Testing Node.js Functionality with a “Hello World” App (Firstserv Guide)

If you're experiencing issues with your custom Node.js application, it’s useful to first confirm that the Node.js service itself is working correctly. You can do this by creating a simple “Hello World” application.

Important Notes

• Firstserv supports the Node.js service and environment only
• Troubleshooting your custom application, dependencies, or code falls outside our support scope
• If your application requires advanced configuration or production-level setup, we recommend using a VPS or dedicated environment

Step 1: Create a Node.js Application

1. Log in to your cPanel account
2. Navigate to the Software section
3. Click Setup Node.js App

Create the Test App

1. Click Create Application

2. Set the following:

   • Application Root: helloworld
   • Application URL: helloworld

3. Click Create

Step 2: Access Your Test Application

Once created, you should be able to visit your test application at:

https://yourdomain.com/helloworld

What This Test Confirms

• If the page loads successfully, the Node.js service is running correctly
• Any issues with your main application are likely related to:
  • Application code
  • Dependencies/modules
  • Configuration

Next Steps

If your “Hello World” test works but your main application does not:

• Review your application logs
• Verify installed dependencies
• Check environment variables and configuration

Summary

Creating a simple Node.js test app helps you quickly determine whether:

• ✅ The server and Node.js service are functioning as expected
• ❌ Issues are specific to your application

If you need help confirming your Node.js environment is running correctly, the Firstserv support team is happy to assist.
