What Is Helmet JS?

Helmet.js Is A Middleware For Express.js That Helps Secure Your Applications By Setting Various HTTP Headers.

const helmet = require('helmet');  const express = require('express');  const app = express();  app.use(helmet());

Benefits Of Using Helmet JS

⚡ Prevents Cross-Site Scripting (XSS): Helps Mitigate XSS Attacks. ⚡  Content Security Policy (CSP): Controls The  Resources The User Agent Is Allowed To Load. ⚡  Clickjacking Protection: Prevents Clickjacking Attacks By Disabling Iframes.

app.use(helmet.xssFilter()); app.use(helmet.frameguard({ action: 'deny' }));

Configuring Helmet JS 

Customizing Helmet: You Can Enable Or Disable Specific Helmet Features Based On Your Needs.

Customize Helmet To Fit Your Application's Specific Security Requirements.

app.use(helmet({   contentSecurityPolicy: false,    frameguard: { action: 'sameorigin' }  ));

Helmet JS And Content Security Policy (CSP) 

Setting CSP With Helmet: You Can Define A Content Security Policy To Control Resource Loading.

CSP Helps Protect Against XSS Attacks By Restricting Sources For Scripts And Other Content.

app.use(helmet.contentSecurityPolicy({   directives: {     defaultSrc: ["'self'"],     scriptSrc: ["'self'", 'trusted.com'],   } }));

Combining Helmet With Other Security Practices 

Use Helmet In Conjunction With Other Security Measures Like HTTPS, Rate Limiting, And Input Validation.

Combining Helmet With Other Security Tools Maximizes The Security Of Your Application.

const rateLimit = require('express-rate-limit');  app.use(rateLimit({ windowMs: 15 * 60 * 1000, max: 100 }));  app.use(helmet());
