The MERN Stack is a popular technology stack for web development, comprising:

  • MongoDB: A robust NoSQL database.
  • Express.js: A server-side web application framework for Node.js.
  • React: A front-end JavaScript library for building user interfaces.
  • Node.js: A JavaScript runtime environment for building scalable network applications.

Webuzo on provides Webuzo pre-installed with its hosting plans, offering a seamless environment for MERN Stack development. This includes readily available applications like Node.js and MongoDB. For hosting options, visit DomainIndia's Webuzo Web Hosting.

Getting Started


Access Webuzo

  1. Access Webuzo Panel: Log into your Webuzo control panel.
  2. Configure Applications: Leverage the pre-installed Node.js and MongoDB applications for MERN Stack development.

For an extensive guide, consult A Comprehensive Index to Mastering MERN Stack.

Fetching the MERN Stack Application

Find a MERN Stack App

To select a suitable MERN Stack application from GitHub:

  1. Visit GitHub: Go to GitHub.
  2. Search for MERN Stack Applications: Use the search bar and type "MERN Stack".
  3. Evaluate Repositories: Look for repositories with good documentation, recent updates, and active maintenance. Example: MERN Boilerplate.

Clone the Repository

  1. Open Webuzo Terminal: Access the terminal in your Webuzo control panel.
  2. Navigate to the Desired Directory: Use cd to navigate to the directory where you want to clone the repository.

cd /path/to/your/directory

Clone the Repository: Use the Git clone command with the URL of the GitHub repository.

git clone

Verify the Cloned Repository: Check that the repository files are present.

ls -l

Setting Up the Environment

  1. Install Node.js and MongoDB: If not already installed, use Webuzo's application management interface to install these.

  2. Install Dependencies: Navigate to the cloned repository’s directory and install the required Node modules.

cd mern-boilerplate
npm install

  1. Configure Environment Variables: Set up necessary environment variables in a .env file if the app requires it.

  2. Start MongoDB: Ensure MongoDB is running on your Webuzo panel.

  3. Run the Application: Start the Node.js server.

npm start

Verify Application: Open your browser and navigate to the local address provided by the Node.js server to see if the application is running correctly.

This process outlines the basic steps for fetching and setting up a MERN Stack application using GitHub and Webuzo.

Configuring the Backend

Setting Up MongoDB

  1. Access MongoDB in Webuzo: Navigate to the MongoDB section in your Webuzo panel.
  2. Create a New Database: Select 'Create Database' and enter a name for your MERN application's database.
  3. Manage Database Users: Create a user and assign them to your new database with appropriate permissions.

Configuring Node.js and Express.js

  1. Edit Configuration Files: In your backend code, ensure the database connection strings point to your newly created MongoDB database.
  2. Install Backend Dependencies: Run npm install to install any additional backend dependencies.
  3. Start the Backend Server: Use node or a process manager like pm2 to start your Express.js server.

Preparing the Frontend

Setting Up React

  1. Navigate to Frontend Directory: Change to the directory containing your React application.

cd path/to/frontend

  1. Install Dependencies: Run npm install to install the necessary React dependencies.
  2. Configure Environment Variables: Set up any necessary API endpoints or external service URLs in your .env file or directly in your React app.

Building and Testing

Build the Application: Use the React script to build your application.

npm run build

Test Locally: Start the React development server to test the application locally.

npm start

Finalize Deployment: Once tested, deploy the build folder contents to your Webuzo public_html directory or a specific subdirectory.

These steps provide a comprehensive guide for setting up the backend and frontend of a MERN Stack application on a Webuzo hosted environment

Deployment Process

Deploying the Backend (Node.js and Express)

  1. Upload Backend Code: Use FTP or Webuzo's file manager to upload your backend code to a specific directory in your hosting space.
  2. Server Configuration:
    • Set up a reverse proxy, if necessary, to direct traffic to your Node.js app.
    • Configure your web server (Apache or Nginx) through Webuzo to work with Node.js.
  3. Start the Backend Service:
    • Use a process manager like pm2 to start your Node.js application.
    • Ensure it restarts automatically after reboots or crashes.

Deploying the Frontend (React)

  1. Build React App:
    • Run npm run build in your local React app directory.
    • This creates a build folder with optimized production files.
  2. Upload Frontend Files:
    • Upload the contents of the build folder to the public_html directory or a subdirectory on your Webuzo hosting environment.
  3. Configure Web Server:
    • Adjust your web server settings in Webuzo to serve the React application correctly.
    • Ensure the server points to the right directory containing your built React app.

After completing these steps, both the backend and frontend of your MERN Stack application should be live and accessible on your Webuzo hosting platform.

  1. Functional Testing: Navigate to your application's URL and test all features, including database interactions, API calls, and user interface elements.
  2. Console and Network Inspection: Use browser developer tools to inspect console logs and network requests for errors.
  3. Backend Testing: Check server logs for any runtime errors or warnings.

Troubleshooting Common Issues

  • Database Connection Issues: Verify database credentials and connection strings in your backend configuration.
  • Frontend Loading Errors: Ensure all static files are correctly uploaded and paths are correctly referenced.
  • API Endpoint Failures: Test API endpoints separately to ensure they respond as expected.

Advanced Configurations

Custom Domain Setup

  1. Add Domain in Webuzo: Navigate to the domain management section and add your custom domain.
  2. Update DNS Settings: Point your domain's DNS records to your Webuzo server's IP address.

SSL Configuration

  1. Access SSL Features: In Webuzo, navigate to the SSL/TLS section.
  2. Install Let’s Encrypt or Zero SSL: Follow Webuzo’s prompts to generate and install an SSL certificate for your domain.
  3. Verify HTTPS: Ensure your application is accessible via https:// and all resources are loaded securely.

Implementing these testing and advanced configuration steps ensures a fully functional and secure MERN stack application on your Webuzo hosting.

Maintenance and Updates

Application Updates

  • Regular Monitoring: Keep track of updates for MongoDB, Express.js, React, and Node.js.
  • Test Before Updating: Implement changes in a staging environment before applying them to live.
  • Automate Where Possible: Use tools like Webuzo to automate updates for underlying server components.

Performance Tuning

  • Monitoring Tools: Utilize Webuzo’s monitoring tools or integrate third-party services to track application performance.
  • Optimize Database: Regularly review and optimize MongoDB for efficient data handling.
  • Code Profiling: Regularly review your Node.js and React code for performance improvements.



Deploying a MERN Stack application on’s Webuzo hosting combines powerful technologies with ease of management, resulting in efficient, scalable web applications.
