1. Helmet
Helmet is a middleware that helps to protect your application from a variety of common web vulnerabilities, such as cross-site scripting (XSS) and clickjacking. It does this by setting a number of security headers by default, and allowing you to customize the headers to meet your specific needs.
// ...
const helmet = require('helmet');
app.use(helmet());
// ...
2. Express-rate-limit
Express-rate-limit is a middleware that helps to protect your application from denial-of-service (DoS) attacks. It does this by limiting the number of requests that a client can make to your application within a certain period of time.
const rateLimit = require('express-rate-limit');
const apiLimiter = rateLimit({
windowMs: 15 * 60 * 1000, // 15 minutes
max: 100, // Limit each IP to 100 requests per window
});
app.use('/api', apiLimiter);
3. Express-validator
Express-validator is a middleware that helps to validate user input and prevent common attacks such as SQL injection and cross-site scripting. It does this by providing a number of built-in validation checks, and allowing you to create custom validation checks for your specific needs.
const expressValidator = require('express-validator');
app.use(expressValidator());4. Xss-clean
Xss-clean is a middleware that helps to protect your application from cross-site scripting (XSS) attacks. It does this by sanitizing user input and removing any malicious code.
const xssClean = require('xss-clean');
app.use(xssClean());
5. Safe-regex
Safe-regex is a library that helps to prevent regular expression denial-of-service (ReDoS) attacks. It does this by providing a number of built-in safe regular expressions, and allowing you to create custom safe regular expressions.
const safeRegex = require('safe-regex');
const emailRegex = safeRegex({
source: '\\A[a-z0-9._%+-]+@[a-z0-9.-]+\\.[a-z]{2,}\\z',
flags: 'i',
});
const emailAddress = req.body.email;
if (!emailRegex.test(emailAddress)) {
return res.status(400).json({ error: 'Invalid email address' });
}
6. Hpp
Hpp is a middleware that helps to protect your application from HTTP parameter pollution attacks. It does this by sanitizing HTTP parameters before they are processed by your application.
const hpp = require('hpp');
app.use(hpp());
7. Bcrypt
Bcrypt is a password hashing library that helps to protect your users’ passwords from being compromised. It does this by using a salt and a number of hashing rounds to create a unique and secure hash for each password.
const bcrypt = require('bcrypt');
const saltRounds = 10;
const hashPassword = async (password) => {
const salt = await bcrypt.genSalt(saltRounds);
const hash = await bcrypt.hash(password, salt);
return hash;
};
const verifyPassword = async (password, hash) => {
const result = await bcrypt.compare(password, hash);
return result;
};
8. Jsonwebtoken
Jsonwebtoken (JWT) is a standard for creating and verifying tokens that contain claims about the user. JWTs are often used for authentication and authorization in web applications.
const jwt = require('jsonwebtoken');
const secret = 'my-secret-key';
const generateJwt = (payload) => {
const token = jwt.sign(payload, secret, {
algorithm: 'HS256',
expiresIn: '1h',
});
return token;
};
const verifyJwt = (token) => {
const payload = jwt.verify(token, secret, {
algorithm: 'HS256',
});
return payload;
};
9. Passport
Passport is a popular authentication middleware for Node.js applications. It supports a variety of authentication providers, including Google, Facebook, and Twitter.
const passport = require('passport');
// Initialize Passport
passport.initialize();
// Define a strategy
passport.use(new GoogleStrategy({
clientID: 'my-client-id',
clientSecret: 'my-client-secret',
callbackURL: 'http://localhost:3000/auth/google/callback',
}));
// Create a route for authentication
app.get('/auth/google', passport.authenticate('google'));
// Create a route for authentication callback
app.get('/auth/google/callback', passport.authenticate('google', {
successRedirect: '/',
failureRedirect: '/login',
}));
10. Csrf
Csrf is a middleware that helps to protect your application from cross-site request forgery (CSRF) attacks. It does this by generating a token and including it in all of your application’s forms. When a user submits a form, the token is verified to ensure that the request is coming from the user’s browser and not from a malicious third party.
const csrf = require('csurf');
// Create a CSRF protection middleware
const csrfMiddleware = csrf({
cookie: true,
});
// Apply the CSRF protection middleware to all routes
app.use(csrfMiddleware);
11. Express-session
Express-session is a middleware that helps to manage user sessions in Node.js applications. It does this by storing session data in a cookie or in memory.
const expressSession = require('express-session');
// Create a session middleware
const sessionMiddleware = expressSession({
secret: 'my-secret-key',
resave: false,
saveUninitialized: false,
});
// Apply the session middleware to all routes
app.use(sessionMiddleware);
12. Helmet-csp
Helmet-csp is a middleware that helps to implement a content security policy (CSP) in Node.js applications.
const helmetCsp = require('helmet-csp');
app.use(helmetCsp({
directives: {
defaultSrc: ["'self'"],
scriptSrc: ["'self'", "'unsafe-inline'"],
styleSrc: ["'self'", "'unsafe-inline'"],
}
})
);
13. Express-mongo-sanitize
Express-mongo-sanitize is a middleware that helps to sanitize MongoDB queries and prevent object injection attacks.
const expressMongoSanitize = require('express-mongo-sanitize');
app.use(expressMongoSanitize());
14. Node-forge
Node-forge is a cryptography library that can be used for a variety of tasks, such as generating and verifying digital signatures.
const forge = require('node-forge');
forge.options.usePureJavaScript = true;
15. Owasp-sessions
Owasp-sessions is a middleware that provides secure session management features.
