Production Setup with Nginx

Nginx as an HTTP proxy

This is the common way of handling a nodejs server so that it shows up on the port 80. Usually, your web server will run on a random port (for example 3001). The benefits of this, is that the nodejs web server will run from a user of your choice instead of root. Nginx will then forward the 80 port to the one of your choice (here 3001).

Just add a virtual host (best known as “server block” in the nginx world):


upstream my_nodejs_upstream {
    server 127.0.0.1:3001;
    keepalive 64;
}

server {
    listen 80;
    server_name my_nodejs_server;
    root /home/www/project_root;
    
    location / {
    	proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    	proxy_set_header Host $http_host;
    	proxy_set_header X-NginX-Proxy true;
    	proxy_http_version 1.1;
    	proxy_set_header Upgrade $http_upgrade;
    	proxy_set_header Connection "upgrade";
    	proxy_max_temp_file_size 0;
    	proxy_pass http://my_nodejs_upstream/;
    	proxy_redirect off;
    	proxy_read_timeout 240s;
    }
}

Learn more on those options on the nginx docs! With this, all you need is a PM2-started nodejs server running on the port 3001 and you’ve a production-ready http server!
