Setup Nginx Proxy for Node.js app

Behind every major player in the cloud provider’s field, there is a hidden “magic” that makes our applications work. Most of the time, this magic is some kind of a proxy, mostly Nginx. But, how about we get our hands dirty and setup a Nginx proxy for a Node.js app, on our own server.


  • Nginx
  • Nodejs


Step 1. Create a nginx conf file for the nodejs app.

$ touch /etc/nginx/conf.d/nodejsapp.conf

Step 2. Open the file with your favorite code editor, nano, vim, whatever, and paste the following configuration:

upstream nodejsapp_upstream {

server {
    listen 80;
    server_name nodejsapp.yourdomain;

    location / {
        proxy_set_header X-Forwarded-For $remote_addr;
    	proxy_set_header Host $http_host;
    	proxy_pass http://nodejsapp_upstream;

Step 3. Save the file and test the Nginx configuration.

$ nginx -t

Expected output:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Step 4. Reload or restart Nginx.

$ systemctl reload nginx
$ systemctl restart nginx

Step 5. Now, test the proxy by opening a web browser or run curl and try to reach the domain URL defined in the nginx config above.


If you wanna integrate the Nginx proxy with the famous PM2 daemon process manager, they have a great Nginx production configuration setup example here.
