Node.js is an open source server environment that runs on various platforms (Windows, Linux, Unix, Mac OS X, etc.) and uses JavaScript on the server.
Let’s see how to install Node.js on web applications using the end user interface.
Note: If your Node.js is disabled then you won’t see the Node.js Selector icon.
End User interface helps end users to setup and manage Node.js for their web applications.
Hover to cPanel → Software Section → Select Node.js Version.
The Web Applications page will be displayed.
You will see several columns in the list. Let’s understand the use of each column.
- App URI: This column comprises of application URI along with the domain.
- App Root Directory: It comprises of application root directory related to user’s home.
- Mode: The mode can be either production or development.
- Status (started/stopped): It showcases the status of an application, if it’s running or not as well as the version of application.
- Actions: It helps to start, restart, stop, edit, and remove a particular application.

Application Error Log
After updating to alt-mod-passenger version 5.3.7-3, we have also started offering support for the PassengerAppLogFile directive.
Syntax: PassengerAppLogFile path
Default: PassengerAppLogFile path-to-passenger-log-file
Context: virtual host, htaccess
Passenger log messages are all written to the Passenger log file by default. The app specific messages get logged to a different file in addition with this option. The alt-mod-passenger allows you to use it in the context of a virtual host or in the htaccess file.
That’s it! In this way you can setup Node.js for web applications using end user interface.
