Node.js Backend API Development FAQs
REST APIs follow resource-oriented design with fixed endpoints and HTTP methods, while GraphQL provides a single endpoint with flexible querying capabilities. REST is better for simple, cacheable operations, while GraphQL excels at complex data requirements and reducing over-fetching. We help choose the right approach based on your specific use case, data complexity, and client requirements.
We implement versioning strategies including URI versioning (/v1/resource), header versioning, and content negotiation. We maintain backward compatibility through careful API design, deprecation policies, and version migration strategies. Our approach ensures existing clients continue working while new features can be introduced safely.
We implement comprehensive security including JWT authentication, input validation, rate limiting, CORS configuration, HTTPS enforcement, and protection against common vulnerabilities (SQL injection, XSS, CSRF). We also conduct security audits, implement proper error handling, and follow OWASP security guidelines to protect your APIs and data.
We optimize performance through multiple strategies including database query optimization, caching (Redis, in-memory), connection pooling, load balancing, and efficient algorithms. We implement monitoring to identify bottlenecks, use clustering for multi-core utilization, and design APIs with performance in mind from the beginning to handle high traffic loads efficiently.
