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](ApiProtocolComparison) — REST vs. GraphQL vs. gRPC vs. SOAP: when each is right

- [GraphQlFundamentals](GraphQlFundamentals) — Schema, queries, mutations, the N+1 problem

- [HateoasAndHypermediaApis](HateoasAndHypermediaApis) — Why HATEOAS sounded good and rarely shipped

- [HttpTwoAndHttpThree](HttpTwoAndHttpThree) — Multiplexing, server push, QUIC, and what changed

Patterns that scale

- [IdempotencyPatterns](IdempotencyPatterns) — Idempotency keys, the right level of granularity

- [PaginationStrategies](PaginationStrategies) — Offset vs. cursor, ordering stability, edge cases

- [BatchApiDesign](BatchApiDesign) — Batch endpoints, partial failure handling

- [FileUploadPatterns](FileUploadPatterns) — Multipart, signed URLs, resumable uploads

Real-time communication

- [WebSocketPatterns](WebSocketPatterns) — Connection management, backpressure, fallback strategies

- [ServerSentEventsPatterns](ServerSentEventsPatterns) — When SSE beats WebSockets

- [WebhookPatterns](WebhookPatterns) — Delivery guarantees, retry, signature verification

Adjacent clusters
