11 minutes read

To publish a Node.js application on DreamHost, follow these steps:

  1. Log in to your DreamHost account and navigate to the panel.
  2. In the left-hand menu, click on "Domains" and select "Manage Domains" from the dropdown.
  3. Find the domain/subdomain where you want to publish your Node.js app and click on the "Edit" button next to it.
  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:
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.

How to configure reverse proxy for a NodeJS app on DreamHost?

To configure reverse proxy for a NodeJS app on DreamHost, follow these steps:

  1. Log in to your DreamHost panel and navigate to the "Domains" section.
  2. Click on the domain where your NodeJS app is hosted.
  3. Scroll down to the "Web Options" section and click on the "Edit" button for the domain.
  4. In the "Web Directory" field, ensure that your NodeJS app is set up in a subdirectory of your domain. For example, if your domain is "" and your NodeJS app is in a directory called "myapp", the "Web Directory" should be "/myapp".
  5. Save the changes and go back to the main domain management page.
  6. Scroll down to the "Fully Hosted Domains" section and click on the "Edit" button for your domain.
  7. In the "Extra Web Security" section, enable the "Proxy" option.
  8. In the "Proxy Destination URL" field, enter the URL where your NodeJS app is running. For example, if your NodeJS app is running on "http://localhost:3000", enter "http://localhost:3000" as the destination URL.
  9. Save the changes.
  10. Wait for a few minutes for the changes to take effect.

After following these steps, your NodeJS app will now be accessible through your domain, making use of the reverse proxy configuration set up in DreamHost.

How to install required dependencies for a NodeJS app on DreamHost?

To install the required dependencies for a Node.js app on DreamHost, you can follow these steps:

  1. Connect to your DreamHost server using SSH.
  2. Navigate to the root directory of your Node.js application by using the cd command. For example: cd /path/to/your/node/app
  3. Run the command npm install to install the dependencies listed in your package.json file. This will download and install the required dependencies from the npm registry. If your project also contains a package-lock.json file, running npm install will ensure that the same versions of dependencies are installed across different environments.
  4. Wait for the installation process to complete. This may take a few moments depending on the number and size of your dependencies.
  5. Once the installation is finished, your dependencies will be installed in a node_modules directory in your project folder.

That's it! Your Node.js app is now ready to use the installed dependencies.

How to configure session management for a NodeJS app on DreamHost?

To configure session management for a Node.js app on DreamHost, you can follow these steps:

  1. Create a new Node.js application or navigate to an existing one on DreamHost.
  2. Open the terminal or SSH into your DreamHost server.
  3. Install the necessary packages for session management. You can use npm to install popular packages like "express-session" or "cookie-session". For example, run the command: npm install express-session
  4. In your Node.js application, require the session management package and initialize it with the desired configurations. Here's an example using the "express-session" package:
const session = require('express-session');
const express = require('express');
const app = express();

  secret: 'your-secret-key',
  resave: false,
  saveUninitialized: false,

The secret option should be replaced with a unique and secure key. The other options are optional and can be customized as needed.

  1. Once your session middleware is set up, you can start using it in your routes or middleware functions. For example:
app.get('/login', (req, res) => {
  req.session.username = 'John';
  res.send('Logged in');

app.get('/profile', (req, res) => {
  const username = req.session.username;
  res.send(`Welcome back, ${username}`);

In this example, the req.session object is used to store and access session data.

  1. Save your changes and deploy your Node.js app on DreamHost.

That's it! You have now configured session management for your Node.js app on DreamHost. Remember to adapt these instructions to your specific use case and package preferences.
