API Security Best Practices

Security is critical for any API. Here are essential practices to secure your APIs.

Authentication and Authorization

Use JWT Tokens

JWT tokens provide stateless authentication:

const token = jwt.sign({ userId: user.id }, secret, { expiresIn: '1h' });

Implement Rate Limiting

Protect against abuse:

const rateLimiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100 // limit each IP to 100 requests per windowMs
});

Input Validation

Always validate and sanitize input:

const schema = z.object({
  email: z.string().email(),
  password: z.string().min(8)
});

HTTPS Only

Always use HTTPS in production to encrypt data in transit.

Conclusion

Security should be built into your API from the start. Follow these practices to keep your APIs secure.
