socketcluster-server + sc-broker-cluster

[fas3r]

Hello,

Could it be possible to get some information or guidance on how to implement the sc-broker-cluster with the socketcluster-server ?

When I set the brokerEngine to 'sc-broker-cluster' in the options I'm getting the following error :

/tmp/scc/app/node_modules/socketcluster-server/scserver.js:101
  this.brokerEngine.once('ready', function () {
                    ^
TypeError: this.brokerEngine.once is not a function

Thanks !

Hi,

I also get this error. Looking /scserver.js, it seems that the server does not try to require the broker from the string. Instead it seems to expect an instance to be handed over.

I tried passing new require('sc-broker-cluster'').Client(), which gave me a new error:

TypeError: Cannot read property 'brokers' of undefined
    at new module.exports.Client (/home/user/NodeJS/project/node_modules/sc-broker-cluster/index.js:438:25)

I do appreciate that the developers made a ready to go framework which handles this issue for you, but what I like about NodeJS is the flexibility of it`s modules. If it is possible, I do want to manage the processes on my own, even though this will lead to more work.

I also looked into the socketcluster source code, but it was a bit hard to understand the whole process. Heck, I don't think I even found where multiple brokers are created. Once I have more time, I might give it another go, but for now, a minimal tutorial would be nice.

Look at the scc-cluster-broker

Hi @matth-c3 , do you mean sc-broker-cluster?

I did, but I'm still not sure how to properly do it.

From my understanding, you run the sc-cluster-broker.Server on a separate process and then pass the sc-cluster-broker.Client to the socketcluster-server, but I don''t quite understand the details behind it yet.
