Agent-skills-standard nestjs-transport

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. (triggers: main.ts, **/*.controller.ts, Transport.GRPC, Transport.RMQ, MicroserviceOptions)

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,
```
.proto
```
files, and Interfaces in
```
libs/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 }))

MicroserviceOptions

setup, not HTTP.

Anti-Patterns

No cross-service imports: Services must import only from
```
libs/contracts
```
, never from sibling services.
No HttpException in RPC: Use
```
RpcException
```
with global
```
RpcExceptionFilter
```
for microservice errors.
No unversioned message schema: Add new fields; never change existing field types — consumers will break.
