How to view the output of the console.log function in Node.JS applications that are deployed though cPanel's Application Manager

Introduction

 

You can use the following information when deploying a Node.JS application via cPanel's Application Manager to view the output of console.log that you've added to your application code.

 

Procedure

 

The mod_passenger module that cPanel makes use of will publish the output from console.log to the Apache error log. In order to view your console.log output, you'll need to make sure that your application is configured properly so that mod_passenger is actually executing your application code. We have a blog post here about setting up a test Node.JS application:

https://blog.cpanel.com/how-to-host-a-node-js-application-with-cpanel/

 

Once you are confident that your application is setup properly, deployed, and your code has a console.log call, all you would have to do is tail the Apache log with the following command via SSH as the root user:

tail -fn0 /etc/apache2/logs/error_log

 

Then, visit the domain that your Node.JS application is setup on to make mod_passenger execute your code and print to the Apache log.
