The Complete Guide to API Design in 2026: REST, GraphQL, and tRPC in Production
The guide outlines the settled API landscape in 2026, with three clear patterns: REST for public APIs and microservices, GraphQL for complex data requirements, and tRPC for TypeScript-to-TypeScript full-stack applications. It emphasizes choosing based on fit rather than hype. Key REST improvements include a standardized error response format with a requestId field, which transforms debugging by linking every error to structured logs. The article recommends URL versioning (e.g., /v1/users) for major breaking changes only, with minor additions handled via query parameters. The advice is grounded in production experience, warning against hype-driven decisions.
