Implement robust security in your APIs with JWT, OAuth 2.0, rate limiting, and security best practices to protect against common vulnerabilities.
API Security Fundamentals
Security should never be an afterthought. Let's build APIs that are secure by design.
Authentication Strategies
Implement JWT for stateless authentication, or use OAuth 2.0 for third-party integrations.
Authorization Patterns
Use RBAC (Role-Based Access Control) or ABAC (Attribute-Based Access Control) for fine-grained permissions.
Rate Limiting
Protect your API from abuse with rate limiting using Redis and tools like express-rate-limit.
Input Validation
Never trust user input. Validate and sanitize everything using libraries like Joi or class-validator.
Security Headers
Implement CORS, CSP, HSTS, and other security headers to protect against common attacks.
