Prevent Technical Disasters While Leveraging AI Coding

// Exposed API key in client code
const API_KEY = "sk-1234567890abcdef";

// No error handling
async function fetchData() {
  const data = await fetch("/api/data");
  return data.json();
}

// Security vulnerability
app.get('/user/:id', (req, res) => {
  db.query(`SELECT * FROM users WHERE id = ${req.params.id}`);
});

// Hardcoded credentials
const dbConfig = {
  host: "production.db.example.com",
  user: "admin",
  password: "supersecret123",
  database: "users"
};

// No input validation
function processUserInput(input) {
  eval(input); // Dangerous!
}

// Insecure cookie
document.cookie = "authToken=abc123; path=/";
