🤖Configure Backend (API)

After installing Nginx, create the Backend reverse-proxy configuration file using the command:

nano /etc/nginx/sites-available/api.domain.com.conf

Paste the configuration code below and change the IP to your machine's IP. Remember to add the port :3333 at the end, or if you used another port, put the port correctly.

server {
   server_name 0.0.0.0:3333; #YourIP, example: 144.87.33.65:3333
   location / {
     proxy_pass http://localhost:3333;
     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;
  }
}

Ctrl + X and type Y hit Enter to save config file.

Link the file to nginx enabled section.

ln -s /etc/nginx/sites-available/api.domain.com.conf /etc/nginx/sites-enabled/api.domain.com.conf
