Node.js Security Headers with Helmet

Adding Security Headers

Node.js security headers use helmet for HTTP protection.

Introduction to Node.js Security Headers

In web development, security is a top priority, especially when dealing with sensitive user data. Node.js applications are no exception, and one effective way to enhance their security is by implementing security headers. Security headers provide an additional layer of protection by controlling how the browser should behave on your website. In this guide, we'll explore how to use Helmet, a popular middleware for Node.js, to implement these headers.

What is Helmet?

Helmet is a Node.js middleware that helps secure your Express.js applications by setting various HTTP headers. It is a collection of smaller middleware functions that set security-related HTTP headers. These headers can help prevent common vulnerabilities such as cross-site scripting (XSS), clickjacking, and others.

Installing Helmet

To get started with Helmet, you need to install it via npm. Ensure you have Node.js and npm installed on your system.
