9 Tools to Protect NodeJS from Hackers

What is NodeJS?

NodJS is an environment for web servers. It is an open-source method. It is free of cost in a server environment compatible with various platforms like Linux, Windows, Unix, Mac OS X, etc. It uses JavaScript for operation. 

Operation of NodeJS

The basic operation of a web server involves sending files to the computer’s file system. Then the system opens the files and reads them accordingly. The same content is sent to the client to get prepared to handle the next request. On the other hand, a NodeJS works with more pace. It sends the files to the computer’s file system and prepares itself to handle the next request. Meanwhile, the server opens up the files, reads them, and sends them to the clients. It helps to eliminate the waiting time and prepares itself to handle the next request immediately. Therefore, various platforms prefer using NodeJS for their webserver to stay protected as it works single-threaded, non-blocking, and has non-parallel programming which makes it memory efficient. 

9 Tools to Protect and Ensure Smooth Functioning of NodeJS 

Being a beneficial web server environment there are high chances of it being hacked. Hackers are always in awe to hack such multi-functioning, time-saving, and beneficial things.
