  4. Scroll down to the "Web Options" section and select the "Passenger (Ruby/NodeJS/Python/Perl)" option.
  5. In the "Web Options" section, you will find a field labeled "Application Mode." Select "Node.js" from the dropdown menu.
  6. Scroll down further and locate the "Passenger Enabled" option. Enable it by clicking on the checkbox.
  7. Save the changes and return to the main panel.
  8. Now, connect to your DreamHost server using SSH or a similar tool.
  9. Navigate to the directory where you want to host your Node.js application. Typically, this would be the public or www directory of your domain/subdomain.
  10. Transfer or upload your Node.js application files to this directory. This can be done using FTP or SCP.
  11. Make sure that your main Node.js file is named app.js or index.js as this is the default file that DreamHost looks for. If you are using a different file name, you may need to modify the configuration.
  12. Next, create a passenger_wsgi.js file in the same directory. This file will serve as the entry point for passenger.
  13. In the passenger_wsgi.js file, add the following code:
 1

const spawn = require('child_process').spawn;
const app = spawn('node', ['app.js']); // Replace 'app.js' with your actual main file name

app.stdout.on('data', (data) => {
    console.log(`stdout: ${data}`);
});

app.stderr.on('data', (data) => {
    console.log(`stderr: ${data}`);
});

app.on('close', (code) => {
    console.log(`child process exited with code ${code}`);
});


  1. Save the passenger_wsgi.js file.
  2. Finally, restart your domain/subdomain in the DreamHost panel. This will activate the changes and start your Node.js application.


Your Node.js application should now be published and accessible via your domain/subdomain on DreamHost.

What is the process to secure a NodeJS app on DreamHost?

To secure a NodeJS app on DreamHost, you can follow these steps:

  1. Set up SSL Certificate: Obtain an SSL certificate for your domain to enable HTTPS encryption. DreamHost offers free Let's Encrypt SSL certificates that you can install through the DreamHost control panel. This will ensure secure communication between your app and clients.
  2. Secure Database: If your NodeJS app relies on a database, make sure to properly secure it. Set strong database credentials and avoid using default usernames and passwords. Restrict access to the database and regularly update and patch your database software.
  3. Use Strong Authentication: Implement secure authentication mechanisms for your app. Avoid using plaintext passwords and consider using more secure authentication protocols such as OAuth2 or JSON Web Tokens (JWT).
  4. Enable Firewall: DreamHost provides server-level firewalls. Ensure that your NodeJS app is protected by enabling the firewall and configuring it to allow only necessary incoming and outgoing traffic. This will help prevent unauthorized access to your app.
  5. Secure File Uploads: If your app allows file uploads, validate and sanitize user inputs to prevent any malicious file uploads. Limit the types of files that can be uploaded, control file sizes, and use server-side validation to check uploaded files for potential security vulnerabilities.
  6. Regularly Update Dependencies: Keep your NodeJS dependencies up to date to ensure you're using the latest versions with the latest security patches. Vulnerabilities in outdated dependencies can lead to security breaches.
  7. Implement Security Measures in Code: Write secure code by following best practices. Sanitize inputs, avoid eval/exec, utilize prepared statements to prevent SQL injection attacks, and avoid using outdated or vulnerable libraries.
  8. Set Secure Permissions: Make sure the permissions for your app's files and directories are correctly set. Restrict write permissions where possible and ensure that only necessary permissions are granted to prevent unauthorized access.
  9. Use Logging and Monitoring: Implement logging mechanisms to track and monitor your app's activities. Regularly review logs to identify any suspicious or abnormal behavior. Consider using tools like New Relic or custom monitoring solutions to proactively monitor the app's performance and security.
  10. Regularly Backup Data: Back up your NodeJS app and its associated data to prevent any major loss. Configure automated backups through DreamHost or use external solutions to ensure data resilience.


Remember, securing a NodeJS app is an ongoing process. Stay informed about the latest security practices, regularly update your app's dependencies and libraries, and be vigilant against potential vulnerabilities and threats.
