Setting up quickblox with node

In this post I am going to set a node server to use Quickblox.

brew uninstall node
npm install -g express
Starting from express 4.00 you also need to install express generator as mentioned here. npm install -g express-generator
Generate new project: express chat
Install node modules: cd chat/ && npm install
Git-ignore node_modules directory
Start server: DEBUG=chat:* npm start
Check if its working localhost:3000
Install http status codes: npm install http-status-codes --save

Modify routes/index.js to return json instead of rendering index.html:

router.get('/', function (req, res, next) {
    res.status(HttpStatus.OK).json({title: 'Express'});
});

Restart server and test.
Install quickblox: npm install quickblox --save

Modify routes/index.js to initialize quickblox:

var QB = require('quickblox');
    
// initalise the environmenet with my application id, authentication key and authentication secret
QB.init(<CLIENTID>, <KEY>, <SECRET>);
    
// create an user session
var params = {login: 'system', password: 'welcome123'};
QB.createSession(params, function (err, result) {
    if (err) {
        console.log('Something went wrong: ' + err);
    } else {
        console.log('Session created with id ' + result.id);
    }
});
    
/* GET home page. */
router.get('/', function (req, res, next) {
    // list the users currently enrolled
    QB.users.listUsers(function (err, result) {
        for (var i = 0; i < result.items.length; i++) {
            console.log('User ' + result.items[i].user.login + ' is registered');
        }
    });
    res.status(HttpStatus.OK).json({title: 'Express'});
});

Restart and test if users are getting printed.

Shift the QB initialisation code to app.js and make QB a global var as mentioned here, because we have to use QB in multiple routes.

//Initialize quickblox
QB = require('quickblox');
    
// initalise the environmenet with my application id, authentication key and authentication secret
QB.init(31620, 'HGKzgragj54ktge', 'YeQ-bXJ7asULOU-');
    
// create an user session
var params = {login: 'system', password: 'welcome123'};
QB.createSession(params, function (err, result) {
    if (err) {
        console.log('Something went wrong: ' + err);
    } else {
        console.log('Session created with id ' + result.id);
    }
});

Restart and test if users are getting printed.
