- Configure gRPC, RabbitMQ, and monorepo contract patterns for NestJS microservices. Use when setting up gRPC service-to-service calls, RabbitMQ event-driven messaging, shared contract libraries, or microservice exception handling in NestJS.
Microservices & Transport Standards
Priority: P0 (FOUNDATIONAL)
- Synchronous (RPC): Use gRPC for low-latency, internal service-to-service calls (10x faster than REST/JSON).
- Asynchronous (Events): Use RabbitMQ or Kafka for decoupling domains via fire-and-forget (
emit()).
gRPC Setup
See implementation examples
RabbitMQ Setup
See implementation examples
Monorepo Contracts
- Store all DTOs,
.protofiles, and Interfaces inlibs/contracts. - Services never import from sibling services — only from
contracts. - Semantic versioning of messages mandatory. Never change field type; add new field.
Exception Handling
Standard HttpException lost over RPC/TCP. Use RpcException with global filters:
See implementation examples
Serialization
- Apply
useGlobalPipes(new ValidationPipe({ transform: true }))inMicroserviceOptionssetup, not HTTP.
Anti-Patterns
- No cross-service imports: Services must import only from
libs/contracts, never from sibling services. - No HttpException in RPC: Use
RpcExceptionwith globalRpcExceptionFilterfor microservice errors. - No unversioned message schema: Add new fields; never change existing field types — consumers will break.

Infer the requesting operator's technical fluency from message content (never ask directly) and adapt register — business, hybrid, or technical — across SDLC workflow output. Use when starting sdlc, brainstorm-feature, plan-feature, verify-work, publish-notes, or session-report, or whenever a request's phrasing signals a non-technical or cross-stack operator.
