In our continuous efforts to simplify the installation process for Orangescrum, we’re constantly updating installation instructions for our users.
In this article, I will guide you how to install the Node.js for In-App Chat add-on on your Orangescrum server.
What is Node.js?
Why we chose Node.js?
Following are some of the important features that make Node.js the first choice of software architects.
Asynchronous and Event Driven ? All APIs of Node.js library are asynchronous, that is, non-blocking. It essentially means a Node.js based server never waits for an API to return data. The server moves to the next API after calling it and a notification mechanism of Events of Node.js helps the server to get a response from the previous API call.
Single Threaded but Highly Scalable ? Node.js uses a single threaded model with event looping. Event mechanism helps the server to respond in a non-blocking way and makes the server highly scalable as opposed to traditional servers which create limited threads to handle requests. Node.js uses a single threaded program and the same program can provide service to a much larger number of requests than traditional servers like Apache HTTP Server.
No Buffering ? Node.js applications never buffer any data. These applications simply output the data in chunks.
License ? Node.js is released under the MIT license.

There are 6 simple steps to install Node.js on your server. These are as follows:
- Download Node.js from here.
- Install Node.js and NPM
yum install npm node.js
yum –enablerepo=epel install npm node.js
yum install gcc-c++ make
yum install openssl-devel
- Install socket.io using NPM
npm install socket.io
- Install Forever
npm install forever -g
- Run the notification.js (given with the In-App chat) file forever using the “Forever”. (it should not stop)
- Upload the node js file and go to that path
Note: You can find the notification.js file in Orangescrum folder
- After following all the above steps, please copy and paste the “notification.js” file (given with the chat add-on) in the same directory where the node_modules is installed
- Run the below command to start node.js.
forever start notification.js
You must Disable firewalld/Selinux service by the command:
service firewalld stop / setenforce 0
Start the firewall service:
service firewalld start
Added the node port 3002 on firewall rules
firewall-cmd –permanent –add-port=3002/tcp
Reload the firewall service:
To list all Firewall rules
Now node server is ready. You can test by checking the below URL
If output is “Welcome to socket.io.” then node.js is working fine and you can use that URL in the constant.php as “NODE_HOST”
Note: you can find notification.js, node-js-installation-linux.pdf, node-js-installation-windows.pdf file in Orangescrum folder after installing the In-App chat.
