WebServicesAndApis Hub

This cluster covers the patterns and protocols for service-to-service and client-server communication on the web. The orientation is design — what each pattern is for, when to use it, and the failure modes that catch teams that pick the wrong tool.

Protocol comparison

• ApiProtocolComparison — REST vs. GraphQL vs. gRPC vs. SOAP: when each is right
• GraphQlFundamentals — Schema, queries, mutations, the N+1 problem
• HateoasAndHypermediaApis — Why HATEOAS sounded good and rarely shipped
• HttpTwoAndHttpThree — Multiplexing, server push, QUIC, and what changed

Patterns that scale

• IdempotencyPatterns — Idempotency keys, the right level of granularity
• PaginationStrategies — Offset vs. cursor, ordering stability, edge cases
• BatchApiDesign — Batch endpoints, partial failure handling
• FileUploadPatterns — Multipart, signed URLs, resumable uploads

Real-time communication

• WebSocketPatterns — Connection management, backpressure, fallback strategies
• ServerSentEventsPatterns — When SSE beats WebSockets
• WebhookPatterns — Delivery guarantees, retry, signature verification

Adjacent clusters

• Java Hub — Server-side implementation
• Frontend Development Hub — Client-side consumption
• DevOps and SRE Hub — API operability concerns
• Networking Hub — Protocol-level layer below APIs
