Node.js Security Basics for Safe APIs

Node.js Security Practices

Node.js security prevents XSS and sanitizes inputs for safe APIs.

Understanding Node.js Security

Node.js is a powerful platform for building web applications. However, like any other technology, it is vulnerable to certain security threats such as Cross-Site Scripting (XSS) and SQL Injection. Understanding these vulnerabilities and implementing security measures is crucial for developing safe and secure applications.

Preventing Cross-Site Scripting (XSS)

Cross-Site Scripting (XSS) is a type of security vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. This can lead to data theft, session hijacking, and other malicious activities. To prevent XSS, it is essential to:

Sanitize user inputs.
Use content security policies.
Escape output data.
