Security is crucial for any web application. Let's explore essential security practices to protect your applications.

Key Security Areas

• Authentication
• Authorization
• Data Encryption
• Input Validation

Implementation Examples

// Example of secure password hashing
const bcrypt = require("bcrypt");

async function hashPassword(password) {
  const salt = await bcrypt.genSalt(12);
  return bcrypt.hash(password, salt);
}

// Example of JWT implementation
const jwt = require("jsonwebtoken");

function generateToken(user) {
  return jwt.sign({ id: user.id, role: user.role }, process.env.JWT_SECRET, {
    expiresIn: "1h",
  });
}
