few problems getting this up and running on my end

[christianpbrink]

@AmbroiseCollon Did you ever publish the tutorial on using Kue with Parse Server?

[AmbroiseCollon]

@rendragon83 @christianpbrink didn't have time to finish it. But I've detailed a bit my code in #1628. Hope you'll find this helpful.

Thanks!
