REST and GraphQL API design principles for building scalable, developer-friendly APIs. Master REST and GraphQL API design principles to build intuitive, scalable, and maintainable APIs that delight developers and stand the test of time. Resource-Oriented Architecture HTTP Methods Semantics: Schema-First Development Query Structure: URL Versioning: Header Versioning: Query Parameter Versioning: - Covers resource-oriented REST patterns including HTTP method semantics, URL design, pagination, filtering, and error handling with consistent status codes - Includes GraphQL schema-first development with type definitions, resolver patterns, Relay-style pagination, and DataLoader implementation for N+1 prevention - Provides versioning strategies (URL, header, query parameter) and HATEOAS patterns for hypermedia-driven APIs - Addresses common pitfalls like over-fetching, breaking changes, inconsistent error formats, and tight coupling between API structure and database schema - Best practices for both paradigms covering naming conventions, statelessness, rate limiting, documentation, and deprecation strategies - Designing new REST or GraphQL APIs - Refactoring existing APIs for better usability - Establishing API design standards for your team - Reviewing API specifications before implementation - Migrating between API paradigms (REST to GraphQL, etc.) - Creating developer-friendly API...
