Drupal 7 integration with nodejs for realtime notificaiton

At the end of this blog you will be able to broadcast a real time notification to all loggedin user. As shown below

I assume you know
1. how to setup drupal on your local machine
2. how to use drush
3. npm installed, if not refer installing npm

Step 1.
Go to root of your drupal project and run following commands

drush dl nodejs  
drush en -y nodejs nodejs_config nodejs_notify nodejs_actions nodejs_subscribe

Here we are installing necessary modules.

Step 2.

Nodejs server required . To download run following commands

 git clone https://github.com/beejeebus/drupal-nodejs.git 

 cd  /var/www/drupal-nodejs

   npm install

  cp    nodejs.config.js.example nodejs.config.js

open the "nodejs.config.js" file in editor.

Step 3.

Open following url in browser.

 YOUR_VIRTUAL_HOST/admin/config/nodejs/js  

This will open configuration builder  UI. It will look like

Exact configruation which worked for me

 

 * This configuration file was built using the 'Node.js server configuration builder'.  
 * For a more fully commented example see the file nodejs.config.js.example in the root of this module  
 */  
 backendSettings = {  
  "scheme":"http",  
  "host":"localhost",  
  "port":9001,  
  "key":"/path/to/key/file",  
  "cert":"/path/to/cert/file",  
  "resource":"/socket.io",  
  "publishUrl":"publish",  
  "serviceKey":"murli800",  
  "backend":{  
  "port":80,  
  "host":"quora.api",  
  "messagePath":"/nodejs/message"},  
  "clientsCanWriteToChannels":false,  
  "clientsCanWriteToClients":false,  
  "extensions":"",  
  "debug":true,  
  "transports":["websocket",  
  "polling"],  
  "jsMinification":true,  
  "jsEtag":true,  
  "logLevel":1};

Copy the configuration and replace all content  in "nodejs.config.js" , which you opened in Step 2.

Step 4.

Run following commands

 cd /var/www/drupal-nodejs  
 node app.js  

This will start the server in foreground.

Now open following url to send broadcast message to all user.

 YOUR_VIRTUAL_HOST/admin/config/nodejs/nodejs_notify/broadcast  

This will open UI like

Now login with any user in other browser so that you can see notification .Submit the above form from the browser in which admin is logged in. If the setup is fine , then you will see a pop like

I hope this would help :)
