SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables building efficient inter-service communication using gRPC in Rails, including unary and streaming RPCs for high-throughput APIs.

Core Features & Use Cases

Proto-Driven Contracts: Define services in .proto files.
Unary & Streaming RPCs: Implement both request/response and streaming patterns.
Interceptors: Add authentication and logging cross-cutting concerns.
gRPC Client/Server: Provide both server-side handlers and client stubs.
Error Handling: Use appropriate gRPC status codes for failures.

Quick Start

Define a .proto file, 2) generate Ruby code with protoc, 3) implement services, 4) run tests.

FAQPage Schema

How do I implement gRPC services in a Rails application?▼

gRPC services in Rails require Protocol Buffer definitions compiled to Ruby code, then implemented as service handlers. Define your .proto file with service methods, generate Ruby stubs with protoc, create handler classes in your Rails app, and run a gRPC server alongside or integrated with Rails to handle incoming requests.

When should I use gRPC instead of REST APIs?▼

gRPC excels for high-throughput inter-service communication, especially with streaming data or polyglot microservices. Use it when REST latency or binary protocol efficiency matters, when you need server and client streaming, or when services are tightly coupled and can share Protocol Buffer contracts across language boundaries.

How do I add authentication and logging to gRPC services?▼

gRPC interceptors provide cross-cutting concerns like authentication and logging. Implement server and client interceptors to inspect or modify requests and responses before they reach handlers, enabling centralized policy enforcement without duplicating code in each service method.

Can I use both unary and streaming RPCs in the same gRPC service?▼

Yes. Protocol Buffers support unary (single request/response), server streaming (one request, many responses), client streaming (many requests, one response), and bidirectional streaming. Define each RPC type in your .proto service definition and implement corresponding handler logic in Rails.

What gRPC status codes should I use for error handling?▼

gRPC defines standard status codes (OK, CANCELLED, UNKNOWN, INVALID_ARGUMENT, etc.) for different failure scenarios. Use appropriate codes in your service handlers to signal errors to clients; Rails gRPC handlers should raise exceptions mapped to these codes rather than returning HTTP-style status numbers.

Do I need a separate server process to run gRPC alongside Rails?▼

gRPC can run as a separate process or integrated within Rails. Most Rails gRPC setups run it as a dedicated server process on a different port than HTTP, though some libraries provide middleware integration. The choice depends on your deployment model and whether you want to isolate gRPC traffic.
