Sails.js is a powerful MVC framework for Node.js that makes it easy to build custom, enterprise-grade Node.js applications. In this guide, we will walk through the steps to install Sails.js on Debian 11 and configure it to run behind Nginx.

Step 1: Update Your System

Start by ensuring your system is up to date:

sudo apt update && sudo apt upgrade -y

Step 2: Install Node.js and npm

Sails.js requires Node.js and npm (Node Package Manager). You can install them using the following commands:

sudo apt install -y nodejs npm

Step 3: Install Sails.js

Once Node.js and npm are installed, you can install Sails.js globally:

sudo npm install -g sails

Step 4: Create a New Sails.js Application

Create a new Sails.js project by running:

sails new mySailsApp

Navigate to your newly created project directory:

cd mySailsApp

Step 5: Configure the Application

Before starting the application, configure your Sails.js app by editing the config/env/production.js file to set the appropriate environment settings:

nano config/env/production.js

Make sure to configure the necessary database settings and other production configurations.

Step 6: Start the Sails.js Application

You can start your Sails.js application using:

sails lift

Your application should now be running on port 1337 by default.

Step 7: Install and Configure Nginx

Install Nginx if you haven't done so already:

sudo apt install -y nginx

Create a new Nginx configuration file for your Sails.js app:

sudo nano /etc/nginx/sites-available/sails.conf

Add the following configuration:

server {
        listen 80;
        server_name your_domain.com;  # Replace with your domain

        location / {
            proxy_pass http://localhost:1337;  # Sails.js runs on port 1337
            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;
        }
    }

Replace your_domain.com with your actual domain name.

Step 8: Enable the Nginx Configuration

Enable the new configuration by creating a symbolic link:

sudo ln -s /etc/nginx/sites-available/sails.conf /etc/nginx/sites-enabled/

Step 9: Restart Nginx

Restart Nginx to apply the changes:

sudo systemctl restart nginx

Step 10: Access Your Sails.js Application

Now you can access your Sails.js application by navigating to:

http://your_domain.com

Conclusion

You have successfully installed the Sails.js MVC framework and configured it to run behind Nginx on Debian 11. This setup provides a robust foundation for building web applications.
