Securing a Node.js Application: A Practical WalkthroughMany developers build functional applications quickly but overlook security until it is too late. To illustrate how to fix this, I will walk through a realistic scenario involving a small Node.js and Express web application. We will move from a vulnerable baseline to a hardened production-ready state, focusing on specific code changes rather than abstract theory. This approach uses the OWASP Top 10 as a practical checklist, which is a standard list of the most critical web application security risks.Identifying the Vulnerable StackOur starting point is a simple Express application that works but is...
