Access socket.io, client and server-side. As-well as redis database.

[Stackoverload]

Hello! I haven't seen anywhere talking about accessing socket.io via the client-side, as-well as listening to the client-side. I've used socket.io before, but I don't know if it's recommended that I just start a new instance of socket.io, or if there's a global variable of some sort I can access. On top of that, I was wondering the same for Redis database. I don't want to just create another instance/connection to the database if there's a global variable. Could someone enlighten me on this?

From the client side, the instantiated socket.io library can be accessed via the global variable socket.

On the server side, you can access the primary database through our abstraction layer:

var db = module.parent.require('../database');

Thank you so much!

Also: What about socket.io server-side? Is there a global variable for socket io? would it be var io = module.parent.require('../socket');?

Yes, except you'll want to load the socket.io folder (or the index.js file inside it).

Awesome. Thanks!

@julian Last thing. Should I just be calling a new instance of socket.io, and have it listening to port 80? Or is there a way I can access the instance of socket.io that's already running (in the backend) and just make a room/namespace?

You don't need to create a new instance just use the one exposed by socket.io/index.js

var sockets = require('./socket.io');

sockets.server.in('someRoom').emit('myEvent', {foo:'bar'});

I'm getting 'server' as undefined ( TypeError: Cannot call method 'in' of undefined_, using the following code.

(function() {
  'use strict';

  var winston = module.parent.require('winston'),
      plugins = module.parent.require('./plugins'),
      fs = require('fs'),
      path = require('path'),
      util = require('util'),
	  sockets = require('../socket.io'),
      app;
	 
  var Plugin = {
    staticAppLoad: function(params, callback) {
      winston.verbose("nodebb-plugin-market - staticAppLoad called");

      app = params.app;
      var router = params.router;
      
      var renderCustomPage = function (req, res) {
        res.render('products.tpl', {someInjectedData: "Longer dPlugin Title"});
		sockets.server.in('products').emit('TEST!');
	}
      router.get('/products', params.middleware.buildHeader, renderCustomPage);
      
      if (typeof callback === 'function') {
        callback();
      }
    }, //staticAppLoad

    
  };
  module.exports = Plugin;
})();

I think your require is wrong, should be module.parent.require('./socket.io'),

@yariplus Oh yes... Thank you haha
