The MEAN stack is a powerful, modern approach to web development that combines MongoDB, Express.js, Angular, and Node.js. Together, these technologies allow developers to create fast and efficient full-stack applications. In this article, we’ll explore how to deploy a MEAN stack application with Nginx, including the benefits and a step-by-step guide tailored for newcomers.

Benefits of Using the MEAN Stack with Nginx

• Single Language Development: JavaScript is used across the entire stack, making it simpler for developers to work within a single language ecosystem.
• Performance: Node.js provides non-blocking I/O operations, which, when combined with Nginx’s event-driven architecture, results in high-performance applications.
• Scalability: Both Nginx and Node.js are known for their ability to handle large numbers of concurrent connections, making this setup ideal for scalable applications.
• Flexibility: MongoDB’s schema-less structure allows for flexible data storage, while Angular offers a robust framework for building dynamic client-side web applications.

Setting Up the MEAN Stack on Nginx

Before we begin, ensure that you have Nginx, Node.js, and MongoDB installed on your server. For this tutorial, we’ll assume you’re using a Linux-based server.

Step 1: Install MongoDB

MongoDB is the database component of the MEAN stack. Install MongoDB with the following command:

sudo apt-get install -y mongodb

Ensure the MongoDB service is started:

sudo systemctl start mongodb
sudo systemctl enable mongodb

Step 2: Install Node.js and NPM

Node.js is the runtime environment for running JavaScript on the server, and NPM is the package manager for Node.js. Install them with:

sudo apt-get install -y nodejs npm

Step 3: Set Up Your MEAN Stack Application

Clone your application’s repository or create a new MEAN stack application. Make sure your application’s entry point (usually server.js or app.js) is configured correctly.

Step 4: Install Node.js Dependencies

Navigate to your application’s directory and run:

npm install

This will install all the necessary Node.js dependencies defined in your package.json file.

Step 5: Configure Nginx as a Reverse Proxy

Nginx will act as a reverse proxy, forwarding client requests to your Node.js application. Create a new Nginx server block configuration:

sudo nano /etc/nginx/sites-available/yourdomain.com

Add the following server block, replacing yourdomain.com and PORT with your domain name and the port your Node.js app runs on:

server {
    listen 80;
    server_name yourdomain.com www.yourdomain.com;

    location / {
        proxy_pass http://localhost:PORT;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

Symlink the configuration to the sites-enabled directory and test the Nginx configuration:

sudo ln -s /etc/nginx/sites-available/yourdomain.com /etc/nginx/sites-enabled/
sudo nginx -t

If everything is OK, restart Nginx:

sudo systemctl restart nginx

Step 6: Start Your Node.js Application

Start your Node.js application by running:

node server.js

For a production environment, consider using a process manager like PM2 to keep your application running in the background and to start automatically on server reboots.

Step 7: Access Your MEAN Stack Application

Open your web browser and navigate to http://yourdomain.com. You should now see your MEAN stack application up and running, served through Nginx.

Shape.host Services, Linux SSD Vps

For optimal performance and reliability, consider hosting your MEAN stack application on a Linux SSD VPS from Shape.host. Their SSD-powered hosting solutions offer high-speed data access, ensuring that your MEAN stack applications run smoothly with minimal latency.
