Node Security

 Node Security:

 NGINX

-Nowadays node.js is the leading tool for creating server applications in Javascript and offering the functionality of both a web server and an application server.

-But nodejs has some vulnerabilities that can cause unsatisfactory performance or even crashes with node-based applications 

-At the same time we can overcome those problems by caching static content, reverse proxy and load balance among multiple application servers, and managing port contention using NGINX we pronounce like("engine X").

-Nginx is an excellent tool for increasing node.js performance. It is an HTTP and reverse proxy server, a mail proxy server, and a generic TCP/UDP proxy server originally written by Igor Sysoev.

REVERSE PROXY:

-As traffic to your applications increases the best approach as a reverse proxy server in front of the node.js server to LOAD BALANCE traffic across the servers. this is the core use case of Nginx in node.js applications.
