2. Configure nginx: Now, you’ll set up nginx to act as a reverse proxy for your Next.js app. Open the nginx configuration file:

   sudo nano /etc/nginx/sites-available/default
   

   Replace the contents with the following configuration:

   server {
       listen 80;
       server_name your-domain.com;
   
       location / {
           proxy_pass http://localhost:3000;
           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.

3. Test and restart nginx: Save the file and test the configuration:

   sudo nginx -t
   

   If everything looks good, restart nginx to apply the changes:

   sudo systemctl restart nginx
   

4. Verify the setup: Open your browser and visit your domain. You should see your Next.js app running through nginx.

Using nginx as a reverse proxy not only boosts performance but also simplifies SSL setup later. It’s a small step that makes a big difference in your hosting setup.
