Node.js provides a robust ecosystem through the installation of modules that extend capabilities. From a security point of view, this is not necessarily safe, because it provides more opportunities to open back doors.

Therefore, you should always take Node.js security seriously.
Vulnerabilities are increasing as attackers find new, clever ways to break into your apps. It’s important to protect your customers ’sensitive data. This is an open invitation: You should consider the security of your application at every phase of the development such as architecture, design, code, and finally the deployment.
